The ASCA Mission
(1993-2000)
ASCA (formerly named Astro-D) was Japan's fourth cosmic X-ray
astronomy mission, and the second for which the United States provided part of
the scientific payload. The satellite was successfully launched on
February 20, 1993. Attitude control was lost on
July 14, 2000 during a geomagnetic storm, after which no
scientific observations were performed. ASCA reentered the atmosphere
on March 2, 2001 after more than 8 years in orbit.
The U.S. ASCA Guest Observer Facility (GOF) is located at NASA's Goddard
Space Flight Center in Greenbelt, Maryland. The GOF is part of the Office
of General Investigator Programs
(OGIP) in the Astrophysics Science Division
(ASD).
The primary responsibility of the U.S. ASCA GOF is to enable U.S.
astronomers to make the best use of the ASCA mission, in close
collaboration with the Japanese ASCA team.
