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
Space Interferometry Mission assuming that 40% of mission time is allocated for the planet search, SIM Lite could have surveyed: Aside from searching for Earth-sized planets SIM Lite was scheduled to perform what has been dubbed the "Broad Survey". The Broad Survey would have looked at approximately 1,500 stars to help determine the abundance of Neptune-mass and larger planets around all star-types in Earth's sector of the Milky Way. A third part of the planet finding mission was the search for Jupiter-mass planets around young stars. The survey would have helped scientists understand more about solar system formation, including the occurrence of hot
