Satellite To Test Einstein Predictions

NASA and Stanford University officials say a $750 million satellite designed to test two fundamental predictions made by Albert Einstein is finally ready for launch.

The move comes 45 years after it was first proposed at the dawn of the space age.

Since 1959, Gravity Probe B has overcome a half-dozen attempts at cancelation, countless technical hurdles and several delayed launches.

The spacecraft is now scheduled to begin its 16-month mission following an April 17th liftoff.

The unmanned, Earth-orbiting probe is designed to test two of Einstein´s predictions about the nature of space and time, and how the Earth and other bodies warp and twist the fabric that combines the two.
