Soviet Cosmonauts Take 3(-Hour Spacewalk, Examine Faulty Antenna

April 26, 1991

MOSCOW (AP) _ Two Soviet cosmonauts on Friday went on the fourth spacewalk of their mission to inspect a faulty antenna on a scientific research module of the Mir space station, Tass reported.

Viktor Afanasiev and Musa Manarov spent 3 1/2 hours in space, starting shortly before midnight Thursday, the official news agency said. The antenna is thought to be the cause of docking problems on a cargo spacecraft a month ago.

The cosmonauts installed an experimental thermo-mechanical joint, and later removed it. In the future, such joints will be used to add large modules to the space station.

They also removed samples of structural materials that had been exposed to space for a long time, and re-attached a television camera used in geophysical research, Tass said.
