NASA mission to study lunar interior
Posted: Wed, Dec 12, 2007, 8:23 AM ET (1323 GMT)
NASA announced Tuesday that it will launch a mission early next decade to studying the interior of the Moon. The Gravity Recovery and Interior Laboratory (GRAIL) mission will consist of two satellites that will map the Moon's gravity field, allowing scientists to better understand its interior structure. The mission is similar to the US-German GRACE mission that has studied the Earth's gravity field. The $275-million mission, part of NASA's Discovery program of relatively low-cost science missions, is scheduled for launch in 2011.
