On April 10, 2020, the Juno spacecraft observed a fireball on Jupiter that was consistent with the impact of a 1–4-meter (3.3–13.1 ft) meteor. It was the first fireball to be detected by Juno . Researchers estimate Jupiter experiences approximately 24,000 impact events of this size per year—around 2.7 per hour.
Jupiter would deliver about 36 Sv (3600 rem) per day to unshielded astronauts at Io and about 5.4 Sv (540 rems) per day to unshielded astronauts at Europa, [89] which is a decisive aspect due to the fact that already an exposure to about 0.75 Sv over a period of a few days is enough to cause radiation poisoning, and about 5 Sv over a few days ...
Hubble image of the scar taken on 23 July 2009 during the 2009 Jupiter impact event, showing a blemish of about 8,000 kilometres long. [1] In recorded history, the planet Jupiter has experienced impact events and has been probed and photographed by several spacecraft.
Jupiter has been visited by automated spacecraft since 1973, when the space probe Pioneer 10 passed close enough to Jupiter to send back revelations about its properties and phenomena. [ 168 ] [ 169 ] Missions to Jupiter are accomplished at a cost in energy, which is described by the net change in velocity of the spacecraft, or delta-v .
Jupiter might have shaped the Solar System on its grand tack. In planetary astronomy, the grand tack hypothesis proposes that Jupiter formed at a distance of 3.5 AU from the Sun, then migrated inward to 1.5 AU, before reversing course due to capturing Saturn in an orbital resonance, eventually halting near its current orbit at 5.2 AU.
The European Space Agency's Jupiter Icy Moons Explorer (Juice) is amid its voyage to Jupiter with a scheduled 2031 arrival to study Ganymede and Jupiter's other moons, Callisto and Europa.
Images taken of Jupiter by NASA's James Webb Space Telescope show a roaring jet stream over the gas giant's equator that is moving at speeds twice as fast as the winds of a Category 5 hurricane ...
Two other space probes made observations at the time of the impact: the Ulysses spacecraft, primarily designed for solar observations, was pointed toward Jupiter from its location 2.6 AU (390 million km; 240 million mi) away, and the distant Voyager 2 probe, some 44 AU (6.6 billion km; 4.1 billion mi) from Jupiter and on its way out of the ...
