NASA’s Next Fifty Years

Thoughts from Bob Zubrin:

If NASA wants to send humans to the Moon or Mars, it should not spend billions on random cost-plus infrastructure projects that supposedly might come in handy if some day there were a program to go. Instead it should just take competitive bids for delivery services. It should incentivize the development of additional systems, including rovers, habitats, life support, power units, space suits and so on, the same way.

It’s pretty clear that, whatever individuals might desire, institutionally, neither NASA or Congress care whether or not they send humans to the moon or Mars, and haven’t since 1972. I do think, though, that despite Bob’s skepticism, the entrepreneurs will get us there.

The Dragon Investigation

This is good news. Hans Koenigsmann just did a press conference with Kathy Lueders in which they announced the root cause of the explosion. Apparently it was a failed check valve prior to the test as they were pressurizing, that resulted in some NTO setting fire to titanium piping, causing an overpressure which then cascaded to mixing of the hypergolics. At least that’s my preliminary understanding. They’re going to go from check valves to burst disks, and the fix doesn’t seem to be on the critical path to getting to a November flight.

Here is the full SpaceX statement. And “hyperbolic” typo fixed in initial post.

Lunar Resources

Is there a conflict between science and sustainability?

Meanwhile, there is a symposium on space settlement in DC today. You can follow the livestream.

[Late-afternoon update]

I know this is what you’ve all been waiting for: The Slate article about this crap.

Though most of the symposium was actually useful and interesting, ignoring the nonsense about colonialism in North America.
