When astronauts are selected for training, space agencies don’t only look for qualified people who have the skills they need. They also look for certain personality types, who are suited to demanding environments. One important factor is the degree to which astronauts will follow orders given by ground control — because astronauts need to be independent enough to act on their own in certain situations, but they also need to be willing to follow the instructions given.
In 1973, the three-man crew of the Skylab mission went on strike for a day, cutting off communication with ground control. They complained that they had been worked too hard, with work days of up to 16 hours, so they decided to spend the day relaxing. “We would never work 16 hours a day for 84 straight days on the ground, and we should not be expected to do it here in space,” Skylab 4 Commander Jerry Carr said to NASA ground control, before beginning the 24-hour strike.
