June 1965: Vacuum of space

Despite the fact that a considerable number of studies have been carried out on the effects of rapid decompression to high altitudes, there is still very little information and data concerning the actual effects of exposures to extremely low barometric pressures -- that is, to pressure environments approaching the near-vacuum of space. This information is becoming increasingly urgent in view of the current manned space flights, the programmed flights to the surface of the moon, and the need for man to function safely within a pressure suit in space. ... The critical situation confronting an aerospace crew should accidental loss of pressure be experienced dictated the use of physiologically normal animals so that the data collected would be as valid as possible to obtain. Normal, anesthetized dogs were therefore used; 126 animals were rapidly decompressed to absolute pressures of 1 to 2 mm. Hg.
