Welcome home!
NASA sure has been busy lately. You may have heard that
Discovery touched down safely on Tuesday, back from 2 weeks at the international space station. There were some concerns about damage due to significant amounts of foam insulation breaking off during launch, which is what caused Columbia's destruction in 2003. Damage turned out to be minor, and a couple spacewalks later the shuttle was given a clean bill of health. NASA emphasized that the reason they're observing this degree of foam shedding is that they're actually looking for it now, and there's no doubt that the situation has improved dramatically from 2 years ago. Even so, further shuttle flights are
grounded until the situation is addressed to NASA (and its now-paranoid review board)'s satisfaction. You may recall
my opinions on overdoing the safety factor in spaceflight.
The launch of the Mars Reconnaissance Orbiter, scheduled for today, has
been delayed until tomorrow while they check out a couple of navigation components on its booster rocket. The rocket is a newly-developed Atlas V, designed for heavy lifts, and this launch will mark its first payload. The Orbiter is very exciting: carrying cameras that can resolve objects 3 feet in diameter and deep-ground-penetrating radar, its primary goal is the discovery of underground aquifers (water, people) and it may even be able to find the crashed Beagle probe.
And this is good for a laugh:
Space Adventures thinks they can convince people that rather than taking a vacation cruise in the Caribbean, they should
go to the moon instead. And that they should pay $100 million for the privilege. They even think they can do it by 2008. Good idea, fellas, but you may want to coordinate your day planners with NASA: they're the only ones planning on having a rocket that could take people to the moon anytime soon. And they won't have it until the Shuttle is phased out. And that's not til 2010. And if I know my US government organizations, by "2010" they mean "when Congress and our board of directors stop haggling over funding. Don't call us, we'll call you. Probably sometime before 2025."
