I'm fascinated by comments like this one, which relate a historical narrative explaining what motivated some event. How do I tell if it's true? What would it mean for it to be false? If it's true (which it is, presumably,) could you tell another story that was just as true, but completely different? There's nothing controversial about the idea that the space program was motivated by the desire to test military techno…

This is something I recently ran into in another thread, and I didn't get into it there because it seemed too meta and unproductive, but this seems like a good opportunity. When we talk about history we are not talking about a binary system, we're talking about experiences related through perspectives. There is rarely an absolute truth to history, and the longer back we go the less certain our understanding tends to…

It is very easy to conflate the motivations of the individual with the motivations of the institutions they are associated with, and this frequently ends up cheapening one or the other.

Very well put.

It would be a mistake to see the space race as something which was "only" about military ambition. It was about different things to different people, and it grew more meanings over time.

But, though there are a thousand different histories that can be written about any event, some historical perspectives are more useful than others for answering particular questions. For example, when you ask "how come the country was happy to write NASA a series of blank checks during the 1960s, but not since?" it's valuable to remember the military angle. In the 1960s the development of better space technology was understood to be a matter of life and death for millions if not billions. Now... not so much.

This seems like a really good way to evaluate historical scholarship (amongst other metrics, of course, unless Mencius Moldbug and Howard Zinn happen to be our greatest living historians.)

I think that Moon is much important milestone than mars in the shorterm. The main reason is that Moonh is the huge resource of Helium-3, which should be a main energy resource of the next centuries. Who dominate the moon will also dominate the energy of the future. This is the main reason, why Chine, USA and Russia take a look more at the Moon than Mars.

Without knowing anything specific, I'd venture to guess that the distance has something to say too.

it needs competition, private companies would be all over this if they could profit from space exploration. Setup a law that states that any landing on the planet will get the lander all land for 250 miles, and you'd have hundreds of missions lifting off trying to get a piece of the pie.

Who cares about earthly laws in space? You can take whatever you can lay claim on.
