Juno in launch configuration. 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.

Avoiding signals from the spacecraft is another reason MAG is placed at the end of the solar panel boom, about 10 m (33 feet) and 12 m (39 feet) away from the central body of the Juno spacecraft. [1] [2] The MAG instrument is designed to detect the magnetic field of Jupiter, which is one of the largest structures in the Solar System. [3]
At the end of its mission, Juno is planned to be deorbited and burned up in Jupiter's outer atmosphere [25] [26] to suppress the risk of biological contamination of its moons. [27] In October 2021, the Lucy spacecraft was launched from Cape Canaveral Space Force Station Space Launch Complex 41 on a mission to study eight different asteroids ...
Juno ' s orbit is highly elongated and takes it close to the poles (within 4,300 kilometres (2,700 mi)), but then far beyond Callisto's orbit, the most distant Galilean moon. [12] This orbital design helps the spacecraft (and its complement of scientific instruments) avoid Jupiter's radiation belts, which have a record of damaging spacecraft ...
JADE-E and JADE-I are sensors that are spread out on the spacecraft, and the EBox is located inside the Juno Radiation Vault. [2] EBox stands for Electronics Box. [2] JADE-E is for detecting electrons from 0.1 to 100 keV, and there are three JADE-E sensors on Juno. [2] JADE-I is for detecting ions from 5 eV to 50 keV. [2]
Juno Radiation Vault (the box being lowered onto the partially constructed spacecraft) in the process of being installed on Juno, 2010 Juno Radiation Vault is shown attached, but with the top open and some of the electronics boxes inside the vault can be seen The cube shaped JRV can be seen in between the un-wrapped main dish and the larger hexagonal main spacecraft body.
On this perijove, Juno flew by Europa at a distance of 352 km (219 mi). Orbital period around Jupiter reduced to 38 days. [1] 16 October Lucy: First gravity assist at Earth: Target altitude: 300 km (190 mi). 14 November CAPSTONE: Lunar orbital insertion First mission to use a Near-rectilinear halo orbit around the Moon 21 November Artemis 1
In January 2021, NASA officially extended the Juno mission through September 2025. While Juno ' s highly inclined orbit keeps the spacecraft out of the orbital planes of Io and the other major moons of Jupiter, its orbit has been precessing so that its close approach point to Jupiter is at increasing latitudes and the ascending node of its ...
