The Gravity Probe B mission provided two new quantitative tests of Einstein’s theory of gravity, general relativity (GR), by cryogenic gyroscopes in Earth’s orbit. Data from four gyroscopes gave a geodetic drift-rate of −6601.8±18.3 marc-s yr and a frame-dragging of −37.2±7.2 marcs yr, to be compared with GR predictions of −6606.1 and −39.2 marcs yr (1 marc-s=4.848×10 radians). The present paper introduces the science, engineering, data analysis, and heritage of Gravity Probe B… CONTINUE READING
