The satellite ASTRO-D was launched in February 1993:  its name was
changed to ASCA during the first orbit.  This seems to be a tradition:
ASTROs A, B, and C were all renamed in the same way (to Tenma, Hakucho,
and Ginga, respectively).  Perhaps it is referred to as ASTRO-D in
SeeSat circles because it was launched with that name.

Recent calculations predict ASCA's reentry in February 2000 (+/- a
few months), just in time for the launch of ASTRO-E.
