What To Wear On Mars 122
Roland Piquepaille writes "If men ever land on Mars, what will they wear to protect them from radiation, micrometeors and the very cold climate? Several students from the University of Alberta tackled the problem and designed space suits for Mars. Their prototype suit is composed of twelve layers of materials, including one made from Demron, a new nanotechnology material developed by a Florida-based company, Radiation Shield Technologies. The students and their professor, Dr. Barry Patchett, think their suit will largely be ready before real missions to Mars start in about twenty years. They also hope that NASA will pick their design. More details and references are available in this overview, including some illustrations."

A spacesuit [astronautix.com] is in essence a highly complex, articulate one man spaceship. As such, it takes time to develop and iron out the bugs. The A7L suit [astronautix.com] used on the Apollo missions took nine years to develop, and was, as far as I can understand, a simpler piece of enginering than a suit for Mars will be - for starters, the gravity on the moon are less, meaning that the suit could have more mass without beeing uncomfertable to wear for extended periods of time. Also the moon has no atmosphere, while if you're going to Mars you might want to make sure there is no way the atmosphere on Mars affects your suit in a negative manner.
The EMU (Extravehicular Mobility Unit) [astronautix.com] that was developed for use on the Shuttle faced a simpler problem - no gravity to worry about, no moondust that could get into the joints, no chance of the astronaut stumbling over a rock - yet it took as long as the shuttle to develop the first flightrated variants.
Why indeed start designing the suits ten to twenty years ahead of the mission? Because it takes about that time to get the best possible design worked out, all the bugs ironed out and enought suits manufactured - during the apollo program each astronaut had 3 suits; one for training, one for flights and one backup.
Useless fact; The A7L suit [astronautix.com] had a mass of 22 while the assosiated PLSS (Portable Life Support System) had a mass of 26 kg. The EMU (Extravehicular Mobility Unit) [astronautix.com] used on the US spaceshuttle had a mass of 50 kg and a PLLS weigthing 15 kg.

Part of the problem is the need for a "feature freeze".

In neo-Darwinism, mutations are random with respect to fitness and do not preferentially favour traits that are well suited to an organism's current environment. So humans will not adapt in response to environments with significant radiation, if that is indeed what you are getting at.

- Radiation. Mars has little to no magnetosphere but it does have some atmosphere. This provides some protection that the Moon does not. Also, the Moon is much closer to the sun so the levels of radiation from it are higher. There are also little baby north and south poles [spacedaily.com] around the planet. Landing in one of those will provide a bit more protection.
- Temperature. The Moon [nasa.gov] has much higher and lower temperatures to worry about than Mars [nasa.gov]
- Sandstorms. True, the Moon doesn't have these but with the low gravity, thin atmosphere and fact that they won't be sleeping in hammocks, explorers/settlers should be able to handle them as long as they wear something thicker than a windbreaker.
