Science first today. Then we’ll get to the funny stuff.

In some really depressing news, the Space Shuttle Mission to repair the Hubble Space Telescope one last time may be in serious jeopardy. That satellite collision last week, which you’ve undoubtedly heard about by now, was in the same general orbit level of Hubble, and the debris from the collision significantly increases the likelihood of a debris strike during the servicing mission to unacceptable odds. NASA estimates that the chance for a debris impact will be about 1 in 185, which is over their threshold of 1 in 200. Even a tiny piece of metal the size of a pea or even smaller could do serious damage to an astronaut’s space suit during a spacewalk, and since there were 5 spacewalks planned to service Hubble, well… you can see where this is going. The good news is, they’re pretty sure the International Space Station is not at much risk for impact from the debris, because its orbit is much lower than that of satellites. It’s just beyond the outer edges of earth’s atmosphere, which means there are just enough air molecules floating around to put a slight drag on any space junk at that orbit level, thus said space junk burns up relatively faster than junk at higher orbits. Thus, low earth orbit stays comparatively clear of debris.

Space.com reports on how the discovery of alien life could impact society. According to the article, a panel of scientists sponsored by the SETI Institute and the NASA Astrobiology Institute recently met over 3 days to discuss this and come up with a basic outline of what impacts they thought such discovery could have on human society.

Very good news for Hummer-haters (myself included!): The Tennessean reports that GM has announced that it will discontinue or sell the Hummer brand by March 31st. Let’s hope it’s the former, not the latter. In my opinion, there is no greater symbol of the wasteful and inefficient extravangance that helped get us into this economic shitstorm than the Hummer. Good riddance!

Remember my post about the movie Coraline from a week or two ago? At the time I was unclear as to the extent of They Might Be Giants’ contribution to the soundtrack. Well, turns out that 28-second jingle that plays through one of the TV trailers is it. Stereogum reports that they did some other material for the movie that got canned, because in the end it turned out not to be “dark” enough.
