 


| Probes and spacecraft launched from Earth. Spacecraft and probes have visited other planets, and searched our solar system. Below is a list of the probes and spacecraft.. The list includes past, current, and future probes as well as failed and cancelled missions. The list of probes and spacecraft is organized as follows.  List of planetary probes and spacecraft sent to explore the planets and solar system. - spacecraft - name of the spacecraft.
- organization - primary agency/agencies.
- date - date of closest encounter (flybys, impactors), orbital insertion to end of mission (orbiters), landing to end of mission (landers).
- 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 budged 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.
- ref - references.
