The Phoenix Mars Lander is within an hour of attempting its landing on the Red Planet – if you want to keep tabs on what’s happening live (and you’re on broadband), you can access the live NASA TV feed. NASA TV has interviews and up to date briefings on what’s happening. For more background info on the mission, see MSNBC’s Mars page, and also of course, the official NASA page for the mission.
How things change – when growing up, I was fascinated with the Viking photos as I perused them in a book that was released. Now we have live mission broadcasts, and images as soon as they are received.
Update: Phoenix has landed, all looks good at this time. Even some postcards already!
