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
Jupiter Magnetospheric Orbiter Jupiter Magnetospheric Orbiter The Jupiter Magnetospheric Orbiter (木星磁気圏オービター, JMO) is a cancelled space probe proposed by the Japanese Aerospace Exploration Agency (JAXA), to undertake detailed "in situ" studies of the magnetosphere of Jupiter as a template for an astrophysical magnetised disk. The JMO was originally proposed in 2006 as the Japanese contribution to the now cancelled Europa Jupiter System Mission (EJSM). Then, it was proposed to be carried to Jupiter by the Jupiter and Trojan Asteroid Explorer (Trojan Asteroid Explorer). The discussion for the international collaboration for a Jupiter mission between ESA and Japan (JAXA) started in 2006. By 2007,
