      "text": "The GEOS (Geodetic Earth Orbiting Satellite) Program developed three satellites for geodetic studies and for satellite-to-satellite tracking. GEOS 1 launched on November 6, 1965, and was a gravity-gradient-stabilized, solar-cell powered spacecraft that carried electronic and geodetic instrumentation. GEOS 1 was also known as Explorer 29. GEOS 2 launched on January 11, 1968, and was identical to the GEOS 1 satellite and was also known as Explorer 36. GEOS 3 launched on April 9, 1975, and was later renamed the Geodynamics Experimental Ocean Satellite. GEOS 3 was an octahedron spacecraft, topped by a truncated pyramid, with a parabolic reflector for a radar altimeter on the flat bottom side.",
