What Does EXOSAT Stand For?

EXOSAT stands for European X Ray Observatory Satellite

EXOSAT, or European X Ray Observatory Satellite, was a pioneering space mission launched in 1983 by the European Space Agency (ESA). Designed to study X-ray sources in the universe, EXOSAT provided valuable insights into black holes, neutron stars, and other high-energy phenomena. Equipped with advanced X-ray detectors and a unique orbit that allowed uninterrupted observation, the satellite significantly contributed to our understanding of cosmic X-ray emissions until its mission concluded in 1986.
