The magnetosphere of Jupiter is the largest planetary magnetosphere in the Solar System, extending up to 7,000,000 kilometers (4,300,000 mi) on the dayside and almost to the orbit of Saturn on the nightside. [17] Jupiter's magnetosphere is stronger than Earth's by an order of magnitude, and its magnetic moment is approximately 18,000 times ...
The following is a chronology of discoveries concerning the magnetosphere. 1600 - William Gilbert in London suggests the Earth is a giant magnet. 1741 - Hiorter and Anders Celsius note that the polar aurora is accompanied by a disturbance of the magnetic needle. 1820 - Hans Christian Ørsted discovers electric currents create magnetic effects.
Diagram of IMAGE spacecraft Launch of IMAGE spacecraft aboard of Delta 277.. IMAGE was the first spacecraft dedicated to imaging the Earth's magnetosphere. [10] IMAGE was a spacecraft developed by the Medium-class Explorer (MIDEX) program, and it was the first spacecraft dedicated to observing the magnetosphere of the Earth, producing comprehensive global images of plasma in the inner ...
MMS mission overview video Visualization of the spacecraft orbit transition. The MMS mission consists of four spacecraft. Each has a launch mass of 1,360 kg (3,000 lb). [6] In their stowed launch configuration, each are approximately 3.5 by 1.2 m (11.5 by 3.9 ft), and when stacked together they have a total height of 4.9 m (16 ft). [6]
As with Earth's magnetosphere, the boundary separating the solar wind's plasma from that within Saturn's magnetosphere is called the magnetopause. [2] The magnetopause distance from the planet's center at the subsolar point [ note 1 ] varies widely from 16 to 27 R s (R s =60,330 km is the equatorial radius of Saturn).
The amount of solar wind energy and plasma entering the actual magnetosphere depends on how far it departs from such a "closed" configuration, i.e. the extent to which Interplanetary Magnetic Field field lines manage to cross the boundary. As discussed further below, that extent depends very much on the direction of the Interplanetary Magnetic ...
Short video featuring commentary by David Sibeck, project scientist for the THEMIS mission, discussing a visualization of reconnection fronts. A substorm , sometimes referred to as a magnetospheric substorm or an auroral substorm , is a brief disturbance in the Earth's magnetosphere that causes energy to be released from the " tail " of the ...
The magnetosphere is defined by the extent of Earth's magnetic field in space or geospace. It extends above the ionosphere , several tens of thousands of kilometres into space , protecting Earth from the charged particles of the solar wind and cosmic rays that would otherwise strip away the upper atmosphere, including the ozone layer that ...
