Geotail satellite  

Definition

  • Geotail was a satellite that observed the Earth's magnetosphere. It was developed by Japan's ISAS in association with the United States' NASA, and was launched by a Delta II rocket on 24 July 1992 from Cape Canaveral Air Force Station. The primary purpose of this mission is to study the structure and dynamics of the tail region of the magnetosphere with a comprehensive set of scientific instruments. For this purpose, the orbit has been designed to cover the magnetotail over a wide range of distances: 8 REarth to 210 REarth from the earth. This orbit also allowed it to study the boundary region of the magnetosphere as it skims the magnetopause at perigees. In the first two years the double lunar swing-by technique was used to keep apogees in the distant magnetotail. This involved 14 lunar flybys. In June of 2022, the second and final of Geotails two data recorders failed, jeopardizing science observation. It was decided to terminate the operation, and the spacecraft was deactivated on 28 November 2022. (Wikipedia, The Free Encyclopedia, https://en.wikipedia.org/wiki/Geotail)
