Explain about JUNO MISSION of NASA.
Answers
Answer:
SATCAT no. 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. ... Juno's mission is to measure Jupiter's composition, gravity field, magnetic field, and polar magnetosphere.
Step-by-step explanation:
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; July 4 U.S. time),[4][7] to begin a scientific investigation of the planet.[8] After completing its mission, Juno will be intentionally deorbited into Jupiter's atmosphere.[8]
Juno's mission is to measure Jupiter's composition, gravity field, magnetic field, and polar magnetosphere. It will also search for clues about how the planet formed, including whether it has a rocky core, the amount of water present within the deep atmosphere, mass distribution, and its deep winds, which can reach speeds up to 618 kilometers per hour (384 mph).[9]
Juno is the second spacecraft to orbit Jupiter, after the nuclear powered Galileo orbiter, which orbited from 1995 to 2003.[8] Unlike all earlier spacecraft sent to the outer planets,[8] Juno is powered by solar arrays, commonly used by satellites orbiting Earth and working in the inner Solar System, whereas radioisotope thermoelectric generators are commonly used for missions to the outer Solar System and beyond. For Juno, however, the three largest solar array wings ever deployed on a planetary probe play an integral role in stabilizing the spacecraft as well as generating power.[10]
The Juno spacecraft, which successfully entered the orbit of Jupiter on July 4, 2016, will for the first time peer below the dense cover of clouds to answer questions about the gas giant and the origins of our solar system.
Juno's primary goal is to reveal the story of Jupiter's formation and evolution. Using long-proven technologies on a spinning spacecraft placed in an elliptical polar orbit, Juno will observe Jupiter's gravity and magnetic fields, atmospheric dynamics and composition, and evolution.

End of mission (deorbit into Jupiter) - July 2021. NASA has approved an update to Juno's science operations until July 2021. This provides for an additional 41 months in orbit around Jupiter and will enable Juno to achieve its primary science objectives. Juno is in 53-day orbits rather than 14-day orbits as initially planned because of a concern about valves on the spacecraft's fuel system. This longer orbit means that it will take more time to collect the needed science data.
