Welcome
The Gravity Recovery And Interior Laboratory (GRAIL) mission will create the most accurate gravitational map of the moon to date, improving our knowledge of near-side gravity by 100 times and of far-side gravity by 1000 times. The high-resolution gravitational field, especially when combined with a comparable-resolution topographical field, will enable scientists to deduce the moon's interior structure and composition...

The two GRAIL spacecraft will also serve as eyes on the moon for Earth's students through MoonKAM, an exciting program for middle-school kids. Teachers can register for MoonKAM and give their students the opportunity to take their own pictures of the moon.
