All the electrical power needed for a walk in space is provided by this piece of equipment. It's even rechargeable. Thanks to this piece of the EMU, no astronaut ever has to be late for dinner. The sewn-in wristwatch and pieces which hold on to small tools make this a real handy piece of equipment. In order for an astronaut to talk to mission control, this part of the spacesuit must fit just like a cap.
Astronauts become very thirsty while working in space.
This part of their EMU holds water and has a straw so they can grab a quick drink. Though it looks silly, this part of the EMU is needed to keep the astronauts cool. It fits the astronaut like a new pair of pajamas. Most astronauts have very hard heads. Without this part of the EMU, though, their hair could be messed up by asteroids blowing by.
