Lunar exploration

Lunar exploration is the investigation of the Moon using telescopes, spacecraft, landers, rovers, and human missions. It ranges from remote observation to direct study on the lunar surface.

Luna 2: A Soviet spacecraft that became the first human-made object to reach the Moon in 1959. Its impact marked the first direct contact with the lunar surface.
Lunar orbiter: A spacecraft placed in orbit around the Moon to observe or measure it remotely. Orbital instruments map large regions without touching the surface.
Space Race: The Cold War competition between the United States and Soviet Union for achievements in spaceflight. Its rivalry drove the first rapid sequence of lunar missions.
Lunar geology: The study of the Moon's materials, surface features, and geological history. Mission observations and samples reconstruct how the Moon formed and changed.
Apollo lunar samples: Rocks and soil collected by astronauts during the Apollo missions and returned to Earth. Their laboratory study transformed knowledge of lunar age, composition, and history.
Apollo 11: The 1969 mission that carried the first humans to land on the Moon. Its landing made crewed lunar surface exploration a reality.
Lunar lander: A spacecraft designed to descend to and operate on the lunar surface. A lander provides direct measurements at a chosen site.
Luna program: A series of Soviet robotic missions that explored the Moon from 1959 onward. It achieved early lunar impacts, landings, rover operations, and sample returns.
Lunar water: Water present on the Moon as ice, hydroxyl, or molecules bound to minerals. Locating and characterizing lunar water informs both science and mission planning.
Giant-impact hypothesis: The hypothesis that the Moon formed from debris after a large body struck the early Earth. Lunar samples and measurements became central evidence for models of lunar origin.
