Yes, but a big reason payloads cost so much is the need for extreme mass optimization, which is driven entirely by limitations in launch technology.
When launching large masses to high energies gets cheaper, payloads have a chance to get cheaper, too.
Not just mass optimization either. Intense effort and cost are expended through verification because a single payload simply must work. But using commodity hardware with reduced verification effort, launching many, and tolerating some amount of attrition has resulted in reduced costs for Starlink.
Testing of using commodity parts was part of the Mars helicopter and it worked well enough that making many of them seems plausible. I'd love to see multiple drones flying faster/further than rovers. Just not really sure what instruments would make them useful.
That's another great example. And ridesharing on the mission allowed them to prove it very inexpensively and with much lower risk than a dedicated mission.
So once Starship flies routinely could we mass produce rovers and launch them 30 at a time?
I think the question of technical possibility answers differently from the question of organizational feasibility. Starlink is optimizing costs because they have a financial incentive to do so. The less each satellite costs, and costs to maintain, the more income they make. I fear incentives are not so direct in governmental orgs. Outside contractors performing most of the work have outsized influence, and incentive to inflate costs. Budgetary decision makers all want to see investment in their own districts.
I think Starlink and cubesats have definitely proven the approach can reduce costs.
The engineering does not seem as challenging to me as figuring out how to get such a policy approved and pushed through all the administrative and decision making layers without watering down and budgetary inflation.
Maybe if we launched 30 Starships carrying 30 rovers each. With only 30 units, the prices would likely be similar to current commercial satellites, which are already built on standardized platforms.
