Objectives and Applications
|
The overall objective is to provide two extremely precise new tests of Einstein's theory of gravity, namely the General Theory of Relativity (formulated in 1916 - it states that gravity affects time and distance, by stretching time and contracting distance in the presence of a gravitational field) by means of observations on gyroscopes in Earth orbit.
