  As presented by Hirabayashi et al. (2004) these proceedings, the VSOP-2
mission is currently being planned. Various kinds of developments are being
made for the misson, and here we introduce the large antenna, fast switching
scheme using CMG, low noise receivers, gigabit data transmission, and high data
rate sampling on-board. We are also studying the system configuration of the
VSOP-2 satellite and the orbit appropriate for the expected launch vehicle, the
M-V rocket. VSOP-2 science goals include imaging the accretion disks around the
massive blackholes in the nuclei of the active galaxies, studies of magnetic
field orientation and evolution in jets, and the highest resolution studies of
spectral line masers and mega-masers. Here we describe the design and the
development of the space antenna, high speed sampler, and the satellite system.
