List of lunar probes

From Wikipedia, the free encyclopedia

This is a list of robotic space probes that have flown by, impacted, orbited or landed on the Moon for the purpose of lunar exploration, as well as probes launched toward the Moon that failed to reach their target.

Surveyor 3 on the Moon.
The first image returned by Luna 3 showed the far side of the Moon

The crewed Apollo missions are listed at List of missions to the Moon.

Major programs encompassing several probes include:

Second confirmation of water on Moon by Chandrayaan-1's Moon Mineralogy Mapper that observed reflectance spectra of water ice.

Key

Colour key:

  Mission or flyby completed successfully (or partially successfully)       Failed or cancelled mission
  Mission en route or in progress (including mission extensions)   Planned mission
  • means "tentatively identified", as classified by NASA . These are Cold War-era Soviet missions, mostly failures, about which few or no details have been officially released. The information given may be speculative.[needs update]
  • Date is the date of:
  • closest encounter (flybys)
  • impact (impactors)
  • orbital insertion to end of mission, whether planned or premature (orbiters)
  • landing to end of mission, whether planned or premature (landers)
  • launch (missions that never got underway due to failure at or soon after launch)
In cases which do not fit any of the above, the event to which the date refers is stated. Note that as a result of this scheme missions are not always listed in order of launch.
  • In the case of flybys (such as gravity assists) that are incidental to the main mission, "success" indicates the successful completion of the flyby, not necessarily that of the main mission.
