Explanation:
Looking like a fleet of futuristic starcruisers poised over planet Earth,
NASA's highly successful series of
High Energy Astrophysical Observatory (HEAO) spacecraft
appear above in a vintage illustration.
Labeled A, B, and C in this conceptual picture,
the spacebased telescopes were known as
HEAO-1,
HEAO-2, and
HEAO-3 respectively.
HEAO-1 and HEAO-2 were responsible for revealing to earthlings
the wonders of
the x-ray sky, discovering 1,000s of celestial
sources of high-energy radiation. HEAO-2, also known
as the Einstein
Observatory, was launched near the
date of the famous physicist's 100th birthday (November of 1978)
and was the first large,
fully imaging x-ray telescope in space. HEAO-3, the last in the series,
was launched in 1979 and measured high energy
cosmic-ray particles and gamma-rays.
