Mission

Kosmos 1667 was the second U.S.S.R. biosatellite mission with a primate payload. Although the American experiment on the Kosmos 1667 mission was meant to be a repeat of the Kosmos 1514 cardiovascular experiment, several improvements were implemented on this mission. Modified post-surgery animal handling procedures minimised the risk of damaging the transducer implants. Data was sampled and recorded more frequently during the inflight period. Two

s with flight-type cardiovascular instrumentation were studied in a ground-based synchronous control experiment; postflight cardiovascular tests were not conducted after Kosmos 1514. Postural tilt tests were conducted during the pre-flight and post-flight periods in several animals to establish a ground-based pool of normal data for this procedure. This data was compared with the similar body fluid shifts thought to occur in flight. Instrument calibration procedures were modified on this mission to ensure that blood pressure measurements would be accurate. The main objective of American participation in the Kosmos 1667 mission was to measure carotid artery pressure and blood flow during the inflight period. The United States provided all flight and ground support instrumentation for this experiment. Raw analogue data from flight and ground control experiments was transferred to the Cardiovascular Research Laboratory at the
