| More Tests of Soyuz-T - Nov to Dec 1980
More work was in train to test-out Soyuz-T so, after the main Salyut 6 crew left for Earth at the end of Expedition 4, the space station was used again as a host for a Soyuz-T mission. This time the purpose of the test was to prove the ability to carry a crew of three.
Soyuz T-3 carried the first Soviet three-cosmonaut crew since 1971, when three crew had died following an air leak during the return to Earth from Salyut 1 of Soyuz 11 - they were not wearing space suits. Subsequently, Soyuz crews wore suits on the ascent and descent - the extra weight and space penalties meant reducing the crew to two. Soyuz-T's improved performance compared with the old design meant that the change could be reversed. The improvement cam in part through a slight increase in mass, and partly through re-design and miniaturisation, or eleimination of systems.
