The Gravity Recovery and Interior Laboratory (GRAIL) mission is a Discovery Program mission which will use high-quality gravity field mapping of the Moon to determine its interior structure. Maria Zuber of the Massachusetts Institute of Technology is GRAIL's principal investigator. NASA's Jet Propulsion Laboratory, will manage the project.
The gravity mapping technique is similar to that used by Gravity Recovery and Climate Experiment (GRACE), and the spacecraft design is based on XSS-11.[1]
GRAIL will be launched in 2011.
