After 45 years of planning, the Gravity Probe B is expected to launch on April 17. Near-perfect spheres will be placed in orbit 400 miles above the poles. This should provide scientists with a space/time reference, thus testing Einstien's ideas that gravity is a field distorting space and time rather than a force transmitted simultaneously as two objects cross paths.
