You can now send your name to the Moon for posterity, courtesy of the Planetary Society and the SELENE spacecraft. Just point your browsers to the Planetary Society here, and add your name to the list. You can also print the PDF certificate so that you can have a hard copy that you can brag about to your friends.
SELENE, which stands for Selenological and Engineering Explorer, will be launched by the Japanese Aerospace Exploration Agency in July or August this year.
You have until February 28, 2007 to submit your names.
