NASA Television will broadcast the relocation of a
Russian Soyuz spacecraft at the International Space Station
beginning at 4 a.m. EDT Saturday, April 20, from the NASA
Johnson Space Center in Houston. The short 40-minute
relocation flight begins with undocking at about 5 a.m. EDT.

Expedition Four Commander Yury Onufrienko and Flight
Engineers Carl Walz and Dan Bursch will climb aboard the
current Soyuz vehicle for the fly around from the Earth-
facing docking port on the Zarya module to the Pirs docking
compartment. The move is necessary to clear the way for the
arrival of a new Soyuz ferry craft on April 27.

NASA TV is available on GE-2, Transponder 9C, at 85 degrees
West longitude, vertical polarization, with a frequency of
3880 MHz and audio of 6.8 MHz.
