The basics of spacesuits

Abstract

Mankind's quest for ever-higher altitudes resulted in finally reaching into space itself. However, the moon, planets and vast expanses of open space present even greater challenges. While space shares demands with high-altitude aviation such as proper oxygen level, removal of carbon dioxide and humidity control, space additionally requires protection from greater thermal extremes, radiation and direct sunlight. In addition, operating in space adds greater challenges to communication, mobility/fit and any operation in which one must use one's hands. Approaches for satisfying these more stringent requirements have varied through the years with varying degrees of success. As experience has been gained, new techniques and technologies have emerged.
