Date of landing/impact Coordinates Notes Mars 2 lander: USSR: 27 November 1971: First man-made object on Mars. No contact after crash landing. Mars 3 lander: USSR: 2 December 1971: First soft landing on Mars. Transmission began about 90 seconds after landing. [4]
The exploration mission revealed that Neptune's atmosphere is very dynamic, even though it receives only three percent of the sunlight that Jupiter receives. Winds on Neptune were found to be the strongest in the Solar System, up to three times stronger than Jupiter's and nine times stronger than the strongest winds on Earth.
Cassini–Huygens also flew past Jupiter for a gravity assist on its mission to explore Saturn. Only three of the missions to the outer planets have been orbiters: Galileo orbited Jupiter for eight years, while Cassini orbited Saturn for thirteen years. Juno has been orbiting Jupiter since 2016.

3 September 1976 landed: 334 days (10 mo, 30 d) Viking 2 was the second craft to land on Mars. The Viking orbiter was active until 25 July 1978, the lander until 11 April 1980. [20] [21] Pioneer Venus Orbiter: Venus 20 May 1978 4 December 1978 entered orbit: 199 days (6 mo, 15 d) Pioneer Venus made radar and other observations of Venus.
All but one of these missions were undertaken by the National Aeronautics and Space Administration (NASA), and all but four were flybys taking detailed observations without landing or entering orbit. These probes make Jupiter the most visited of the Solar System 's outer planets as all missions to the outer Solar System have used Jupiter flybys.
