The THEMIS mission began in February 2007 as a constellation of five NASA satellites (A to E) to study energy releases from the Earth's magnetosphere. As of 2023, three of the satellites orbit the Earth within the magnetosphere, while two have been moved into orbit around the Moon since 2010. Those two (B and C) were renamed ARTEMIS after their arrival on the Moon. All satellites are still active
