This is a list of planetary probes , including solar probes and probes to asteroids and comets. It includes past, current, and future probes as well as failed and cancelled missions.
For a list of landers only, see Landings on other planets .
Key
The list is organized as follows:
Spacecraft – name of the spacecraft
† means tentatively identified, as classified by NASA [1] . These are Cold War-era Soviet missions, mostly failures, about which few or no details have been officially released. The data given may be speculative.
Organization – primary agency/agencies
Date – date of closest encounter (flybys, impactors), orbital insertion to end of mission (orbiters), landing to end of mission (landers), launch (launch failures)
Type – type of mission
flyby – the spacecraft is to fly past its target
orbiter – the spacecraft is to study the target from orbit
solar monitor – solar missions, usually located in a halo orbit at the L1 point
lander – the spacecraft is to study the target on its surface
impactor – the spacecraft is to study the target until it hits the target and is destroyed
penetrator – the spacecraft is to penetrate the surface of the target
atmospheric probe /balloon – the spacecraft is to study the atmosphere of the target
sample return – the spacecraft is to return samples to the Earth
Status – current status or the outcome of the mission
success – the mission has fulfilled its primary goals
partial success – the spacecraft did send some data but did not fulfil its goals
failure – no or very little data returned
cancelled – the mission has been cancelled (usually due to budget cuts)
under study – the mission is being studied (not yet approved)
to be launched – the spacecraft has not yet been launched (may be still under construction)
yet to arrive – the spacecraft is on the way to the target
in orbit – the spacecraft is in orbit but has not yet completed its primary mission
operational – the spacecraft has reached the target but has not yet completed its primary mission
Notes – special notes, reasons for failure etc.
Image – if available
