The Planetary Society’s solar sail spacecraft was in the middle of a critical test as we spoke with the Society’s Bruce Betts and Jason Davis. Mat Kaplan tells Senior Editor Emily Lakdawalla why he’s a bit frustrated by some media descriptions of the beautiful new Hubble image of Mars. And Bruce returns for the regular What’s Up segment, including a chance to win Offworld Trading Company, the new economic strategy game set on a future Mars.
