NASA TO BOMB MOON TWICE ON OCTOBER 9TH
Two U.S. spacecraft are set to crash on the moon Friday. On purpose. And we're all invited to watch. NASA's Lunar Crater Observation and Sensing Satellite is scheduled to drop its Centaur upper-stage rocket on the lunar surface at 7:31 a.m. ET. NASA hopes the impact will kick up enough dust to help the LCROSS probe find the presence of water in the moon's soil. Four minutes later, the LCROSS will follow through the debris plume, collecting and relaying data back to Earth before crashing into the Cabeus crater near the moon's south pole. The LCROSS is carrying spectrometers, near-infrared cameras, a visible camera and a visible radiometer. These instruments will help NASA scientists analyze the plume of dust -- more than 250 metric tons' worth -- for water vapor. The orbiting Hubble Space Telescope and NASA's Lunar Reconnaissance Orbiter will watch, and photograph, the collisions. And hundreds of telescopes on Earth also will be focused on the two plumes. NA
