NASA/JPL is building the next mars rover, the Mars Science Laboratory AKA "Curiosity," and you can watch here. Pretty cool stuff. This one is a bit bigger than the last two rovers we sent over and is scheduled to launch a year from now, with a touch down on Mars in August 2012.

Thought that some of the gear heads around here might enjoy watching a space vehicle being built.

Can't embed this, but still I would highly suggest looking this over and checking back every week or so

There are no sacred cows.
