This NASA video segment explores the necessity and composition of spacesuits. Viewers first watch a demonstration in which astronaut Jerry Ross places a water balloon, representing a human body and body fluids, into a bell jar. A vacuum pump removes the air from the jar, and the water begins to boil. Ross discusses the connection between this end result and the need for pressurized spacesuits. This video segment discusses how pressurized suits were developed and what the function is of each different layer and part of a spacesuit. The segment shows footage of astronauts in spacesuits from various missions.
