Exploration of Jupiter Exploration of Jupiter The exploration of Jupiter has been conducted via close observations by automated spacecraft. It began with the arrival of "Pioneer 10" into the Jovian system in 1973, and, , has continued with eight further spacecraft missions. All of these missions were undertaken by the National Aeronautics and Space Administration (NASA), and all but two have been flybys that take detailed observations without the probe 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 to reduce fuel requirements
Space probe Transport Network. First man-made object to soft land on the Moon, or any other extra terrestrial surface. First mission to photograph the far side of the Moon, launched in 1959. First robotic sample return probe from the Moon. First rover on Moon. It was sent to the Moon on November 10, 1970. First probe to Mercury. First successful in-place analysis of another planet. It may have also been the first space probe to impact the surface of another planet, although it is unclear whether it reached Venus' surface. The Venera 7 probe was the first spacecraft to successfully soft land
