Next Generation Space VLBI Project: VSOP-2.

The second space VLBI Project (VSOP-2) was approved, and just started construction of the satellite ASTRO-G in the Institute of Space and Astronautical Science (ISAS). Discussion for worldwide collaboration has also been started. Its key science targets are to investigate physical phenomena around massive black holes with its superb spatial resolutions up to 40 micro arc seconds. By the dual polarization capability at all the three observing frequencies of 8, 22, and 43 GHz, VSOP-2 is anticipated to be a powerful tool to investigate structure of accretion disk and the magnetic field structure in AGN jets to see the acceleration and collimation mechanisms.
