The lower part of the spacesuit is next. It is called the Lower Torso Assembly. It is like putting on a large pair of pants that have boots built in the bottom of the legs.
STEVE EMBER: Next comes the upper part of the spacesuit. It is made of a hard plastic-like material. To put it on, you must hold your arms over your head, and rise up into the upper part of the suit. The upper part of the suit also holds the Primary Life Support System.
The life support system supplies the oxygen needed for breathing and the air pressure necessary to protect your body. The upper part of the spacesuit also carries an emergency oxygen system in case the first system fails.
An important part of your spacesuit is the control module. It lets you observe and control your oxygen system. It is also the place you find the controls for your communications equipment. And, it tells you if you are having a problem with any of the spacesuit’s devices.

SHIRLEY GRIFFITH: NASA scientists are also considering the kind of spacesuits that would be needed for exploration on the planet Mars. Because of the gravity on Mars, spacesuits may have to be designed to be lighter than suits used in orbit or on the moon. The equipment may also have to protect astronauts from dust carried in the winds on Mars. And, they must be easy to repair and keep clean during a longer flight to and from the red planet.
