Voyager 1 Spacecraft Voyager 1 is a 722-kilogram space probe launched by NASA on September 5, 1977 to study the outer Solar System. Max speed: 62,136 km/h Comet ISON's average speed 67,957mph Launch date: September 5, 1977 Cost: 250 million USD Voyager 1 is a 722-kilogram (1,592 lb) space probe launched by NASA on September 5, 1977 to study the outer Solar System. Operating for 36 years and 19 days as of September 24, the spacecraft communicates with the Deep Space Network to receive routine commands and return data. At a distance of about 125.75 AU (1.881×1010 km) from the Sun as of 24 September 2013,[3][4] it is the farthest manmade object from Earth.[5] The primary mission ended on November 20, 1980, after encounters with the Jovian system in 1979 and the Saturnian system in 1980. It was the first probe to provide detailed images of the two planets and their moons. As part of the Voyager program, like its sister craft Voyager 2, the spacecraft is in an extended mission to locate and study the regions and boundaries of the outer heliosphere, and finally to begin exploring the interstellar medium. On September 12, 2013, NASA announced that Voyager 1 had crossed the heliopause and entered interstellar space on August 25, 2012, making it the first manmade object to do so.[6][7][8][9][10][11] As of 2013, the probe was moving with a relative velocity to the Sun of about 17 km/s (38,000 mph; 61,000 km/h).[12] The probe is expected to continue its mission until 2025, when it will be no longer supplied with enough power from its generators to operate any of its instruments
