2004-4-21Review of Gravity Probe B 3 Essentials of the GP-B Experiment As described above the geodetic and frame-dragging effects of relativistic gravity should cause the spin axis of a gyroscope in Earth orbit to precess In a polar orbit the geodetic term is orthogonal to the frame-dragging term and about 160 times larger 2016-10-15Gravity Probe B had some predictions of Einstein's relativity to test including the geodetic effect (GE) and the frame dragging effect (FDE) both results of an object moving through space-time To be more specific the GE is movement of an orbiting object causing it to tilt to the side while the FDE is a result of the spinning earth pulling

2013-7-3Status report #: 04-166 Gravity Probe B mission status report Gravity Probe B — a NASA mission to test two predictions of Albert Einstein's Theory of General Relativity — is about half way through the initialization and orbit checkout phase of the mission The mission's operations team has successfully transmitted over 5 000 commands to

2019-3-30Gravity Probe B's mission was to confirm a prediction of Einstein's theory of relativity The physics experiment developed by Stanford University and Lockheed Martin was to observe the magnitude 5 star IM Pegasi for over a year attempting to measure the tiny shifts in the spacecraft gyroscopes' orientation caused by the Lense-Thirring

The Gravity Probe-B cryogenic star-tracking telescope provides the inertial pointing reference as established by a distant 'fixed' guide star with milli-arc-second resolution per year for the NASA/Stanford general-relativity gyroscope experiment The design of the f/27 modified-

2010-6-12I am against this what ever we do it should NEVER exceed the complexity of a XR-Vessel or AMSO because otherwise we would a) need years to develop things b) need years to teach all pilots to fly it Ideally we should maybe have a common base class for all our DLL based vessels that like

Abstract This is the first of five connected papers detailing progress on the Gravity Probe B (GP-B) Relativity Mission GP-B launched 20 April 2004 is a landmark physics experiment in space to test two fundamental predictions of Einstein's general relativity theory the geodetic and frame-dragging effects by means of cryogenic gyroscopes in Earth orbit

Gravity Probe B

MISSION DIRECTOR'S SUMMARY On Mission Day 591 the Gravity Probe B vehicle and payload are in good health All active subsystems including solar arrays/electrical power Experiment Control Unit (ECU) flight computer star trackers and magnetic torque rods gyro suspension system (GSS) and telescope detectors--are performing nominally

2006-5-15Gravity Probe B Design Challenges 1 Design a gyroscope where the drift rate due to classical torques is less than 0 3 mas/yr 2 Measure the gyroscope spin axis orientation relative to a metrology reference frame to an accuracy of 1 mas in 5 hr •Noise • Calibration 3 Determine the orientation of the metrology reference

Experimental tests of gravity performed in the solar system show a good agreement with general relativity The latter is however challenged by the Pioneer anomaly which might be pointing at some modification of gravity law at ranges of the order of the size of the solar system As this question could be related to the puzzles of "dark matter" or "dark energy" it is important to test

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

The Gravity Probe B will launch a payload of four gyroscopes into low-Earth polar orbit to test two extraordinary predictions of Albert Einstein's general theory of relativity: the geodetic effect (how space and time are warped by the presence of the Earth) and frame dragging (how Earth's rotation drags space and time around with it)

2006-7-1By Edward S Calder and Bradley T Jones Gravity Probe B (GP-B) has been called the most sophisticated object ever placed in space Whether this is true or not it is certainly oneof NASA's most complex missions and occupies a unique place in space science history GP-B embodies all aspects of an ideal NASA mission: advancing science (testing Einstein's general theory of relativity
