Gravity Probe B Wraps Up Observations

[FLO]

After 17 months of productive data collection, NASA's Gravity Probe B satellite has gathered all the data it needs to pronounce Einstein right or wrong. The probe was launched in April 2004, with four spherical gyroscopes designed to test two of Einstein's predictions about General Relativity: how the Earth's gravity warps space, and how its rotation drags space around with it. Scientists will now spend about a year analyzing the data before presenting their conclusions.
