I'm a little late with this considering the space shuttle has already landed, but it's pretty cool nonetheless:
The seven astronauts aboard the shuttle Discovery are up and eager a few hours to themselves today as they prepare for a Saturday landing.
NASA’s Mission Control here at the Johnson Space Center roused the astronauts at 3:32 a.m. EDT (0732 GMT) with the song “Crystal Frontier” by the band Calexico, a tune chosen for shuttle commander Mark Kelly by his wife Gabrielle Giffords, a U.S. Congresswoman from Arizona, and his two daughters.
Also, if, like me, you're a fan of the band, you'll be happy to know that their new album, Carried to Dust, will be out on September 9th. Gives you something to look forward to beyond the long, grueling summer months.
