Volk was a glimpse of things which might have been: he was a Buran programme program pilot being flown in space to prove he would be able to pilot Buran back to Earth after an extended stay in space. The crew of Soyuz T-12 (callsign Pamir), the second Visiting Expedition to visit the Mayaks, included veteran cosmonaut Vladimir Dzhanibekov, Buran shuttle program cosmonaut Igor Volk, and Svetlana Savitskaya. On July 25 Dzhanibekov and Savitskaya performed a 3 hr, 30 min EVA (Savitskaya became the first woman ever to perform EVA), during which they tested the URI multipurpose tool. They cut, welded, soldered, and coated metal samples. During the Pamirs’ stay, the six cosmonauts aboard Salyut 7 also conducted Rezonans tests and collected station air samples.
