Collaborators
GP-B Mission
GP-B was designed to measure two key predictions of Einstein's general theory of relativity by monitoring the orientations of ultra-sensitive gyroscopes relative to a distant guide star. Learn more about the mission.
Technology
Most of the technology required to bring GP-B to the launch pad did not exist when the experiment was conceived in 1959. Learn about the advances in engineering that made it all possible.
Einstein's Spacetime
How did Einstein revolutionize our concepts of space and time? Do they exist absolutely or relative to matter? And how does gravity fit in? Learn more about Einstein's universe.
