Space probe comet 67P/Churyumov-Gerasimenko in November 2014. First probe to Jupiter. Radio communications were lost with Pioneer 10 on January 23, 2003, because of the loss of electric power for its radio transmitter, with the probe at a distance of 12 billion kilometers (80 AU) from Earth. First probe to fly by Saturn. (Communications were later lost due to power constraints and vast distance.) "Voyager 1" is a 733-kilogram probe launched September 5, 1977. It visited Jupiter and Saturn and was the first probe to provide detailed images of the moons of these planets. "Voyager 1" is the farthest human-made object from
Saturn Atmospheric Entry Probe Saturn Atmospheric Entry Probe The Saturn Atmospheric Entry Probe is a mission concept under study since 2010, where a robotic spacecraft would deliver a single probe into Saturn to study its atmosphere. Due to the orbits and relative positions of Saturn and Earth, launch is proposed for August 30, 2027 for a June 22, 2034 arrival. The mission is under review in order to compete for funding by NASA's New Frontiers Program. To unveil the processes of outer planet formation and Solar System evolution, detailed studies of the composition, structure, and dynamics of giant planet interiors and atmospheres would be
