What this page covers

This register includes robotic lunar and planetary missions from the NASA/NSSDC chronology, supplemented with solar probes, L1 missions and confirmed recent launches. Failed launch attempts are included. Crewed flights, space telescopes, Earth satellites and unlaunched projects are excluded. One entry may group several vehicles; rovers, landers and mission extensions are generally listed with their parent mission. This is therefore not a count of every individual spacecraft.

A documented catalogue, not a real-time tracker: an initial objective does not mean the destination was reached or the mission still operates. Not every gravity-assist flyby is indexed. Coverage depends on available sources and is not an exhaustive register of every payload or prototype. Dates refer to launch from Earth, in UTC when available.
