Gravity Probe B (GP-B) is a NASA physics mission to experimentally investigate Einstein’s 1916 general theory of relativity—his theory of gravity. GP-B uses four spherical gyroscopes and a telescope, housed in a satelliteorbiting 642 km (400 mi) above the Earth, to measure, with unprecedented accuracy, two extraordinary effects predicted by the general theory of relativity: 1) the geodetic effect—the amount by which the Earth warps the localspacetime in which it resides; and 2) the frame-dragging effect—the amount by which the rotating Earth drags its local spacetime around with it. GP-B tests these two effects by precisely measuring the precession (displacement)angles of the spin axes of the four gyros over the course of a year and comparing these experimental results with predictions from Einstein’s theory.

Gravity Probe B (GP-B) is a NASA physics mission to experimentally investigate Einstein’s 1916 general theory of relativity—his theory of gravity. GP-B uses four spherical gyroscopes and a telescope, housed in a satelliteorbiting 642 km (400 mi) above the Earth, to measure, with unprecedented accuracy, two extraordinary effects predicted by the general theory of relativity: 1) the geodetic effect—the amount by which the Earth warps the localspacetime in which it resides; and 2) the frame-dragging effect—the amount by which the rotating Earth drags its local spacetime around with it. GP-B tests these two effects by precisely measuring the precession (displacement)angles of the spin axes of the four gyros over the course of a year and comparing these experimental results with predictions from Einstein’s theory.
