paragraph_text: Human presence
  
  Humans last landed on the Moon during the Apollo Program, a series of crewed exploration missions carried out from 1969 to 1972. Lunar orbit has seen uninterrupted presence of orbiters since 2006, performing mainly lunar observation and providing relayed communication for robotic missions on the lunar surface.
  
  Lunar orbits and orbits around Earth–Moon Lagrange points are used to establish a near-lunar infrastructure to enable increasing human activity in cislunar space as well as on the Moon's surface. Missions at the far side of the Moon or the lunar north and south polar regions need spacecraft with special orbits, such as the Queqiao and Queqiao-2 relay satellite or the planned first extraterrestrial space station, the Lunar Gateway.
