We are saddened by the passing of Jim Lovell, commander of Apollo 13 and a four-time spaceflight veteran.

I think there are only five left, four of whom walked on the Moon. Lovell was the only one who circled it twice, but never set foot on it. It’s getting increasingly possible that they’ll all be gone before another person does, thanks to Congress and feckless administrations over the decades.

Bob Zimmerman has an obituary.

[Saturday-afternoon update]

Here’s the obit from the New York Times. I don’t think this is right, though: “In a nation battered by domestic turmoil and devastated by Vietnam War casualties, the safe return of the astronauts lifted American spirits and renewed attention to the space program, which had drifted in the aftermath of the first two manned landings on the moon.”

Not really. In fact, it was a wake-up call that if they continued to do lunar missions, it was not unlikely that they would lose a crew, and Apollo 13 was part of the impetus to not fly 18 and 19.
