  • After 30 years in orbit, mission operations for the joint NASA–JAXA Geotail spacecraft have ended.
  • It was launched on July 24, 1992.
  • The mission was part of the International Solar-Terrestrial Physics (ISTP) project.
  • It had gathered an immense dataset on the structure and dynamics of the magnetosphere, Earth’s protective magnetic bubble.
  • Geotail was originally slated for a four-year run, but the mission was extended several times due to its high-quality data return.
  • While one of Geotail’s two data recorders failed in 2012, the second continued to work until experiencing an anomaly on June 28, 2022.
