 In 50-s "Zvezda" was involved in the USSR space research programs.
There were developed life support and escape systems for test animals (dogs) which were used in high-altitude vertical rocket launches.
In 1959 there were developed a pressure capsule with a life support system for the Laika dog orbital flight, and then pressure capsules and ejection installations for other test animals' orbital flights and landings.
Since 1959 the company got down to design and development of cosmonauts' life support, escape and survival means.
For "Vostok" spacecraft, there was developed the ëð-÷-úá pilot seat, which provided for an emergency escape in an ascent phase and planned ejection before landing. The óë-1 full-pressure space suit, complex of life support systems and survival means provided for cosmonaut safety under any environmental conditions of all flight stages and after landing.
In 1964-65, the company developed a complex to support the first in the mankind history space walk performed by A.Leonov. It included the EVA space suit, portable life support system, soft inflatable airlock chamber.
Further development of space suits and portable life support systems was the equipment developed for A.Yeliseyev and E.Khrunov who performed a transspace walk from "Soyuz-5" to "Soyuz-4" in 1969.
In the frames of the national Lunar research "Zvezda" developed the first full-pressure suits of a semi-rigid type, which were later adapted to operation in the "Salyut" and "Mir" long-term orbiting stations. For the first time these space suits were tested in space by cosmonauts A.Grechko and A.Gubarev, and the fourth space suit modification ("Orlan-M") is still the main means to support all nations cosmonauts' EVAs in the "Mir" OS and is planned to be used in the International Space Station.
In 1990 in the "Mir" OS, cosmonauts A.Serebrov and A.Viktorenko successfully tested in space the 21KC manned maneuvering unit.
