This orbit enables observations of the magnetosphere’s response to varying solar wind conditions from the full range of vantage points over time scales encompassing all space weather phenomena. Furthermore, this orbit allows scientific return 100% of the time from at least a single instrument and up to 83% of the time from all instruments ...
Canadian Geospace Monitoring (CGSM) is a Canadian space science program that was initiated in 2005. CGSM is funded primarily by the Canadian Space Agency , and consists of networks of imagers, meridian scanning photometers , riometers, magnetometers , digital ionosondes , and High Frequency SuperDARN radars.
Magnetic pulsations are extremely low frequency disturbances in the Earth's magnetosphere driven by its interactions with the solar wind. [1] These variations in the planet's magnetic field can oscillate for multiple hours when a solar wind driving force strikes a resonance. [2] This is a form of Kelvin–Helmholtz instability. [1]
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 ...
IMP-8 was followed by ISEE-3, which was placed near the L 1 Sun-Earth Lagrangian point, 235 Earth radii above the surface (about 1.5 million km, or 924,000 miles) and continuously monitored the solar wind from 1978 to 1982. The next spacecraft to monitor the solar wind at the L 1 point was WIND from 1994 to 1998.
Animation of Advanced Composition Explorer's orbit viewed from the Sun Earth · Advanced Composition Explorer ACE in orbit around the Sun–Earth L 1 point. Advanced Composition Explorer (ACE or Explorer 71) is a NASA Explorer program satellite and space exploration mission to study matter comprising energetic particles from the solar wind, the interplanetary medium, and other sources.
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 ...
If the pressure from particles within the magnetosphere is neglected, it is possible to estimate the distance to the part of the magnetosphere that faces the Sun.The condition governing this position is that the dynamic ram pressure from the solar wind is equal to the magnetic pressure from the Earth's magnetic field: [note 1] (()) where and are the density and velocity of the solar wind, and ...
