My friend who was previously employed by SpaceX who has private shares tried to solicit me to spend 50k at $120/share…..this was two weeks prior to the new funding announcement at $150 billion at $80/share. Do you think my friend knew about the announcement beforehand? Obviously, after the announcement came out I declined the offer.

After almost every accident in Starship development, people start claiming that SpaceX's "fail fast, learn faster" strategy is a mistake and they should go back to the classic Old Space strategies. Is that true? Is it really holding SpaceX back? To answer this question, I made a table of Apollo and Starship program milestones and added to them the projected date of the 1^st manned lunar landing if the Starship program took exactly the same amount of time from that milestone as the Apollo program.

It sounds crazy, but over the last 11 years Starship has been exactly on Apollo’s track with a deviation of ±1.6 year. Does that mean SpaceX will land on the Moon with astronauts in February 2026, as the average says? Probably not, but only because NASA is not so desperate now to approve the landing 1.5 years after the 1^st orbital flight of the Lunar Module and 4.5 months after its 1^st manned flight, as during the Apollo program. Currently, we’re nowhere near the 1968 level of risk tolerance, the US competitor in the space race is nowhere near to a super heavy-lift launch vehicle to the launch pad (like it 55 years ago), the president hasn't a firm deadline and Congress isn't to sign NASA a blank check to fulfill it.

Maybe another strategy would cost them less?

I think most of you have already guessed the answer, but just to be clear. In 2019, SpaceX was spending of their resources on the Starship project, which was in the region of $100-150M. By comparison, the Apollo program spent in current prices on launch vehicles in 1960, eclipsing everything SpaceX had spent on Starship and Raptor development to that point. SpaceX spending of this year is still less than the equivalent of the Apollo spending in 1961. The Apollo program's peak spending of $33.2B on launch vehicles and spacecraft in 1966 is simply unthinkable for SpaceX or even modern NASA.

It's all because of 60 years of technological advancement!

This may look like a legitimate argument at first glance, but is it true in reality? Excluding a experiments, the oxidizer-rich pre-burner was Russian technology, so SpaceX were to invent their own SX500 alloy for the Raptor. Methane-oxygen and full-flow rocket engines existed only as test articles before them. SpaceX also invented a stainless steel alloy for the Starship's hull and large identical hexagonal heat tiles instead of using the unique Space Shuttle tiles. Their idea of using has never been used to assemble a launch vehicles, let alone try to catch a boosters with them. And that's not counting dozens or rather hundreds more other details that we'll probably never know about because of trade secrets and ITAR.

Definitely technology has advanced in 60 years in a several places like computer-aided design and dynamic simulation. But in order to accurately simulate a methane rocket engine, you need to calculate physical parameters at points with chemical reactions running in parallel. So good luck with that! Something tells me that even with it and all the modern computing power you'll end up like Blue Origin your if you despise practical tests. Computer simulations are an addition to testing, not a replacement for it.

So although we have progress in technology, it's not as big as some of you might think. And it's all eaten up by the fact that SpaceX is trying to build a launch vehicle twice as heavy and 3 times more powerful than the Saturn V, which also should be fully and quickly reusable. SpaceX aims to make Starship as much of a technological marvel as Saturn V was in its day. And they're trying to do it with a third of the Apollo era NASA and probably an order of magnitude fewer contractors.
