Pioneer 11 comme la sonde jumelle Pioneer 10 avait pour mission de faire une première reconnaissance des régions externes du Système solaire qui n'avaient jamais été explorées jusque-là. Shortly afterwards, Pioneer 11 maneuvered to a spot in the universe that was out of view from Earth.It's possible Pioneer 11 might still be hailing home, although it should be noted Pioneer 10's signal became too faint to hear in 2002.Like Pioneer 10, Pioneer 11 carries a gold plaque on board intended to tell extraterrestrials a bit about where it came from. The planet also boasts a collection of exotic, and still mysterious, moons. As late as 1995, two of Pioneer 11's instruments were still working. To watch just the voyagers, and follow their path from launch till now, please see the Later ones went farther into space, with Pioneer 10 successfully launching toward Jupiter and its moons in 1972.NASA wanted to take Pioneer 11 a step further. The mission ended in 1995 and Pioneer 11 is on a trajectory to take it out of the solar system.Pioneer 11, the sister spacecraft to Pioneer 10, was the first human-made object to fly past Saturn and also returned the first pictures of the polar regions of Jupiter.After boost by the TE-M-364-4 engine, the spacecraft sped away from Earth at a velocity of about 32,000 miles per hour (51,800 kilometers per hour), thus equaling the speed of its predecessor, Pioneer 10.During the outbound journey, there were a number of malfunctions on the spacecraft—including the momentary failure of one of the RTG booms to deploy, a problem with an attitude control thruster, and the partial failure of the asteroidal dust detector—but none of these jeopardized the mission.Pioneer 11 passed through the asteroid belt without damage by mid-March 1974. L'attraction de la planète géante accéléra Pioneer 11 jusqu'à 173.000 km/h et la dévia vers Saturne. Other objectives included the study of the interplanetary medium found beyond Mars’ orbit, study of Jupiter’s environment, and study of the asteroid belt and whether it would harm future space missions to the outer solar system.

Beyond Earth: A Chronicle of Deep Space Exploration, 1958-2016 After Pioneer 10 emerged through the asteroid belt, Pioneer 11 was launched on a similar trajectory on April 5, 1973, like Pioneer 10, … Elle passera à proximité d'une étoile de cette constellation dans 4 millions d'années. The next full Moon will be midday on Monday, August 3, 2020. After its launch in 2021, NASA’s James Webb Space Telescope will observe Saturn as part of a comprehensive solar system program. Le dernier contact avec Pioneer 11 survint en novembre 1995. The spacecraft made its closest … The vehicle then used Jupiter’s massive gravitational field to swing back across the solar system to set it on a course to Saturn.After its Jupiter encounter, on April 16, 1975, the micrometeoroid detector was turned off since it was issuing spurious commands which were interfering with other instruments. The spacecraft recorded the planet’s overall temperature at minus 292 degrees Fahrenheit (minus 180 degrees Celsius) and photographs indicated a more featureless atmosphere than that of Jupiter. Besides the many images of the planet (and better pictures of the Great Red Spot), Pioneer 11 took about 200 images of the moons of Jupiter. The Next Full Moon is the Strawberry Moon, Mead Moon, Honey Moon, Vat Purnima, Poson Poya, and the LRO Moon. Pioneer 11 live position and data. Fun — and even educational — NASA activities to do at home. This page shows Pioneer 11 location and other relevant astronomical data in real time. Partie le 5 avril 1973, après sa jumelle Pioneer 10, la sonde Pioneer 11 a montré pour la première fois les pôles de Jupiter en décembre 1974, puis frôlé Saturne en 1979. By this time, it was traveling faster than any human-made object at the time, more than 106,000 miles per hour (171,000 kilometers per hour).Because of its high speed during the encounter, the spacecraft’s exposure to Jupiter’s radiation belts spanned a shorter time than its predecessor although it was actually closer to the planet.Pioneer 11 repeatedly crossed Jupiter’s bow shock, indicating that the Jovian magnetosphere changes its boundaries as it is buffeted by the solar wind. The first probes, launched in the late 1950s, aimed for the moon. Dubbed the "Get breaking space news and the latest updates on rocket launches, skywatching events and more!Thank you for signing up to Space. Images collected during Cassini's superclose orbits in 2017 are giving scientists new insight into the complex workings of the rings. The next full Moon will be early Saturday morning, September 14, 2019. Pioneer 11 launched in 1973 on a mission to explore the Asteroid Belt, Jupiter and Saturn.
