==============
Issue number one: Radiation.
Outside our protective magnetic sphere, space is a shooting gallery of solar radiation and cosmic rays that would wreak havoc on our bodies to a level that right now we can only speculate.
And then there’s the 18 months you would spend on Mars, which doesn’t have a magnetosphere and a very thin atmosphere.
Humans have never been exposed to this type of radiation for this long. It’s a problem we’ve never dealt with before, and it’s going to be a huge challenge to overcome.
Number two: Extremely low air pressure.
The Martian atmosphere has only 1% of the air pressure of Earth.
Walking outside on Mars is not that much different from walking on the moon, from a life support systems perspective.
The thin atmosphere is also a nightmare for landing on Mars.
That’s why smaller rovers like Spirit and Opportunity used bizarre air bag systems to land and Curiosity, which was much heavier, had to use a combination of parachutes, thrusters, and a cable system to get there safely.
So SpaceX’s vertical propulsive landing option is probably best for Mars, but this is something that’s never been done up to this point, so it’s hard to know what challenges there are in attempting this with the thinner atmosphere and lower gravity.
Number 3: Perchlorates in the soil
In the Biosphere 2 project, they grew their own food and struggled to have enough for everyone to eat. When they emerged at the end, many were malnourished and emaciated.
In 2008, the Mars Phoenix lander found significant quantities of perchlorate in the Martian soil.
Perchlorates are salt compounds that are often used in rocket propellants and they’re extremely harmful for humans.
They interrupt the thyroid gland and prevent the body from absorbing iodine, which leads to aplastic anemia.
That’s when your bone marrow can’t make new red blood cells. Red blood cells are what carry oxygen through the body. Minor problem.
Or, if aplastic anemia isn’t your thing, you might get agranulocytosis, which prevents your body from making white blood cells.
Chris McKay at the Ames Research Center said that if your backyard had this much perchlorate in the soil, it would be considered a superfund site.
Basically Mars is a giant toxic waste dump.
Number 4: The gravity problem
Mars is smaller than Earth, with gravity only 38% of that you’re used to here. An average 150 pound person on Earth would weigh only 57 pounds on Mars.
We do have some idea of what to expect from long-term zero gravity thanks to astronauts like Scott Kelly and Mikhail Kornienko, who just this year completed a year-long space mission.
Although the record was set in 1995 by Valery Polyakov, who flew on the Mir space station for 437 days.
And last but not least, number 5: The Contamination Problem
We’ve talked in videos about the Fermi Paradox and the Drake Equation in the search for intelligent life in the universe.
Because if life could form twice in one solar system, the potential for life in other solar systems, and intelligent life, becomes very significant.
So one of the biggest problems when it comes to traveling to Mars is that we’re not just bringing ourselves… We’re bringing our microbes.
The second we land on Mars, we have contaminated it.

I wonder how it would have gone if the people were skilled at farming, engineering, medicine, microbiology, and even just basic survival skills!

[@johncronin9540]

Excellent video, and one reason why I think our first ventures beyond low-earth-orbit should be a return to the Moon, which is a whole lot closer, and where it’s easier to “cheat” in terms of handling food issues, medical emergencies, shorter duration missions, with perhaps a gradual extension in the duration of those missions, to compare lunar gravity with microgravity (free fall). If I remember, those astronauts who landed on the Moon preferred the low gravity to no gravity. We could even develop a permanent base. The Earth is three days away, not several months, and communication is almost instantaneous. That means that if there is a problem, Mission Control would be able to help immediately. That would be lacking as a crewed vessel got further and further from Earth, since communication is limited to the speed of light, and there would be periods of a significant delay in awaiting a reply sent back and forth. It would also cause a significant delay in receiving telemetry, which really means that in a crisis (such as an Apollo 13 type failure, the flight crew would really be on their own for long periods of time). That’s important when you look at the sheer number of flight controllers (those in the command center, as well as those supporting the flight controllers in back rooms). It would mean a completely different mindset for both crews (astronauts and ground crew). No manned flight has ever been out of contact for protracted periods of time (the exception being the loss of signal when the Apollo spacecraft would be orbiting above the far side of the Moon). The crew would have to do much more on their own. In terms of landing on Mars, the reason why such exotic methods of landing unmanned probes were used was primarily NASA’s budgetary constraints. While early probes, like Viking, had large budgets (in constant dollars), later interplanetary probes have had much less money to spend, so the engineers had to learn how to build much less expensive probes. Hence the airbags, or the systems shown in the video. A MANNED mission would mean a much larger budget, on man-rated spacecraft. The landing system would probably be like Viking’s or the Lunar Modules, using rockets to slow the descent and land. It’s much more expensive than airbags, but it’s safer. I just don’t see a manned Mars mission in the near future. Considering its much lower budget, it is amazing just how much we have learned from the unmanned missions carried out by NASA, the ESA, the Russian space program, and other space agencies. The two Voyager spacecraft are now leaving the Solar System (giving us valuable data on just what that boundary is like, and will likely outlast the planet Earth, and indeed the Sun, as well.

You cannnot possibly expect such an enormous undertaking to have only positive results the first time it is undertaken... that would be like strapping the crewed vehicle fully loaded to the very first model of a rocket and being shcoked when it exploded in an enormous fireball... This is not science failing and showing the travel to Mars is impossible. It is Science WORKING and helping us to work out the kinks BEFORE anybody is sent to Mars.

They'd still get a lot of the same conditions they'll need to figure out, before trying this on a planet 7 months away. This is all so far outside of anyone's experience that it's downright arrogant to think "Oh, we'll figure out all the challenges before we go".

[@jameswhite1910]

A more fair comparison would be the "Underground City" of Edmonton. Nobody would live on the surface. This is an engineering challenge that can be met with today's technologies. I think we'd want more natural light, but LED technology can fill this void. Grand spaces, LED lighting... The real challenge is growing fast enough to build redundancy in manufacturing. You'd want to know that your neighbors could sell you water if your system broke down. I can see "Water Camps" on Mars as I see current "Oil Camps" in the north: places where a handful of foolhardy young folk can get rich providing a service for the masses.

Mars will be very expensive at first - a lot will need to be shipped over at unthinkable expense, but once the base exists, the goal would be expansion, redundancy and self-reliance. The greatest hurdle I can see is finding a way to make it financially attractive to make the initial investment.

Then when it's all perfected we can do it on Mars or any other reachable location we choose. As for the dust issue, there has to be minds smarter than mine, but a double hulled habitat with an air lock entrance with a positive pressure ventilation/filtration system would be a good starting point. If this method works well enough in the enclosures for asbestos removal and in infectious diseases labs, it should be a good baseline starting point here. Obviously, underground habitats would work best, the problem being carving out a hole in zero g conditions with "some" method that doesn't create bigger problems is the key. When talking about how the biosphere people weren't even talking to one another, and paralleling that to living on Mars, the one factor you neglect to acknowledge is that on Mars if you don't work together, YOU DIE ! That is incentive enough for most people to be socially cordial, don't you think? Plus, this endeavor would have absolutely no room for primadonnas. Not when peoples lives hang in the balance. Taking all this into account, maybe thought should be given to a non civilian mission and use the structure, rank, compliance to orders, chain of command, discipline etc. of the military. Remember, most of our astronauts were military pilots, the mindset is there.......follow orders, complete the mission, overcome, adapt, failure is not an option.

Not impossible, but an enormous challenge. Most mistakes have to be made on Earth before going there.

So the biosphere ended with difficulty. Should experiments always work first time?

[@danielmocsny5066]

That's not the issue. Nobody is saying experiments should never fail. Instead the presenter is saying that before you spend billions of dollars on something like a Mars mission, you'ld like to at least show it has a chance of working. The only thing worse than wasting billions of dollars on a manned Mars mission is wasting that money on a failed mission where everybody dies before they can do all the experiments and collect all the samples you were banking on. Look at SpaceX - each time they blow up a rocket, they inch closer to bankruptcy. And those are unmanned expendable rockets. No organization can withstand unlimited losses. They need a certain number of successes to pay for the losses. The biosphere experiment wasn't a huge risk. When things went wrong, they could break the rules and pump in more air or whatever. After the experiment ended, the University of Arizona continued to do experiments with the facility. But with a Mars mission, if it fails you just threw away a lot of money. You won't be able to salvage anything. In the meantime, you could have spent the same money on a vast number of other things with far higher probability of showing a return. For example, you could spend the same money to educate Americans, so we stop being the stupidest developed country on the planet where 50% of people think evolution is a hoax and Noah's Ark is real.

" Should experiments always work first time?" No, they should work _at least one time_ before attempting to replicate them on a different planet, where not working equals everyone dying.

I dont think its a useful experiment. The people going on there will know that they are still on Earth and that this is a test. They can't 'not' know that. Its a type of bias and people will probably behave differently when traveling to mars that is space, where they would not have any other choice but to accept the situation.

The Biosphere taught us this one critical point: Don't let Pauly Shore be involved with any important project. Bud dee.

[@jackfowler6249]

For the Biosphere project they should have recruited some Navy submarine sailors. Those guys live for months at a time sealed up in a metal tube, and have to make their own air. Plus, how could we have explored all corners of the globe? A globe doesn't have corners.

[@NeverInterpreter]

That ending though

[@treesurgeon2441]

I blame the failure of the biosphere project on Pauly Shore.

"A solar system" is a misnomer. We live in "The Solar System". Other star systems have or will get their own names such as The Alpha Centauri System.

[@DieFlabbergast]

In practice, if we ever do colonise a planet around another star, that star will be referred to as "the Sun." Our sun will be "The Earth's sun." So the new star system will be called a solar system.

[@jonnycollison]

@@DieFlabbergast It'll be up to the residents what they call their star, non?

Like actor Dreyfuss' character in the 1975 Jaws intoning ominously, "we need a bigger boat", when the boat suddenly was head-butted by the mechanistic titled star of the film, as the marine biologist huddled in the cabin below with the captain (Robert Shaw) and the village sheriff (Roy Scheider).

Twenty-seven people have been outside Earth's magnetosphere. Of all the three-crew Apollo missions 8 through 17, only Apollo 9 did not make it to the moon in some capacity.
