Ask Bas Lansdorp About Going to Mars, One Way

NASA's been solicited ideas for exploring Mars, but Dutch entrepreneur Bas Lansdorp is already planning a different kind of trip than is likely to come from the U.S. government. Lansdorp's Mars One project has the goal of putting humans on Mars in 2022, with a twist that might dampen many people's hopes to be a Mars-exploring astronaut: the trip Lansdorp plans is one-way only. That means dramatically less fuel on board, because unlike typical Mars voyage plans, there would be no need (or ability) to carry the mechanism or the energy storage to return to Earth. If you (and three close companions) are willing to go be the first people to die on Mars, you'll also need to give up more than a pinch of privacy, because the Mars One plan to obtain the necessary funding is straightforward: create a media spectacle, and monetize it through advertising. (Note: If Elon Musk's optimistic sounding predictions are right, maybe one-way Marstronauts can get a return ticket, after all.) Many questions about the proposed journey are answered in the project's FAQ; check there before formulating questions. Ask Lansdorp about the practicalities and impracticalities of reaching Mars with as many questions as you'd like, but (lest ye be modded down) please only one question per post.

    This question may boil down to cultural differences but I'm an American, fairly non-nomadic and I have a lot of cargo -- both mentally and physically. There are places of my youth that I may never return to and I currently sit a thousand miles away from. But I'm okay with this because if I flipped out one day I could just board a plane or road trip it back. I'm aware that settlers who came to the Americas faced similar issues but they were moving to a new land that was already inhabited by humans and had new places to offer them. Mars ain't the kind of place to raise your kids. In fact, it's cold as hell. I would surmise that someone would need to be legally insane to willingly go to a place without society, without parks, without schools, without culture, without even atmosphere, without children, without the elderly and without the prospect of seeing those things first hand again. Furthermore, should a sane person make such a decision I can see no perceivable way they would remain sane. Even if the person is nomadic or adventurous in nature, you will bring them to a new world and require four of them to remain cooped up in a thousand cubic meters.

I know your ratings go up but what happens when all your reality television is 90% insane ramblings of home?

      Mixing manned missions and supply missions might help too. You can pack a lot of supplies of you don't have to keep people alive in space 2 years. if they were really clever, they would launch supply and robot scouting missions first so the settlers had plenty of equipment on the ground when they got there.

      Have you asked anyone who was nearly asphyxiated about the brevity and painlessness of their experience, and the extent to which they were aware of it? Consciousness and discomfort will persist a lot longer than 10 seconds. The near vacuum outside your skin on Mars is essentially irrelevant, and would greatly diminish the effect of the low temperature.

      Here's a quick experiment you can do at home (but don't overdo it, obviously). Breathe out fully, and don't breathe in again for a while. Even without any special preparation, a fit person can hold out longer than 10 seconds before having to breathe in again, with their consciousness quite intact. I can easily get well past 10 seconds and I'm mid-50ish and not particularly athletic.

      The GP is correct, in a vacuum you'll be out in 10-15 seconds. So we are told in our aircraft safety seminars. (We have a research plane that gets to ~ 50,000 feet.) And that's why the nice flight attendants tell you to put on your mask first in case of loss of pressurization. If you try to help someone else first and don't immediately succeed, you'll both faint. And die.
      Losing consciousness from lack of O2 while continuing to breathe is quite different then being prevented from breathing. Increasing CO2 in the blood is what causes the desperation for air. As long as that is being exhaled there isn't any panic and you'll quietly pass out from lack of oxygen. It happens frequently when somebody goes into a sewer for instance, where the oxygen has been consumed. After a few moments, they simply pass out. Many years ago I watched a science program where the host, with a mask, breathed his own exhaled air, only the CO2 was chemically scrubbed out, as he wrote what he was experiencing. As his available oxygen diminished, his writing became sloppy, but he expressed (and showed) no signs of distress as he sagged, wobbled in his chair, and started to slump before the folks came in with the oxygen to revive him.

  25. Space for growing food? by Mr.+Theorem · · Score: 5, Interesting

    Your FAQ, in the "sustainability" question, states

    The first four will also be carrying a device similar to a portable greenhouse, that will allow them to grow their own food.

    If we take 2000 calories per day as a baseline human need, that's 730,000 calories per [Earth] year, or about 3 million calories per Earth year per four-person crew, and the total need will grow by 3 million calories per Earth year every two years as more missions arrive. The diet would need to be varied, both to guard against catastrophic crop failure and to provide an appropriate spectrum of nutrients, and a reasonable estimate (e.g. based on a combination of corn, beans, and squash) suggests that 1 acre on Earth can provide such 3 million calories. But Mars gets, on average, only about 44% of the insolation as Earth does, so the first-order estimate suggests you'd need about 2.3 acres per mission-load of astronauts to grow a subsistence diet. This presumes that radiation won't negatively impact the crops, that the yield throughout the Mars growing season scales comparable to the Earth's, that your soil is comparable to Earth's, and many more things. You'll also need enough additional carbon and water to make the non-edible parts of the plants and soil, and you'll need to make sure there exists a suitable microbial community to decompose crop waste and turn it back into a useable food-growing medium (i.e. compost).

    I don't see in your concept drawing anything that approaches the size of land that would be needed to come anywhere close to such sustainable food production. Do you even have a back-of-the-envelope plan for sustainable food production, or is the bulk of the astronauts' calories going to need to come in perpetuity from the Earth?

  27. False analogies by JDG1980 · · Score: 4, Insightful

    Every time manned space exploration is discussed on Slashdot, we usually see false analogies to the Age of Exploration on Earth. These analogies are false because they fail to account for the vast, vast difference between traveling to a foreign (but inhabitable and, in fact, already inhabited) continent on Earth, and traveling to a hostile desert in outer space.

    Christopher Columbus made not one trip to the New World, but four. It wasn't a one-way journey and he didn't die there; he died back in Spain, a successful and wealthy man. People who went to the New World didn't do it for shits and giggles; they did it because they calculated they could be more successful there, because they thought they would be freer in America than in Europe, or in some cases because they were expelled there as convicted criminals (this latter instance was even more common with Australia). And for the most part these were rational beliefs; America had a lot of good land available, while in Europe it was mostly in the hands of a few wealthy aristocrats. (And in an agrarian society where most of the population consisted of farmers, this was a big deal.) There were plenty of natural resources in America, and once the first communities got settled, people could have a decent life there for themselves and their children. It was far enough from Europe that the European countries couldn't meddle too deeply into local affairs, but near enough that there could be an import/export trade, communication, and a return to the homeland if need be.

    The same was true of America's Western frontier expansion - yes, there was an ideological element (Manifest Destiny) but the average pioneer did so because they thought they could better make their fortune out West, either by homesteading land or by prospecting for valuable minerals. And again, the land was livable and the native people had in fact been living there for thousands of years already.

    None of this applies to a mission to Mars. There is literally nothing for us out there. It's a vast desert worse than any on Earth - at least in the Sahara you can breathe. How could anyone plausibly think that going to Mars would mean greater material prosperity, or more actual freedom? (Yes, there are no governments on Mars, but remember you'll be relying on supply ships from Earth, and if they don't like what you're doing up there, you can easily be cut off.)

    This absurd proposal has more in common with Jonestown than with Jamestown.

      The nearest analog of such a mission is to the kind of terrestrial expeditions that early Antarctic explorers made. Pain, suffering and unpleasantness were multiple and continuous, many horrors were faced and not a few forgotten, and the only thing that kept the survivors going was sheer stubbornness and obsession.

      And it still doesn't hold a candle to what we will face when we try to colonize the Solar System.

    Even if you breathe out as much as you can, there is still a lot of oxygen in the residual volume of your lungs. Your ability to hold your breath, I am told, is not limited by oxygen but by your ability to toleerate buildup of CO2, which triggers certain reflexes.

    Exposed to vacuum, I would think that even your residual lung volume gets vented. A similar thing occurs with asphyxiation with inert gas, say the pure nitrogen atmosphere in the X-15 cockpit outside the pilot's pressure suit. Milton Thompson wrote about how guys would lift their faceplate to scratch their nose, but they held their breath -- breathe in an you are dead. This inert gas asphyxiation danger has taken lives of farmers entering silos, where fermentation displaces the oxygen.

    That is also why they train pilots in altitude chambers to give them some measure of the symptoms of oxygen starvation and how to react. Exposure to low pressure is not like retaining your residual lung volume, although the first instinct would be to think otherwise.

    I am also told that Project Mercury had a fatal accident in a ground test of a pure nitrogen atmosphere, hence the switch to pure oxygen in the cabin, which in turn created the risk for the Apollo fire.

    Here's the problem. The so-called plan these people have is so utterly, completely, and totally ludicrously unrealistic it is not even funny.

    They're planning to spend $6 billion to design something like 10 different spacecraft, which will perform entirely novel missions in a largely unknown hostile environment. Their budget alone is easily 1 and maybe 2 orders of magnitude short of what is required. Their timeline is so utterly naive as to be simply some sort of fantasy.

    Yes, I know all about "oh, those government dinosaurs can't do squat blah blah blah..." but the truth is that the public space agencies, when they're given a specific goal that doesn't change constantly and is realistic, work pretty well. It cost well over $100 billion to put a man on the Moon in today's dollars. It cost an equal amount to figure out how to get the ISS up there and run it. Now, albeit you can CERTAINLY do those things more cheaply now, the things that are going to be done in this proposed mission to Mars are vastly different. To just pass off life support on the Martian surface as "Oh, its just like the ISS but easier" for instance is UTTERLY LAUGHABLE!

    Just a small few things that instantly spring to mind as likely mission busting issues:

    1) How do you land a large payload on Mars? This sounds like a stupid question but actually Mars is VERY HARD TO LAND ON. The reason is you're coming in from a fairly high velocity transfer orbit into a VERY thin atmosphere. This is NOT like landing on the Moon at all where you approach from a rather slow orbital velocity in a low gravity and just touch down with thrusters. Look at the MSL, which in order to get to the surface with a fairly small rover has to resort to a hypersonic parachute followed by a sky crane, a totally untested system that IMHO has maybe a 25% chance of working. How many billions will it cost just to get one of these landers (that are cavalierly passed off as "oh just a minor variant of the Dragon Capsule, ROFLMAO!") onto the surface. You can't do it with just rockets, takes too much fuel on Mars. Can't do it with a parachute, payload is WAY too heavy, etc. There have been MANY engineering studies done on this and it is NOT a solved problem. Just this ALONE could (and probably would) eat up the whole time frame and a large chunk of the proposed $6 billion budget...

    2) Someone has actually sailed through interplanetary space? Yeah, probes have gone this way and that, but I'm sorry, nobody has sent a large manned spacecraft 100's of millions of miles through the void to another planet. Just living in orbit for 6 months is a pretty good feat which few people have accomplished, and only at huge cost. Nobody has ever done it without resupply and it is at best a very dicey proposition to operate such a craft autonomously for 7 months. Nor are we really certain what the effects of such a journey would be on the crew. While one could say that "no new technology is required" there is a lot of very serious engineering that IS required, billions of $ worth of it.

    3) God only knows what happens to you when you land on Mars. The Moon is one thing, but Mars is far harsher than the Moon. It is covered in caustic and probably toxic dust. The air may be thin, but it is still thick enough to blow dust into every crack and crevice. It will be tracked into your habitat, etc. And what about this water? It is going to be magically just nice and drinkable? Really? We know that? There are 1000's of easy ways to die, and Mars almost certainly holds quite a few secrets in that department.

    4) Lets just estimate the chances of success based on how many missions need to be successful for the whole thing to work. LESS THAN HALF of all the spacecraft ever sent to Mars have arrived there intact and functioned AT ALL. Here we're talking about A DOZEN different landers. What's the actual probability that you get enough of them onto the ground intact in the right place? Surely they'll be more reliable than past missions, but there are also surely going to be quite a
