Kosmos 159 (Russian: Космос 159, meaning Cosmos 159), E-6LS No.111, was one of many satellites designed during the Soviet space program given the designation Kosmos. This satellite was specifically designed to be a high orbit satellite used to gain information on trajectory anomalies caused by the Moon's gravitational pull. This data would have been vital to the Soviet space program and could have been key in successful crewed missions to the Moon. This mission was also used to test radio communications in space.
