Could You REALLY Survive A Trip To Mars? | Answers With Joe

[@joescott]

So, it has been pointed out - like, hundreds of times - that the image of Mars used in the first couple of minutes is actually the moon and not Mars. This was not some deep symbolism or a prank, it was an honest mistake. Probably a misnamed image file that I just didn't notice. Apologies for any confusion.

@@cacogenicist how so? I mean if you count Mars itself. But the Mars atmosphere is so thin it’s what we here on earth would consider low earth orbit or space.

[@cacogenicist]

@@jbirdmax - Densest parts of Mars' atmosphere are like being about 35km up on Earth -- not 200+ km. You can't make methane out of atmosphere and water at LEO. You can on the surface of Mars. It's a very thin atmosphere, but not insignificant. Descent to the surface of Mars from orbit requires thermal shielding. Etc. _" ... IS being in space ..."_ is not correct.

[@jbirdmax]

If that atmosphere were identical in composition to that of earth, could you stand on the lowest elevation of Mars (where the highest pressure is) and breathe the Martian air?

[@jbirdmax]

When I was in the US Marine Corp, in the late 80s we went (with about 25 civilians) to Mt Everest. Mt. Everest is roughly 8.55 Km above MSL (sea level). You need H20 tanks to breath up there as the atmospheric pressure is roughly 1/4 that at MSL and drops of quickly above that. You’re talking about an atmosphere with a density 1/20th that on earth. This is what we would consider “space” as there is little PPM Atmosphere.

Hello Joe - I simply love this video. I have been thinking the same for... decades. But you should also talk about the **psychological** issues !

If you're spinning the compartment won't that cause some problems with the water jacket? Plus water weighs A LOT one cubic meter weighs a ton.

Captain Jack not if you used rigid containers to hold the water. Or better still, build a free-floating, not spinning, shell inside which the crew compartment is mounted on an axle and spun.

“Packing for Mars” is also a really good book by Mary Roach. We should preposition supplies on Mars and make sure they got there OK before trying to send people (for which hopefully we won’t be using the bouncy ball method)

[@jeffbenton6183]

neither the bouncy ball method nor the sky crane method is viable for loads significantly greater than 1 metric ton. Any human-capable lander will use the "supersonic retropropulsion" method that the SpaceX Falcon 9 booster stage uses to return to earth.

[@imEden0]

@@jeffbenton6183 maybe with parachute assistance, but once they’re cut the people are landing with retro rockets.

[@jeffbenton6183]

@@imEden0 The problem with parachutes is that Mars has 1% of the atmosphere of Earth. At the *surface* the atmospheric thickness is comparable to Earth's exosphere. "...parachute assistance... once cut... landing with retro-rockets." is an accurate description of how every lander or rover probe has already landed at Mars. (Even Pathfinder which used "the bouncy ball method" also had at least one retro-rocket stage). For payloads smaller than 1 tonne, that's fine. For payloads that are between 40 - 100 tonnes, as will be required to land and accommodate humans, any use of 'chutes are a no-go. For parachutes to be of any help at all, they'd be far too large to be practical. They'll only serve to add unnecessary cost, mass and complexity. That's why Mars is considered one of the hardest landings in the Solar System: 'just enough atmosphere to cause problems, not enough to help. In other words, there's just enough air resistance to burn up your spacecraft, but not enough to slow it down for a hard landing. Anyways, all that is just what folks at NASA have written in various whitepapers (If I remember 'em correctly - it's been years since I last read one of those things). By the way, some of those reports are even older than the existence of SpaceX. IIRC, one paper insisting on the need to rely exclusively on retrorockets (and a reentry shield, of course) for crewed missions was published back in the '80s, and even that might not be the oldest one.

My take on Mars mission: A) Time, one launch window every two years. That means very little chance to launch, as well as going over delays and issues. It would take over a decade at the very least to build the base and have it ready. Bearing in mind that’s only 5 launch windows. B) Cost, how much do you reckon it would cost to have 10s of launch of robots, parts and materials shipped to Mars. That before the mission can even go. Just one budget cut or setback and the project is over. C) What is the point of going to Mars, it’s deadly, toxic and extremely dangerous. Some say “research”, we already have rovers so why do we need to send people. Think of the other places we could send rovers and the advancement in technology we could get from extra funding which would benefit us all in countless ways and have the opportunity to explore moons on the gas giants or tunnels on Mars. We don’t need to send people, people who will sit around, wander a desert, then die of cancer or cardiovascular disease. I just don’t see the reason to go?

The harshest places on Earth (center of the Sahara, center of Antarctica) are much more hospitable than Mars, and I don't see people lining up to go to these places. It would be a very boring and very short life. Yes, the idea of stepping out onto Mars is quite appealing. Doing it in reality, using the technology we currently have... no thanks!

@@antonystringfellow5152 And why do you folks think that everyone has personal comfort as a factor? In a world of billions, you can bet your ass that you can find people willing to go even if meant certain death 5 minutes after they step out of the rocket on Mars. It might not be for you, but don't use your standards for everyone. And we don't have to go to that extreme. There are many people who wouldn't mind living in 3m^2 of space for months, even years. Sure, there are not many of those, but again, in a world of billions, you can bet your ass you can find a couple hundred thousand. Also, there are many people who completely disregard their well being and happiness - they are content by simply working, finishing one task after the other. Sure, they might not be the life of the party and do not fall under the usual category of "normal", but there are probably millions of those people out there. Just content that there is something to do and that they contribute - regardless of the personal cost. The reason you don't see people lining up to go and live in Sahara, or Antarctic (actually, I'd like to go and live on Antarctic - but it is not allowed) is because, unlike Mars, you would not get the supporting project, even if you work your ass off. Martian base would require a lot of work from the individual and no comfort. But there is a purpose to it - and purpose is what drives people to do things. Take a man having all the comfort but take away a purpose, and you've got nothing. Life not worth living. And you can take away every single comfort and source of happiness but have people infused with purpose, and you will succeed. Boring? Short? Who cares? You? Well, there are people who don't care. So the whole argument is completely pointless as it comes from a certain perspective. Mostly hedonistic. Some people just don't care. One version of it you see in war - people who don't care about comfort, or life, and don't find themselves outside of the war, quite content with living on the front until the end, when ever it may come. Again, there are not many of those, but there are such people. So just because it is "No, thanks!" to you, it does not mean that it is "No, thanks!" for every human being on this planet.

I've made a career in the astronomy and cosmology field as well as other related sciences and I gotta be honest, going to Mars anytime soon is a stupid idea. It makes no logical sense whatsoever to even consider going when we haven't even established a permanent base or settlement on the moon. It's easy to picture and fantasize how such an amazing trip would be, and of course many people will be quick to point out that we went to the moon in less than ten years after the idea was conceived by NASA and JFK but the reality is that there's no similarities or caparisons to the level of difficulty a journey to mars will bring. The main big problem(even though the entire trip is going to bring endless problems) is the radiation and the extremely cold/frigid conditions that no place on earth could be compared to, including Antarctica. Unless the martian base was deep(VERY DEEP) underground, the people living on Mars would only be able to go outside of their contained and pressurized building for just one to two hours a day. Any minute longer would increase the risk of cancer which would already be at dangerous levels just from there alone.

I agree AJ - our best idea would be to wait until we can Terra-form Mars first. If Mars had air to breathe & nice rivers of flowing water we would have been there already in the 1980s. Also - the best idea to get to Mars would be to use the ISS as a space vehicle. We'd have to attach rockets to it - supply the fuel & fire it towards Mars with astronauts in it. Why? - because it's the only permanent space base that we have. It could orbit Mars instead of Earth. We could also improve it by adding more shielding from cosmic rays & make it much larger to include extra room for more supplies and anything else that was needed.

For nearly 40 years I have been advocating a form of rocket propulsion that can radically shorten the trip to Mars without requiring much in the way of tech development or cost: solar thermal rocket propulsion. STP uses sunlight to directly heat a propellant , usually hydrogen, and has demonstrated over 1000 seconds Isp. At the annual Space Congress in Cocoa where I presented a paper on the subject back in 85; I was told it would not be developed because "it doesn't cost enough". The solar concentrator can also be used for power using PV for concentrated sunlight which has efficiency over 40% and more than an order of magnitude better specific power than current space solar PV. This allows thermal to be used in a series of perigee thrusts to escape and then switch to electric propulsion. Trip times are faster than nuclear thermal for a very tiny fraction of the cost.

I believe the problem with artificial gravity created by spin is that it would require a very large system with a pretty large radius otherwise , since the artificial « gravity » becomes weaker when you get closer to the center of rotation , when standing up your head would be closer to the center and experience much less « gravity » than your feet unless the distance to the center of rotation is much greater (like 100+ meters) though I guess you could make the tether system longer .

[@benwilms3942]

@@Foxintox good point but I don't think that really impacts the two tethered ships idea. In fact it supports the idea more than a single spinning ship, because the distance you'd require could be achieved by simply having a longer tether. Also, our bodies already kind of work like that anyway, because on earth, your head has more inertia than your feet, and we have pressure suits to mitigate the blood flow racing to the feet.

[@antonystringfellow5152]

The reality is we need to live on the moon in a base for long term science experiments. The use of robotic craft to resupply the moon base would be good practice for stocking supplies on Mars long before people arrive. There was a blog (text) about going to the moon and building a base. There were some very well educated people on that blog. However the details to do a moon base and survive is complicated and average people have no comprehension of the problems. The most important commodity anywhere in space is energy. You need to build, heat, cool, and grow food to name a few. Think about this Portland cement i.e. concrete will not work on the moon or mars; you need an atmosphere and water at room temperature to cure concrete. On the moon blog the experts agreed with my perspective on this but but I am sorry there are people to uneducated to understand the explanations of the science. I have a good science and computer education but there is so much more that is beyond my current level of knowledge. The moon is doable but requires much planning and preparation.

(Galactica is 766m long, 537m wide and 183m high, maybe Elon will build his that big)

@@MostlyPennyCat I believe you misunderstood me when I refer to a "Battlestar Galactica". A "Battlestar Galactica" is a disparaging term for any oversized, over-engineered, and outrageously expensive ship thought (or better said "advertised") to be essential for any manned mission to Mars, see NASA's so called 90 day report from 1989. Such ships have been continuously criticized by Dr. Robert Zubrin for literally 30 years!

i'd rather figure out ways to fix this planet, it was a good one

[@waltermeerschaert]

I would bet that it would be easier to terraform Earth than Mars...

[@CarFreeSegnitz]

If you have the technology to terraform Mars then you already have the technology to fix Earth. You might lack the political will.

@@killcat1971 What is needed as far as earth is a huge decrease in the population. Good luck figuring out how to do that. China is giving that a shot or they are just trying to slow down population growth. They do it in very barbaric ways. Let's say you could achieve a world population decline of 1% a year year over year. Many problems would freeze or start to go away. First problem you would have is a lopsided population with more people being elderly and net takers who don't produce much of anything. Just one of many problems so I don't see population control happening.

The Sun seeing a manned craft going to Mars: "Did I fire six coronal mass ejections or only five? Do you feel lucky? Well, do you punks?" :-)

Yeah, they would likely need to wait for a solar minimum, a huge majority of Americans are totally oblivious to the hazards of my favorite nuclear reactor, recently realized that millions of Americans sport radiation burns from direct exposure with very few aware of what sort of mess we would be in with the next Carrington event, we'll like lose the GPS system and a lot of people couldn't find there way across town without any it anymore.

See? that's why we need to learn how to generate our own magnetic fields . We already know how to do it in a basic way. But for a human to be protected in deep space, we're going to have to do it larger . The earth has it's own magnetic field that protects us, but do you understand how much energy is needed to produce a magnetic field like that? We haven't learned how to do such things at will yet, key word, yet.
