Juno is a NASA space probe orbiting the planet Jupiter. It was built by Lockheed Martin and is operated by NASA 's Jet Propulsion Laboratory. The spacecraft was launched from Cape Canaveral Air Force Station on August 5, 2011 UTC, as part of the New Frontiers program. [ 6 ]Juno entered a polar orbit of Jupiter on July 5, 2016, UTC, [ 4 ][ 7 ...
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.
1.8 km (1.1 mi) [3][4] Comet Shoemaker–Levy 9 (formally designated D/1993 F2) was a comet that broke apart in July 1992 and collided with Jupiter in July 1994, providing the first direct observation of an extraterrestrial collision of Solar System objects. [5] This generated a large amount of coverage in the popular media, and the comet was ...
The exploration of Jupiter has been conducted via close observations by automated spacecraft. It began with the arrival of Pioneer 10 into the Jovian system in 1973, and, as of 2024, has continued with eight further spacecraft missions in the vicinity of Jupiter and two more en route. All but one of these missions were undertaken by the ...
Jupiter's moons were classified into four groups of four, based on their similar orbital elements. [205] This picture has been complicated by the discovery of numerous small outer moons since 1999. Jupiter's moons are divided into several different groups, although there are two known moons which are not part of any group (Themisto and Valetudo ...
Exploration of Io. Painting illustrating a flyby of Io by the Galileo spacecraft. The exploration of Io, Jupiter 's innermost Galilean and third-largest moon, began with its discovery in 1610 and continues today with Earth-based observations and visits by spacecraft to the Jupiter system. Italian astronomer Galileo Galilei was the first to ...
The Juno spacecraft, which entered into a polar orbit around Jupiter in 2016, flew over the Great Red Spot upon its close approach to Jupiter on 11 July 2017, taking several images of the storm from a distance of about 8,000 km (5,000 mi) above the surface.
NASA's Juno spacecraft has zipped past Jupiter's poles, watched its Great Red Spot churn, and visited its largest moon. 10 years after NASA launched its Juno mission to Jupiter, these are its most ...
