Earth’s closest neighbor is holding a secret. In 1999, hints of that secret were revealed in the form of concentrated hydrogen signatures detected in permanently shadowed craters at the lunar poles by NASA’s Lunar Prospector. These readings may be an indication of lunar water and could have far-reaching implications as humans expand exploration past low-Earth orbit. The Lunar CRater Observing and Sensing Satellite (LCROSS) mission is seeking a definitive answer. | Earth’s closest neighbor is holding a secret.

Although the launch is currently scheduled for 24th April 2009, the primary launch scenario provided in this add-on is the 27th April 2009 due to the mission constraints on the LAN of LRO's final Lunar orbit. The second launch scenario provided is for the 24th April 2009, should you wish to use it. | Although the launch is currently scheduled for 24th April 2009, the primary launch scenario provided in this add-on is the 27th April 2009 due to the mission constraints on the LAN of LRO's final Lunar orbit.
