Abstract :
The VSOP Space VLBI mission uses the HALCA spacecraft, launched from Japan in February 1997, in conjunction with ground radio observatories around the world to create a high resolution radio-wavelength imaging facility. We are using this unique facility to observe a complete sample of Pearson-Readhead Survey sources (Pearson and Readhead 1988) at 4.8 GHz, to determine core brightness temperatures and pc-scale jet properties. In addition we are obtaining matched-resolution 15 GHz observations using the VLBA at epochs close in time to the space VLBI observations to investigate the spectral indices of these sources at high resolution.
