Abstract
Written four decades before any American astronaut left the airlock of a Shuttle to work at a space station – and a Russian one at that – these words would prove to be prophetic for what would unfold half a century later, in the first decade of the new millennium.
Many elaborate design studies [of space stations] are based upon fitting together in orbit prefabricated sections. It is fairly certain that these parts cannot be assembled by remote control but will have to be man-handled by crewmen in space suits.

Extra Vehicular Activity (EVA) is work conducted by astronauts outside a spacecraft, as opposed to that conducted inside, which is known as Intra Vehicular Activity (IVA).

A percentile is a statistical measurement where a variable for a population is divided into 100 groups with equal frequency. Hence the ninetieth percentile is the value of a variable such that 90% of the relevant population is below that value. In this case, NASA included information about the human body, its size, posture, movement, surface area, volume, and mass. According to NASA Man-Systems Integration Standards Volume 1, Section 3, Anthropometry and Biomechanics, Revision B, July 1995, NASA STD-3001, these measurements are “limited to the range of personnel considered to be the most likely to be space module crewmembers or visiting personnel.” Assumptions were made that the candidates would be in a good state of health, an average age of forty years, come from wide ethnic and racial backgrounds, and be either male or female. In this case the data reflected an example of a smaller frame female Japanese and a larger frame American male crewmember.
