Using a precision formation-flying technique, the twin GRAIL spacecraft will map the moon's gravity field. The data collected will enable scientists to deduce the moon's interior structure and composition, and to gain insights into its thermal evolution.

GRAIL launched Sept. 10, 2011, from Launch Complex 17-B at Cape Canaveral Air Force Station in Florida. GRAIL will help answer longstanding questions about Earth's moon and provide a better understanding of how Earth and other rocky planets in our solar system formed.
