Skylab Medical Experiment Altitude Test

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 provided a baseline for the in-orbit portion of biomedical experiments on Skylab.

[1] One of the benefits of SMEAT was discovering flaws in the urine handling system of Skylab, which allowed the problem to be fixed.

[6] 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 to compare to the orbiting crews in Skylab living in zero-G.
