April 6: flyby

April 10: splashdown

After that, the exciting work will be in Starship making LEO and testing propellant transfer (a humanity first) [1] and Blue Origin testing its rocket and lunar lander [2], both scheduled for 2026, to enable Artemis II (EDIT: III), currently scheduled—optimistically, in my opinion—for next year.

  • Starship "making LEO" is not a significant challenge--the existing flights have explicitly targeted a (very slightly) suborbital trajectory. They could have done otherwise at any point, but for now it's more important to guarantee that the stage comes down immediately. None of their current objectives require more than ~1/2 of an orbit.

    Starship v3 flying will be a significant leap, though. It's the first with the Raptor v3 engines and has many other improvements as well, such as updated grid fins and hot staging ring. It will be the first that achieves close to the intended capacity of ~100 tons.

    Propellant transfer is indeed a significant challenge. They have already demonstrated internal transfers between tanks, but not between spacecraft.

    Very exciting times ahead!

    • > Starship "making LEO" is not a significant challenge

      Of course it is. I say this as someone who sturdied astronautics.

      You’re broadly correct, though. My point is the action shifts to Hawthorne and West Texas for the next year or so. Then pivots back to NASA for Artemis IV.

    • I was curious since I hadn't heard from Starship in a while, but by the looks of it they plan to launch the first V3 later this month!

    • Their objectives keep shifting and starship is far behind schedule. Sure, it's a success if you keep objectives small. They could have tried for LEO ages ago but didn't. Each launch should maximize learning and having small objectives is anathema to that. And very wasteful.

    • How do they hope to make prop transfer work without a working heat shield to enable reuse of the tankers? Unless SpaceX pulls a hat trick, Starship is borderline useless.

  • >> Starship making LEO and testing propellant transfer (a humanity first)

    No. We have to stop listing to AI and twitter idiots trying to upsell stories into "firsts". The first propellant transfer, the first refueling of a spacecraft on orbit, was by the soviets nearly 50 years ago.

    "Progress 1 was the first of twelve Progress spacecraft used to supply the Salyut 6 space station between 1978 and 1981.[6] Its payload of 2,300 kilograms (5,100 lb) consisted of 1,000 kilograms (2,200 lb) of propellant and oxygen, as well as 1,300 kilograms (2,900 lb) of food, replacement parts, scientific instruments, and other supplies. Whilst Progress 1 was docked, the EO-1 crew, consisting of cosmonauts Yuri Romanenko and Georgi Grechko, was aboard the station. Progress 1 demonstrated the capability to refuel a spacecraft on orbit, critical for long-term station operations.[11] Once the cosmonauts had unloaded the cargo delivered by Progress 1, they loaded refuse onto the freighter for disposal."

    https://en.wikipedia.org/wiki/Progress_1

    If SpaceX wants a first, then it would be the first transfer of cryogenic fuel. But even that could be debated as arguably Shuttle "transferred" cryogenic fuel between the tank and the orbiter during the launch process. So SpaceX might get the first of (cryogenic + on-orbit). Any simplification is a denial of what has already been done.

  • I think you meant Artemis III in your comment. Good info though, didn't realize they were relying on those two other projects for the next one.

  • Starship is just obscene. The thing is never going to work for its designed purpose once you understand what the mission looks like (basically insane amount of refuel dockings while the thing is in orbit)

    • > insane amount of refuel dockings while the thing is in orbit

      What's wrong with this? Lots of launches is fine until we build the scale required to make a proper depot worthwhile. (Which, by the way, is part of Artemis's plans. Though currently it looks like a bunch of glued-together Starship tankers.)

    • Going to the Moon or Mars is a trojan horse.

      Starship's true purpose is to compete with airlines in trans oceanic flights.

      Musk has said so many times but then he intentionally obfuscates it with all the Mars and Moon talk.

      But remember that you heard this before it was widely realized to be true; Starship isn't about going to Mars. Starship is about going to China.

I will be watching the launch from Europe, so it will be not earlier than half past midnight for us. My kids (9 and 10) are sleeping on the couch in front of the projection screen, so that they do not even have to get up when I wake them up at midnight, which I promised.

Just wanted to add my grain of positivity here. Godspeed Artemis 2!

Even though you could question the whole Artemis concept, it's still extremely exciting watching the countdown with my son. I just missed the original Apollo flights and had assumed I would never see a moon landing in my lifetime. We may well not have a landing for quite some time yet, but it's still cool to see a Moon bound rocket standing on the launchpad...

  • I don't know if it's feasible for you, but if you can, try to take your kid to see a live rocket launch. The TV is grossly unable to display how awesome these things are in person.

    • Concur. My kids and watched a “small” Falcon 9 launch from the mainland park nearest the pad at Cape Canaveral. The noise alone was astonishing; bring binoculars to see detail.

    • And a landing! S Padre is great for kids and rockets.

      For the more adventurous and/or bilingual the beaches on the Mexican side seem to have awesome views too.

    • It is one of the things I regret not ever getting to see a shuttle launch. The closest I ever got was when I flew over Florida while a shuttle was on the pad.

  • We lived ~60 miles North of the Cape when I was a young boy, and watching the Saturn V's go on the way to the moon was a forming experience.

    • I lived in Port Orange FL until i was 12, during night launches my dad would take the family to New Smyrna Beach or some where a short drive South where we watched the shuttles come up over the water somehow. I can't remember the details it was a lonnnng time ago haha. I do remember the launches sounding like popcorn popping.

      I live in Dallas now and will be turning 50 soon, i want to catch the next Starship launch live but would have to time it perfectly to get time off of work ahead of time.

    • 80 miles for me! I was a Space Shuttle era kid though. Saw the Challenger disaster during my lunchtime. And then on perpetual replay for the rest of the week on WESH/WCPX/WFTV most likely. Even still, just knowing we were launching all those people into space was awe-inspiring.

  • It's even more exciting when you realize that the last crewed mission beyond Low Earth Orbit was 1972 and each person on that spacecraft today are younger than that.

  • Its going to be a first for me and my son as well. Looking forward to tonight to make an even over it.

  • > I just missed the original Apollo flights and had assumed I would never see a moon landing in my lifetime.

    The PR Chinese might want to go for a significant landing, too, just for the prestige?

Minutes after launch they reached "ten thousand miles per hour". That's 2.78 miles per second. Nuts. No doubt the speeds go even higher later too.

I'm sure people here are already familiar with the speeds these things go, but that's the first time I've confronted a fact like that and it blew me away.

  • Escape velocity is 25,020 mph (6.95 mps), so not completely surprising.

    Note that escape velocity applies to a situation without continued propulsion and also without air resistance, but still you can imagine that the order of magnitude is similar.

    • Thank you for that precision "without continued propulsion", because when talking about rockets, physics teachers always talk about escape velocity, as if it was an absolutely necessary condition to escape earth's gravity.

      But can't you escape gravity slower, just by going higher and higher at lower speed? Like a plane? (ie not vertically, but at an angle)

      4 replies →

    • Exactly. Your rocket can escape the earth at the speed of a slow elevator if you burn the engines continuously and you can carry an infinite amount of fuel and your fuel weighs nothing.

      Since those constraints are impossible to meet in the real world, we have to get going fast enough to coast most of the trip on inertia after the fuel runs out.

  • Artemis II won't fly by the moon until Day 6, but it only took Apollo 8 to Day 4 to get to the moon. Looking at the wiki for Apollo 8, it shows the moon was 218k miles at launch while they said the moon is currently 240k, so it still looks like Apollo was moving faster than Artemis.

    • Apollo put a lot more burden on the Service Module than Artemis plans to put on the Orion. Apollo put the CSM/LM into a low lunar orbit while Artemis plans to put Orion into a high lunar orbit and make the Starship carry a lot more delta-V to land from a much higher velocity (and then accelerate back up to that velocity when coming back).

      On top of that there weren’t really solar panels in the 1960s so the Service Module had to carry tons of chemicals to produce electricity, as well as extra fuel for all of that weight. As a result it was massively overbuilt compared to anything we’d try today and even so had to take an expedited flight path to the moon of 3 days in order to conserve operational lifetime. Artemis does not have nearly as severe constraints on either the Orion or the future Starship and so can afford to take a more fuel efficient 5 day coast up to the Moon and make the design tradeoffs on Orion that that entails.

    • My understanding is Artemis II orbits earth for 23.5 hours before heading to the moon while Apollo 8 did so for under 3 hours, so that accounts for some of the difference.

  • I knew someone who knew someone, so I got to see STS-133 from the VIP area.

    Nine minutes after launch, it was in orbit.

    Nine minutes.

    • Yup, that's how long it takes. There are a bunch of competing requirements and 9 minutes to orbit is the sweet spot, you can't change it much in either direction. If you go slower you waste all of your fuel just holding yourself up against gravity ("gravity drag" which is a bit of a tongue in cheek engineering term) If you go much faster you're accelerating too hard for your passengers or your structure.

      To understand gravity drag think about the rocket firing just hard enough to hover 1 meter above the pad, you burn out all your fuel in 10 or 15 minutes and go nowhere...

      In the other direction if you want to accelerate harder you need to make your structure stronger so you need to burn more fuel per second and have to displace some fuel in exchange for more structure and you keep doing that until you're so heavy you can't produce any more acceleration and you're all engine and structure and no fuel.

  • Your comment inspired me to vibe code https://calcubest.com/other/shuttle to see how fast the space shuttle travels between world cities. Pretty darn fast.

    (also my first time trying to vibe code with Gemini as opposed to Claude and I don't know if I noticed a big difference, which probably makes sense for such a simple project).

  • A Dodge Challenger SRT Demon can also reach 10,000mph in 4 minutes if it held its 0-60 acceleration over the whole span.

    So yes, you can buy a car today that'll let you feel the G's like you're a space pilot.

    • The acceleration of a rocket is slower than a normal car at lift off. It's pulling about 1.2G, but 1G of that is fighting gravity, so effective acceleration is only 0.2G. Almost any car can do that at low speeds.

      But a car's acceleration slows almost instantly. The rocket just keeps accelerating faster as the tank empties and it gets lighter. By main engine cut off it might be pulling 5G.

    • One fact that I found unintuitive (while we're at cars doing things they can't):

      If you could drive your car straight up vertically, you'd have to cruise just for an hour or so at 100 km/h (<65 mph) until you reached space. It's not that far.

      1 reply →

  • NASA uses metric units even under Trump. So this is 16093 km/h or 4.474 km/s .

  • I was thinking the exact same thing when they announced the speed. I assume the top speed of Artemis will be at least double that too...

    • Well, notions of speed are a little tricky for spaceships, but yeah, Artemis's top speed is going to be right when it starts reentry: about 25,000 MPH.

    • It will be slower, eventually. The moon orbits at about 2300 mph, and as Artemis gets further from Earth, it will slow down to a similar speed.

It is a bit chilling to watch these astronaut profiles having just read yesterday about the heat shield issues observed on the prior mission, and that this will be the first time we can test the heat shield in the actual pressures and temperatures that it will have to endure.

Godspeed crew of Artemis II.

  • It'll probably turn out fine (in the same way that you'll probably survive one round of Russian roulette.) I am quite nervous about this though.

    • > in the same way that you'll probably survive one round of Russian roulette

      Is that with or without spinning the chamber between rounds? The odds are worse if you spin each time. They get worse as the game goes on if you don't spin.

  • I had to watch "go at throttle up" on replay on the news in 1986 for the entire year, like almost every newscast

    I was only a teenager and it burned into my brain badly

    To this day cannot watch any launch with people onboard live

    • The event itself was a few years before my time, but after reading about it and eventually watching the historical news footage, the phrase "go at throttle up" also seared itself into my brain, and ever since I flinch when I hear it.

  • Truly. I'm not sure why anyone needs to be on the rocket at all, let alone our best and brightest.

    • Because human beings are remarkably capable, especially the best and the brightest. There's a great paper called the "dispelling the myth of robotic efficiency." https://academic.oup.com/astrogeo/article-abstract/53/2/2.22... // https://lasp.colorado.edu/mop/files/2019/08/RobotMyth.pdf

      Yes, a robot car that drives on its own will be a better driver than most humans who text and drive, or have 400ms reaction times.

      But making a machine that can beat a 110ms reaction time human with 2SD+ IQ, and the ability to override the ground controllers with human curiosity is much harder. Humans have high dexterity, are extremely capable of switching roles fast, are surprisingly efficient, and force us to return back home.

      So in terms of total science return, one Apollo mission did more for lunar science and discovery than 53 years of robots on the surface and in orbit.

    • Because the goal of the program is to return humans to the moon. Artemis I was the unmanned test. This is the first manned test, and what they learn will support the subsequent missions that eventually land humans on the moon.

      This is the same way that all manned spaceflight programs are conducted. You iterate and learn a little bit at a time. "Move fast and break things" doesn't work here. :)

    • I suspect it's the optics of it.

      If you can fly people around the moon, then landing people on the moon is a more reasonable next step.

      I agree that it may not be entirely logical, but keeping public and funding opinion positive & invested _is_ important.

      edit: I thought RocketLab flew their elecron rocket around the moon a few years ago? So it's definitely doable... so again I think it's about the optics.

      1 reply →

    • It is a test of the spacecraft. They need people onboard to test all the human systems. But yes, if this was a purely scientific flyby and not part of a larger manned program, machines would do it fine.

    • Yeah. Doesn't really make sense. The entire mission could be done remotely.

      Even with a goal of eventually putting humans on the moon, it'd be better to do an automated run, measure everything in the cockpit, and put in sandbags and/or something to consume O2 to make sure the CO2 scrubbers are working correctly. It's maybe cruel, but a few dogs would work fine for that sort of thing. A flame would be better, but it's pretty dangerous.

      The first mission in decades doesn't need to have humans in it.

  • I mean, that's how these heat shields work. They aren't reusable, you can't test them and then use them again. Or do you mean the design? We already did Artemis I.

    • I mean the design.

      They've changed the AVCOAT to be less permeable and altered the re-entry profile.

      One of the findings of Artemis I is that lack of permeability led to trapped gas pockets which expanded and blew out pieces of heat shield. The reason for the change to be less permeable is to make it easier to perform ultrasonic testing, not to improve performance.

      They altered the re-entry profile on the theory that the skip period contributed to spalling, but Charles Camarda disagrees in this doc: https://docs.google.com/document/d/1ddi792xdfNXcBwF8qpDUxmZz...

      > Another chart which the Artemis Tiger Team did not intend to show on Jan. 8th, was the figure showing the spallation events as a function of time during the skip entry heating profiles (Figure 6.0-4 of NESC Report TI-23-0189 Vol. 1). In this figure, it was quite clear that the Program narrative they were feeding to the press, that it was the dwell time during the skip which allowed the gases generated to build up and cause the delta pressures which caused most of the spallation was, again, patently false. In fact, during the first heat pulse (t ≈ 0 to 240 sec), approximately 40-45% of all the medium to large chunks of ablator spalled off the Artemis I heatshield.

      > Hence, varying the trajectory would do little to prevent spallation during Artemis II. I was never shown the new, modified trajectory at the Jan. 8th meeting.

      1 reply →

    • We already did Artemis I and the heat shield lost a lot more material than it was supposed to on that flight. "Specifically, portions of the char layer wore away differently than NASA engineers predicted, cracking and breaking off the spacecraft in fragments that created a trail of debris rather than melting away as designed. The unexpected behavior of the Avcoat creates a risk that the heat shield may not sufficiently protect the capsule’s systems and crew from the extreme heat of reentry on future missions."

      Fixes have been made to the design, but they haven't been tested in flight.

After spending years as a kid seeing footage of these things on TV outside living outside of America, I finally got to see it live!

Brought my camera and got a few good pics too! Very invested in this entire mission!

Someone behind me kept whisper crying "That's it! Go baby, go baby go" like it was his child and was encouraging them on. Very emotional, loved it.

Also when that engine sparked it really hit me just how many hours of deep thought and technical innovation goes not only into getting us as humanity to that point, but also the crews at NASA planning, building and executing these missions

  • I watched the livestream and at one point (several points, i guess) they cut to the crowd watching and the thing that stood out the most to me was that every single person was staring at their phone pointed at the rocket. Nevermind the fact that better quality videos will live forever on the internet available to anyone who wants to watch them, but I cannot fathom having that opportunity and not watching it with my own eyes with my full attention.

Fingers crossed that this https://idlewords.com/2026/03/artemis_ii_is_not_safe_to_fly.... doesn't have any effect.

  • Of course it's not "safe"! We put a ton of explosives into a huge can, put a small can with humans on top of it, set it on fire and try to control what happens and get the humans into space, and then we try to drop the same can from the space, while it's traveling at miles per second, and land it on the ground. It's not "safe" and won't likely be "safe" in our lifetimes, there's always big risk, that's why astronauts get so much respect - they take a lot of risks. These risks become smaller with time, but still they are quite serious. And of course anything that reduces risks - while not disabling the whole program - is good, but I don't think "safe" is the word that is justified when talking about those things.

    • What he means and you're interpreting a bit too literally is that this [heatshield] is one subsystem where the risks are not well understood or quantified as, say, the propulsion system, for which we have a lot more experience and flight heritage.

  • There is a LOC (Loss of Crew) number that is typically calculated for these missions. I'm curious what that is? Early Apollo missions were on the order of 4%.

    • Before the Apollo launch, von Braun was asked what the reliability of the rocket was. He asked 6 of his lieutenants if it was ready to fly. Each replied "nein". Von Braun reported that it had six nines of reliability.

    • In 2014 an independent safety panel estimated 1:75, but I think it's slightly better now. The shuttle program officially had a limit of 1:90 but in practice achieved 1:67.

The politicization of everything and constant doomerish on here sure has echoes of early 2000s Slashdot. That's not a compliment. Reading the comments here is actually depressing. Human progress is never all at once, we can't even celebrate this triumph? Life is almost never "one or the other," the program could be scrapped to a junk yard and that wouldn't solve global hunger or global conflicts. Setting human eyes forward is good.

  • I pray to never reach a point of cynicism where my response to watching humans leave the planet on a rocket is immediately "meh, whatever, here's my political complaint of the week"

    Global hunger's a great example. When we last left the moon (1972) 35% of the global population was undernourished. Today it's ~8%. Optimism is a choice, and generally a more rational one. That doesn't mean we don't have real issues.

  • In many ways I agree with you, but you have to acknowledge that things change when the _benefits_ of going forwards are funnelled to fewer and fewer people. That is what colors people’s view of what is happening in the way you are seeing.

watched this with teary eyes. it truly shows what we can do when we come together and challenge ourselves for the greater good of humanity.

  • A real bright spot compared to lately. The messages of positivity and comradery in the live stream were a nice contrast

    (That being said, I can't believe they cut to people on the ground during SRB separation!)

    edit: here's better footage from Everyday Astronaut: https://www.youtube.com/watch?v=QOsSRRBMNoc&t=24512s

    • I completely agree on all points.

      On your parenthetical point, I also agree: some really weird camera selections, and frustrating dropouts, during the crucial moments of the launch.

      Nevertheless, a real triumph, and I particularly enjoyed the "full send" remark from (I think) the commander. I also really enjoy the fact that the livestream is relatively light on commentary and that most of what you hear is from mission control and the crew.

    • I was cussing at the director of that video stream during that. It was a totally useless shot as well that they lingered on that already had me bothered, and then to cut back to the SRBs fully separated had me in full contempt. Nothing to see here and everything to miss. It's like music videos showing the singer doing nothing while the guitarist is shredding a solo. Like WTF. You have one job, and you totally botched the hell out of it. You get what you pay for I guess. Lowest bidding contractor???

    • I couldn’t believe it when that happened. Intern at the controls maybe.

    • It was probably deemed a relatively high-risk moment which they did not want to broadcast in case of failure like it was when the Challenger mission exploded.

    • I tried watching his video and he is insufferable. I wish him well, glad he's enthusiastic, but this isn't a CS:GO final, it's one of the most widely watched rocket launches in 50 years. You do not need to be screaming at me in the final ten seconds about how the core stage is lit, over the actual professional saying core stage lit. You do not need to repeat to me that this is a momentous rocket launch twice at T-30.

      As someone who has watched launches before, it is so much better when the broadcasters keep it mostly together, and know when to be silent for periods of time. He does not know how to do that.

    • Agreed! I yelled at the screen when I saw that they cut away.

      I also loved the shot of stage separation, but they cut away from that way too soon also!

  • Same. I watched Apollo 11 launch in 1969 when I was four. Watched on our neighbor's TV. We didn't have one.

    Imagine what we could accomplish if we didn't suck.

    • I’m not American. The Artemis launch feels to me like a beacon that the America the rest of us looked up to isn’t gone.

    • sending people to the moon was never useful. We can get more done with robots, both cheaper and safer. There are plenty of more useful things we can do instead.

      okay what is more useful is a matter of opinion. you can disagree, but I stand by it

  • I tuned in for 60 seconds, the presenter got everything wrong, and I just tuned out until liftoff.

    She called the top of the ET (well, it's no longer an ET, but it's the stage that was the STS ET) the "upper stage". She said that the propellents are stored at thousands of degrees below zero. And so on. This is a NASA presenter?

      To be fair to her, she seemed to explicitly refer to what sits on top of the core stage, it just wasn't in the diagram she was gesturing to the top of at the time.

      To be fair to you, I think the cryogenic comment was worse and she actually said "thousands of degrees below Fahrenheit".

      The problem is they're trying to run hours of programming leading up to this launch for some reason, but aren't willing to force the experts to come in to do the commentary. They should have given her a script.

    • You are not the target audience for this sort of presentation. Media directed at the laity is more about being directionally than quantifiably correct, and is full of metaphor and embellishment to capture the imagination rather than communicate something with precision.

      People who want the actual details and numbers will read.

    • i'm sure the whole talk track was piped through an AI for clarity and excitement and the presenters were told to read the script.

  • I feel like they really fumbled the video feeds, it was a mess. Rapid shifting of camera angles as it left the pad, black video, switching to a grainy video of the crowd during booster separation, and a hasty switch back well after they separated.

    Come on guys. You're going to the moon. You couldn't plan the launch camera / video feed better? This is how the world sees it, gets excited about it.

    • Quality just looked so poor too it honestly felt 90s quality on some of the feeds, will be criminal if they don’t sort their cameras out before the moon landing

"We have a beautiful moon rise, we're heading right at it" got me a little choked up. Here's to the ever unfolding adventure of mankind.

  • Orbiter, the space simulation predecessor to KSP, has exactly such a mission where you see the moon in front of you as you ascent into the sky.

Found a stream on YouTube earlier (which presumably wasn't an official one because it disappeared 15 minutes later after a claim by "FUBO TV") and it had a poll attached: "Will the Artemis astronauts land on the moon?"

40% of people had voted yes. Which is somewhat worrying given the mission plan and hardware.

Regardless of whether this particular mission is perfectly planned, this is precisely the kind of thing that will help humanity outgrow the dark age of war, inequality and climate mismanagement.

It is a noble endeavor - science, engineering and peaceful exploration hold the keys to our survival and prosperity.

It is also important psychologically to our survival - a reminder there is a bigger pie, that we can solve hard problems, that progress can be made, that competence and education counts, as does courage, and that we can work together for a common cause.

This is the best of America, and for a while we can be proud of the human race.

  • I think these space projects are great, can create much good will, and give people dangerous things to do that are worth risking the danger for. But war, inequality, and climate mismanagement are political problems that are not going to be solved (if they need to be solved) by science and engineering (the first two at least).

    • If AGI stages a hostile takeover of all the governments of the world would that count as a technological solution to war and inequality?

      For that matter I suppose the terminator timeline also counts. Can't have war and inequality if you don't have humans.

  • I hope it does. But every day that goes by I feel that the future is just going to be like what's shown in the expanse series

    • My personal take for a long time has been that the primary driver of most war today is boredom. War today is undertaken for entertainment. It's a special kind of entertainment that taps into deep brain stem circuits and provides a false but deeply resonating sense of purpose and meaning. When you hear that "people don't have a sense of meaning," it means their brain stem is not feeling the tribal loyalty emotions connected to warfare.

      It would be cheaper to solve resource shortages in almost any other way. I don't really buy that explanation, at least for most wars. I think most wars today have roots that are far less rational.

      Note that this applies IMO to all participants on all sides insofar as they had any role in starting or sustaining the war.

    • The expanse future isn't that bad - even at the start of the series we've already made it to the asteroid belt and Jupiter moons, and the civilization consists of several sovereign self-governed entities with individual entrepreneurship and private enterprise allowed. It means we didn't annihilate ourself in a nuclear war, nor our civilization collapsed into allways-fully-connected ant colony (or one global fascist/communist/religious regime).

  • > this is precisely the kind of thing that will help humanity outgrow the dark age of war

    Just a reminder that even the Utopia of the 23rd century and beyond envisioned by Gene Roddenberry for Star Trek - the Federation and Starfleet are still at their core military institutions. Even war was very much still a thing in his utopic vision, despite the fact that scarcity basically no longer exists so what hell was everyone fighting over anyway?

    Starfleet is only a few steps removed from the regime in Heinlen’s Starship Troopers. At least Heinlen didn’t pretend that they were enlightened post-imperialists. He was honest about what it was.

    • Wasn't war on Earth not the issue but war with other species in the galaxy the issue? Sure, there were some sympathizers trying to sabotage peace, but that's because they wanted to continue warring.

  • > this is precisely the kind of thing that will help humanity outgrow the dark age of war, inequality and climate mismanagement.

    Is that irony or plain naiveness? historically and technically, conquest of space is inseparable from warfare. As for climate change, one can argue that technology is one of the primary driver: aviation alone is estimated to 4% of global temperature rise.

    • Energy use is the driver. Fossil fuels happen to be cheap. It's effectively a coincidence, nothing inherent to technological progress itself except insofar as something like aviation would never have been a commercial success without an exceedingly cheap, dense, and portable method of energy storage. Solar-syngas and solar-battery would have eventually gotten there but we'd all have been taking trains and ships for the past 80 years while riding electrified public transit.

    No one cares about space any more and no one engaging in space travel is doing so for science anymore. Those days, if they ever really existed, are over. NASA has been cleansed and gutted and purged of wrongthink and now only exists to further the cause of American propaganda and be parasitized by SpaceX and intelligence agencies.

    More likely, it is precisely the kind of thing that will be managed specifically to keep people distracted, so that the people who have a near term benefit from the dark age of war, inequality, and climate mismanagement can continue realizing that benefit without interruption by people taking action right up until there is no one left to distract or benefit.

  • The engineering was done in the 70's and 80's. This rocket is built out of leftover shuttle hardware.

    The exploration in this mission was done 50 years ago.

    I fail to see how this mission is noble. It's biggest accomplishment is keeping the NASA beurocratic apparatus in tact.

    This spectacle of a mission is precisely the kind of distraction which enables complacency and allows the "dark age of war" to remain dark.

The SpaceX cameras of live launches are way better. This NASA stream is mostly all computer generated art after the initial pad launch. Hardly any live space feeds from the ship.

Does anyone know of a good status tracker for the mission? I'm watching the official feed on Youtube and it's great for commentary but I'd love a live Kerbal-style UI I could poke around.

The entire league could fund the whole Artemis program nearly twice. Hosting the Olympics is worth about 3-10 launches.

      Like sports, the objective is ultimately useless except as a showcase of what humanity has to offer, and people like to see that.

    • This argument comes up a lot, about whether a space program is “worth it” in some sense. One problem I’ve found is that these discussions often treat this in the abstract. And then we get into the nature of human endeavor, the economic benefits of that R&D, etc.

      Let’s talk about this in terms of practicalities. The NASA budget for 2026, per Wikipedia, is $24.4B. I often find it hard to really reason about the size of federal budgets, and the impact on tax payers, but I have a thought experiment that I think helps put it into perspective. Suppose we decided to pay for the NASA budget with a new tax, just for funding NASA. And we did that in the simplest (and most unfair) possible way: a flat rate. Every working adult in the US has to pay some fixed monthly rate (so excluding children and retirees). Again, per Wikipedia, that’s around 170M people. Take the NASA budget, divide by 170M, and you get … $11.96/month.

      Obviously, there’s lots of flaws in this. That’s not we pay for NASA, we have income tax as a percentage with different tax brackets. But it is a helpful way to frame how much a country is spending, normalized by population. And I think it puts a lot of things in perspective. $11.96/month is comparable to a streaming service. And we talk a lot about whether NASAs budget is better used for other purposes, but we don’t do the same thing for a streaming service.

      Hell, look at US consumer spending: https://www.bls.gov/news.release/cesan.nr0.htm (note that that spending is in dollars per “consumer unit,” which is I think is equivalent to an adult US worker, but there might be some caveats). Based on that, the average US consumer spends around $26.17/month on “tobacco products and smoking supplies”. I just feel it’s a little silly to worry about the NASA budget when the US consumer spends twice that on what is objectively a luxury good. At least NASA won’t give you cancer.

    • > My personal perspective is that the resources are better used for other purposes, but it's possible that I just haven't encountered some compelling reason yet.

      Well, people are often obsessed with rationality, and seek reasons to do something, but there is one reason that works almost for anything: just because. If we want to go forward, we'd better try a lot of things, including those that do not look very promising. We don't know the future, the only way to uncover it is to try. Did you hear about gradient descent? It is an algo for finding local maxima and to do its work it needs to calculate partial derivatives to choose where to go next. In reality doing things and measuring things are sometimes indistinguishable. So society would better try to move in all directions at once.

      A lot of people believe that to fly to the Moon is a good idea. Maybe they believe it due to emotional reasons, but it is good enough for me, because it allows to concentrate enough resources to do it.

      > the resources are better used for other purposes

    • I always found this framing interesting.

      Sure, if we lived in a purely utilitarian world, there's some merit to the argument that space exploration is a waste of resources that could be more efficiently used elsewhere. We don't live in a utilitarian world though, and instead we have the same (and in reality much, much larger) amounts of money and resources that get spent on this moon mission being spent instead on bombing the Middle East with nothing to show for it other than an impending global economic crisis.

      Could the money spent on Artemis be spent somewhere better? Probably, but how about we start with not burning through 38 billion (and rising!) on a farcical boondoggle of a military operation whose only effects so far are increases in the cost of literally everything? The first WEEK of the war cost 11 billion[1], but when it comes to NASA we're suddenly penny-pinching?

      And that's talking pure monetary expenditure, without even going into the human lives lost, the lessening of sanctions on Russia (which will in turn cause even more suffering in Ukraine), or the halting of trade through the Suez, etc. etc. etc.

      From where I'm standing, even if Artemis turns out to be a complete and utter disaster with not a single benefit of any kind coming out of it, the worst possible case scenario is a few astronauts die and we wasted a few billion (and I guess NASA gets shut down). That's of course us working under the assumption that there won't be a single novel scientific discovery of any kind, or that we will learn absolutely nothing from these missions.

      The current unjustified war the US is waging on the other hand has already killed thousands of people, and will continue harming every single person on this earth through the economic fallout alone. The US is quite literally setting money on fire with every single bomb they drop over Iran. And the true worst case scenario that I can easily imagine happening is nukes getting dropped and all the consequences that follow from that.

But the notion that any loss of life is intolerable is (a) unsustainably expensive and (b) not a view shared by the lives actually at risk.

    For what it’s worth, I watched today’s Artemis II launch with them. While proud of the mission, they’re likely in your “Doomer” category after a year being devastated and demoralized by having their science budgets slashed, grants/projects cancelled, having been forced to fire good contractors of 10+ years and then watching some of the most knowledgeable/skilled folks take early retirement. Don’t let the awe or Artemis fool you — NASA, especially when it comes to science, has been gutted and functionally degraded. For what it’s worth, they’re not focused on earth/climate science.

    • Yep, I work with them every day, since I am myself a NASA contractor. I'm curious what you think the major distinction is between a contractor and a civil servant in the first place. I work directly as part of a division (used to be "on site" before 2020, but now I'm remote so that doesn't quite fit) doing 80% the same job as any of my civil servant colleagues.

      I mean, newly shaped and partly reformulated.

      Avcoat was “originally created…for the Apollo program” [1]. (“A reformulated version was used for the initial Orion heat shield and later for a redesigned Orion heat shield.”) The new things are Orion’s size and weight and the size of the tiles. All of which has precedented flight in Artemis I.

      At the end of the day, I’m going to trust the astronauts. This issue was openly discussed, despite NASA’s original—and fair to criticize—instinct to cover it up. While any manned reëntry is a nail biter, I don’t think this one is especially so.

  • I certainly hope the mission goes as planned but it does feel like SLS is the wrong approach in the time of reusable rockets, even if this specific mission profile would probably have demanded the booster be expendable. Using the Shuttle main engines - designed and made to be 'refurbishable' rather than 'reusable' but still dumped into the ocean after each mission - and the SRBs (solid boosters) still gives the impression of the booster design being dictated (at least in part) to accommodate the needs of former Shuttle contractors. If either Starship+Superheavy or some other fully reusable heavy left vehicle comes on-line it will be hard for NASA to justify spending billions of $ on, well, a flying pork barrel. Sure, it has been proven time and time again that canned pigs can in fact fly but that does not make them the go-to transport.

The camera work was just terrible. They really need to learn from SpaceX how to do this right. Minus the obnoxious cheering.

SpaceX does these beautiful drone shots and live telemetry so well. Considering that each SLS launch costs in the billions it would be nice to do a little better on production

I felt the commentary during the launch also wasn't good. And I am not too interested in hearing from some Hollywood people before the launch

  • I love listening to the cheering because it really drives home what an accomplishment it is for the people who work on it.

    Starlink launches don't get the cheering, so it's not like it's a laugh track.

  • I thought the same thing - hopefully by the time Artemis III launches they'll remember the gaps and blank screens from this launch. Even the live telemetry model at the core stage separation seemed to not match what the on-board cameras showed. Artemis I's camera work was better. Why???

I'm having trouble finding a simple tracker of whereabouts the craft is at in terms of the path to the moon? Might just be me but the fancy 3-d rendering thing on the NASA page just shows me a close-up of the craft and not much else?

Longest trip since 1972.

I hope we as humanity never stop again.

Good luck!

Wish them all the best and safe travels. I’ll be tuning in as you never know when the next crewed mission will be, probably not another 50 years if advancements in space travel happen.

Praying for these astronauts to have a safe return. The heat shield stuff has me really rattled. These folks are really brave to go through with this.

There are tons of comments here that say, "this could have been a robot." And no, it really couldn't have.

The best of humanity is remarkably capable as compared to the best physical machines / robots. There's a great paper called the "dispelling the myth of robotic efficiency." https://academic.oup.com/astrogeo/article-abstract/53/2/2.22... // https://lasp.colorado.edu/mop/files/2019/08/RobotMyth.pdf

Yes, a robot car that drives on its own will be a better driver than most humans who text and drive, or have 400ms reaction times.

But making a machine that can beat a 110ms reaction time human with 2SD+ IQ – and the ability to override the ground controllers with human curiosity – for exploration is much harder. Healthy, smart humans have high dexterity, are extremely capable of switching roles fast, are surprisingly efficient, and force us to return back home.

So in terms of total science return, one Apollo mission did more for lunar science and discovery than 53 years of robots on the surface and in orbit.

  • They are not going to land on the Moon! They are just going to sit in a can for two weeks and take photos. (OK. Tthe can is on top of a lot of burning explosive material and if they don't aim correctly they will get in a weird trajectory that will kill them. Not for the faint of heart.)

    I'm not sure if they can override the commands send from Earth, but turning on and off the engines like in the Apollo XIII movie is like 100 times less accurate than the automatic orders. It's not 1969, now computer can play chess and aim to go around the Moon better than us.

    Also, there is still Artemis III to test the live support equipment with humans inside, before Artemis IV that is spouse to attempt landing on the Moon.

I really hope the report from a few days ago about the heatshield not sustaining earth reentry does not turn out to be true.

  • I desperately hope so too. It will be absolutely terrible if there were to be an issue, and moreso if people can say “We knew about it beforehand but still went ahead”.

I'd like to see views of the moon and the earth from the spaceship on every hour. Is there any link for that?

It's good to see NASA finally do something beyond navel gazing. Nonetheless, calling this flight historic is a stretch. Other than flying a few miles further than Apollo 13, it will actually accomplish less than Apollo 8 did 57 years ago.

  • What did Apollo 8 accomplish more than Artemis 2?

    • Apollo 8 actually went into orbit around the moon. This flight is more similar to Apollo 13, hopefully without the life threatening problems. The risk on this flight is far less than on Apollo 8 obviously. Still, it's more than time for the US to step up and have an actual space program. The shuttle program and ISS fall far short of the trajectory of the US space program at the end of 1972.

  • what about the fact that it is a joint effort between different agencies?

    • Doesn't mean a thing in the grand scheme of things. Nor does having a woman, a minority, and a Canadian. Those are irrelevant. It makes some people feel good and others virtuous, but it doesn't further the mission one iota. Show me technical accomplishments, regardless of the crew composition and the agencies involved. The crew can all be women or minorities, I don't care. I'm looking for progress and accomplishments, not virtue signaling.

Just listened on the radio driving the kids to swim class! I'm curious, does anyone think the show For All Mankind provided any peer pressure or influence to help propel NASA to this moment?

  • It’s a fun idea to consider, but I suspect the true push is due to how capable China is proving to be in spaceflight. They’ve got plans for a manned mission to the moon and are eyeing the same craters at the Lunar South Pole as we are.

    While the outer space treaty forbids claiming territory in space, it doesn’t forbid building a base and putting a “Keep Out” sign on the airlock.

  • As a huge fan of Ron D. Moore’s shows, and especially For All Mankind, I don’t see how it could possibly have (or have had) any meaningful impact on NASA or NASA-adjacent efforts. Especially Artemis.

Is anybody aware of audio-only coverage of this mission? I'd have loved to just tuned into most of the launch like radio, rather than having my unwatched youtube running.

This is the first live launch I've seen on TV (well, YouTube in this case) since the Challenger disaster. Was a nice relief to see this one go so smoothly.

  • You never watched any of the SpaceX launches? The first landing attempts? The massive explosions or 'RUD' - rapid unscheduled disassembly - events? The epic launch and synchronous landing of the twin Falcon Heavy side boosters?

    Why not? Maybe you're not interested in space launches, in that case I understand. Otherwise I wonder why you did not follow SpaceX in its path to reusable rocketry.

    • OK, the down-votes were the answer I more or less expected. Sad, really. Sad to see how some of the supposedly intelligent denizens of this site are incapable of separating the aspirational from the personal, how they can not marvel at the achievements of a company like SpaceX only because they are supposed to hate everything the leader of that company does.

      Also sad to see that the down-voters - or single down-voter with a few accounts - again down-voted all my recent - totally unrelated - posts. Grow up, man-child, it is high time.

If the crew were to be lost into deep space or something, is there a protocol for self euthanization?

  • They will be in a free return orbit so that can’t happen - just other bad things.

    • What’s the margin of error on a free return orbit burn though? Isn’t there a scenario of being pointed slightly in the wrong direction or burning for too long throwing them off?

I'm watching it rapt, but also wondering which KIND of leaky will result in a scrub..

  • Can't understand why there doesn't seem to be much wider excitement at all, around "our Apollo 8", that I've been waiting decades for (late 40s here).

    Apparently here in the UK our schools are hardly even hyping it.

And NASA proves that it's still got game!

  • Really it’s all the primes and sub contractors. NASA is more like a management layer. The difference between this and what commercial space companies do comes down to who’s paying and what’s the penalty for poor performance. Not much motivation to get things done in a timely manner with cost-plus programs.

I'm just SO HAPPY we can talk about something that doesn't involve the Iran war, ICE etc. This is a really historic moment, I hope that the current and future administrations continue investing in space exploration. I've waited my whole life for this as the entire "action" happened before I was born. Hubble/James Webb/ISS are cool but Artemis is something else!

  • >we can talk about something that doesn't involve the Iran war, ICE etc.

    And yet, you did bring them up.

  • ... federalized voting, birthright citizenship... it is amazing how space exploration can be a unifying moment of positivity.

I get that not everyone, even on HN, thinks crewed-spaceflight is worth doing. And I certainly get that launching people to the moon doesn't makes up for the latest crap thing Trump is doing to the world.

But I really think that space exploration could be the thing that unites everyone, and the more unified we are--the more we feel like we have a common purpose--the easier it will be to solve our other problems.

I for one pledge to support space exploration (crewed or uncrewed) regardless of who is running the government. I will cheer Artemis II even though I voted against Trump. I will cheer if/when China sends people to the moon. I will even cheer if Russia does something cool in space.

Oh hell... Thanks for this reminder, I have almost forgot about it with all the problems I'm trying to solve now.

Somebody needs to say that:

What was the AI usage in this endeavour?

Zero, huh?

It is very disconcerting to see so many completely disregarding incredible technological innovation because other problems exist, especially on HN.

If we were not allowed to progress technology until everybody is 100% free of suffering, we'd never be able to create technological that may potentially lead to the alleviation of suffering. It all feels very crabs in a bucket - "I don't feel happy so nobody else should, and nothing should happen unless it is things that directly, immediately do things I want and solve problems I care about."

  • There is no technological innovation in the Artemis stack.

    Three of the main engines are refurbished Shuttle engines. The fourth is a clone that cost more than the entire SpaceX Starship stack.

    The boosters are derived from the Shuttle SRBs.

    It's a late-60s technology rocket stack with a 2000s-era flight computer.

    It's such a travesty.

    • Its true that innovation isn't clearly shown in this mission; we also haven't flown humans out that far in more than 50 years either and while we have memories of it, our ability to even execute something like this must be built again. I'd rather see us doing this and 'pick up from where we were last time', than giving up on it or just using a stack that's not currently set to do this.

      What Artemis is doing is not impeding innovation: its building our muscle back to work on such things; the discipline, rigor, scale, and attitude needed to execute such missions is unimaginable and orthogonal to the technical innovation and stack used. I also believe that its completely fine to use a 2000s-era flight computer, if that suffices for this purpose. Somehow, for such critical missions, my mental model is to use at least 10 year old technology that has stood the test of time, before going into space. If there's a need for the latest technology - then yes, it should be leveraged.

    • > is no technological innovation in the Artemis stack

      Scaling is still engineering.

      And the environmental control system, laser-optical communication systems and block-construction heat shields are new. For Artemis III, in-obit propellant transfer will be new and transformational.

    • It's silly to say there's no innovation here. These aren't legos that you just snap together. I'm sure there are innovations up and down the whole thing, using the old technology they have easily available to them.

      No, it's not the most modern Rocket Lab or SpaceX project but they have immense drag on their process that those companies don't have and they still got the dang thing up and headed toward the moon.

    • It's not about the Orion unit specifically but the fact that this is happening in the first place. This is simply a precursor to future missions and the construction of the Artemis Base Camp.

    • This read like one of those "I could've done this in a weekend" replies to app launches.

    • IIRC there are some hydrogen powered APUs on the SLS core stage, replacing the Hydrazine powered ones used on Shuttle (both on orbiter & SRBs). The solar panel control on the Orion also seems coo and useful, not to mention having cameras on the arrays for self-inspections.

      I am sure there are more subtle innovations like this that would hopefully be useful on more sensible rockets and space vehicles in the future. :)

    • While that might be true, it is on course to the moon now. Starship hasn't really done anything close. So while cheaper might be on the way, it doesn't exist now. When Starship can do now, we can talk about if the Shuttle Leftover System is ready to be retired

    • I believe the fourth is actually built from left over STS engine parts and they haven’t gotten to the clones yet.

    • Well what are they suppose to do other than continue where they left it? As far I understand purpose of Artemis mission it is to build a pernamently occupied base on the moon not to build better and better rockets now. I mean, it's not the best solution but it is proven to work and they perceive it as enough for now. I think it's very similar to some critical systems still running code written in cobol sixty years ago.

    • It's in orbit. I for one love the fact they recycled some well-designed engines and made this mission a success (so far).

    • The Artemis was a pork barrel project to feed federal tax money to all the states that had huge space shuttle contracts.

      That and NASA is pathologically terrified of anything resembling innovation.

    • So, are you suggesting we should not misunderstand “just business” as “glorious human achievement”?

    • Yeah, fuck the engineers who worked full time and ran many simulations tirelessly and worked out the best stack for this mission, right?

      Most of the combustion engines in your car are still from designs late 60s - 80s (Eg. Renault). Does that mean it's a travesty too?

      Let me guess, a bunch of dudes sitting in SF in a garage could have made a better rocket that runs on ReactJS, right? Because NASA BAD.

      Give me a break.

  • This is such a strawman argument because nobody expects nobody expects all wealth to be redistributed absolutely equally. What many of us would like however is a sufficient baseline.

    I've recently seen a seris of Tiktoks from a 50 year old woman who lives in rural China on ~$1/day. She works in a shoe factory and makes ~$11/day. Her husband is a truck driver. Thing is, she has a house, a phone, an electric scooter, enough to eat, electricity and overall all her basic needs are met.

    That's the baseline for modern China.

    In the US, you'd end up homeless, eventually lose your car, find it impossible to keep your car, probably end up self-medicating with drugs, get harassed by police and ultimately your status will be criminalized and you'll end up being convict labor.

    I don't need Jeff Bezos to have the same amount of money as everyone else but I do want, in the wealthiest country on Earth in particular, everyone to have secure housing health insurance, food, clothing and utilities.

    There are other reasons too to criticize the SLS program: it's incredibly wasteful and is just another welfare program for defense contractors. The Artemis/SLS programs have cost ~$100 billion in the last 2 decades. That's staggeringly inefficient. Likewise, each Artemis mission costs ~$4 billion. That's ridiculous.

    I, for one, would be much happier seeing these Moon missions if it wasn't such a giant scam to steal $100 billion from the government coffers.

    • Well said. I find it interesting that a single proton-m total cost per launch is about 70 million. Of course its lift capacity is much smaller, but if the 4 billion figure is correct, it does seem like a ridiculous amount. But then again things are no different from the defense expenses.

  • I agree entirely. HN tends to be incredibly nitpicky and dystopian. I think it's because so many HNers work in dystopian software-only companies, not doing much in the physical world, away from the algorithms.

    Incredible technological innovation is on the horizon. That's why we are not doomed this century. We can make it.

    *hits 'reply', knowing there will be nitpicky comments because of course on HN these days, no positive point shall be left standing.

  • How dare we want to fix the existential threats on the planet before we spend billions on a publicity stunt.

    No, there's no possible way we "save humanity" with space exploration. The whole "eggs in more than one basket" thing is insane.

    The resources required to establish a colony, get it self-sufficient, then able to grow, and then put enough people on it will take half a century and the planet is burning up today.

    • Do you think that had this not launched that it would have been spent on something else that would have "saved humanity" better?

      US spends 4x as much on just nuclear bombs as the NASA budget for some perspective. Nuclear bombs are only 10% of the military budget, and as big as the military spending is, all of that is still only 15% of the federal budget.

      It seems a bit ridiculous to be thinking NASA spending is in any way meaningfully holding us back from whatever "save humanity" spending we could be doing.

    • why pick on space exploration which has such a small budget and provides with a lot of hard science, technology, boosts the economy, etc and not pick on many other things we do that make no sense? why not pick on the military? or fossil fuel subsidies? or the entertainment/sports industry? or ads? why not pick on bureaucracy or war or billionaires? ... all of those have way bigger budgets and ain't fixing any "existential threats", arguably making them worse

      It's so easy to pick on the few remaining industries and science that invest on a future that is not the next quarter and doesn't just make the same people richer. Make no mistake, the little money spent on space exploration (or science in general) is not what's causing or keeping us from solving existential threats.

Waiting to see what happens to the heat shield on reentry...

  • > the agency said it was confident that a change to the re-entry trajectory would be more than adequate to offset any spalling issues. Somewhat confusingly, they also announced their intention to switch to a new heat shield design, starting with Artemis III.

    It's fine to be concerned, but this kind of take is why public agencies are damned no matter what they do. In the private sector, operating with the suboptimal resources you have while working on a better iteration is standard practice, even in industrial settings. But when you're a public organization, if anyone can find anything that is less than 100% optimal, the same people who complain about how slow the public sector is will complain that you're cutting corners, or that you're inept.

  • > the agency said it was confident that a change to the re-entry trajectory would be more than adequate to offset any spalling issues. Somewhat confusingly, they also announced their intention to switch to a new heat shield design, starting with Artemis III.

    This is not confusing in the least. Engineers don't talk about safety in binary terms. It's not "safe" vs. "not safe". Instead, it's all about the probability of a bad outcome. At NASA, they compute the probability of Loss of Crew (LoC) and the probability of Loss of Mission (LoM).

    For Artemis II, a change to the re-entry trajectory brings the LoC/LoM back to an acceptable level. For Artemis III, which a new shield design, they can get to the same LoC/LoM with a different trajectory (which gives them other benefits).

    Stop thinking in terms binary terms. Everything is a probability.

  • Yeah the whole production of the launch broadcast was pretty lousy compared to what SpaceX does. Their mission tracker website isn't working either. Considering that this broadcast and the other public affairs stuff is essentially the deliverable of the mission, it's not too great.

  • I don't know why you're getting downvoted. The camera work was atrocious.

    It's not just frilly video, it's how the world sees it, emotionally connects to it, and grows up loving it, and wanting to support more.

    We had black screens as it left the pad, they didn't know what camera to switch to and kept changing feeds every 2-3 seconds, they switched to a grainy feed of the crowd just looking up while booster separation happened, so we missed that, and hastily switched back after they separated.

    All the prep and they couldn't come up with a media plan? Maybe it was technical problems and their camera indexing was off or something.

    • They had the longest reaction shot of some people filming it with their phones (maybe they got a good shot) and when they switched back to after the booster separation I said at the time, “that would have been cool to see.”

    • Even in the 1960s with 1960s technology they made better broadcast video of the Apollo launches than this.

    • I suspect that they might have switched away from the booster separation on purpose. That's probably a risky moment of the launch, and they may have wanted to avoid televising a disaster like in the Challenger launch.

      Aside from that, agreed that the camera work was awful.

  • It's hard enough to train a camera on race cars speeding by at 250+ kilometers an hour.

    • But it isn't speeding by, it's heading away following a closely predetermined trajectory. A better analogy would be filming a high-altitude aircraft flying away from you, using a gear-driven tripod mount.

    • It is hard, but Everyday Astronaut had a manually-operated camera with a 2,000mm lens that captured everything from engine start all the way through a reasonably-clear view of SRB separation.

    The entire world's problems is too much for one human.

  • Well. You are getting down voted but here I am in later stages in life watching this Moon launch, and unlike other times in past, I didn’t feel any inspiration.

    Honestly, it’s a waste of money. That’s my final answer, there’s kids that need food. I am no longer inspired by this stuff.

    I’ve seen enough advanced technology for many lifetimes, we need something else as a species (more of that humanity thing).

    • I understand your side to some extent. It helped watching my 11yo watch the launch - for him it's more meaningful, more imminent than it can be for a jaded person like myself.

      I don't think it's mutually exclusive with food aid, though. If anything, it's taking money that probably would have gone into bombs and aeroplanes instead if we didn't have a space program. Honestly, it feels like we could redirect the entire military-industrial complex into space travel... retain the same pork spending but use it for rockets that aren't designed to land on our neighbours. Nice compromise.

      I’m sure folks said the same before the Green Revolution. “Plants have always grown one way!”

  • Yeah. I've been excited about Artemis since the very start and have been following everything very closely. And of course I was excited about this launch.

    But I'm gonna be honest, I'm not feeling any positive feelings here in the moment. It's an insane achievement, but it kind of means nothing for humanity. A nation's representatives literally popping champagne because they passed a law that will allow them to hang their hostages, just a day ago.

    The engineering advancements that have been made during Artemis will be used to kill children tomorrow and the day after that. I have spent a large amount of my life in pursuit of knowledge about space exploration. I would give up any chance of ever knowing anything about space for the safety of those children. None of this hubristic rocket crap really matters in the end.

    And I know, NASA and the military have always been intertwined, same coin, etc etc. But it stings harder specifically today. All tenets of the so-called "civilized western world" thrown out for greed and evil. We don't deserve space exploration right now.

  • It's being marketed like it's a vanity project, but it's not. This has been in the works for some time and so many people have given everything they have to make it happen.

    Completely agree with you re: climate change being an existential threat, but disagree with your hyperbole about the US being the worst offender. The US should lead because they are supposed to be a world leader - but they alone are not singularly or in majority responsible for climate change.

    Mixing fact and hyperbole together weakens your overall message.

    • I didn’t mean to be hyperbolic, for carbon footprint I’m looking at cumulative footprint since 1750 and not only recent annual footprint. I’m glad we agree, I take your notes.

I find it interesting the MSM is too busy sperging out about Trump to not treat this as page-three news and place it below the cut.

It's also the first woman and black guy to go to the moon, for those keeping score at home.

  • Trump scored an own goal. Military conflict tends to hijack the front page.

Really hoping those of us who think NASA has jumped the shark won't have to keep ourselves from saying "I told you so" next week out of respect for the dead.

This is four people putting their lives at risk for poor engineering and bad project management.

The "right stuff" applies to the engineers too, but they've all unfortunately left Boeing and NASA.

This opinion may be unpopular here but it's hard to get excited about a colossal waste of taxpayer money after all the damage DOGE did. I don't understand how these NASA missions with questionable scientific value and obscene budgets get off the ground.

I mean I do understand, NASA funding is important to oligarchs. But still.

  • I personally find the grind easier when there also big things happening. You can't just cook the same, most basic, cheapest meal every day for your family and expect them to be happy. Who wants to join a club that doesn't do anything interesting? Same with society. It sometimes needs to dream, to aspire and inspire. To lift peoples head from the toil and look up.

  • Artemis was already set in stone well before DOGE came about and IMO if the federal government is going to set mountains of cash on fire I'd rather it be to NASA than half the crap the government wastes every year.

    • My point is that DOGE killed a bunch of government programs that help people while saving no money, yet this giant waste of money survived. Cancelling Artemis II alone in favor of III would save a billion dollars by itself.
