LADEE, the spacecraft that completed 100 days of science before entering into a decaying orbit, is getting ever-closer to crashing into the moon. Now NASA is running a contest to see who can guess when exactly that crash will take place.

The last planned maneuver is on April 15th, after which little LADEE will be in full-shadow for the upcoming eclipse. Head over to the NASA website to put in your entry for date, hour, and minute of the impending crash, and win yourself some ever-lasting bragging rights.
