The Lunar Crater Observation and Sensing Satellite (LCROSS) was a robotic spacecraft operated by NASA to perform a lower-cost means of determining the nature of hydrogen detected at the polar regions of the Moon . The main LCROSS mission objective was to explore the presence of water ice in

5106-467: Was never flown successfully. A double-launching Soviet Mars 5M (Mars-79) sample return mission was planned for 1979 but cancelled due to complexity and technical problems. NASA 's Viking 1 and Viking 2 were launched respectively in August and September 1975, each comprising an orbiter vehicle and a lander. Viking 1 landed in July 1976 Viking 2 in September 1976. The Viking program rovers were

5180-530: Was the first roving remote-controlled robot to land on any celestial body. The Soviet Union launched Lunokhod 1 aboard the Luna 17 spacecraft on November 10, 1970, and it entered lunar orbit on November 15. The spacecraft soft-landed in the Sea of Rains region on November 17. The lander had dual ramps from which Lunokhod 1 could descend to the lunar surface, which it did at 06:28 UT. From November 17, 1970, to November 22, 1970,

5254-566: Was the first, and to date only, landing on any planet's satellite other than Earth's moon. The proposed U.S. Titan Mare Explorer (TiME) mission considered a lander that would splash down in a lake in Titan's northern hemisphere and float on the surface of the lake for few months. Spain's proposed Titan Lake In-situ Sampling Propelled Explorer (TALISE) mission is similar to the TiME lander but has its own propulsion system for controlling shipping. Vesta ,

5328-412: Was the second lunar mission by India, consisting of a lunar orbiter, a lander named Vikram , and a rover named Pragyan . The rover weighing 27 kg, had six wheels and was to be operated on solar power . Launched on 22 July 2019, the mission entered lunar orbit on August 20. Pragyan was destroyed along with its lander, Vikram , when it crash-landed on the Moon on 6 September 2019 and never got

5402-519: Was the second of two uncrewed lunar rovers landed on the Moon by the Soviet Union as part of the Lunokhod program . The rover became operational on the Moon on January 16, 1973. It was the second roving remote-controlled robot to land on any celestial body. The Soviet Union launched Lunokhod 2 aboard the Luna 21 spacecraft on January 8, 1973, and the spacecraft soft-landed in the eastern edge of

5476-471: Was unknown before Surveyor. The U.S.-crewed Apollo Lunar Modules (1969–1972) with rovers (1971–1972) and late Soviet large robotic landers (1969–), Lunokhods (1970–1973) and sample return missions (1970–1976) used a rocket descent engine for a soft landing of astronauts and lunar rovers on the Moon. The Chinese Chang'e 3 mission and its Yutu (' Jade Rabbit ') rover landed on 14 December 2013. In 2019, China's Chang'e 4 mission successfully landed
