Requiescat in Pace

Twenty years ago today, the space shuttle Challenger exploded 73 seconds after launch. The entire crew was killed: Dick Scobee, Michael Smith, Judith Resnick, Ellison Onizuka, Ronald McNair, Gregory Jarvis and Christa McAuliffe.

Former astronaut John Glenn, a U.S. Senator at the time, said what we were all thinking: that we always knew a day like this would come, but we always hoped it would not be this day.

This is a sad time of year for NASA. Yesterday, January 27, was the thirty-ninth anniversary of the Apollo 1 launchpad fire that killed Gus Grissom, Ed White and Roger Chaffee. Next Wednesday, February 1, is the third anniversary of the breakup on re-entry of shuttle Columbia, which killed Rick Husband, William McCool, Michael Anderson, David Brown, Kalpana Chawla, Laurel Clark, and Ilan Ramon.

Our astronauts are truly the brightest and the best this country has to offer. The things that NASA tries to do are fundamentally difficult, and fundamentally risky. The astronauts are ready to face great risk in order to achieve great things, but they have no intention of throwing their lives away carelessly, and we must never expect them to do so.

Let’s remember the dead astronauts, and honor their memory in the only way that matters: by carrying on their important work with the utmost care for the lives of the living astronauts.

We always know that days like those will come. When the next tragedy comes, as it surely will, let it never be because we valued the lives of our best people too lightly.
