Viewpoint Finally , results from Gravity Probe B
The great blues singer Etta James’ signature song begins, “At laaasst, my love has come along . . . .” This may have been the feeling on May 4th when NASA announced the long-awaited results of Gravity Probe B [1], which are appearing now in Physical Review Letters[2]. Over 47 years and 750 million dollars in the making, Gravity Probe B was an orbiting physics experiment, designed to test two fu...
متن کاملNewtonian Gravity Predictions For Gravity Probe B
Newtonian gravity and special relativity combine to produce a gravitomagnetic precession of an orbiting gyroscope that is one fourth as large as predicted by General Relativity. The geodetic effect is the same in both cases.

Reisenberger, et al., “A Possible Rescue of General Relativity in Di Herculis,” Astronomical Journal 97, pp. 216-221, 1989. Abstract: The binary DI Her has attracted attention because its low observed rate of apsidal advance, dw/dt = 1.0° ± 0.3°/100yr, appears to contradict general relativity, which see...
متن کاملVLBI for Gravity Probe B. I. Overview
We describe the NASA/Stanford gyroscope relativity mission, Gravity Probe B (GP-B), and provide an overview of the following series of six astrometric and astrophysical papers that report on our radio observations and analyses made in support of this mission. The main goal of this 8.5 year program of differential very long baseline interferometry astrometry was to determine the proper motion of...
متن کاملGravity Probe B: final results of a space experiment to test general relativity.
Gravity Probe B, launched 20 April 2004, is a space experiment testing two fundamental predictions of Einstein's theory of general relativity (GR), the geodetic and frame-dragging effects, by means of cryogenic gyroscopes in Earth orbit. Data collection started 28 August 2004 and ended 14 August 2005. Analysis of the data from all four gyroscopes results in a geodetic drift rate of -6601.8±18.3...
