05-Oct-05 | GP-B mission complete
Gravity Probe B has completed its primary mission, having collected more than 50 weeks of precision orbital data since its launch aboard Delta 304 on 20 April 2004. The data have been downloaded to computers at the mission operations center at Stanford University, where analysis and validation are expected to take as long as a year. Scientists hope the data will verify two effects predicted by Einstein: the geodetic effect of a mass warping local spacetime, and the frame-dragging effect of a rotating mass dragging spacetime around with it.
