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
NASA Uranus orbiter and probe of depth. The probe would be 30 kg in mass and about 0.5m in diameter. There is also a study that recommended a medium-class concept for the New Frontiers program to develop such an orbiter for Uranus. NASA Uranus orbiter and probe A Uranus orbiter and probe is a mission concept for study of the planet Uranus. It was first recommended to NASA in 2011 by its Planetary Science Decadal Survey 2013–2022. NASA evaluated in 2017 twenty different mission designs submitted by the scientific community, considering mission trades, trajectories, and the technology required for specific objectives. Because of planet position
