Crew Ends 100 Day Mars Simulation in Arctic

Paul server guy writes "According to Wired Science the seven person F-XI LDM crew that has been stationed at the Mars Society's FMARS station has completed their unprecedented 100 day simulation. (Actually 101 days, because for 37 they lived on 'Mars time' adding 39 minutes to each day) According to the mission's remote science principal investigator Chris McKay, of NASA Ames. 'Their pioneering simulation of crew operations on Mars time is by far the best work on this topic ever done. It sets the standard for future Mars mission simulations.'"

OK...

So when do we send people to Mars?

And do we send politicians first?

Only if they don't have a spacesuit on.

Well then

Get your ass to mars.

Its not a simulation

Its a bunch of space nerds wasting their time.

Why?

The gravity is wrong.
The solar radiation is wrong.
The atmospheric pressure is wrong.
The soil chemistry is all wrong.

So what have they proved other than they can sit in a phoney "space base" for 100 days and run around in mickey mouse home made space suits? Nothing.

Re:Its not a simulation

Think of it more as a psychology experiment than a real space experiment. Maybe you won't be so testy then.

Of course, if it were a real psychology experiment, they should have at least lived on Mars time the whole time, and not just for a third of it. Makes you wonder why they stopped using Mars time...

Re:Its not a simulation

TFA said they used Mars time during the 24-hour sunlight, they simply covered their windows from 8am to 8pm. If they used Mars time continuously sunset/sunrise would slowly shift around and would probably really mess up their circadian rhythm.

On a side not you are correct that it was more of a psychology experiment, though that wasn't the extent of their goals. They did things like try to figure out ways to minimize their water usage, etc. Basically anything they could simulate and figure out here on earth they did. Now when NASA says "Ok, how are we going to decrease water usage by 10%" they actually have a very well documented simulation to review through and see what works and what doesn't. Basically before this everything was open to conjecture, now we have tangible information to work with, though not 100% accurate to a real mars mission it is better than nothing.

Re:

Probably because they were getting too far off of the circadian rhythm. After 37 days of adding an extra 39 minutes to the day you're a whole 24 hours behind. I imagine on Mars the human body would adjus

Re:Its not a simulation

Er, sorry I hit send too quick... We stopped the Mars Time experiment when we were one day off of Earth time so that we would not be too far off when the simulation was over.

Re:Its not a simulation

If I think of it as a psychology experiment, I'd get even more testy. Long duration isolation experiments are old hat. Then there is real world experience like crews wintering over in the Antarctic. (Or head over to the US Sub Vets national convention - you'll find guys who have done 100 days submerged by the gross lot.) You have the 'closed loop enviroment/isolation' studies done a decade back by NASA, and you have Biosphere II as an example of how not to do it.
 
Then there are stunts like 'living on Mars time' - which has already been done (by the Spirit and Opportunity control teams). Why would you do that? Why would you want to force your mission clock 'out of sync' with the local solar clock, except as a stunt?
 
The simple fact is, the Devon Island station is nothing more than a PR stunt. Driven by Robert Zubrin's ego it has been a multiyear exercise in re-inventing the wheel. TFA is correct when it says 'Their pioneering simulation of crew operations on Mars time is by far the best work on this topic ever done. It sets the standard for future Mars mission simulations.', but what it doesn't tell you is how abysmally *low* that standard is.

Re:Its not a simulation

You're completely missing the point. It's not about whittling down a pile of celebrities or game show contestants, it's about making sure a group of intelligent people with a common goal of research can exist in the psychological environment they would need to on Mars. Once you've got that major factor nailed down as much as possible, then you can go to the trouble and expense of simulating the other physical variables.

Re:Its not a simulation

So what have they proved other than they can sit in a phoney "space base" for 100 days and run around in mickey mouse home made space suits? Nothing.

The true test would be a closed system here on Earth, with only energy input (from the sun or from a nuclear reactor). See if it can function for two years or whatever the required duration of a mission to Mars is without running out of air, water, or nutrient. It doesn't have to be absolutely sealed like Biosphere 2 -- it could exhaust, just not take in, and it doesn't have to be in the same state at the beginning as the end; resources can be depleted. But THAT's the kind of experiment that we should be running.

It was a simulation

A simultation is doing something as close as possible. NASA went through very similar things about going to the moon, and IIRC, it was done in Texas. Even now, every mission to the ISS, is done in water to simulate low gravity. However, if they really WANT

And now that I've read TFA...

Melissa adds that the extra 39 minutes does make a difference, "[you] feel like [you're] getting more work done."

Wasn't it that the optimal duration of a day for humans is somewhere around 25 or 26 hours?

I always try to maximize my awake time; as Pitr would say, Sleep, she is for the weak.

And now for one truly scary detail:

"We've all become acutely aware of the importance of water conservation, minimizing our garbage output, and generally behaving in a way to minimize our environmental impact."

Why is this scary? Well, consider this:

The crew bakes bread, makes a batch of cheese or yogurt, waters the "crops" (spouts and lettuce they are growing), re-fuels the generator, washes a bit of laundry by hand and prepares home cooked meals to add some spice to the day and the meals.

They're training Fremen!

Re:

Why is it scary that they are training hardy survivors who can overrun even the greatest forces of the Imperial army and can hitch a ride on Shai'Hulud? I mean, that sounds pretty damn cool, where can I sign up?

It must have been hard living in a pre-fab environment never seeing the sun and wearing the same clothes for days. Now they can go back to their mom's basement where the conditions will be at least slightly different from a mars mission.

Why 37 days?

That's how long it took to lose a day. So when do they get that day back?

Ha.

Why all the disappointment?

I can't believe how many people seem to think this was a pointless waste of time. Sure, it's a very limited simulation, but it's a very good proof-of-concept study, and hopefully provided additional data on the psychological stresses that would be placed on a team of astronauts trying to establish an extraterrestrial base. By all means, they should incorporate more variables (true self-sufficiency, extended duration, etc) in future studies, but let's applaud an effort to study the human factors involved in space exploration.

1000 days - Mars Ocean Odyssey

There is a couple currently on a somewhat related venture.. they plan to spend 1000 days at sea in a yacht, completely self sufficient and never touching dry land for the duration.

So far they are on day 121 and have had some 'fun' already - a collision with a freighter for example caused some significant damage which had to be repaired at sea.

The idea obviously is to (kind of) simulate a very long space journey where the crew have only themselves and what they can carry to depend on.

There are a few notable differences though such as the lack of fish to catch in space. ;)

You can follow their journey here..
