LARES, the LAser RElativity Satellite, a 14-inch diameter spherical satellite with a mass of 853 lbs., will be launched in late 2010, and will become the densest object in our solar system. Dr. Erricos C. Pavlis has been selected by NASA to be the US PI for the Italian Space Agency's (ASI) LARES satellite mission. He and his team will join their Italian counterpart led by Ignazio Ciufolini, University of Salento at Lecce, to form the International Science Team for LARES. The spacecraft has been been completed this fall (2009), and an analysis center is also being completed for the reduction of the tracking data once the satellite is launched. The satellite's surface will be studded with 92 prisms that will reflect incident light towards the incoming direction. In order to test Einstein's theory of General Relativity (GR), LARES' surface will be shot with laser pulses by ground-based laser tracking stations to measure the distance with mm-accuracy and determine its precise orbit. Validating GR through various tests will help us better understand how our world works and will eventually lead to an understanding of the nature of dark matter and the unification of various theories in physics.
