During a manned mission to Mars, human comfort will play a big role in the mission’s success. The current bulky space suit in use weighs in at 300 pounds and is impractical for use in low gravity environments.
Researchers at MIT are working on a spandex and nylon BioSuit to be used in such a situation. The torso would be pressurized to about 30 kPa while the limbs would be sheathed in thinner material allowing for increased dexterity and decreased weight from the current model.
There will be different zones in a settlement with different security requirements for the suit:
Contents
Outdoor Suit
During outdoor work or excursions outside of buildings the astronauts or colonists need a very reliable suit with full life support. It protects from the vacuum and radiation. Depending on the duration of the mission it contains an amount of compressed air for breathing. Telecommunication devices are also useful.
Indoor Suit for Airless Rooms
Most parts of a settlement will not offer any life support, not even air. However, the radiation is significantly lower than outside, allowing less heavier suits. For those rooms a still reliable suit is necessary with protection from vacuum. Air tubes can provide air for breathing and make bottles with compressed air unnecessary.
Indoor Suit for Less Protected Rooms
Some rooms in a settlement may be filled with breathable air, but without highly secured walls, doors and windows. There is danger for a drop in pressure at any time. Light space suits should be enough to provide enough vacuum protection for a couple minutes.
Indoor Suit for Well Protected Rooms
There is still some danger for a drop in pressure. Ultralight suits with the helmet off in regular usage provide a comfortable protection.
