Skylab Medical Experiment Altitude Test
Encyclopedia
The Skylab Medical Experiment Altitude Test, or SMEAT, was a 56-day simulation of an American
Skylab
space mission from July 26–September 19, 1972 at NASA
's Manned Spacecraft Center in Houston, Texas
. The astronauts in the test were Bob Crippen, Karol Bobko, and William Thornton
, who simulated space experiments, housekeeping and leisure activities in a hypobaric chamber.
SMEAT's main objective was to evaluate equipment and procedures proposed for use during the Skylab missions. NASA also wanted to obtain a baseline of physiological data for crewmembers confined in a test chamber at to compare to the orbiting crews in Skylab living in zero-G. The crew was subjected to a pressure of bar
and 70% oxygen level. Closed-circuit TV provided views of activities inside the chamber.
