Courtesy of The Planetary Society, you can submit your name to be included on NASA's OSIRIS-REx mission for free. Your name will travel with a spacecraft, which launches in 2016, to collect a sample from the asteroid Bennu. It'll return to earth, hopefully with the sample, in 2023.

Ah, this one is not US only, I hope.

Woo~ This is really cool and a little bit creepy. 2023? I hope they don't get abducted by aliens. :P
