Airworthiness For Spacecraft

I missed this earlier in the week, but Mike Snead has a long essay on passenger safety over at The Space Review. It’s a useful history, that touches on many of the themes of my book, but I believe that it’s technologically premature to apply the principles to human spaceflight. Spaceflight participants (not passengers) must be aware of the risks of the varied methods of building spaceships, and accept them accordingly. No one should, at this point in history, get aboard one with the same expection of getting safely off that one does with an airliner, particularly because different people have different risk tolerances and goals. There will come a time when trips to space will be considered common carrier, on certified vehicles, but we are years from that time.

Paul Spudis

This is terrible, and a huge loss to the lunar development community. I just saw him in January at the lunar landing science workshop at Ames. He had finally come around to oppose SLS. Condolences to his family and other friends, RIP, and ad astra.

[Update a few minutes later]

More from Leonard David, who was as shocked by the news as I am. I hadn’t been aware that he had lung cancer.

[Update on June 8, 2021]

Paul’s widow, Anne, asked me to update this post to note that, contra a comment here, Paul had quit smoking in 1988, and was informed by his doctors that it was not the cause of his cancer.

Property Rights On Mars

I don’t know if it will be webcast, but I’m going to be giving a talk tomorrow morning in Pasadena, as part of the final plenary of the Mars Society meeting.

[Update Sunday afternoon]

I think the talk went OK. The crowd was smaller than I expected; I think that the Mars conference in DC has pulled a lot of the audience that Bob used to get for his Mars Society meetings. I called people in the audience “mutant weirdos,” and made a lawyer joke.
