First SpaceX Missions To Mars: 'Dangerous and Probably People Will Die' (arstechnica.com) 412

An anonymous reader quotes a report from Ars Technica: As we get close to the end of September, when Elon Musk has promised to lay bare his plans for colonizing Mars at an international space conference, it seems like the ambitious founder of SpaceX can hardly contain his excitement. In an interview with The Washington Post, Musk gushed, "I'm so tempted to talk more about the details of it. But I have to restrain myself." SpaceX fandom has speculated for years about details of Musk's ideas, which include the Mars Colonial Transporter concept. The Transporter likely consists of a large first stage rocket and an upper stage spacecraft meant to deliver hundreds of people to the surface of Mars during the late 2020s and 2030s. Unlike NASA, which relies on public money and is therefore risk averse when it comes to "loss of crew" requirements for human missions into space, SpaceX appears to be willing to take some risks with the unprecedented exploration to Mars. Those first explorers would understand the perils, just as the pioneers who explored the New World or the poles of Earth did. "Hopefully there's enough people who are like that who are willing to go build the foundation, at great risk, for a Martian city," Musk told Washington Post. "It's dangerous and probably people will die -- and they'll know that." Eventually it will be safe to go to Mars, Musk said, and living there will be comfortable. But this is many years into the future, he acknowledged.

    Nice understatement there fella.

    This isn't like the moon... which is at least theoretically close enough that it is at least technologically feasible to orchestrate a rescue mission to bring people home if things go awry, if such provisions are at least planned for... certainly getting people back to earth safely (or sending more supples up) before they starve to death if food supplies were suddenly lost, for example. Mars is, to put it quite bluntly, a fucking ONE WAY TRIP.

    Until we have the technology to get to mars in a matter of only a few days or less, I predict that every manned mission to mars that we attempt will have a 100% fatality rate. It is suicide to go there... plain and simple.

Those considering this need to completely rethink propulsion and come up with a plan for getting people not only there, but home.... safely and expediently, in time scales measured in hours or a few days at most... not weeks, and certainly not months. Otherwise, any rocket we send them up in may as well be their tomb.

      No, actually, it isn't.

      I read a little bit of obscure history awhile ago. While in the Apollo 11 LEM, one of astronauts accidentally broke the switch they would use to turn on the ascent engine. Fortunately, Buzz was able to cram a pen in there and launch off of the Moon. But Nixon already had his speech prepared--the two astronauts would have died on the Moon and there wasn't a damn thing NASA could have done for them.

        I did explicitly say give the caveat that a second mission would have to be prepared for. My point is that it is technologically possible to implement.

        If something happened on mars, it wouldn't matter how prepared we were here, we wouldn't be able to get any assistance to them remotely expediently enough.

      It's almost impossible to die of space radiation overdose. The galactic cosmic rays can't kill you via a radiation overdose, they're dose rate is much, MUCH too low.

      The only thing with a high enough dose rate is solar particle event. And, in fact, there are very few that are strong enough to kill you (but note, there are winter or thunderstorms that can easily kill you if you're unprotected on Earth). One has occurred, however, in August of 1972, with a dose of about 1 Sievert, but it'd only be that high if your only shielding was a thin space suit ( here's a source for that [bioedonline.org]). If you were inside a capsule or on the surface of Mars (shielded by the yes-still-significant Martian atmosphere), you'd be totally fine. Even 1 Sv not really enough to kill you. You need about 2 Sv to really be in danger of immediate radiation overdose and death. But you could vomit in your spacesuit and suffocate. However, these events are not instantaneous, you'd have a warning and the events occur over a period of an hour or several hours, so you have enough time to get inside or behind a rock or something.

      No, it's nearly impossible to die from acute natural radiation overdose in space.

      You'll survive the trip. The worry is about an increase in occurrence of cancer when you get back. However, in any case, the risk of cancer from living in space is less than being a smoker. Although, given the huge deal we make about the space radiation issue, you wouldn't know it. You'd think you'd die instantly or something, which just isn't true.

      As far as how to deal with it, well Mars' surface has a much lower radiation dose from GCRs and especially solar flares. You're half shielded by the planet itself and secondarily by an average of around 40 grams per square centimeter of CO2 mass, maybe more at lower altitudes. Additionally, just massive amounts of rock or dirt work great. And water is more effective per unit mass.

      On the way to Mars, your best bet is to shorten the trip to 90-100 days as Musk suggests, and perhaps use your supplies (water, food, maybe propellant) to shield you from solar particle events. That'd reduce your transit dose to a manageable amount. And you can also use drugs like Amifostine to avoid some of the radiation effects, especially the effects of acute radiation (we're unsure if Amifostine helps for chronic radiation). But once on the surface of Mars, it's possible to reduce the dosage to arbitrarily low levels.

      But again, these are long-term health effects, perhaps like you'd see in any kind of hazardous environment. But you'll be able to perform the mission just fine.

      I was just reading a book on the Vikings this afternoon and happened to read the chapters on the settlement of Iceland and Greenland and thinking about space exploration.

      Compared to even Norway, Iceland was a lot like Mars. Totally hostile climate, vast stretches of it totally unsuitable for human habitation. Extremely long voyage to get there in an environment -- the North Sea -- that's sure death if anything goes wrong.

      Many died trying anyway, and not just all at once. It took several attempts by people who knew that previous ones had failed, fatally, to establish permanent settlements. And the ones that did fail failed for the same reasons Mars is risky -- we bring the wrong stuff and not enough of the right stuff, the climate is hostile, it's far away so you can't easily go back, and sometimes your fellow colonists turn on you and you slaughter each other *and then* die of starvation.

      In many ways, at least as far as we know, the one thing we don't have to worry about on Mars is having to fight our way through hostile natives. Not only did previous migrants face long voyages to uncertain destinations, there was also the likelihood they would have to go to war with whoever they ran into -- hey, let's embark on a trip that's likely fatal simply in the conveyance we have available, to a place we might not have the knowledge or stuff to survive in, and let's do it to steal stuff from people who will fight us to the death to stop us.

      Yet humans have been doing it for millennia, despite the risks and the repeated failures. It's part of what makes us human. If that wasn't part of our humanity, we'd still be eating mangoes and dipping sticks into anthills on the edge of the forest and the savanna.

        Not remotely close. In the worst of conditions in Iceland, I could walk around for minutes totally naked in the worst conditions, go back inside, dink some hot cocoa and be ready to do it again in a few hours. Mars, you'll be unconscious in 12 seconds if you space suit springs a leak and dead in 4 minutes. Iceland wait a few hours until the storm goes away, put on a heavy coat and spend a day out ice fishing. Mars, pour some hot water onto you freeze dried lasagna while looking out the window.

    Musk has said that mankind's long term future lies in colonizing the solar system. Setting up a doomed-to-fail Mars experiment is a good way to discourage people to do that : he's too smart for that.

    Expect a first phase consisting of several supply rockets with prefabs, equipment and tools. Expect a degree of heavy duty robotics to help with fabrication. Expect a *lot* of solar panels, plus of course Tesla battery packs... Most of this SpaceX could do today, with the exception maybe the heavy robotics that might be needed. Maybe we could use Waldo's instead.

    The real challenge, as you point out, will be if we want to return. Ideally we would need Mars to provide the fuel for that, but we would still need to lift all the processing equipment there in order to prepare it.

    But let's be honest: so far Musk has shown a *much* better rate of learning than any nation-state space program. Who would you bet on to get there first?

    In one of his stories - and I can't remember which - Heinlein discussed an engineer project whose budget was complete with an estimate of the number of people who would be killed in its achievement. His project manager comments that this item isn't included in the public budget, for political reasons! This realistic assessment of the tendency for death to occur was very thought provoking; we SHOULD be honest about risk - instead terrorism is treated as disproportionately terrible, whilst antibiotic resistance, which is vastly more seriously, is labelled as potentially dangerous as terrorism to get people's attention.
