Latest post is more of a continuation of this one: https://caseyhandmer.wordpress.com/2021/03/04/sls-what-now/ https://caseyhandmer.wordpress.com/2021/03/04/sls-what-now/
I'm going to presume what author thought and quote him:
------
What does NASA do with teams that cost a few billion dollars a year to feed and whose main expertise is building rockets and space probes whose entire architectural philosophy is threatened by current launch costs, let alone the order of magnitude improvement that’s in the pipeline?
The Perseverance Mars rover cost $2.4 billion, which works out to a few thousand salaries for just under a decade. Thousands of people are needed to build this rover because landing stuff on Mars is so hard that subsystem masses must be tracked to a tenth of a gram, on a system that weighs a tonne. The whole thing is meticulously handcrafted from custom silicon, PCBs, titanium tubes, motors, cameras, and other awe-inspiring instruments. Starship will be able to land 100 of them per flight. Now what? How can NASA feed a team that makes one feather light rover per decade for a billion dollars if the demand just jumped by a factor of a thousand and the unit cost fell by the same amount? Set up a production line? Work out how to make them with a team of ten? Build one every two weeks?
In short, in a world where SLS’s ongoing failure is justified and/or ignored while Starship races towards transformational capabilities, NASA needs to think very deeply about its place in a human spaceflight program that appears poised to proceed without NASA at its center.
-----
So the point is it seems to be a question - what is NASA planning to do AT ALL in the world where Starship is flying?
- kwertyoowiyop 5y agoProbably make more custom satellites for scientific projects. There’s an infinite amount of such work to be done.
- ClumsyPilot 5y ago"Starship will be able to land 100 of them per flight. Now what?" Starship cannot deliver 100 tonnes to mars, only to LEO. The rover was not just a ton, it came with a heatshield and other machinery. Nasa has plenty of other projects, like the SAFE nuclear reactor, and I am sure these teams will be delighted to do something other than track every milligram
- panick21_ 5y agoStarship with refueling is designed for 100 tones to Mars. Actually if you do the math it can be even more. > The rover was not just a ton, it came with a heatshield and other machinery. Great and that was thrown away and didn't add anything to the mission. The actual payload is 1 ton. > Nasa has plenty of other projects, like the SAFE nuclear reactor, and I am sure these teams will be delighted to do something other than track every milligram If they allow them to not work that way. That the whole point. I know for a fact the the people who work on Kilopower are really exited for their reactors to potentially power future Mars base and they really want to be allowed to build larger versions.
