Our Extravehicular Mobility Unit (EMU) is the world’s smallest spacecraft. Used by NASA, it has everything that an astronaut needs to survive. With missions to the moon and Mars in the near future, Collins Aerospace’s EMU suit is a trusted and reliable choice for keeping astronauts comfortable and well.
Our suit’s liquid cooling and ventilation under-garment consists of 300 feet of thin tubing that circulates cooling water around the astronaut’s body. The EMU’s outer layer is made of a puncture-resistant material to protect astronauts from micrometeoroids that could be traveling 17,000 miles per hour. Extreme temperature protection in our suit ranges from -250 degrees F to 250 degrees F.
The interior volume of the EMU is about 5.5 cubic feet (0.15 cubic meters) – about the size of a small refrigerator. The EMU weighs approximately 275 lbs. (125 kg) and contains more than 18,000 parts. To date, there have been more than 200 spacewalks from the shuttle or International Space Station in our space suit.
