As Mars draws closer than it’s been in over 59,000 years, the Columbia Accident Investigation Board published its final report, and it doesn’t hold back on NASA’s institutional failings. As I’ve said numerous times before, I very much hope we as a nation reaffirm our commitment to space, although I expect very little leadership in this regard from the Bushies — particularly with all our money currently pouring into Iraq. “‘Kennedy was able to relate space exploration to a greater national cause,’ a Bush adviser said earlier this week. ‘I’m not sure that exists today.’” Well, a greater national cause won’t exist unless it’s articulated and promoted by our elected officials. (Besides, since when has the non-existence of something ever stopped Dubya before?) At any rate, despite the vacuum of leadership in the White House, hopefully NASA will take this moment at the crossroads to get its act together and work to redevelop its vision.
