NASA Can't Ethically Send Astronauts On One-Way Missions To Deep Space 402

Daniel_Stuckey (2647775) writes "If NASA is serious about deep space missions, it's going to have to change its safety guidelines, because there's no conceivable way that, within the next few years, our engineering capabilities or understanding of things like radiation exposure in space are going to advance far enough for a mission to Mars to be acceptably "safe" for NASA. So, instead, the agency commissioned the National Academies Institute of Medicine to take a look at how it can ethically go about changing those standards. The answer? It likely can't.

In a report released today, the National Academies said that there are essentially three ways NASA can go about doing this, besides completely abandoning deep space forever: It can completely liberalize its health standards, it can establish more permissive "long duration and exploration health standards," or it can create a process by which certain missions are exempt from its safety standards. The team, led by Johns Hopkins University professor Jeffrey Kahn, concluded that only the third option is remotely acceptable."

        Can the astronaut accomplish the mission all by him or herself? Or does he/she need a ground crew and a team of engineers to design and build the rocket? If so, then they would all be participants in the astronaut's death. If I decide I want to die and I hand you a gun and ask you to shoot me, is it ethical for you to do so?

        But therein lies the problem. There are other people involved.

            And that is where the analogy falls apart. The launch button requires elaborate set-up, and the rest of the mission requires a large number of people working over many years. Even if you could get legal indemnity I think most people would feel some moral connection.

            So I wouldn't do it if it left my family destitute, but otherwise, what's the problem with this choice?

              Well here's the big problem: it's not worth it. Sending someone to Mars on a suicide mission wouldn't be a national accomplishment, it would be a national disgrace. We wouldn't learn anything new about Mars that we couldn't learn for fewer $ by sending many, many robotic missions. If the justification is "Gee whiz! I'm on Mars", then explain to me why it would have been worth it for the US to "win" the space race if it meant sending a capsule into space before working out the re-entry technology, so that the first man in space would have been incinerated while everyone in the US listened on radio.

              Minor problems:

              1. It would pretty much guarantee defunding of NASA. If not, then:

              2. Lawsuits filed by your daughter against any contractor that participated in the mission and probably the US govt. as well.

                By your standard, the Plymouth and Jamestown colonies were "suicide missions"; the people who boarded the Mayflower never expected to come back. The first colonists to Mars will never return, and probably wouldn't want to.

                But the difference will be, the Martians can phone home pretty easily - where a letter back to England was a rare event in the 1630's.

                  Flip side, those colonies were a helluva lot more habitable than Mars. People already lived there well before the colonists arrived, but I don't see too many indigenous species when CO2 freezes on the surface of the planet. The people you send there are basically stranded in the middle of the ocean, not sent to a lush and fertile continent.

                  This isn't to say the conditions weren't hard back then, but there's a wide gap between the two.

                  You're seriously comparing the Eastern seaboard of North America with Mars? Lets see:
                  1. People new a lot about the location before colonising (like we do now about Mars), so we're off to a good start
                  2. They knew the Americas had a breathable atmosphere (Mars doesn't - .145% O2), a minor setback
                  3. They knew the Americas had a habitable climate (Mars doesn't - average -55 celsius), not looking too good for Mars
                  4. They knew the Americas had native edible flora and fauna (Mars doesn't - we're still trying to find bacteria), survivability on Mars is decreasing
                  5. They knew the Americas had an ample water supply (Mars does - it'll have to be dug up and melted), well at least they can have a drink as they freeze death

                  Not detracting from what the colonists did, but they knew that they only needed to pack enough food and water for the voyage and the settlement time, plus the knowledge they could breath was an additional bonus.

          If I decide I want to die and I hand you a gun and ask you to shoot me, is it ethical for you to do so?

          Yes. Of course. Wouldn't it be ethical for me to inject your life-ending serum were you in terrible pain and wanted to die? OK, what if the pain is mental? What if there is no pain and you're sacrificing yourself for science? Look, just because some folks have a problem with killing people that want to die doesn't mean it's unethical to end people's lives when they really do want to die. That's their life, it's their choice.

          You had better wise up quick. Our technological progress may eventually render us immortal. We already have stem-cell brain injections and neuroplasticity drugs to help repair and improve brain function. We'll probably have lab grown 3D printed replacement organs in a decade or so (12 years was the time-line I last saw). Our machine complexity is increasing at an exponential rate. Machines have gained capabilities in a few short decades that took us organic lifeforms billions of years to achieve. So, what happen when you're an immortal? Everyone lives forever whether they want to or not? Fuck. That. Hard.

          I've got a game plot I'm working on where we deal with some of these ethical issues. Perhaps in a post-death world old timers will be the ones doing the really risky jobs that machines still can't do because they've been everywhere, done everything, and they aren't all geniuses constantly contributing to science. The ones who want to benefit their society best may decide to do so by taking really dangerous jobs or even suicide missions, boldly going where no man has gone before instead of just wasting resources thinking the same old thoughts and seeing the same old things. Whereas others explore the limits of understanding, they may choose to become daredevils exploring the limits of reality and life itself. In death they can become heroes and die knowing they have sacrificed themselves for the greater good of all.

          We don't have to wait for immortality to realize these are noble causes. It's not like we have a shortage of humans that it would cripple us if a few decided to give their lives in the name of science.

          If you don't have the freedom to peacefully sacrifice yourself for your species, planet, country, family, etc... then you don't have free will. No one is obliged to help you off yourself, but if they do it's not unethical. Are you even aware of the history of space exploration, or exploration in general? You sound like one of those brain-washed fools who advocate against free will of the terminally ill just to make the medical establishment a huge fortune, profiting via human suffering; Meanwhile staving kids fight wars over diamonds, electronics scraps, or food, with AK47s in Africa and you're not lobbying congress to do jack shit about it. I sure hope I'm wrong about you. Someday you might be one who's begging for death. If you keep that bullshit opinion of yours now, I hope that happens and your kids say, "Sorry gramps, looks like another 8-10 years of excruciating pain. You're not in control of your own life anymore because Pfizer has to make a buck somehow!"

I won't comment on how often that justification was valid (cause it would get depressing) but in this case we don't even have that justification/rationalization. The only reason is the chance of a "Hey look! I'm on Mars!" tweet/selfie, and the research that could have been done cheaper by robots.

    There's no conceivable way that, within the next few years, our engineering capabilities or understanding of things will be able to do a manned deep space mission to Mars, safe or not. We could try to just put a bunch of guys in a box and send it that way. I doubt we could design, build, orbit, and then get the box on it's way in the "next few years". Let's be serious. Nobody with space capability is looking at a Mars mission any time soon (next few decades*). The level of complexity needed will take time, research, and money. We didn't go to the moon till Apollo 11. Once you start seeing your Mars missions planned, let alone counting up, then we can start being serious about going to Mars. Seriously, we need to test deep space habitats. Long term independent space habitats. Long range movement of large structural objects in space. I bet we will have a deep space station and have sent something similar in a long trip around the moon long before we attempt Mars.

They knew the failure modes, the risks, the potential ways they might get splattered across our planet in fiery ashes. And they still wanted to go!

        Note that all three of the above represent "easy" scenarios, where help and/or an emergency return to Earth is always minutes, hours, or days away. On Mars (or en route to Mars), help from or escape to Earth would not be a likely option.

    • Stick to robotic missions, which are better value for money anyway.

      I know that's the common belief, but is it true?

      Robotic missions are cheaper. But robotic missions seem to beget more robotic missions to answer questions that the first robotic missions weren't able to answer. And so on and so on and so on.

      Did we learn more about the Moon from the 6 Apollo missions that landed than we did from the 18 or so successful Soviet Lunar probes?

      • The robot missions are limited to using the equipment that they've taken with them. Woudn't a human mission have exactly the same limitation? There's a limit to what you can achieve with a pickaxe and a screwdriver. Anyway, I expect that a human mission would be so tied up in just keeping the humans alive, that they'd have little time or resources for any actual research.

      There was a time when attempting to cross an ocean was suicide, but the technology get better. Well, the financial rewards got better and technology caught up.

      In any case, the analogous space travel technology is not there yet.

      • It's not so much the space travel technology, but the technology that would allow a truely sustainable human colony in a hostile environment. Show me that it's even possible to build a sustainable human colony in a domed city somewhere on Earth (without importing food, water, computers etc.,) and then perhaps it will be time to start thinking about living on Mars. Then you can start worrying about all the true space problems, such as shortage of water, excessive radiation, and wrong gravity and temperatures

    Magellan didn't survive Magellan's expedition. Scott died trying to get to the South Pole. Mallory died climbing Mt Everest.

    How many still die climbing everest even though its been climbed thousands of times? How many people die in bat-suits?

    We are not talking about forcing people to take risks, but rather of looking for people who are willing to risk death to become immortalized in history. Have we become such collective cowards that we will not accept risks that daredevils accept daily for fun?

    Take volunteers. Make sure that they understand the risk and are not in any way coerced. Send them out. If they die, build a grand monument to their heroism, and look for more volunteers. If they succeed build grand monuments, and bury them there when they die later - as they inevitably will.

    In a hundred years everyone reading this will be dead. Give a few of them a chance to do die doing something magnificent.

    • Problem here is that you cannot ethically send anybody to certain death just to go explore Mars first hand.

      The radiation exposure required for a trip to Mars is significant. The total expected dose is high enough to warrant asking ethical questions about what risks we are asking people to take to make the trip.

      • Problem here is that you cannot ethically send anybody to certain death just to go explore Mars first hand.

        Of course you can. This whole argument is ridiculous. YOUR ethical system may not allow YOU to voluntarily go to your death that way, or YOUR ethical system may not allow people to be forced to go, but MY ethical system says if they CHOOSE to go KNOWING the danger then let them. Why should you make that choice for them?

          If we don't have boundaries and stick by them, things like Challenger or Apollo 1 will happen and we will have needless loss of life because we didn't asses risks properly or take them seriously enough.

          There's a big difference between "taking a calculated risk", or even "choosing to commit to a one-way trip", and "not taking the risk seriously". Challenger was a horror not just because people died, but because it was ALREADY KNOWN that the O-rings and joints were a weak spot in the design and were particularly affected by the cold conditions. The astronauts CHOSE to sign on with the implicit understanding that everyone behind them was doing their absolute best, and in this case institutional inertia hel

        Of course you can send someone to certain death. The problem is peoples ethical radars are so fucked up today that they don't believe in peoples right to make such a decision for themselves. Personally I find it far more ethically questionable that you believe people don't have a right to make this decision for themselves.

      • I am content for there to me more Challengers and Apollo 1's. We honor brave people because they take risks. I believe it is wonderful and noble that people are willing to die to expand mankind's reach. This loss of life is not needless, it is the natural result of pushing the limits.

    • The interesting question is did they need to be sent?

      To me, exploration is about seeing what has never been seen. That can easily be done with robotic probes that have cameras and we would see what has never been seen on our screens at home. I've enjoyed the various views of Mars, Venus, Titan, and the Moon. There's not a great reason to send people out there to explore the Solar System.

      However, if we want to learn about what we're seeing, I think people are a better choice than probes.

      • It depends on the long term goal. Personally I have a long term goal of human expansion into the universe, and I believe that to further that goal we need to try - accepting that many of the explorers will die. If the goal is pure planetary science, then it may well be possible to do it with robots.

    • Magellan didn't survive Magellan's expedition. Scott died trying to get to the South Pole.

      No, Scott died trying to get *back*. On the other hand, the ancestors of the various Pacific Island peoples managed to find their ways to little dots of rock in the middle of a really big ocean, and managed to survive and succeed and have descendents to be ancestors of. There must be a few remnants of that DNA left in some humans, somewhere.

  • NASA can do alot of things but they suffer from "paralysis by analysis"

    It comes from the assumption that "safety" as a concept can be quantified. And that's just the beginning...sure we can use data to examine possible avenues of mission failure but we put too much of our decision making process into raw numbers.

    "risk assessment" as applied by NASA is a reductive concept.

    • Success or failure of a mission is a question of identifying & mitigating all the factors that may cause the conditions we define as "failure"

      That is what Operational Risk Management is all about.

      When "success" includes "the participants don't come back" as part of the mission, then it isn't a risk management decision anymore. Saying "it's too risky" because "they won't come back" is meaningless.

      It's fatalism at its worst. Nobody will come back from any of the first 100 manned missions to other star systems. We better not do them, it's "too risky" and we might "fail" because people will "die" doing this. Let's just sit back and relax and have

    No, it is not that you can't ever send a person on a mission with a high risk of premature death - it is that you need a compelling reason to do so.

    What is the compelling reason here? Is the compelling reason that the astronaut can collect scientific data that a robot cannot? This is a ridiculous proposition, if you give it any serious thought at all. Any instrument the astronaut can operate, a robot can operate with remote human guidance. Cameras can see anything the astronaut can see through his helmet or window, and much, much better too. Mechanical tactile sensors can be vastly more sensitive than hands reaching through thick pressurized gloves.

    Or do you imagine that this lone astronaut will perform science that cannot be matched by, oh, 100,000 scientists back on Earth not tasked with life-and-death survival problems every second of every day?

    And sample return missions are far more productive when you don't need to return a scientist and all of his/her life support equipment, before you get your first gram of actual sample.

    Bottom line - sending a person to Mars has vastly less scientific value than spending the same amount on robotic missions, collecting data for the world's scientists.
