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.

The mission was originally scheduled to conclude in February 2018 after completing 37 orbits of Jupiter. However, the mission was extended through 2025 to conduct 42 additional orbits, including close flybys of Jupiter's moons Ganymede, Europa, and Io. [24] At the end of its mission, Juno is planned to be deorbited and burned up in Jupiter's ...
Jovian Auroral Distributions Experiment (JADE) is an instrument that detects and measures ions and electrons around the spacecraft. [1] It is a suite of detectors on the Juno Jupiter orbiter (launched 2011, orbiting Jupiter since 2016). [2] JADE includes JADE-E, JADE-I, and the EBox. [2]
It uses special hardware on Juno, and also on Earth, [1] including the high-gain K-band and X-band communication systems of the Deep Space Network as well as Juno ' s Ka-band Translator System (KaTS). [1] [4] These components work together to detect minute changes in radio frequency (Doppler shift) to measure the spacecraft's velocity over time ...
JIRAM JIRAM data on Jupiter's southern lights, August 2016 Jovian "Hotspot" in visible (top) and near infrared (bottom) from a previous mission. Jovian Infrared Auroral Mapper (JIRAM) is an instrument on the Juno spacecraft in orbit of the planet Jupiter. It is an image spectrometer and was contributed by Italy. [1]
This mission plan was to orbit an asteroid, at the time named 1999 RQ 36 (now 101955 Bennu), by 2020. After extensive measurements, the spacecraft collected a sample from the asteroid's surface for return to Earth in 2023. The mission, minus the cost of the launch vehicle ($183.5 million), is expected to cost approximately $800 million.
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 ...
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 ...
