Die 259 kg schwere Sonde hatte die Aufgabe, die Planeten Jupiter und Saturn zu erforschen. Pioneer 11 was launched on 5 April 1973, like Pioneer 10, on top of an Atlas/Centaur/TE364-4 launch vehicle. It also discovered a previously unknown ring, and …

Jupiter's moons are too! This seemed to require a frighteningly deep dive into the radiation belts, but it could be done Voyager 1's closest approach to Jupiter occurred March 5, 1979. Diameter: 74,900 miles Orbit: 839-938 million miles One Year: 29 Earth years April 6, 1973: LaunchMid-March, 1974: Flew through the asteroid beltDec.

Steering Pioneer 11 to Saturn did require a very close approach to Jupiter, about one-third the distance of Pioneer 10’s closest approach. In 1973, NASA launched Pioneer 11, providing scientists with their closest view of Jupiter, from 26,600 miles above the cloud tops in December 1974. This spacecraft was the first one to fly to Jupiter, Saturn, the Milky Way Galaxy and stars. Galileo discovered four of the larger moons: Io, Europa, Ganymede and Callisto in 1610. On 22 January 2003, when Pioneer 10’s signal was last detected, the spacecraft had travelled 82 AU (7.6 billion miles) from Earth, more than twice the distance from the Sun to Pluto. 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. This adjusted the aiming point at Jupiter to 43,000 kilometers above the cloudtops. 45 years ago, Pioneer 11 launched to study Jupiter and Saturn Its twin probe, Pioneer 10, had launched a year earlier on March 3, 1972. One thing Pioneer 11 discovered about Saturn is that it is composed mainly of liquid hydrogen. Pioneer 10 was launched toward Jupiter in 1972. During its flyby of Jupiter in 1974, Pioneer 11 made some amazing discoveries. 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. 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.

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. This spacecraft was the first one to fly to Jupiter, Saturn, the Milky Way Galaxy and stars. 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. Pioneer 11 launched April 5, 1973, on an Atlas-Centaur rocket and cruised easily out of Earth orbit towards Jupiter. After safe passage through the asteroid belt on 19 April 1974, the Pioneer 11 thrusters were fired to add another 63.7 m/sec to the spacecraft's velocity.

Der letzte Kontakt konnte im November 1995 hergestellt werden. Voyager 2's closest approach was July 9 Overview: The first spacecraft to explore Jupiter was Pioneer 10, which flew past the planet in December 1973, followed by Pioneer 11 twelve months later.Pioneer 10 obtained the first-ever close-up images of Jupiter and its Galilean moons; the spacecraft studied the planet's atmosphere, detected its magnetic field, observed its radiation belts and determined that Jupiter is mainly fluid. Pioneer 11 war eine US-amerikanische Raumsonde der Pioneer-Reihe, die am 6. Close-ups of the planet provided the first observations of the polar regions, as well as some clear images of the Great Red Spot. 1, 1979: Saturn flybyFeb.
