Kepler

If all goes well, in about seventeen hours, the Kepler mission will be launched. While NASA is hyping the "search for Earth-like planets" aspect of the mission, this space-based telescope will do more than that: it could provide a way for NASA to generate public interest in space exploration (if the press flacks don't screw it up!).

Additional information about the mission here. Images and video here. Alas, while you can "twitter" with the spacecraft and visit its "Facebook" page, there are no paper models to build while you wait for launch! Too "old media", I suppose.
