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 ...
Juno. The Juno spacecraft was launched on August 5, 2011 (UTC). The trajectory used a gravity assist speed boost from Earth, accomplished by an Earth flyby in October 2013, two years after its launch on August 5, 2011. [45] In that way Juno changed its orbit (and speed) toward its final goal, Jupiter, after only five years. Parker Solar Probe
In gravitationally bound systems, the orbital speed of an astronomical body or object (e.g. planet, moon, artificial satellite, spacecraft, or star) is the speed at which it orbits around either the barycenter (the combined center of mass) or, if one body is much more massive than the other bodies of the system combined, its speed relative to the center of mass of the most massive body.
The Juno spacecraft's suite of science instruments will primarily characterize and explore the three-dimensional structure of Jupiter's polar magnetosphere, auroras and mass composition. [4] As Juno is a polar-orbit mission, it will be possible to measure the orbital frame-dragging , known also as Lense–Thirring precession, caused by the ...
The Gravity Science experiment and instrument set aboard the Juno Jupiter orbiter is designed to monitor Jupiter 's gravity. [1][2][3] It maps Jupiter's gravitational field, which will allow the interior of Jupiter to be better understood. [3] It uses special hardware on Juno, and also on Earth, [1] including the high-gain K-band and X-band ...
The Juno was spin-stabilized and arrived at Jupiter orbit in 2016. [6] The launches of Pioneer 10 and Pioneer 11 probes on two Atlas Centaur vehicles in 1972 and 1973 employed Star 37 rocket motors that were spin-stabilized in order to inject the satellites into the high-energy hyperbolic orbits necessary to achieve solar system escape velocity ...
e. In spaceflight an orbit insertion is an orbital maneuver which adjusts a spacecraft ’s trajectory, allowing entry into an orbit around a planet, moon, or other celestial body. [1] An orbit insertion maneuver involves either deceleration from a speed in excess of the respective body's escape velocity, or acceleration to it from a lower speed.
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 ...
