In this Aug. 20, 2013 photo provided by NASA, engineers prepare to install the Lunar Atmosphere and Dust Environment Explorer (LADEE) spacecraft into the fairing of the Minotaur V launch vehicle nose-cone at NASA's Wallops Flight Facility in Wallops Island, Va. On Friday, April 18, 2014, flight controllers confirmed that the orbiting spacecraft crashed into the back side of the moon as planned, just three days after surviving a full lunar eclipse, something it was never designed to do. During its $280 million mission, LADEE identified various components of the thin lunar atmosphere — neon, magnesium and titanium, among others — and studied the dusty veil surrounding the moon, created by all the surface particles kicked up by impacting micrometeorites.
