Abstract

The satellite HALCA that the Institute of Space and Astronautical Science (ISAS) launched in February 1997 became the first space VLBI (Very Long Baseline Interferometry) satellite of the world. Long baselines between HALCA with an 8-in diameter antenna and ground-based radio telescopes have formed a synthesized aperture larger than the diameter of the Earth. Quasars and active galactic nuclei in deep universe have been imaged with extremely fine resolutions.
