Essay / Research Paper Abstract
An 8 page paper discussing the components of this highly advanced piece of space equipment. The astronaut’s proximal point of survival during extravehicular activities in space, the extravehicular space suit (ESS) has steadily evolved over the years to the form in which it exists today. The ESS is the complete unit, but it is comprised of several critical, nonnegotiable components. There is no degree of hierarchy outside of the primary life support system; all components are of equal importance to the astronaut when performing extravehicular activities. Life support, communications and protection for the astronauts can be considered to have been perfected. The future direction of ESS evolution likely will be that of reducing bulk and increasing mobility. Includes an appendix of Internet sources of diagrams and photographs. The MLA-style bibliography lists 11 sources and 23 footnotes.

of survival during extravehicular activities in space, the extravehicular space suit (ESS) has steadily evolved over the years to the form in which it exists today. The ESS is
the complete unit, but it is comprised of several critical, nonnegotiable components. There is no degree of hierarchy outside of the primary life support system; all components are of
equal importance to the astronaut when performing extravehicular activities.1 Life Support System The Primary Life Support Subsystem (PLSS) is attached to the ESS
on the upper back, giving it the appearance of a backpack.2 This life support system provides oxygen for breathing; controls the pressure of the suit; provides thermal control; removes
humidity, carbon dioxide and other substances from recirculating oxygen; provides communications with other crewmembers; and monitors conditions within the suit.3 Included in the
covering of the PLSS are water and oxygen bottles, a sublimator and fans to accomplish recirculation of oxygen and removal of breathing humidity within the suit. The case also
contains other items necessary for the PLSS to accomplish those tasks listed above. Ventilation airflow enters from the PLSS at the back top
of the helmet, where it flows down over the face and down through the suit.4 Outlets at the elbows and near the feet serve as ventilation airflow returns, where
there are ventilation garments containing liquid cooling for breathing air and filters to remove carbon dioxide. Retained oxygen moves through a flow sensor, returning to the inlet at the
back of the suit. The PLSS adds oxygen when necessary. In extravehicular activity, pressure is maintained at 4.3 psid.5 Body Parts Gloves
