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 Shuttle Atlantis after its previous mission, STS-51-J in October 1985. "Atlantis" was then used for ten flights between 1988 and 1992. Two of these, both flown in 1989, deployed the planetary probes "Magellan" to Venus (on STS-30) and "Galileo" to Jupiter (on STS-34). With STS-30 "Atlantis" became the first shuttle to launch an interplanetary probe. During another mission, STS-37 flown in 1991, "Atlantis" deployed the Compton Gamma Ray Observatory. Beginning in 1995 with STS-71, "Atlantis" made seven straight flights to the former Russian space station Mir as part of the Shuttle-Mir Program. STS-71 marked a number of firsts in human spaceflight: 100th
