The Magnetospheric Multiscale (MMS) mission is a NASA space physics observatory consisting of four identical satellites launched in 2015. The spacecraft fly in a tight tetrahedral formation to study the magnetosphere, specifically focusing on magnetic reconnection. This physical process occurs when...
Cluster is a space mission developed by the European Space Agency (ESA) to study the Earth's magnetosphere and its interaction with the solar wind. Launched in the summer of 2000, the mission consists of four identical spacecraft flying in a tetrahedral formation. By maintaining this specific geomet...
Cluster II is an ESA mission consisting of four identical spacecraft launched in pairs aboard Soyuz-Fregat rockets in July and August 2000. Flying in a tetrahedral formation through Earth's magnetosphere in an elliptical polar orbit, the satellites measure magnetic fields, electric fields, and plasm...
THEMIS (Time History of Events and Macroscale Interactions during Substorms) is a NASA mission comprising five identical satellites launched on a single Delta II rocket in February 2007. The spacecraft orbit in formation to measure electric and magnetic fields and charged particles across near-Earth...
NASA's Magnetospheric Multiscale Mission (MMS) is a four-spacecraft constellation launched on March 12, 2015, to study magnetic reconnection in Earth's magnetosphere. The four identical spacecraft fly in a tight tetrahedral formation, sometimes only kilometers apart, enabling three-dimensional measu...
James Van Allen was a pioneering American physicist who fundamentally changed our understanding of space. His work centered around the magnetosphere, specifically the discovery and characterization of Earth’s radiation belts through his development and analysis of data from Explorer 1. This research...
Arase is a Japanese Aerospace Exploration Agency satellite launched in 2016 to study the dynamics of Earth's radiation belts and the mechanisms behind space storms in geospace.
IMAGE (Imager for Magnetopause-to-Aurora Global Exploration) was a NASA satellite launched on March 25, 2000 from Vandenberg Air Force Base aboard a Delta II rocket. It was the first space mission dedicated to imaging Earth's entire magnetosphere, using neutral atom, ultraviolet, and radio plasma im...
Cluster II was a European Space Agency mission consisting of four identical spacecraft launched in 2000 to study Earth's magnetosphere and its interaction with solar wind. Flying in a tetrahedral formation with separations varying from 100 to 10,000 kilometers, the spacecraft provided the first thre...
The Magnetospheric Multiscale (MMS) mission is a NASA space mission launched in 2015 to study the Earth's magnetosphere. It consists of four identical spacecraft flying in a precise tetrahedral formation to gather three-dimensional measurements. The mission's primary scientific goal is to measure an...
THEMIS (Time History of Events and Macroscale Interactions during Substorms) is a NASA mission launched in 2007 comprising five identical satellites. It was designed to investigate the physical processes occurring in the Earth's magnetosphere, specifically pinpointing the origin of magnetospheric su...
Geotail was a joint Japanese and United States space mission launched in 1992 to investigate Earth's magnetosphere, especially the long magnetotail formed on the night side by interaction with the solar wind. The spacecraft measured magnetic fields, electric fields, plasma, and energetic particles w...
Akebono, originally designated EXOS-D, was a Japanese scientific satellite launched in 1989 to investigate auroras and processes within Earth's magnetosphere. Its instruments measured phenomena including electric and magnetic fields, plasma waves, and charged particles in the near-Earth environment....
