This weekend JPL has opened their house to the public. Their casa es tu casa. It's like a science Disneyland, complete with all the long lines and crappy food. But watch the video and decide for yourself if it's worth the trip.

You can see the newest Mars Rover unplugged (literally), and also check out a model of that Rover rolling around on rocks -- it looks like some kind of creature.

It'll launch in a year and a half and will take ten months to get to Mars. I hope there are no screaming babies on the rocket ship.
