This spacecraft was the first one to fly to Jupiter, Saturn, the Milky Way Galaxy and stars. Close-ups of the planet provided the first observations of the polar regions, as well as some clear images of the Great Red Spot. 23, 1990: Crossed the orbit of NeptuneSept. The Galilean Moons of Jupiter Moons of Saturn, Uranus, & Neptune Rings Kuiper Belt Objects Dwarf Planets Comets Space Junk Asteroids Meteorites Dust and Plasma Extrasolar Planets Missions Pioneer 10 & 11 Galileo Most of the other moons were … Based on the data that was sent back by the space probe, scientists identified plasma in the magnetic field of Jupiter. 45 years ago, Pioneer 11 launched to study Jupiter and Saturn It also provided an accurate mass of Jupiter's moon Callisto. This spacecraft was the first one to fly to Jupiter, Saturn, the Milky Way Galaxy and stars.

Der letzte Kontakt konnte im November 1995 hergestellt werden. Voyager 1's closest approach to Jupiter occurred March 5, 1979. Pioneer 10 passed within 81,000 miles of the cloudtops during its closest encounter with Jupiter. The Pioneer 11 probe was launched on April 6, 1973 at 02:11:00 UTC, by the National Aeronautics and Space Administration from Space Launch Complex 36A at Cape Canaveral, Florida aboard an Atlas-Centaur launch vehicle, with a Star 37E propulsion module. Missions There is no better way to study the outer reaches of our solar system than by sending a spacecraft to have a look. Pioneer 10 (originally designated Pioneer F) is an American space probe, launched in 1972 and weighing 258 kilograms (569 pounds), that completed the first mission to the planet Jupiter. Overview: Galileo discovered four of the larger moons: Io, Europa, Ganymede and Callisto in 1610. Pioneer 10 was launched toward Jupiter in 1972. Find out how we do it and what we know about these extraterrestrial worlds. Diameter: 74,900 miles Orbit: 839-938 million miles One Year: 29 Earth years Die 259 kg schwere Sonde hatte die Aufgabe, die Planeten Jupiter und Saturn zu erforschen.

After Pioneer 10 emerged through the asteroid belt, Pioneer 11 was launched on a similar trajectory on April 5, 1973, like Pioneer 10, on top of an Atlas/Centaur/TE364-4 launch vehicle.

April 6, 1973: LaunchMid-March, 1974: Flew through the asteroid beltDec. It also discovered that Jupiter’s huge magnetic tail is about 800 million km long and covered all the distance between Jupiter and Saturn. It also discovered a previously unknown ring, and … During its flyby of Jupiter Pioneer 11 obtained dramatic images of the Great Red Spot, made the first observation of the immense polar regions, and determined the mass of Jupiter's moon, Callisto. One thing Pioneer 11 discovered about Saturn is that it is composed mainly of liquid hydrogen. At Saturn, Pioneer 11 took the first close-up pictures of the planet. This seemed to require a frighteningly deep dive into the radiation belts, but it could be done NASA launched the two Voyager spacecraft to Jupiter, Saturn, Uranus, and Neptune in the late summer of 1977. Pioneer 10 and 11, along with Voyager I and II, sailed past Jupiter. Its twin probe, Pioneer 10, had launched a year earlier on March 3, 1972. 1, 1979: Saturn flybyFeb. Saturn. 1973-1974: Pioneer 10—the first spacecraft to explore Jupiter up close—and its sister mission, Pioneer 11, make the first close-up measurements of Io. 30, 1995: NASA Ames Research Center made last contact with the spacecraftNov.

Pioneer 11 launched April 5, 1973, on an Atlas-Centaur rocket and cruised easily out of Earth orbit towards Jupiter.
