what did pioneer 10 discover

It also observed high-energy ions of aluminum and sodium in the solar wind. Most of the other moons were found by … As the spacecraft did not collide with any particles of substantial size, it passed safely through the belt, emerging on the other side about February 15, 1973. The spacecraft passed by a series of Jovian moons, obtaining photos of Callisto, Ganymede, and Europa (but not of Io, as the photopolarimeter succumbed to radiation by that time). Pioneers 10 and 11 preceded Voyager in outstripping the gravitational attraction of the Sun but on February 17, 1998, Voyager 1 passed Pioneer 10 … NASA maintained routine contact with Pioneer 10 for over two decades until 19:35 UT March 31, 1997, (when the spacecraft was 67 AU from Earth) when routine contact was terminated due to budgetary reasons. [4] An advocacy group named the Outer Space Panel and chaired by American space scientist James A. The spacecraft instruments confirmed that the magnetic field of Jupiter was inverted compared to that of Earth. These were being displayed in real-time back on Earth, and the Pioneer program would later receive an Emmy award for this presentation to the media. Pioneers 10 and 11 were the first spacecraft to visit Jupiter (Pioneer 10 and 11) and Saturn (Pioneer 11 only). By the 29th, the orbits of all of the outermost moons had been passed and the spacecraft was operating flawlessly. Images of Jupiter’s hot spots are key to understanding the role of storms and waves in Jupiter’s atmosphere. Approximately 78 minutes after the closest approach, Pioneer 10 passed behind Jupiter’s limb for a radio occultation experiment. Born from such a mission—one that spans space, time, and perhaps, civilizations—is a … [40][41], On November 6, 1973, the Pioneer 10 spacecraft was at a distance of 25 million kilometers (16×10^6 mi) from Jupiter. It passed within 34,000 km of the cloud tops. Approved in February 1969, Pioneer 11 and its twin probe, Pioneer 10, were the first to be designed for exploring the outer Solar System. [43], The trajectory of the spacecraft took it along the magnetic equator of Jupiter, where the ion radiation was concentrated. It was launched on March 2, 1972, by an Atlas-Centaur expendable vehicle from Cape Canaveral, Florida. Acting as pathfinders for the Voyager missions, the vehicles provided the first up-close science observations of these planets, as well as information about … Approved by NASA in February 1969,[7] the twin spacecraft were designated Pioneer F and Pioneer G before launch; later they were named Pioneer 10 and Pioneer 11. [15], After March 31, 1997, Pioneer 10's weak signal continued to be tracked by the Deep Space Network to aid the training of flight controllers in the process of acquiring deep-space radio signals. [51] As the spacecraft headed outward, it again passed the bow shock of Jupiter's magnetosphere. Pioneer 10, launched on the 3 rd of March 1972, was the first man-made object to fly out of our solar system. No fragments larger than a millimeter were observed in the belt, indicating these are likely rare; certainly much less common than anticipated. New results from NASA's Juno mission suggest that either "sprites" or "elves" could be dancing in the upper atmosphere of Jupiter. Pioneer's last, very weak signal was received on Jan. 22, 2003.
