Goes-19 weather satellite enters Safe Hold mode

7 hours ago (spaceweather.gov)

Former GOES engineer here. At this point I'd almost be surprised if 19 didn't have something go wrong. We had issues on almost every other satellite. GOES-17 had the loop heat pipe anomaly(Supposedly from someone stepping on it in the cleanroom...), GOES-15 (IIRC) had a micrometeorite strike, and GOES-13 had a fuel tank anomaly right before deorbit.

GOES-16 and GOES-17 are on-orbit spares, so in the extremely unlikely event of a total failure there's at least another spacecraft on-orbit ready to take up station.

That said, I have every faith in the GOES team to get to the bottom of this. They're the best, and I often wish I was back there working with them.

  • From now on, every time I see the word "anomaly" I will assume it is an euphemism for "someone stepped on it".

  • > Supposedly from someone stepping on it in the cleanroom

    I would be too embarrassed to return to work if I did that.

    • How do they track that? Is there a log book where someone has to write to?

      "Observed EMP555 step on loop heat pipe. Conducted visual inspection of the affected area; no damage found, pipe remains nominal."

I love how "safe mode" for a satellite is basically: "extend solar panels, turn self towards sun, don't do anything unnecessary, wait for further instructions".

  • They should rebrand it as "Praise the Sun" mode. We are sorry, GOES-19 is temporarily unavailable during a planned solar worship break of indefinite length.

Interestingly, I noticed this in aproximately real time. I had been checking up on the visible-light geocolor composite images every hour or so to look at the massive plume of Canadian wildfire smoke that was turning the skies in the northeast dark orange yesterday.

I haven't interacted with the GOES site or cared too much about the image output until the last 2 days, and the it immediately broke. Somewhat humorous to me.

From the latest update (https://www.ospo.noaa.gov/operations/goes/status.html#datafi...), it looks like they're already restoring systems.

``` Update #3: DCS and SAR have returned to service as of 1630Z. Engineers will now work to restore ABI and expect imaging to resume by 1900Z. Image navigation may be slightly degraded for the first hour after imaging starts. The GOES-19 instruments will be restored in the following order:

    ABI
    GLM
    SUVI
    CCOR-1/EXIS/MAG/SEISS

The recovery process to return all GOES-19 instruments to normal operations is projected to take approximately 8 hours.

Update #2: The GOES-19 Safehold has been resolved and engineers are working to prepare for restart of the onboard instruments. More information on the recovery timeline will be provided when known. ```

As an aside, I'm always surprised how US Gov websites look like they've been made in Dreamweaver in about 2006. Not even seemingly with a emphasis on usability either.

  • While it may not be flashy, I personally find the GOES sites extremely useful. Things are often simply placed at obvious and expected URLs, so scraping or monitoring is extremely easy.

    I wrote the script that provides the GOES NavSum [1] and it pretty much just builds a standardized text file and drops it in the folder. The neat thing is that this makes it really easy to programmatically scrape and parse the data.

    I wrote a personal script at one point that would download the GOES-EAST CONUS image and both EAST and WEST full disk images and composite them into a wallpaper. At one point my server had 500GB of archived GOES imagery. I liked to joke with my former coworkers that I could report image anomalies before they notice because my desktop wallpaper would change every 10 minutes.

  • The ones that look old are old. The USG has newer design systems that you'll see used on many of the websites that have been redesigned more recently: https://designsystem.digital.gov/

    This admin gutted both NOAAs budget and workforce so a website redesign is probably low priority at the moment.

    • Sites like NASA's APOD have not changed by design. So many third parties have been built up around sites that any change [w|c]ould break so much for no effective gain. Same holds true when people ask why things like NOTAMs and even NOAA's alerts are formatted the way they are.

  • Lots of the web still looks like this when you step outside the comfort zone of big tech search engines, content streaming sites, and social media.

  • The link OP submitted appears to be a webpage displaying a screenshot of another web page, and the image aspect ratio has been altered. It's so comically bad it had to be on purpose, or someone is doing their web dev in MS Word.

    Edit: I think actually it's a screenshot of a screenshot even, and this appears to be the entire design of spaceweather.gov. What in the holy heck is going on there? This has to be a top 10 worst website designs of all time.

  • You can thank AccuWeather for nerfing any funding for site modernization. I'm surprised the tiled radar map hasn't had the Biden performance fixes reverted.

A safehold is like maintenance mode, shutting down all non-essential systems, after it detects something is wrong. Doesn't necessarily mean it is gone for good, but not a good sign.

  • What is it that the space aliens don't want us to see? The obvious conclusion is that they are hiding their invasion fleet arrivals inside of hurricanes. The proof will be when the system comes back online and only permits us to see ordinary weather.

Very unfortunate timing given the ongoing wildfires and associated smoke spreading across eastern North America in recent days.

Invasion of Cuba incoming?

  • No, you can’t see ships with this satellite. Too small. Besides, Russia and China have way better satellites that they’ll happily share intel from with Cuba.
