WASHINGTON -- NASA will host a news conference at 11 a.m. EDT (8 a.m. PDT), on Thursday Aug. 25, to discuss the upcoming launch of the Gravity Recovery And Interior Laboratory (GRAIL) mission. Scheduled to launch Sept. 8, 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.

The event will take place at NASA Headquarters in Washington. It will air live on NASA Television and the agency's website.

The news conference panelists are:
-- Jim Green, director, Planetary Science Division, NASA Headquarters, Washington
-- Maria Zuber, GRAIL principal investigator, Massachusetts Institute of Technology, Cambridge
