Satellite To Test Relatively

dude_from_munich writes "Einstein proposed in 1916 that space and time form a structure that can be curved by the presence of a body. Scientists are finally planning to put Einstein's theory of relativity to test after a project delay of 44 years."

Of course GTR has been confirmed many times

[aminorex]

The article as phrased suggests that GTR is hitherto unconfirmed by observational data. That is not the case: The aspects of the General Theory of Relativity which are addressed by this experiment are consistent with experimental data for the perihelion of Mercury which actually predated and motivated the General Theory, and are confirmed every day by gravitational lensing effects used very practically by astronomers, as recently reported here on slashdot.

It's a popular Senior or Graduate physics exercise to design experiments demonstrating GTR -- and a somewhat more ambitious exercise to perform them. This one is notably primarily for being bloody expensive and having blown it's schedule by such a honking big margin.
