NASA Gravity Probe B Mission, Testing Einstein’s Theory of Gravity Completes First Year in Space

Is Einstein’s general theory of relativity correct? Testing two extraordinary predictions of that theory is the goal of Gravity Probe B, or GP-B, a satellite that just marked its first anniversary in space. Published in 1916 and hailed as one of the most brilliant creations of the human mind, Albert Einstein’s general theory of relativity weaves together space and time into a four-dimensional “fabric,” called spacetime, and defines gravity as…

NASA’S Gravity Probe B Mission Completes Data Collection

Almost 90 years after Albert Einstein first postulated his general theory of relativity, scientists have finished collecting data to put it to a new, different kind of experimental test. NASA’s Gravity Probe B satellite has been orbiting the Earth for more than 17 months. It used four ultra-precise gyroscopes to generate the data required for this unprecedented test. Fifty weeks worth of data has been downloaded from the spacecraft and…
