We (for collaborators see acknowledgements) present a preliminary report on VLBI Space Observatory Programme (VSOP) observations of one of the brightest radio sources, PKS 1921-293, at both 1.6 and 5.0 GHz. With the high-resolution provided by HALCA, we are able to look deeper into the core region. An inner jet component about 1.5 mas to the core is revealed for the first time. The core brightness temperature (in the rest frame of the quasar) is estimated of 3.0x10^12 K.
