Our Extravehicular Mobility Unit (EMU) is often called the world’s smallest spacecraft. We have worked side-by-side with NASA to evolve and upgrade the equipment to provide today’s astronauts with everything they need to stay alive: oxygen, water, temperature control and CO2 regulation.
- The EMU can protect astronauts in temperatures ranging from -250° F to 250° F (-156° C to 121° C)
- The EMU protects astronauts from micrometeoroids traveling up to 17,000 mph [27,358 km/h]
- The EMU weighs approximately 275 lbs [125 kg] and contains more than 18,000 parts
- To date, there have been nearly 270 spacewalks from the space shuttle or ISS in the EMU
- The longest spacewalk was 8 hours, 29 minutes
- The interior volume of the EMU is about 5.5 cubic feet [0.15 cubic meters] – about the size of a small refrigerator
- The suit’s liquid cooling and ventilation garment under the suit that consists of 300 feet of thin tubing that circulates cooling water around the body
