Friday marked the space shuttle's swan song, as the Atlantis lifted off from the Kennedy Space Center for the program's 135th and final flight. "We are retiring the shuttle in favor of nothing," Michael Griffin, President Bush's NASA administrator, told The Washington Post. Gene Healy has a different take. Here, as usual, Healy writes, doing “nothing” gets a bad rap. Maybe we should be “in favor of nothing” until the advocates of federally funded spaceflight can come up with an argument for it that doesn’t make us spray coffee out of our noses.
