This Wednesday, January 21, astronomer Anthony Colaprete of NASA’s Ames Research Center will give a non-technical, illustrated talk on Prospecting for Water on the Moon: The Upcoming LCROSS Mission.

Sometime this year NASA will purposely crash two spacecraft into a permanently shadowed crater in one of the Moon’s polar regions. Yes, purposely.

The Lunar Crater Observation and Sensing Satellite (LCROSS) mission is to determine the presence or absence of water (ice and vapor), hydrocarbons and hydrated materials. The LCROSS mission is going to do this by directly impacting one of the permanently-shadowed regions near the moon’s pole and creating a crater, throwing debris and potentially water ice and vapor above the lunar surface.

The two main components of the LCROSS mission are the Shepherding Spacecraft and the Centaur upper stage rocket. The Centaur rocket will impact the moon causing a cloud of lunar debris. The Shepherding Spacecraft, which has scientific instruments on-board including cameras, will take pictures of the Centaur’s descent and impact into the moon. Four minutes later, the Shepherding Spacecraft follows almost the exact same path as the rocket, descending down through the big plume and analyzing it with special instruments. The Shepherding Spacecraft will then crash into the moon. This impact may be seen using an amateur telescope.
