There are currently various proposed space probes to focus on the exploration of the Solar System. For planned missions to the Moon see the dedicated list of missions to the Moon, with its section future missions. Launched probes are in the List of Solar System probes and the List of active Solar System probes.

Suspended missions The following missions were suspended or cancelled because of political, budgetary, or other reasons. The spacecraft were already assembled at the time of suspension/cancellation, so these missions can be resumed.
+Mission nameCancellation dateDescriptionStatus and reason Janus2023Dual asteroids probeWas expected to be a secondary payload on the Psyche launch. After the delay, it was assessed that Janus wouldn't be able to reach the required trajectory. Both spacecraft were placed into long-term storage.
