It is a sad day for Mankind. Seven astronauts died today due to a yet unknown problem with Columbia upon reentry. I heard a former shuttle astronaut remark that the Columbia had been slightly damaged upon liftoff when an object from the launch tower fell and hit Columbia. Until we know more, this speculation makes more sense than any other theory I’ve heard. The only thing that I’m sure about is that this was NOT due to terrorists. The U.S. would be hard pressed to stealthily attack a rapidly moving object (traveling approximately 12,000 miles per hour) over 200,000 feet off the ground. It is beyond the reach of low-tech terrorists on the run.

I recall the demise of the Challenger from a combination of an engineering design flaw and a poor management decision to launch under poor conditions. The shuttle program was grounded for a long time while this problem was studied. I don’t expect a long delay in the next launch after the Columbia’s demise since it is clear that the shuttles are quite capable of safe reentry.

I will note that America’s shuttle fleet is aging. Other then the Endeavor – which replaced the Challenger in 1992 – all of the shuttles are about twenty years old (Columbia first flew in 1981). Nasa’s fleet of space trucks needs upgrading. I hope President Bush and Congress will dedicate monies to build a new generation of space shuttles with current technology. I further suggest that we name the first one the Ilan Ramon. If you are an American citizen and agree with me, please write your representatives. And keep the family, friends, and co-workers of the Columbia in your prayers.
