Mars Space Suit Trials in North Dakota 124
AbsoluteZero writes to tell us Space.com is reporting that a new spacesuit prototype being designed for Mars exploration is currently being tested in North Dakota. From the article: "The Mars spacesuit is the culmination of 14 months of work by faculty and students with the North Dakota Space Grant Consortium, which received $100,000 from NASA to develop the prototype. The local public is invited to view the Mars spacesuit in action on Sat. May 6, weather permitting, at its North Dakota test site."

Mount Washington has hurricane force winds and sub-freezing temperatures _every month of the year_. The highest wind speed over land ever recorded was measured from the summit at 231MPH before the anemometer was destroyed. The number of days of hurricane force winds average 110 days/year. In January, that means every 3 out of 4 days.

Joints (Score:5, Informative)
There is a lot of comment in the Apollo Lunar Surface Journal [nasa.gov] about future planetary space suits. Comments from the moon walkers tend to be that engineers today are trying to solve the wrong problems. People assume that the apollo suits were not mobile enough, in fact they were, but the joints in suits were a maintenance nightmare. So if a future suit is more complex because of this supposed moblity requirement then it will be harder to keep it working for a month on Mars.
TFA doesn't say how they plan to improve mobility. They are only pressurising this suit to 1 PSI, about a quarter of what is required. I would like to see them work on the PLSS system as well. Lunar suits were limited to seven hours outside, but the tanks in the back pack were filled by high pressure tanks in the LM descent stage. If oxygen is to be extracted from water during the mission a lot of energy will have to be put into pressurising the PLSS tanks (to 1000 PSI, more would be better) while on the surface.
One of the limiting factors in EVA time will be electrical power. Energy is going to be needed to heat the hands and feet while outside. If a way can be found to distribute heat between to torso and the extremities while outside then power won't be needed for this. Perhaps a liquid cooled garment can be used to distribute heat to cold parts of the body.
Its good to see people working on this kind of thing. Its a pity that there aren't going to be any rides to mars in the forseeable future.

This raises questions about "ballooning". When a suit is pressurised, it balloons out and soon our intrepid space traveller is walking and looking like the Michelin man. This can of course be solved by making the suit out of hard materials, but probably increases complexity.

The suit's handling of Martian atmospheric pressure can't really be tested in any natural terrestrial environment. I suspect North Dakota probably provides an adequate facsimile of Martian terrain, though (and at a reasonable price).

And that doesn't even address the issue of bone and muscle degeneration which from over a 1 year period in space and a year and a half in reduced gravity will be pretty significant. It's the bones that are the real problem. There are some possible medical treatments that might help, but at the moment, nothing that's going to be able to deal with the problem on that scale. I guess that's one of the disadvantages of being an adaptable species.
We got to the moon because the entire country was focused on it. Let's face it, the general public could really care less about a manned trip to Mars. They certainly don't care as much as they did back in the early Apollo days. And without that sort of public commitment, this just isn't going to happen anytime in the next few decades. NASA has a dwindling budget and the public doesn't really care. You simply can't go to Mars like that and expect to bring the crew home.
I'm all for going to Mars, but I'm also all for bringing the crew back in one piece. Without that, it's simply not worth it.

There's so much research out there [google.com] about this! Even NASA [nsbri.org] - sensibly conservative and cranking up the "danger" to manufacture a mission for the ISS ("Seeing what radiation in space does" as if we don't know from 30+ years of space flight) - isn't as strident as some people who should search before they post.
I guess if the New York Times can get "space radiation" wrong, as they did in 2003, then Slashdot denizens can too, but I foolishly expect more tech-aware people here. Here's the real deal on Mars Mission radiation from the Mars Society [marssociety.org] based on real science, not on half-remembered sci-fi movies.
To the second point, "bone and muscle degeneration", there are two sets of data on this. First, the very real bone and muscle degeneration experienced by long-term Soviet Mir-jockeys, who simply didn't do their exercises, and second, the remarkable amelioration of these "effects" by all long-term US astronauts, who did do their exercises.
I guess we'll have to recruit the Mars crews from the pool of "following the doctor's orders" astronauts rather than the "ignoring sensible medical advice" group.
