(A) whom (if anyone) was the first human to actually be asleep (that is to say, presumably inside the lander) - not just a scheduled sleep time - on the Moon? It depends on your definition of sleep. Maybe Buzz Aldrin, curled on the floor of the LM cabin: The best Aldrin managed was a “couple hours of mentally fitful drowsing.” Armstrong simply stayed ...


There are at least two papers by Jack Stuster on an ISS crew conditions study: Behavioral Issues Associated with Isolation and Confinement: Review and Analysis of Astronaut Journals. They anonymize and collect/collate excerpts from crew journals (which I believe the project also pushed astronauts to use...it's been a while since I've read these papers in ...


On the Apollo 7 and Apollo 8 flights the crew slept in rotation, such that there was always at least one waking crew member. There were much complaints about the difficulty of sleeping, and the poor quality of sleep, in such a small craft with other people awake and being generally distracting. I am not sure on which mission the sleep schedule was changed, ...


Other answers have covered specific sleep issues pretty well, but I'd like to point out that space missions aren't quite as strictly scheduled as you might think, not after Skylab 4. During Skylab 4, the workload was so severe, and time so strictly scheduled, that the crew essentially went on strike. They got fed up with being overworked and took a day off,...


This is a frame from a video I shot in the Shuttle Mission Simulator back in the 90s. I was sitting in the commander's seat. The shoebox with the red stripes is supposed to be the launch tower, you can see the ground at the bottom. The simulator window field of view was supposed to be accurate. But although I didn't have a helmet on, I would say yes.


I'm probably going to miss actually answering your question about a procedure for handling oversleeps, if one exists. I think this answer will be worthwhile info on scheduling on the ISS anyway. First, though, the closest thing I could find to a crewmember answering your actual question. This is from NASA/TM-2010-216130, the first of the two Stuster ...


In the ISS, they don't wear blue clothes only : There seems to be a preferation of khaki pants, but there is one in light blue too. Sorry, I found no information about the deep blue jump suits worn on Earth. Another orbit image added by Organic Module: (not even in the shuttle)


Many astronauts have reported difficulty sleeping due to cosmic ray visual phenomena which are often perceived as bright flashes of light even when the eyelids are closed. Buzz Aldrin reported them on Apollo 11 and NASA subsequently developed the ALFMED experiment flown on Apollo 16 and 17 to investigate the phenomenon. It was concluded the flashes were due ...


They're portable cooling units for the spacesuits, as you guess, but they aren't used aboard the spacecraft; instead, the suits are plugged into the spacecraft's environmental systems. They're only used between suiting up and arriving at the launch site, hence they aren't stowed aboard the Soyuz and aren't with the crew at landing time.
