Space Suits

Space Systems’ Extravehicular Mobility Unit (EMU), or space suit, that NASA uses is the world’s smallest spacecraft, with everything an astronaut needs to stay alive: oxygen, water, temperature control and CO2 regulation. 

We use 18,000 parts to protect astronauts from the harsh environment of space, including a puncture-resistant outer layer to protect from micrometeroids traveling at 17,000 miles per hour.  To control temperature fluctuations ranging from -250 degrees F to +250 degrees F every 90 minutes, we provide a liquid cooling and ventilation garment under the suit that consists of 300 feet of thin tubing that circulates cooling water around the body.
