HEAO-2

(High Energy Astrophysics Observatory 2, Einstein Observatory, HEAO-B, High Energy Astronomy Observatory 2) (1978 X-ray observatory space mission)

HEAO-2 (for High Energy Astrophysics Observatory 2, aka High Energy Astronomy Observatory 2, Einstein Observatory or HEAO-B) was a NASA X-ray observatory in space from 1978 to 1982. It was part of a program that included HEAO-1 and HEAO-3. HEAO-2 instruments:

HRI - High Resolution Imaging camera.
IPC - Imaging Proportional Counter.
SSS - Solid State Spectrometer.
FPCS - Bragg Focal Plane Crystal Spectrometer.
MPC - Monitor Proportional Counter.
BBFS - Broad Band Filter Spectrometer.
OGS - Objective Grating Spectrometer.

Note that a Chinese X-ray space observatory launched in 2024 is named the Einstein Probe.
