  The Laser Astrometric Test of Relativity (LATOR) is a Michelson-Morley-type
experiment designed to test the Einstein's general theory of relativity in the
most intense gravitational environment available in the solar system -- the
close proximity to the Sun. By using independent time-series of highly accurate
measurements of the Shapiro time-delay (laser ranging accurate to 1 cm) and
interferometric astrometry (accurate to 0.1 picoradian), LATOR will measure
gravitational deflection of light by the solar gravity with accuracy of 1 part
in a billion, a factor ~30,000 better than currently available. LATOR will
perform series of highly-accurate tests of gravitation and cosmology in its
search for cosmological remnants of scalar field in the solar system. We
present science, technology and mission design for the LATOR mission.
