Atlas 5 Rocket Launches to the Moon

Explanation: This rocket is headed for the Moon. Pictured above , a huge Altas V rocket roared off the launch pad last week to start NASA's first missions to Earth's Moon in 10 years. The rocket is carrying two robotic spacecraft. The Lunar Reconnaissance Orbiter ( LRO ) is scheduled to orbit and better map the Moon, search for buried and hidden ice, and return many high resolution images. Some images will be below one-meter in resolution and include images of historic Apollo landing site s. Exploratory data and images should allow a more informed choice of possible future astronaut landing sites. The Lunar CRater Observation and Sensing Satellite (LCROSS) is scheduled to monitor the controlled impact of the rocket's upper stage into a permanently shadowed crater near the Moon's south pole . This impact, which should occur in about three months, might be visible on Earth through small telescopes .
