Three months in space

The third Skylab mission lasted from Nov. 16, 1973 until Feb. 8, 1974. The human and subjective aspects of long-term space flight are emphasized. Physiological questions are considered, taking into account the adaptation to zero-G and biological factors. Psychological problems are also investigated, giving attention to adaptation and adjustment, aspects of rest and recreation, and subjective factors and trivia. Working in zero-G was related to interior activities, observations regarding work station design, and extravehicular activity. A description is given of the various on-orbit operations on Skylab.
