Orbital guinea pigs
For the Skylab crews, the work day began at 6:00 a.m. sharp and ended at 8:00 p.m., allowing for two hours of leisure time before bed. After breakfast, the crews would read the orders of the day, which mission control transmitted to an onboard teletype machine. The men spent their days performing experiments, doing routine maintenance tasks, and running medical experiments on each other. They improvised a lot, designing many experiments on the fly. “It was such an interesting thing to turn loose a blob of water to see what you can do with it,” Carr said afterward. In the image above, taken from a television transmission, Kerwin can be seen collecting a blood sample from Conrad.
