Mission Status
Welcome to our Web site! Whatever your level of knowledge about physics and relativity, we hope you find our site easy to navigate and interesting to browse through.
Though our science team is making good progress and nearing completion of the data analysis, we are now facing funding challenges that may jeopardize the completion of the mission.
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.
