That’s like saying 25% of Exxon’s development came from tax payer money because the government uses a shitload of oil.
To be fair to NASA and the astronauts, NASA needed humans who behave like military test pilots. In physiology, in reaction time, in crisis management, in following chain of command. And the armed forces were willing to give them access to known quantities.
We didn’t know how control systems would evolve over the next three decades, but the pilots wanted to pilot, and did not trust the control systems. And the irony of it all is that the Space Race was a proxy war for nuclear armament, so control systems needed to be made autonomous anyway.
Better control systems, wider telemetry, and not worrying about incinerating employees let current generation rocketry iterate faster, and do more fucking around and finding out. We found out twice with the shuttle and it killed the program.
It’s curious how much the upper stage now resembles a space shuttle on a ballistic trajectory instead of a glide angle. Very different landing strategies for those two modes of descent…
It's about pumping mass into low Earth orbit, partly for commericial, but mostly military purposes such as Golden Dome. Been in the works for decades and finally here. The people who know are very excited.
SpaceX being their own customer, and a lower priority one, lets them levellize their revenue, which also helps retain staff. And if anyone commoditizes launch systems, they have a hedge against that. However if demand for starlink ever does exceed capacity, the launch side could find their schedules being much more variable.
In software, you see this with priority queues all the time if you know where to look. Someone makes a “low priority” system that soaks up spare capacity. Internal customers become dependent on these systems and then become delay-averse. Meanwhile, other teams also start soaking up that spare capacity, by improved design or feature creep or both. That low priority system becomes starved of resources, and the internal customers start saber rattling. That system gets its own dedicated resources, and now stranded resources climb back to the original levels, if not worse.
Starlink will eventually become the same thing. And I wonder if they will spin it off when that situation arises.
You could say the same thing for terrestrial internet. Not trying to be contradictory, I just find this a very interesting ethical topic.
As a UIUC student used to be fond of reminding me, part of the University of Illinois’ contribution to the old Internet was in a building that, if it were to collapse, would fall outward and not crush the basement. Officially that building was designed so every office has natural light, like a collapsible water cup, but it’s a very interesting coincidence that it (the basement) is bomb proof.

It would be a pretty inefficient way to deploy offensive weapons.
Continuing to iterate on self contained biospheres and long term closed cycle life support? (Not a solved problem!) Working on construction techniques for the Moon or Mars? Studies on the dose response curve for gravity, like sponsoring a spin lab for the ISS to at least see if mice can reproduce in 0.3g? Self contained industrial infrastructure leaning heavily on 3D printers? Psychological research on the best way to build interiors and run social units?
Musk could personally fund all of that with little impact on his net worth.
It’s also decades of work. Some of what I listed is harder than the rockets. Better get started if you want to have a settlement on Mars this century.
Nope. Nothing. Just rockets, the a satellite network that is clearly “dual use.” Then Trump 2.0 and lots of “golden dome” (Star Wars 2.0) talk.
It’s not to go to Mars.
I love space and I hugely admire the engineering achievement, but it’s disappointing to learn for this and many other reasons that the people behind it were not the visionaries they pretended to be. They’re just more territorial apes obsessed with ape tribal stuff like race and nationalism and fighting over dirt at the bottom of a gravity well. Small minds with big toys.
If you make it much cheaper, then everything else flows from that. You no longer have to spend years engineering everything at the cutting edge of your mass budget. You can use off the shelf parts, you can have redundancy.
The gains will come when these flights become commonplace.
That was done and the results were published a few months ago, but the study did not have any relationship with SpaceX.
The results were rather pessimistic for the long-term missions on Moon or Mars.
In my opinion, even if it is possible that humans might support a somewhat lower gravity than mice, the conclusion is that for interplanetary travel humans must use only spaceships that create artificial gravity by rotation.
The results of the study were that mice require a gravity of at least 2/3 of that of Earth to stay in perfect health and of at least 1/3 of that of Earth to avoid extremely severe health damage.
This means that even on Mars the gravity is not sufficient for long-term human life. In an underground Mars base, one could make a part with increased gravity by rotation, where the crew should spend most of the time, but that would increase a lot the complexity of building and maintaining such a base.
Unless someone invents the Epstein drive we aren’t going to have astronauts experiencing acceleration for months rather than minutes of the trip. And the more constant the acceleration the shorter the trip anyway.
The origin of SpaceX with Michael D. Griffin and Pete Worden really make it clear though.
How much time is needed to do the required research? Like, how long it would take to learn how to create an artificial biosphere on a small scale, so you can have a farm on the Moon or Mars? 10 years? 20 years? Maybe 50 years? Isn't now is the good time to start the research?
