Abstract: The HALCA satellite was launched by ISAS in 1997 as the main element of the VLBI Space Observatory Programme (VSOP). By the fifth anniversary of HALCA's launch, over 700 VSOP observations have been carried out, predominantly, but not exclusively, of the relativistic jets and accretion disks surrounding super-massive black holes in active galactic nuclei (AGN). Objects studied include nearby AGN such as M87, where the high angular resolution corresponds to high linear resolution, out to high redshift (z > 3) quasars. Observations are made at 1.6 GHz (18 cm) and 5 GHz (6 cm). Achievements by VSOP in these five years and future works will be reviewed. The lessons learned by VSOP are also both scientifically and technically important for the planning of the next generation of space-VLBI missions.
