Top 10 Things You Didn't Know About the Moon
NASA has sent two probes on a collision course with the moon in hopes that the impact will reveal signs of water. That's right: water on the moon. A look at some more little-known facts about that pie in the sky
Searching for the Lunar Jackpot Ice
It may not sound like precision science, but researchers are hopeful that plowing a spacecraft into the moon's surface may reveal a hidden layer of frozen water beneath the surface. On Oct. 9, a NASA satellite will hurl a spent rocket into a dark and frigid lunar crater at 5,600 m.p.h.; the impact will equal the force of 1.5 tons of TNT and kick up a massive, six-mile-high plume of dirt and debris. The satellite the Lunar Crater Observation and Sensing Satellite, or LCROSS will then photograph and study the plume for evidence of water or ice from colliding comets. After a few minutes of observation, the space vehicle will plunge into the moon's surface as well. Images taken by an Indian satellite earlier this year suggested there was indeed water on the moon; confirming the discovery would be a major boon for scientists who dream of humans inhabiting the moon, Mars and other planets someday.
