EXOSAT
(European X-ray Observatory Satellite, HELOS)
(1980s European space X-ray telescope)
EXOSAT was a 1980s space X-ray telescope
operated by the European Space Agency.
(It has no relation to exosatellites.)
It used lunar occultation observations
to add precision to its observations, having been
placed in a highly eccentric orbit to
assist in this and to reach far enough from Earth that
X-rays are unimpeded.
Its surveys included a slew survey,
its new discoveries designated by the prefix EXO.
