The Moon: Is the US doing it wrong?

‘We have lost a lot of time.’ Former NASA chief says US needs to start over with moon landing plans or risk losing to China | Space

Former NASA administrator Michael Griffin pulled no punches about where he sees America’s current Artemis moon landing program in Congressional testimony today. …

And according to Griffin and the witnesses at the hearing, that dominance might soon cede to China due to policy decisions that continue to plague the Artemis program, NASA’s current planned campaign of moon missions. “Sticking to a plan is important when the plan makes sense. China is sticking to a plan that makes sense. It looks a lot, in fact, like what the United States did for Apollo,” Griffin said. “We have stuck to a plan that does not make sense.” …

If Artemis 3 is delayed to late 2028, there will have been an average of two years between the first three Artemis program missions. The Apollo program, by comparison, launched each of its 11 missions an average of once every 4.5 months between 1968 and 1972. …”

Amazing! We spend more & more on “education”. Technology marches forward at a rapid pace. And yet we cannot do today what we did half a century ago! Future historians will have a lot to say about this … writing in Chinese, of course.

Musk seems to be getting over his aversion to space solar power because of the obvious need for machine learning. He keeps talking about physics thinking from first principles. Well that’s exactly what O’Neil did. Oh did I neglect to mention O’Neill was a physicist?

Because of that Bezos has put more money into utilizing regolith for solar cells than Musk. But whatever ego barriers Musk might have to doing something that looks like it might be following his rival’s lead, well just view that as an energy barrier instead of an ego barrier.

Whoa!

I missed this! He’s out to out-O’Neill Bezos!

An engineering problem with mass drivers that Andy Cutler pointed out to me was the mechanical fatigue suffered by mass driver transients. Paraphrasing the way Andy described it:

“You’re taking a sledge hammer to each coil with every passing mass.”
