As most of us know, Dawn is set for launch on June, 20th, 2007. A disc is gonna be sent in the spacecraft, with names of many people around the world recorded inside. Does anybody know when is the disc is gonna be put into the spacecraft, and the most realistic tentative date of launch for the mission? Thanks a lot.
