When a rocket booster purposefully crashed into a crater near the moon’s south pole Friday, it was one small step for NASA’s LCROSS mission—and one giant white screen for NASA fans watching at home. Space enthusiasts catching the live video feed of the crashing spacecraft at the Newseum in Washington, D.C. or on their computers at home watched as the moon grew larger, until the screen went suddenly and anticlimactically white. The mission—intended to gather data and ascertain whether or not the crater harbored ice—was at least successful, according to the director of NASA. Data will be examined over the next few weeks to determine if ice is present.
