Understanding the Unusual LCROSS Ejecta Plume

LCROSS was unusual mission, in that it relied on an impact to be able to study a planetary body. Not only was the mission unusual, but so was the [ejecta][1] plume produced by the slamming a spent [Centaur][2] rocket booster into [the Moon][3]. “A normal impact throws debris out more than up, like an inverted lampshade that gets wider and wider as it goes out,” said Pete Schultz, from Brown University and a member of the LCROSS science team. “But the configuration of the empty rocket booster created a plume that had both a low angle plume but more importantly, also a really prominent high angle plume that shot almost straight up.” This high plume made it possible for debris to be thrown up high enough to be illuminated by [sunlight][4] and studied by the [spacecraft][5] studying the plume.
