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.
The project scientist is Thomas E. Moore of Goddard Space Flight Center. [13] Education and public outreach is a key aspect of the mission, with student activities, data sonification, and planetarium shows being developed. The mission was selected for support by NASA in 2005.
Solar wind Magnetosphere Ionosphere Link Explorer (SMILE) is a planned joint venture mission between the European Space Agency and the Chinese Academy of Sciences.SMILE will image for the first time the magnetosphere of the Sun in soft X-rays and UV during up to 40 hours per orbit, improving the understanding of the dynamic interaction between the solar wind and Earth's magnetosphere.
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 ...
Magnetic north versus ‘true north’ At the top of the world in the middle of the Arctic Ocean lies the geographic North Pole, the point where all the lines of longitude that curve around Earth ...
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 ...
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 ...
Global Geospace science program (GGS) is designed to improve greatly the understanding the flow of energy, mass and momentum in the solar-terrestrial environment with particular emphasis on geospace. GGS has primary scientific objective of its own: [ 1 ]
