NASA recently announced that they plan to have astronauts in orbit around Mars within 25 years. Not to be outdone, Elon Musk boldly stated that he could prepare a mission to Mars within 10 years. Musk’s SpaceX plan would transport a hundred people to the red planet. Their mission wouldn’t be to visit Mars but to colonize it. In this episode of Space Time Matt breaks down the challenges that the first humans on Mars would face and how they could overcome them.

noxabellus yeah not those outposts, I mean a place here on Earth where they produce their own food indoor, they dispose of their own "wastes", and maybe let's add the oxygen production underwater challenge, not the "let's have the surface sending us tanks already filled with oxygen :D

@MarcusAseth 7 лет назад

I may be wrong in this but part of me believes that Elon Musk is pushing this Mars thing ahead of times, so the rushing for Mars will make us skip important steps and make the whole thing fail in the beggining, maybe ultimately slowing a Mars colony from happening more than it would have been otherwise? Looking forward to see how it will go, but that's the feeling I have about it :P

@Derekristow 7 лет назад

The thing is, there's very little reason to build something 100% self sustaining here on Earth when just importing materials is so easy. Pushing for Mars gives us the incentive we need to develop those technologies, since they're such a necessary part of the journey and eventual colony. In his presentation Musk mentions that science doesn't advance on its own, people have to go out there and work for it.

@CharlesDourdy 7 лет назад

I think it makes a lot more sense to start with sending more robots to Mars in the short term and then build up infrastructure to send humans later. Rather than sending 100 humans and air and water and food along with construction materials, why not send just the construction materials and robots? I know NASA has "rovers" rolling around taking samples and such which is great I agree. But if the intent is to build structures from the local resources, why not get that phase going? Robots that scoop up dirt and at the very least start the refining process. The more they can pre-build the more available materials there will be for those eventual colonists when they do arrive. Also with the likelihood of our needing to live underground in lava tubes, why not get a head start by sending in rovers to investigate these lava tubes? If the robots are smart enough they could even find weak points in the tubes and either shore up weak ceilings or put in some foam to seal up small cracks in the walls. All with the intended purpose that when people finally get to Mars, they have somewhere to go.

@Jaboody27 7 лет назад

1. There's actually only 1 rover rolling around Mars. It's called Curiosity. 2. I agree robots to harvest resources should be first. Send robots each time with different purposes. Y not? He's got the money. 3. Any humans sent to Mars should be limited and engineers. With the sole purpose of repairing all the damaged bots. Because technologically we just aren't there yet to have self sustaining and repairing bots.

@Bananaplox 7 лет назад

I think sending lots of robots to Mars in the short term will be extremely important for survival, but I definitely think we can do both. The ITS is going to be MASSIVE, 100 tons of cargo to the surface is no joke, the "Spaceship" will be also used as the main infrastructure before inflatable habs are set up. Elon has stated 5-10x cargo flights for every manned flight and that in the beginning the first flights would likely have only a few dozen people. Having humans on the surface ASAP would allow maintenance of the robots and local input/control(15 minute ping is tough and risky) Not to mention the science!

@Bananaplox 7 лет назад

Opportunity is still active ;)

@Jaboody27 7 лет назад

CryptoFox Your right about Opportunity! Damn you Opportunity would u settle down already. I was thinking Pathfinder and the one off Spirit that are inactive. Opportunity is the one that's like over a decade and still inching its way along. Old robot just won't give up. Exactly why we need 100 more harvesting resources ;)

@mattscatterty 7 лет назад

Hey, PBS Spacetime team: Perchlorates! There is one really interesting fundamental problem regarding Martian soil that you did not address! Martian soil contains reactive salts called Perchlorates, which are highly toxic to humans, even at the 0.5%-1% levels found in Martian soil. Skin contact and inhalation can cause burns, and ingestion can cause sickness or death, depending upon the amount ingested. This is another reason that hydroponics would be a good idea for growing crops, because any food grown in the perchlorate-rich soil would be poisonous to humans. There are bacteria on Earth that eat perchlorates and spit out useful things such as oxygen as a waste product, so we could theoretically use these microbes to make safe soil for crops and oxygen for breathing. What are your thoughts on the efficacy, safety and ethical implications of deliberately introducing microbial life from Earth into Martian soil? Either way, perchlorates in fine dust particles will almost inevitably get into suits and habitats, so that's something to be addressed as well...

@Thesamdeman22 7 лет назад

Eat perchlorates and spit out oxygen!? That sounds quite ideal doesn't it!

@mattscatterty 7 лет назад

+Camid Daveron It really does! There are concerns over using earth bacteria to convert to deal with the toxic perchlorates in the Martian soil though! As much as "eating perchlorates and splitting out oxygen as a byproduct" sounds amazing, there is still the ethical concern of deliberately introducing large quantities of Earth microbiology into Martian soil. How could contaminating the soil with Earth bacteria disturb our search for native Martian microbiology? Could these bacteria pose a harm to humans or crops grown in the soil? What are the implications of introducing the "first" microbiology to Mars and potentially giving them an entire planet's worth of resources without any competition?? How could this all effect future terraforming efforts? Are these bacteria a reliable way to remove 100% of the toxic perchlorates from the soil? Etc. Lots of questions!

@feynstein1004 7 лет назад

+Matthew Scatterty That just seems like a stupid excuse for people to get upset. We don't know if Mars even has any life, or if microbes from earth will be able to survive there. Also, you're taking sentient piles of billions of microbes to Mars. How would you prevent some from escaping human habitats and colonizing the entire planet? It's inevitable.

@mattscatterty 7 лет назад

+Feynstein 100 I know it's a discussion that's being had! I mean, if they conclude that there is no current microbial life on Mars, nor any past life of any kind, then it removes one of the potentially problematic factors. As far as if the Earth microbes can survive, they would probably have to be extremophiles or at least genetically modified with DNA from extremophilic organisms to help them withstand the conditions on Mars. Actually, consider scratching that last bit, if they're only meant to be inside the artificial habitats then the environment will be much less extreme and I don't know what difficulties they'd face in thriving on Mars. Either way, even if we don't deliberately bring Earth microbial life, the second we send humans down to the planet, we'll have cultures of microbial life that are at risk of escaping onto the planet's surface. So contamination is a serious matter to consider regardless.

@mattscatterty 7 лет назад

+Feynstein 100 Also, although there are differing definitions of the word "sentient", I don't think microbes would qualify. Though it's obviously a bit of a grey area, I just can't imagine microbes have any real form of subjective experience without a nervous system. But I guess that's a discussion for another time haha.

@karthikeyan020 7 лет назад

+Michi Murgdalena For that Mars would have to be richer. But I think a colony on mars would mean less government control and more freedom and hence it would develop much faster than earth.

@rykehuss3435 7 лет назад

As the colony on Mars grows, a government will arise 100% of the time. You have elected leaders, unions, political parties etc. More freedom would actually mean that it would develop slower and might even be subject to be a complete failure because of internal conflicts. What happens when two groups have freedoms that interfere with eachother? You get a conflict, and if there is no official body to resolve that conflict (like the police, justice system, government etc), sooner or later you end up with violence.

@karthikeyan020 7 лет назад

Rykehuss I think, instead of a government, you would possibly see the corporations themselves do those things and if not done right, might cause several scandals but their main motivation would be making money and innovation. They won't look much into welfare or comfortness of the residents. But more on efficiency. They wouldn't care much about beliefs and feels... They are data driven and scientific which means better for group but not so much for individuals.

@christophergamble9334 7 лет назад

Why did Matt, a physicist, just say centralfugal force and not centripetal force like it actually is?

@pbsspacetime 7 лет назад

The centripetal "center-pointing" force is the force that stops you flying off the centrifuge. It's the force exerted on your feet by the wall of the ring. The centrifugal force is the "fictious" force that feels like a an acceleration outwards. It takes the mathematical form of a force in a rotating reference frame. But a rotating reference frame is non-inertial, which is why it's not technically a real force.

@delawarecop 7 лет назад

"But a rotating reference frame is non-inertial, which is why it's not technically a real force" Kinda like gravity:)

@delawarecop 7 лет назад

What we really need is a society to get along here on earth, where there aren't any rich privileged people, nor any poor starving people - just humans. Then and only then can mankind venture beyond this planet to find suitable habitation - otherwise its merely a futile exercise in expensive exotic travel for the privileged few, at the expense of the lives of fellow humans.

@mikesloan3924 7 лет назад

Yeah i'm thinking along the same lines. The problem i keep coming to, when everyone keeps talking about mars is when you hear phrases such as 'it's hard because of this' or 'it has to be self sustaining' etc. I totally get that you have to sometimes do flashy things like 'people on mars!', or hard things to make true progress, but a huge part of me says that science and manufacturing is advancing at such a rapid rate right now, can't we just 'chill' for just a short while - and really nail down some of the tech, methods and calculations needed. Just for our own solar system the cost's of travel are currently insane if governments don't step in more than they currently do. We can obviously learn alot by planning and then doing these missions but, a robot can work out whats actually out there, with more sensory capabilties and instruments for far cheaper than sending whats essentially a big 70kg bag of water that needs constant feeding, gases, water, entertainment etc. Like Virtual Reality i get that someone needs to go first and take chances, but it's all becoming a bit tiresome for me personally. I'd be more interested in taking all the funding for a mars colony and investing directly into current science efforts on earth, or for some giant space dry-dock type thing in orbit over earth, as a place to launch asteroid mining vessels from perhaps. I suppose my long winded point is that it would be great to just tech up and start with the building blocks first, rather than jumping straight to just having people on mars.

I think that the people of Mars should elect their own Martian Hillary Clinton, who in public tells the voters that she supports securing the Martian border, but in reality she's secretly in favor of unchecked immigration from Earth!

@Dee-jp7ek 7 лет назад

@gustavbabic5004 7 лет назад

Andii Neushul Yeah, tell that to the people of Germany who have recently been murdered, raped, and robbed by the highly civilized Syrian refugees. Isn't it funny how only western countries are required to have open borders, but countries such as China, India, and Mexico keep their borders locked down tight, and do not allow ANYONE to live and work illegally in those countries. If you want to destroy a country, then open borders is the best way to do it.

@Dee-jp7ek 7 лет назад

Gustav Babic Ignorance, prejudice and hate never protect nor progress a society. Being the pinicle of 'freedom' 'justness' and 'opportunity' we should be leading by example. Showing the world our 'generocity' and 'compassion', not turning tail and falling back on all the racism, intolerance, hate and ignorance that has been the actual reality since day 1 of our founding. Its time to grow up, put our money where our mouth is and actually BECOME the nation that we pretend to be.

@gustavbabic5004 7 лет назад

So the only way I cannot be ignorant, prejudiced, or hateful is if I agree to have my country overrun by undocumented immigrants? I'm tired of showing the rest of the world generosity, because in my opinion the rest of the world is populated by irresponsible people who always insist on having more children than what they can afford. Keep flooding the west with illiterate people from alien cultures and you can kiss what little freedom that still remains good bye. I'm not interested in helping you. Fix your own country!

if it came to living underground, i'd forsee it being more akin to a 'red colony' setting, at least superficially. there probably won't be the whole 'this corporation is enslaving everyone' and all that (at least, not at first, because you know, corporations). it would obviously depend on how deep we could dig, but finding bedrock (which in some form exists since there are lava tubes) and essentially carving city squares out of it isn't unthinkable if the proper construction equipment can be hauled up there. i mean think about it: we make basements all the time. with less gravity, you could thin walls a bit to conserve space. get a bunch of backhoes up there, start digging, shore up walls, dig farther, keep shoring up... just like mining! at some depth, it's decided far enough, make floors and walls, make higher floors. kinda like sky scrapers in reverse.

Will mars have its internet connection and will it connect with earth's? Within earth is fast, but between earth and mars would be slower by a significant amount. It takes light like two seconds to start at earth, reach the moon, and bounce back at earth, so it would certainly take much longer if the moon was replaced with mars, making the earth-mars connection get that much more lag compared to a one-planet internet, which is especially notable for (say) action and fighting games like Mario kart or smash bros.

Quantum entangled particles can't carry information on them, so quantum telecommunication is not an option.

@ajaykumarsingh702 7 лет назад

da139114 So we are back to Telegraphs huh. Well, now that you have mentioned it, i think it's possible to create a faster communication system with the help of super computers which will convert the beeps of quantum telegraph instantly into readable messages or video calls.

@XerShadowTail 7 лет назад

There would likely be an internet-like connection between Earth and Mars which uses the bundle protocol (RFC 5050). This is a communication layer designed for long delays and in situations where routing points disappear for awhile. If we do actually land on Mars and have a colony there, this mostly unused protocol would likely start being used. E-Mail would work perfectly fine over the bundle protocol and using PGP you would not need to worry about eavesdropping. Twitter would also work fine for shorter messages. On the Mars end, there would likely be a cache that is used to access the internet to provide content. Think of it as a more up-to-date archive.org, but where the web is made available in snapshots. So if someone on Mars went to look at a web-site and it was not in the cached, there could be an hour or more delay before it gets refreshed for it to be made visible.

@johnrichie7199 7 лет назад

With Morse code when you want a dash, you get a dash 100% of the time. Want a dot, you get a dot 100% of the time. That is useful communication. With quantum entanglement when you want a dash, you have a certain probably that is never 100% to get a dash. Want a dot, you have a probability to get a dot, but it won't always be a dot. So no, you really really can't use quantum entanglement to transmit information faster than the speed of light. Transmitting information faster than the speed of light is not possible.

What would it take to build a "space elevator" on Ceres with a hydraulic system that pumps water into a container in space and then basically "shoot" water onto Mars when Mars and Ceres are closest to each other? Then we would not have to try and populate both planets but rather focus on building up sufficient bodies of water on Mars. Ideally the "ice canon" would just bombard Mars on a regular basis and the ice would end up in Mars atmosphere - assuming we get the angles just right - Is this a preposterous idea?

@stevehuntcpa 7 лет назад

Please help me understand...Mars' atmosphere is 96% CO2 and almost no O2. The proposal mentioned in the video is that we "scrub" the atmosphere of CO2 and top it off with O2 that comes from the less-than-abundant H2O frozen on the surface. 1) Exactly how does that work? And 2) If it's not very hard to scrub the CO2 and replace it with O2 from H2O, why don't we do exactly that on our own planet (where H2O is 71% of earth's surface and where CO2 comprises a mere .04% of the atmosphere--and yet still threatens our very existence)? Also, if we can blanket the red planet with solar panels and create sufficient energy to build and power spinning cities...why are we struggling to get solar energy to spread and work effectively on earth? I feel like there must be some (feasibility? monetary?) challenges to this entire colonize Mars plan that are being overlooked. It seems like it should be much, much simpler to clean up earth's atmosphere and generate renewable energy on earth than to start a colony on Mars, where we ALSO have the challenges of cleaning up the atmosphere and generating energy, in addition to numerous other obstacles. Can you make a video on how we can use all this awesome Mars science and technology to completely clean up and reform earth in half the time it will take us to start a colony on Mars?

@insioni 7 лет назад

man u nailed it. u freakn nailed it. some fail to realise, while we make tech for mars, earth will be dead. Yes we will learn lessons to improve our tech on earth, but what good when its already too late. they think science is pop bang. quick tech-gun shot and boom problem solved. It takes atleast 10-20 years for 'new tech' (which we apparently couldnt have found making it for earth #lol) from inception to widespread implementation, for uh, things that are not half baked. Even if we last (next 2-300 years), the rest of the species will be dead, not that much of it is left anyway.Space exploration is good. its great. But those times are past, or in the far future, not in the present.

@RoberttheWise 7 лет назад

Answers are quite simple: First you misunderstood the CO2 scrubbing proposal. The talk isn't about changing the whole martian atmosphere (as it would evaporate too quickly anyway due to Mars' low gravity and a lack of magnetic field) but about making atmosphere for the enclosed habitats. So you just take martian atmosphere, filter CO2 out, electrolyze water from martian ice to hydrogen and oxigen, mix the oxygen with the noble gases left from the martian atmosphere after removing CO2 to get a 20% oxygen mix, pump all of that into the habitat at one atmosphere pressure, jettison the H2 and CO2. Easy enough for a small habitat, a titanic task for the whole planet. So you don't bother with the planet. Then solar panels on earth: The problem is mainly the organized opposition to solar power from the conventional energy industry. They make it less feasible to have large profitable enterprises built around maintaining solar farms. It really comes down to this: How much does it cost to set up and maintain a solar farm + how much infrastructure has to be built and maintained to bring the solar power to households VS how much does it cost to mine fuel for conventional power plants, maintain the power plants, maintain the existing infrastructure and get rid of the waste. But not so fast: What of those costs is getting subsidized by various governments and what infrastructure builds are being blocked by local activists? And which lobby is pushing what subsidies and fueling which local activists? Yeah, solar power on earth is very much a socioeconomic and not a technological.

@stevehuntcpa 7 лет назад

Robert The Wise Thank you. So, I recognize there are reasons for colonizing Mars other than escaping the changing climate of our own planet. Still, climate change is one reason people have given for wanting to get off earth. (It's the most significant reason in the movie Interstellar.) If climate change became so dangerous and destructive that we couldn't "save earth" its present state, would you agree it would be easier to build these habitats on earth and create the Truman-show-like atmosphere and weather here, rather than on Mars? I think I can get behind your answer as to why solar panels don't work here but they might work to power Mars colonies... as long as socioeconomic factors don't come into play on that planet as well. Talk about a monopoly if there's only ONE way to make power there... if you move there, your utility bill might be YUUUUGE.

Why is loss of bone mass a problem on a planet you intend to stay on? Will the bone mass not be enough for the new gravity? Why is it better to launch a small craft several times with fuel rather than launching a larger craft once?

@failedfishermanBC 7 лет назад

Fuel and the tanks it's stored in also require extra energy to take into orbit.

@InqWiper 7 лет назад

Gagan Baath Yes, I know. But does it take less energy to make 4 small launches than 1 big launch? Or does this have to do with it being cheaper to not spend the time to produce a large launch vehicle?

@failedfishermanBC 7 лет назад

InqWiper The on in orbit is gonna make the trip all the way out to Mars. So you want it to be small and light, right? And getting off the Earth's surface and into orbit requires *a lot* of fuel. So you don't want to have to design the first ship with a massive fuel tank. So instead you put a smaller fuel tank to get it into orbit, then when it gets up there you refuel it with another ship and send it on its way to Mars.

@InqWiper 7 лет назад

Gagan Baath Why could you not have the fuel stages drop off from the main craft? I am getting the feeling you have not thought through my question or your answers properly, no offence.

@failedfishermanBC 7 лет назад

InqWiper Have you bothered to research it? It's a somewhat complex thing to think through. I've been reading about it for a long time so it's not something I'm coming up with on the spot. It can be summed up as "the more fuel you need to carry, the heavier your craft, which means more fuel you need to carry". So there is a limit to how big your craft can get. Test it out with physics, do some calculations, you'll see that I'm right.

Could you just exercise every day for an hour in a spinning building to get the bone building required?

@Jayc5001 6 лет назад

bassisku here's my thing why we even concerned about muscle and bone loss? We only need that level of muscle and bone for Earth, if we're living on Mars obviously we only need Mars level enough to keep us moving on Mars... the reason the bone loss and muscle loss even happens is because it's not being used, on Mars and we get rid of bone obviously because it's not needed we are adapting to our environment and its going to stop at the point where our current muscles are being used to the full.

@animistchannel2983 6 лет назад

bassisku: You could just spin the home/sleeping quarters and get the g-force benefit during meals & sleep. Then you could work in the lower g to make the labor easier. Imagine a big turning cylinder building where you enter in the middle and then go "down"/sideways to your apartment. Another cool thing about mars .4g is because of the way plants circulate water, if you dig out or build a big enough dome, you can grow trees up to 250 meters tall with a canopy 50 meters wide, like a 75 story building :)

@lordgarion514 6 лет назад

jayc5000 You're only partially correct. It's true the bone mass wouldn't be missed much since everything weighs only .38 of what it weighs on Earth, and you fall down a lot slower as well. But bone loss also comes with other health problems and most likely we'd still have those problems on Mars as well.

@anthonybaransky137 4 года назад

The answer is Martian concrete, made from local materials and mixed with water to produce a solid material when cured and that could still be 3D printed with a special mixer/robot machine.

How does the decay of an excitation in the neutron field lead to excitations in the proton, electron, and electron type antineutrino fields?

The human race, like any living thing on Earth, evolved with the presence of the Earth's magnetic field. Mars doesn't have a magnetic field, just the remains of what was once a magnetic field. I wonder, can human life surive without a magnetic field, and if so, are there going to be side effects (metabolism or neural dissorders). And why would we put so much effort in making Mars habitable. We are better off putting more effort in improving our own planet. Don't get me wrong, i love science and physics but this whole "let's make Mars habitable" seems like a trend to me.

This is less about Mars itself and more about proof of concept, If it is possible to colonize mars with limited help from earth then we could also colonize other planets, space stations, or other solar systems. any of these options would need to be almost fully self sustaining and any self sustaining tec would undoubtedly be useful for the home planet as well. Even if you are of the opinion that as long as we have earth we don't need another planet, we might not always have earth. All it would take is 1 crazy person launching a nuclear attack and the majority of Earth could become more inhospitable than Mars. North Korea is definetly making progress and even if we stop them before they make and use weapons of mass destruction, its not like uranium is hard to get being 500 times more common than gold. I agree that it would make more sense for us to take care of our planet but as long as big corporations can buy government policy. it is impossible to have a sustainable environment on Earth.

The fact is that we don't need to colonize other planets as long as Earth is around. And Earth isn't going anywhere for at least a billion year. It's simply stupid to terraform an entire planet like Mars from scratch and wasting all of our precious limited resources. What we need is mining facilities on other planets and asteroids so that Earth will become more resourceful in terms of Mineral and precious ores. We need only working units in space, not colonization. No matter how bad we mess up Earth and pollute it, the Earth will still be better in terms of supporting life than any other ball of rock out in Space.

For the gravity issue: How about wearing a heavy tight suit? If the weight is distributed in a way that the joints carry the equivalent of what they would on earth gravity. Wouldn't that solve the issue? In fact, if a person do not plans to return to earth, the bone mass loss is actually an issue?

There are HUGE problems with colonizing Venus or Mars. The centrifuge city is a great idea for the gravity problems of Mars.

@samthestache8 7 лет назад

Although rotating cities sounds cool, I personally don't find that to be rather feasible. Maybe a better way to solve the gravity issue would be elastic suits that introduce artificial resistance?

Concerning the discussion on bone density, I believe that most mars settlement missions discussed nowadays are meant to be one way trips, in which cases the loss of bone density is a trivial fact, indeed, for astronauts orbiting earth losing bone density is an issue because they then go back to earth where they are subject to earth's gravity, and subject to falling and breaking bones, whereas, for future martians, they would remain only subject to the martian gravity and might indeed not need to have as dense bones as we do here on earth.

Regarding windows and rotating habitats/space stations. Windows are totally unnecessary and perhaps even undesireable on spaceships and rotating habitats. The roof of a rotating habitat could be essentially a large video screen and have the same view as a window, but rotated with the habitat, thus preventing disorientation. This makes shielding easier too. Same applies to a space ship. Just screens and no windows and pick the view you want. We already do this with cars - cameras showing a rear view to aid parking.

That plus the gravity issues tells me that the best place to live in space is to colonize the asteroid belt, mine the rocks, spin them up and live inside. All the resources we need are there and not being in a gravity well means it's a great staging area for exploring the rest of the solar system. Mars' main attractions are mainly romantic.

You're right. However, most asteroids are unspinable because they are rubble piles. A better solution is to use rotating space habitats (space colonies) which give you the right gravity immediately. These habitats are not vehicles, so you can add any mass you need to protect from radiation.

John Weck You may well be right about that.

My idea for 3d printing habitats is using the co2 in the atmosphere. I thought (wait, there is "c" and "o2" in co2) resulted in me coming to an idea, split co2 into c and o2, the o2 used for breathing and the carbon used to make carbon fiber, which can be 3d printed into carbon fiber habitats AND more of spacex's mars vehicle to go to places beyond mars (the Interplanetary Transport System will be mostly made of carbon fiber).

redstoneactive5, except that we can't split the C and O2 from each other without introducing a catalyst. And the catalyst then produces different byproducts. We are unable to just "split" the carbon and oxygen from each other without introducing something else into the equasion. If we could, global warming would not be an issue. Basic chemistry son

Planing to make a model of "Marsian city", is there another physics stuff I should pay attention to not only to Centrifugal force, Super conductive magnetic rails stuff, created gravity from those rails, velocity. Does anyone know, what specific angle the "cities" on those rails has to be lean and what velocity?

A simple alternative to the centrifuge would be to just have the colonists carry extra weight in the form of gear around with them during the day or designated work time to match their weight on earth.
