As the other major spacefaring nation, the is a subject of interest to the American people and Congress in their deliberations concerning the future of U.S. space activities. In the course of an assessment of Civilian Space Stations, the Office of Technology Assessment (OTA) has undertaken a study of the presence of Soviets in space and their Salyut space stations, in order to provide Congress with an informed view of Soviet capabilities and intentions. The major element in this technical memorandum was a workshop held at OTA in December 1982: it was the first occasion when a significant number of experts in this area of Soviet space activities had met for extended unclassified discussion. As a result of the workshop, OTA prepared this technical memorandum, “Salyut: Soviet Steps Toward Permanent Human Presence in Space. ” It has been reviewed extensively by workshop participants and others familiar with Soviet space activities. Also in December 1982, OTA wrote to the U. S. S. R.’s Ambassador to the Anatoliy Dobrynin, requesting any information concerning present and future Soviet space activities that the Soviet Union judged could be of value to the OTA assess- ment of civilian space stations. The result of this request is appendix A of this technical memorandum: “The Soviet Salyut Space Program: , , Support, and Training Facilities” is an official summary of Salyut space station activities, pro- vided to OTA by Dr. Balayan, Vice-Chairman of the Intercosmos Council of the U. S. S. R. ’s Academy of Sciences. OTA appreciates the cooperation of Ambassador Dobrynin and the Soviet Academy in providing this information. This appendix is of particular interest in that such information is seldom provided to American agencies through official Soviet channels. Appendix B is a paper prepared for OTA by Geoffrey E. Perry, head of the Ketter- ing Group in England. This paper, “Soviet Space Stations: Achievements, Trends, and Outlook, ” provides an independent view of Soviet accomplishments in this area; it is based, in part, on the Kettering Group’s long-term monitoring of audio communica- tions between the Salyuts and Soviet ground stations. Those individuals acknowledged in appendix C provided information during the course of the study and/or reviewed the draft report.

Voskhod

In and , the Soviet Union launched the 6-tonne Voskhod (“Sunrise”), a modified Vostok capable of carrying two or three cosmonauts on daylong flights. Because the Voskhod was used only for these two flights, some Western experts believe it was intended primari- ly to preempt the U.S. Gemini program, which would put two astronauts in one vehicle, one of whom would “walk” in space. Voskhod had ap- proximately the same pressurized volume as did Vostok, but more volume was made available for habitable crew space because the ejection seat and rails were removed and because the crew wore overalls instead of bulky pressurized space suits. Voskhod 1, weighing 5.3 tonnes, had a three- person crew. In , which weighed 5.7 tonnes, one of the crew couches was replaced with an inflatable airlock and associated hatches to allow for (EVA), or “space- walking. ” During the flight one of the crew ac- complished the first spacewalk of some 10 minutes duration. * * The Voskhod program included the first flight of a physician to conduct in situ obser- vations; it also tested new TV and audio commu- nications equipment, evaluated techniques for These simultaneous flights not only served as spacecraft orientation, and employed a new solid- tests of ground control and launch turnaround , soft-landing system.

Crewmen on Station Aboard Salyut 7 28 used a new computer-controlled 300-lb materials- processing furnace to produce several pounds of semiconductor monocrystals. This furnace oper- ates automatically when the station is unoccupied. New systems for medical examination and diag- nosis have improved the range of biomedical parameters that can be monitored, either onboard by the cosmonauts or remotely from the ground. For example, a thorough electrocardiogram can be obtained automatically. Measurements of blood circulation in the cerebral cortex, an im- portant parameter in near-weightless conditions, are receiving particular attention. Performing about 300 experiments, the station’s first long-term crew worked to meet orders from 500 national economic and scientific centers.
