The second of NASA's three High Energy Astrophysical
Observatories, HEAO-2, renamed Einstein after launch, was the first fully
imaging X-ray telescope put into space. The few arcsecond angular resolution,
the field-of-view of tens of arcminutes, and a sensitivity several 100 times
greater than any mission before it provided, for the first time, the capability
to image extended objects, diffuse emission, and to detect faint sources. It was
also the first X-ray NASA mission to have a Guest Observer program.
Overall, it was a key mission in X-ray astronomy and its scientific outcome
completely changed the view of the X-ray sky.
