It's been a while since I've talked space. This is a good of topic as any.
In just about an hour, the Mars Reconnaissance Orbiter will start braking to orbit Mars. Doesn't sound bad, but NASA is 2 for 4 in orbit attempts.
NASA is suppose to have live coverage on NASA TV from 3:30 to 6:00 PM ET.
I hope this works and they get the MRO into orbit.
There are several instruments on this, but the one that has me most intrigued is a High Resolution camera that can phone items as small as a dining room table on the surface of MARS.
UPDATE: The MRO succesfully entered MARS orbit this afternoon. SPACE.com has a full MRO Mission to MARS page that shows info on the current mission.
