The EMU has a number of parts that an astronaut can link together by using only one hand. The different parts are in different sizes. This makes it possible for each astronaut to select the parts that fit correctly.
Wearing the whole EMU can add as much as ninety kilograms to your weight. Yet, the lack of gravity in space means you will not feel the added weight.
SHIRLEY GRIFFITH: You will be wearing equipment that will send medical information back to the NASA control center in Houston, Texas. Doctors will observe your medical condition while you work in space.
You also will wear a device that will collect urine, the body’s liquid waste. You will be working outside the space shuttle for about five hours. This collection device can become very necessary.
STEVE EMBER: You will also wear something called the Liquid Cooling and Ventilation Garment. This piece of clothing is worn next to the skin. It helps keep the body cool by moving water through many small tubes that cover the device. The heat from the sun can reach one-hundred-twenty degrees Celsius in orbit. The material of the space suit helps protect against this heat. The liquid cooling device also works to keep your body from becoming too hot.
SHIRLEY GRIFFITH: You will also put on a container that holds water to drink. A small tube stays near your mouth so you can drink water during your stay in space. A special hat on your head is made of soft cloth. It also carries several communications devices including earphones and microphones. These communication devices will permit you to talk with other astronauts working outside the shuttle and with crew members inside the shuttle. You can also talk with the control center in Houston, Texas.
