Interplanetary mission

An interplanetary mission is a voyage or trip through outer space involving more than one planet. As of 28th November 2015, there have been no manned interplanetary missions. So far, all manned missions have been in Earth's orbit or to its Moon. A large number of robotic interplanetary missions have been performed by the NASA, the Soviet Union (and later by Roscosmos), Indian Space Research Organisation, Japan Aerospace Exploration Agency and the European Space Agency.
