Graphic of Jupiter's magnetosphere with Io plasma torus in yellow. Artist generated diagram showing the location of various instruments. MAG is on the lower right of this graphic. Magnetometer (MAG) is an instrument suite on the Juno orbiter for planet Jupiter. [1] The MAG instrument includes both the Fluxgate Magnetometer (FGM) and Advanced ...
The Earth and most of the planets in the Solar System, as well as the Sun and other stars, all generate magnetic fields through the motion of electrically conducting fluids. [54] The Earth's field originates in its core. This is a region of iron alloys extending to about 3400 km (the radius of the Earth is 6370 km).
Magnetosphere. A rendering of the magnetic field lines of the magnetosphere of the Earth. In astronomy and planetary science, a magnetosphere is a region of space surrounding an astronomical object in which charged particles are affected by that object's magnetic field. [1][2] It is created by a celestial body with an active interior dynamo.
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 ...
The MESSENGER mission has triaxial ring-coil magnetometer with a range of +/- 1000 mT and a sensitivity of 0.02 mT, still in progress, the mission is designed to get detailed information about Mercurian magnetosphere. [25] The first use of spherical magnetometer in three axis configuration was on the Ørsted satellite.
Schematic of Earth's magnetosphere, showing the relative position of the magnetosheath. Scientific research into the exact nature of the magnetosheath has been limited due to a longstanding misconception that it was a byproduct of the bow shock/magnetopause interaction and had no inherently important properties of its own.
Surrounding Jupiter's magnetosphere is a magnetopause, located at the inner edge of a magnetosheath—a region between it and the bow shock. The solar wind interacts with these regions, elongating the magnetosphere on Jupiter's lee side and extending it outward until it nearly reaches the orbit of Saturn. The four largest moons of Jupiter all ...
The dipole model of the Earth's magnetic field is a first order approximation of the rather complex true Earth's magnetic field. Due to effects of the interplanetary magnetic field (IMF), and the solar wind, the dipole model is particularly inaccurate at high L-shells (e.g., above L=3), but may be a good approximation for lower L-shells.
