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…

‘Short Visit’ to United States Lasts 40 Years for Scientist Leading NASA Mission to Test Einstein Theory

In 1960, Dr. C. W. Francis Everitt ventured from his home country of Great Britain for “two or three years” to conduct physics research in the United States. More than 40 years later, he’s still here. And when Gravity Probe B — a NASA-sponsored experiment to test Albert Einstein’s General Theory of Relativity — was launched April 20, it represents the culmination of decades of his career Everitt devoted to…

World’s Most Precise Gyroscopes Ready to Test Einstein Theory

A NASA spacecraft designed to test two important predictions of Albert Einstein’s general theory of relativity is set to launch from Vandenberg Air Force Base, Calif., at 1:09 p.m. EDT, April 17. NASA’s Gravity Probe B mission, also known as GP-B, will use four ultra-precise gyroscopes, orbiting the Earth in a unique satellite, to experimentally test two extraordinary predictions of Einstein’s 1916 theory that space and time are distorted by…

Relativity Mission Achieves Two Major Milestones

The NASA Gravity Probe B (GP-B) Relativity Mission has successfully mated its science payload to its spacecraft and after successful systems testing, the GP-B space vehicle was shipped to Sunnyvale, Calif., on Feb. 9, 2002, to prepare for upcoming rigorous environmental tests. “These milestones are a huge accomplishment for this dedicated team,” said Gravity Probe B program manager Rex Geveden, of NASA’s Marshall Space Flight Center in Huntsville, Ala. “The…
