Three New Discovery Missions

Three missions were selected for concept studies:

-- The Origins Spectral Interpretation, Resource Identification and Security (OSIRIS) mission would survey an asteroid and provide the first return of asteroid surface material samples to Earth. Michael Drake of the University of Arizona, Tucson, is OSIRIS's principal investigator. NASA's Goddard Space Flight Center, Greenbelt, Md., would manage the project.

-- The Vesper mission is a Venus chemistry and dynamics orbiter that would advance our knowledge of the planet's atmospheric composition and dynamics. Gordon Chin of Goddard is Vesper's principal investigator. Goddard would manage the project.

-- The Gravity Recovery and Interior Laboratory (GRAIL) mission would use high-quality gravity field mapping of the moon to determine the moon's interior structure. Maria Zuber of the Massachusetts Institute of Technology, Cambridge, Mass., is GRAIL's principal investigator. NASA's Jet Propulsion Laboratory, Pasadena, Calif., would manage the project.
