Ebb and Flow, NASA's Gravity Recovery And Interior Laboratory, or GRAIL spacecraft, have officially begun collecting science data as they orbit the moon. Scientists will use the information gathered by the twin spacecraft to produce a high-resolution map of the lunar gravitational field. That should provide unprecedented detail about the moon's internal structure and composition, and lead to a better understanding of how Earth and other rocky planets in the solar system formed. Science activities are expected to conclude on May 29. Also, Station Science on Fire, NASA Administrator Charles Bolden joins The White House to encourage engineering students to "Stay With It", "G.E.M.S." at Stennis Space Center, an honor for the late NACA test pilot Scott Crossfield and more!
