We report results of a VSOP ( VLBI Space Observatory Programme ) observation of a high redshift quasar PKS 2215+020 ( z = 3.57 ) .
The \sim 1 milliarcsecond resolution image of the quasar reveals a prominent ‘ core-jet ’ structure on linear scales from 5 h ^ { -1 } to 300 h ^ { -1 } pc ( H _ { \circ } = 100 h km s ^ { -1 } Mpc ^ { -1 } ) .
The brightness temperatures and sizes of bright features identified in the jet are consistent with emission from relativistic shocks dominated by adiabatic energy losses .
The jet is powered by the central black hole with estimated mass of \sim 4 \times 10 ^ { 9 } { M } _ { { } _ { \mathord { \odot } } } .
Comparisons with VLA and ROSAT observations indicate a possible presence of an extended radio/X–ray halo surrounding 2215+020 .
