Astronauts Could Get Lazier As Mars Mission Progresses
sciencehabit writes "Imagine life on a spaceship headed to Mars. You and your five crewmates work, exercise, and eat together every day under the glow of fluorescent lights. As the months pass, the sun gets dimmer and communication with Earth gets slower. What does this do to your body? According to an Earth-based experiment in which six volunteers stayed in a windowless 'spaceship' for nearly a year and a half, the monotony, tight living space, and lack of natural light will probably make you sleep more and work less. Space, for all intents and purposes, turns you into a couch potato."
Explains why Riker stopped shaving second season.
I've already done this experiment over 30 times. Its called winter.
It turns you into a Spudnik.
are the best fit to colonize space for sure!
A year and half in simulated mars mission where you know it is a simulation has to be worse. In a real Mars mission, the crew will be know their activities are important: for the excitement to be first on mars, for the knowledge that a serious screw up could them their lives. On a simulated mission, you're just guinea pigs. Staying motivated must very difficult.
This is why the Heart Of Gold is shaped like a running shoe - does all the running FOR you. Outsource everything...
Full spectrum lights are already used for treating depression.
The lack of windows will not be valid - they will be used for observation of external activity (minor repairs, antenna alignments, ...
The big problem with long flights is eyesight - lack of long distance focus causes the eyeball to change shape gradually (known on submarines). Result is near sightedness.
I call mulligan and demand they do a real field test over a simulation.

Are these the astronauts with Alzheimer's? From the other day?
Give them meaningful works that could only be done on space. Else boredom kills.
Too Lazy Didn't Read
Americans are clearly the most experienced, well-trained, and qualified.
Couch Potato.. check.
So, being confined to a small place with no need for physical fitness results in less physical activity? That's quite shocking.
This is my signature. There are many like it, but this one is mine.
Just install more lights.

Sadly enough, I think you're being serious.
This experiment was precisely to test if trained astronauts, in peak physical and mental health, could maintain that over a long period of isolation and lack of earth-like conditions. Unsurprisingly, the answer was "No" for reasons that anyone (at least, anyone living up here in the north, where sun doesn't stay up for more than a couple of hours a day for several months each winter) could have predicted:
Actigraphy revealed that crew sedentariness increased across the mission as evident in decreased waking movement (i.e., hypokinesis) and increased sleep and rest times. Light exposure decreased during the mission. The majority of crewmembers also experienced one or more disturbances of sleep quality, vigilance deficits, or altered sleep–wake periodicity and timing, suggesting inadequate circadian entrainment
To suggest that "The fact that such environment seriously fscks up your physical and mental health is just because they were sloths to begin with. REAL men wouldn't go through such." is just absurd.
Imagine life on a spaceship... You and your five crewmates work, exercise, and eat together every day under the glow of fluorescent lights. As the months pass, the sun gets dimmer...
Did anyone else picture the crew from the original Matrix movie?
People keep researching Mars missions, being two years in space, like this would be a singular even in human history because of the isolation. The fact is, humans have been doing long duration missions for quite some time. Old Nantucket whalers could be at sea for a year or two. US Navy personel on deployed aircraft carriers and submarines are at sea isolated for six months at a time, sometimes more. Old explorers on Cook's ships, Magellan's ships, were at sea for years. This has been done. We know how to do this. You have a tight captain, brutal discipline, keep people busy, and the mission continues. If there is a problem, it may only be that the crew of a presently manned Mars mission might be too small for that, but maybe we need to rethink what that crew would be?
Similarly, for all the talk of why mars, or why colonize space, no one has ever, even the left trying to be diabolical, or the right being religious nutty, ever mentioned the concept of the right to form religious colonies. Like, the pilgrims came to America to form their own fruitcake colony so they could live exactly as they wanted to under god. This gulf between science and religion, at least in the case of colonizing space, need not be so vast. Let's have a government that invests and encourages investment in space, so that, if people do want to have a tax free haven on the moon, or on mars, they can. If they want to have a pledge allegiance to the flag of mars and they think mars was made 6000 years ago, let them. Or, if people want to have a libertine sex colony on the moon, let them. The whole point of expanding into space isn't about commerce, its about, breaking away from a crowded earth that demands rules so we can all get along, in exchange for the promise of a loosely populated place where you can live, like the way you want to.
This is my sig.
I've already hit rock bottom so there will be no surprises.

Example: http://www.vitamindcouncil.org/research-reveals-link-between-low-vitamin-d-and-military-suicide/
"Research published this past week is the first to report that low vitamin D levels are associated with an increased risk for suicide in US military personnel."
Seasonal Affective Disorder is well known to be correlated with low sunlight levels:
http://www.vitamindcouncil.org/health-conditions/mental-health-and-learning-disorders/depression/
So, I can believe blue morning and red evening would help as mentioned in the article, but I would expect that the participants are getting vitamin d deficient too, because the RDAs are generally several times too low (at least in the USA, not sure about Russia).

A 21st century issue: the irony of technologies of abundance in the hands of those still thinking in terms of scarcity.
Aren't there some fairly simple solutions to this "issue"? Provide the spacecraft with more "natural" lighting and give the astronauts earth based work schedule (9-5 job). The article makes these suggestions as well but only in a few sentences in one paragraph out of 10. Astronauts should be deeply involved in adjusting/finalizing the missions survey areas, they can continue training and familiarizing themselves with their equipment and soon to be home. They should have plenty to do on their trip, not laying about waiting for the landing.
That it will take 18 months to get to Mars. I know they're using the rocket model for this but I have to explain:
Rockets expend a vast amount of their energy just getting free of Earth gravity and then use the acceleration to head toward any object but not under power. So they expend the fuel just within the band of the origin.
But there's a little technology that is currently propelling a couple of satellites called ion propulsion. It's not a massive dump of energy but a slow, steady one while acceleration increases. Calculation show a trip to Mars would take about 39 days with ion drive. Granted, the spacecraft would be best built in LEO or above that way no aerodynamic issues have to be taken into account. Essentially you'd have something that looks like the lunar lander used in the Apollo program. Not sleek and graceful but sort of cute ugly.
Astronaughts are not your average joe! At least they weren't initially before we decided to start sending up teachers and the like. Last I knew they don't just take random people, but actually have criteria that must be met first.
fuck off, Dave, just fuck off.

This is not a big deal. Those of us who live in the north country deal with this every year. We have evolved social methods for handling the lack of sunlight. The further north you go the greater the effect. Much like travel to Mars. In a space ship they can do the same sorts of things. One modern solution is as simple as using lights of the proper spectrum and intensity. Widely used. Not a big deal.
Hey, he actually has a healthy sense for it. Sometimes a little shaking up is all you need to resettle in a better local informational equilibrium. Just look at the history of science. That doesn't necessarily imply malice or trolling in the regular sense of the word.

Or just put a hot Canadian chick on the ship, and let the time just fly by. The fist fights alone would not only keep you in shape, but also entertained! Not to mention the unwanted sexual advances! The Drama! Of course it might be a bit awkward by day 2.

Sending droids to Mars is pretty much as lazy as you can get, NASA just needs to buy some La-Z-boys, bar fridge, and some game controllers and pretty much it could like your working out of your parent's basement.
I haven't thought of anything clever to put here, but then again most of you haven't either.
