(1977 X-ray observatory space mission)
The High Energy Astronomy Observatory 1 (HEAO-1 ) was a NASA
spacecraft observing X-rays .
It was launched in 1977 and functioned until 1979.
Among its accomplishments were X-ray sky surveys , such as the
HEAO A-1 X-ray Source Catalog .
Instruments included:
LASS (aka A1 ) - Large-area Sky Survey.
CXE (aka A2 ) - Cosmic X-ray Experiment.
