The first part of this book introduces all relevant American and Russian realized extra-terrestrial The Apollo Spacecraft and Lunar Module, the Space Shuttle Orbiter, and the Space Stations; Salyut, Skylab, Mir, as well as the International Space Station. It provides an overview of the architecture and configuration, highlights specific issues concerning the interior layout and compares the spatial and time allocation of human activities. Drawings and diagrams facilitate comparison.
The main part of the book concentrates on the investigation of the relationship between the environment and its users. This method evaluates and summarizes all the selected habitats by means of the human activities in relation to the characteristics of the built environment (Sleep, Hygiene, Food, Work and Leisure). In addition to analyzing the available data, it integrates the astronauts' personal experiences into the evaluation.
The author conducted structured interviews with astronauts with a special focus on human activity. The book confronts the findings from relevant literature and analysis - based on crew transcripts, spacecraft drawings and mission images - with the personal experiences of the the astronauts and cosmonauts. To facilitate orientation and to ease comparison with architectural drawings and diagrams each category was assigned a specific colour. Design directions for each category conclude each chapter.
1) "Three devices were used for collecting and transferring urine: the urine transfer system (UTS), the urine receptacle assembly (URA), and the urine collection and transfer assembly (UCTA). The urine transfer system consisted of a roll-on rubber cuff that was used like a condom with a flexible collection bag. ... In general the URA system "seemed easy and convenient" for the astronauts to use. Reported problems included the astronaut's hands getting covered with urine every time the system was used. There was a constant film of urine on the inside of the cover and the Teflon top, which had to be cleaned with a towel.
2) "In 1991 the astronauts Jan Davis and Mark C. Lee were the first married couple to serve together on a mission (STS-47). No details about their experiences together on orbit have been released by NASA or by the couple themselves. Sex is also possible without a partner. In his book 'Lift off' Michael Collins writes about the advice of a Skylab doctor to masturbate in order to prevent the possibility of getting infected prostate glands. No other reliable reference on this topic has been found."
