Posted by 007okhay on Dec. 31, 2011

The NASA has Been successful in putting the first of two gravity mapping satellites in orbit around the Moon. The first one Grail-A spacecraft fired its main engine late on Saturday (GMT) to slow itself sufficiently to take up an elliptical path around the lunar body. Its twin, the Grail-B, will attempt exactly the same manoeuvre on Sunday. And both the satellites will make measurements that are expected to give scientists remarkable new insights into the internal structure of the Moon.
