I am very not brave but I'd volunteer. The trip is far more awesome than anything I have planned for the rest of my life. And if the shield fails on reentry it would only hurt for a few seconds. So if the crew and the backups and their backups read this and have second thoughts, ping me.

The article seems compelling, but experience tells me to get both sides of a story before judging. Anyone know if there's a detailed response from NASA to the article?

There’s been plenty of coverage of this issue, and this article discusses some of the changed they made: https://www.space.com/space-exploration/artemis/the-artemis-...

The only thing the author of this blog piece has to offer that’s new is his very strong personal intuition that the new design hasn’t been properly validated, without any engineering explanation about why the testing the performed won’t adequately simulate real world performance.

> if a commercial crew capsule (SpaceX Dragon or Boeing Starliner) returned to Earth with the kind of damage seen on Orion, NASA would insist on a redesign and an unmanned test flight to validate it. Are you sure about that? https://spaceflightnow.com/2022/05/24/spacex-swapping-heat-s...

Your link says it failed in testing, not in flight.

Earlier quoted context omitted.

And Columbia, too, when they made the decision to reenter without inspection, and reenter instead of waiting for rescue.

A rescue was impractical and potentially riskier no?

Riskier? Didn't they all die. Maybe if you ended up with 2 stranded shuttle crews, but correct me if I'm wrong, and I probably am, but couldn't the shuttle fly without any crew?

Great read and interesting article. Hard to believe that NASA would risk astronauts lives simply to save face, but that appears to be what's going to happen.

They’ve killed dozens during the shuttle program , or did you forget ? Also a number during Gemini, Mercury and Appollo. Terrible safety record , and 5x worse than Soyuz . Shuttle fatality rate was 1/10. Approaching Russian roulette odds

In total, a little over one dozen astronauts died on shuttle flights (14). No astronauts died during Gemini or Mercury. Three died in a test on Apollo 1. The shuttle failure rate was nowhere close to 1/10. In fact, it was 1/67 (2 failures out of 134 flights).

I think they were saying they would sign up just for the experience, even if it's unnecessary to the program.

What I don't get is why the heck are the astronauts willing to risk their lives on something they must know by now is so dangerous? Is it really better to risk death than to risk getting fired?

There aren't many people left who've been that close to the moon. Lots of people would love to be on that list.

It couldn't, for a funny reason. Everything on a Shuttle flight could be automated except lowering the landing gear just before touchdown, which had to be done by hand from inside the cockpit.

There are rumors (that I've never been able to run down) that the astronaut corps insisted on this so the Shuttle could not be flown unmanned.

The author seems to have a pretty extensive history of… strong disdain for Artemis II. While has mentioned concerns about the heat shield before it was in the context of a laundry list of complaints, and it was nowhere close to the top. I’m not a rocket scientist, but then neither is the author.

This comment in dripping with elitism. We trusted the rocket scientists and what did that get us? The Challenger disaster. /s
