Space VLBI History
A series of pioneering experiments involving NASA Tracking and Data
Relay Satellite System (TDRSS) satellites
Levy et al. 1986, Linfield
et al. 1989,
provided the initial proof of concept for Space
VLBI. These initial tests were successfully followed up by the
Japanese-launched HALCA satellite mission (VLBI Space Observing
Programme; VSOP-1, 1997-2006; see
Hirabayashi et al. 1998). VSOP-1
was an engineering mission from the Japanese MUSES (Mu-Series
Engineering Satellite) program that solved a variety of complex issues
involving ground telescope scheduling, data correlation, and Space
VLBI imaging to create a fully functional observatory that was
ultimately made available to the astronomical community.
Following from the operational success of VSOP-1, a proposed US-led
successor mission called ARISE (Ulvestad 1999--New Astronomy Reviews, 43, 531;
Ulvestad 2000--Advances in Spae Research, 26, 735) was recommended
by the year-2000 Astronomy and Astrophysics Survey committee.
While costs precluded such a mission in the tight fiscal environment
of the last decade, 7 of 9
ARISE science goals can be realized
through the SAMURAI science investigation,
while the other two can be realized through the non-SAMURAI parts of
the VSOP-2 mission.
