In case you didn’t already know, Rand Simberg has a lot of experience with space related issues and thus has some educated observations about the Columbia tragedy. Of course, Insta-man is on this like gangbusters. Laurence Simon, who one would expect to have inappropriate humor, actually has a very touching sentiment about the tragedy.
Me, I don’t usually post on Saturdays anyway and am just going to chill. My prayers go out to the families of the astronauts and to the nation of Israel, who really doesn’t need yet another tragedy.

“The same Creator who names the stars also knows the names of the seven souls we mourn today. The crew of the shuttle Columbia did not return safely to Earth; yet we can pray that all are safely home.”
–President George W. Bush
