NASA decides Spirit is henceforth to be a lander
There was a press briefing today that announced the official end of efforts to extricate Spirit from her sand trap at Troy. Instead, the rover drivers will now focus on improving the chances that Spirit will survive the coming winter so that she can carry on doing science once the power situation improves in the spring.

ESA mission analyst suggests 2010 AL30 might be Venus Express rocket
2010 AL30 zipped past us harmlessly about five hours ago. Because of its one-year orbital period, many people speculated it might be a manmade object, but 2010 AL30 might, in fact, be artificial.
