To celebrate the anniversary of the first manned moon landing, Google has a new site up: http://moon.google.com. If you zoom in close enough, you can see what the moon is made of ;-) (thanks to diana for pointing this out)

Freshman year, one of my classes was actually taught by former astronaut, Jeffrey Hoffman. MIT has also produced the most astronauts than any other private university (more here). You could be next!
