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

The only danger is if they send [them] to that terrible Planet of the Apes.
Wait a minute....
THL phish sticks
If they can't send them ethically, then send them unethically. Doesn't take a rocket scientist to figure THAT out.
rewriting history since 2109
Let China go first.
We've lost all tolerance for risk or voluntary harm in the pursuit of a larger objective.
But no worries. China is picking up where the USA left off on a lot of fronts.
Ask North Korea for volunteers. I bet they'd gladly go just for the food alone.
Whether sending a willing astronaut, who understands and chose to do this of his own free will, on a dangerous or even one-way mission is ethical is not a question for anyone except the astronaut. It's like trying to decide if gay marriage is "ethical". Unless you're one of the ones involved, nonya business trying to define ethics.
Real programmers use "copy con program.exe"
If we start sending legal adults who can make their own decisions in to deep space, it is a slippery slope that leads to sending children and people married to hamsters too!
3D printing and computers got better? Surely every other technology got better too? We must get the species off this rock! Because those other rocks is where it's at!
off topic... I know... but I just got redirected to beta again... Wtf? I thought we were finished with this shit? It doesn't even look like they have bothered to make any of the changes everyone has been recommending...
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.
*Elon Musk said it's possible in the next 10-12 years. I think he is just being overly optimistic, and that is overly optimistic, to get in the papers.
"I understand and agree that taking part in this mission will result my death"
Surely, given the activity level of many seniors, they could take on the really dangerous missions. Same goes for terminally ill people. If they're more concerned with science and discovery than with coming home, we'd all be better off. I'd guess that there are many seniors/terminally ill folks who be willing to take on a dangerous mission with little or no chance of returning. I'm not either of those and I would jump at such a chance. Why should we waste all that human potential?
Just sayin'.
No, no, you're not thinking; you're just being logical. --Niels Bohr
The hell you can't. What that's saying is "we refuse to honor the wishes of educated, rational adults to make decisions we wouldn't". I guarantee that all of the Mercury astronauts knew there was a good chance they were going to die during each mission. 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! I cannot understand how it could possibly be unethical to explain the dangers and still give candidates the right to say, "yeah, I know I'm not coming back. For personal pride, for adventure, for my country, and for humanity I choose to go anyway. Now step aside and light this candle."
Dewey, what part of this looks like authorities should be involved?
...otherwise it is guaranteed that thousands will die. I like this line of reasoning.
Stick to robotic missions, which are better value for money anyway. Humans are tied to Earth more strongly than science fiction would have you believe.
Only money is important. Tax money cannot be extracted from people who leave the Earth on on-way missions. Tax money cannot be extracted from deceased people who are not alive to pay taxes. Government authority has a directly selfish financial motivation to keep people Earthbound and alive. Ethics is a fabricated fiction of government greed.
In this case, microwaved spam.
I am very small, utmostly microscopic.
They can be the first settlers on Mars. Did most early voyagers to the New World worry about how they'll get back? They were going to live there. We can do the same for Mars.

You send astronaughts who are diagnosed with terminal illnesses. Particularly, those with a number of years left of health, but for which eventually, will die anyways.
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.
I have a chronic disease that can be controlled through medication that already limits my lifespan.
Because of this I deliberately have no children or spouse and I avoid developing long term relationships.
My Parents are old and are unlikely to outlive me anyway.
I am aware of the implications of a one way trip to Mars and realise I wont be coming back and wont have any new companions for at least 10 years... if ever.
Send me.
Accidentally dump 90% of the fuel so they can't return, leave enough for maneuvering/corrections, blame the cheap valves or dried orings, win-win.
Congress is not mentioned above, in the summary, or in TFA. I suggest this is because we are officially a nation of men, not a nation of laws.
Though you might smirk at the suggestion. This is a non-military (non-commander-in-chief) decision. I don't think it falls to SCOTUS here nor NASA administrators themselves. Ask Congress, live (or die) with the answer.
Fusion Rocket Could Take Us To Mars
NASA-backed fusion engine could cut Mars trip down to 30-90 days
Get this working and the proposition isn't so bad anymore.
Oliver's law of assumed responsibility: If you're seen fixing it, you will be blamed for breaking it.
If we had done anything ethically on this planet we wouldn't have to be looking for a new one to move to in the first place...
As living in Detroit? Or New York City? or has everyone just been given the life extension pill, so you can live forever?
Does NASA have employee health care, or are they exempt because the Dr's may kill the patient accidentally?
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!"
Seriously. How the fuck did this moron get rated so highly is beyond me. Dying for piddling oil wars is somehow acceptable, but to advance the human space frontier is questionably not ethical?! Fuck all those mods, apparently you're not the same species as me after all.
I think we should start with establishing a self-sustaining base on the moon before we even start talking about trying to colonize mars. That way when things inevitably go wrong, we can just send the astronauts back to Earth instead of having them die. This will allow us to solve all of the problems with living for extended periods of time in space without the dangers of going all the way to mars.
Gay people have at least a few other people involved in getting married too ( minister/justice of the peace/whatever to perform the ceremony, two other people to witness it ). That doesn't change anything. People also like to do dangerous things like jumping out of perfectly good airplanes. It is not immoral for the parachute manufacturer to sell them a parachute, nor for the pilot of the plane to fly them up. It is their choice. Your analogy about asking someone to shoot you isn't applicable here since they are doing their best to make sure they survive, even thuogh they have no chance of coming home. In the end, the risks are probably a lot less than those faced by early settlers of the new world.
It wouldn't be the first time the government sends voluntary men and women into harm's way.
The only difference is that no one else gets killed in the process and humankind benefits from it.
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"
Identify & mitigate...that's all we ever do with "risk"...NASA is playing a shell game here
Thank you Dave Raggett
Someone said the following in regards to any "forget the USA, China's all over X b/c the USA has Y failing"

Seriously. How the fuck did this moron get rated so highly is beyond me.
Perhaps because instead of being a self righteous prick he expressed a valid point very clearly and simply. You on the other hand....
We sent people up into space when we thought there was a 50/50 chance they'd die in the process.
It's called "being an astronaut".
Don't like, don't sign up.

-- Tigger warning: This post may contain tiggers! --
WAT? Somehow you managed to turn a rational discussion about the ethics of space travel into a strawman argument about euthanasia. There are plenty of ways to make a name for yourself and go out with a bang here on Earth. We don't need (or want) astronauts that just want to be the first ones to die outside the solar system.
Humans will travel into deep space when it's "safe". By safe we don't mean "0% chance the trip will end in a fireball," and not even "not a one way trip / eventual lonely death in cold space mission." By safe, we mean that the crew will have the ability to sustain themselves for the remainder of a "natural" life expectancy. In order for that to happen, it means we'll hvae to send them packing with enough enough oxygen, food and water + recycling of all waste products, decades worth of various types of medication, radiation and particle shielding, and a reactor powerful enough to sustain "comforable" living conditions for decades.
Or, we could come back to our senses and do basic animal tests for long term deep space exposure. Like, start from a small rotating artificial gravity satellite with lab rats, and if you really have balls, send a couple of chimps to loop around the mars and come back.
We did that in early days no problem, and it retired a lot of early risks for humans.
Hey, we even had a grassroots program : http://en.wikipedia.org/wiki/M... - got no real support or funding by NASA.
In fact its super lame that we only have data points for humans spending time in microgravity and 1g, but nothing in between. So we have no curve to fit to partial or reduced gravity effects on health. After decades of multibillion dollar manned spaceflight investments, thats pathetic. The fact that we dont have a biological lab sitting outside of van Allen belts right now testing different radiation shielding approaches on rats is also pathetic.

There is a difference between a risky endeavour and certain death.
Instinctively, we accept risk of death when the reward justifies it. Being a successful astronaut is rewarding - in terms of prestige if nothing else.
A compelling scientific mission that will add to human knowledge is arguably more rewarding for civilization, but not for the individual who dies, and the reward is too abstract for our instinctive response.
Plus it's not obvious that there is a lot that live astronauts can do that do that robots can't. Simply 'being first' will not be a compelling reason for others to enable suicide, or be left to watch it helplessly from a distance.
Does it really take some 80 pages to say "informed consent".
As long as non-fiction analogues of "deflector shields" and "artificial gravity" continue to cost too much to drag out of earths gravity well people will continue to not deserve to go to mars.
But two of them signed up to apply for that one way trip to Mars. Something about the fame or the experience. I would do it if I had a terminal disease.
Hell yeah. It's OK to send 18 year old barely-not-children-anymore to the hell hole Middle East with a pretty decent chance of dying - and usually for something shitty like a roadside bomb on top of it - not even in direct combat defending something - just in hopes that if they survive their education will be paid for - yet it's not ethical for someone to go to freaking Mars voluntarily if they want?
To quote you - Fuck. That. Hard.
Our priorities here are beyond fucked - but you only have to look at the war budget vs the NASA budget to know that. I'm sure someone has the statistics, but I'm pretty sure that what we spend on NASA in a year is equivalent to what - hours, days in war funding for the Middle East?
Have you missed the project where an independent entity is doing just that? They were taking applications last year. www.mars-one.com
Put a death row inmate on it.
NASA is already showing its wood for Political Shenanigans visa vie Russia and Dictations from El Presidente Obozo (formerly known as the half bread boy Barry later to adopt his Fathers Name Obama to become Barak Hussein Obama) to Herr General Excellency Herr Majesties Fleet Capitol Ship Mr Bolden his most post humas.
Bad NASA. Bad NASA.
SINK THE BISMARCK !
These committees are always chock full of doctors and policy wonks, and hardly a philosopher to be seen. I dare NASA to ask 10 of the world's leading philosophers for input (you won't get them on a committee, so don't try - they'll each send you their own answer, thankyouverymuch). Half of them wouldn't even think it was a good question; the answer being, "Duh, of course informed adults can accept death in pursuit of their goals. Why would you even ask such a question?" Most of the rest would say "Go for it man. You should be very careful, and understand that you'll feel bad in the end no matter what, but there's no show-stopping moral issue here."
Doctors and governments are so "ethical" that they'll withhold potentially lifesaving medicines from dying humans, because they haven't been tested on perfectly healthy rats yet. When it comes to medical ethics, run, don't walk.
The justification for sending 18 year olds to hell holes has always been that the consequences of not doing so would be much much worse. 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.
Thnx for the comment...I think we're likeminded on this topic
So here's where TFA makes the error:
then this **isn't** a question of "risk" at all...it's about limitations of engineering and materials science
the assumption/error is when TFA says "there's no conceivable way"...that's B.S.
hundreds...***hundreds*** of studies have been done on radiation exposure and shielding by NASA, JAXA, ESA, Soviets/Russians
there is certainlya conceivable way we could engineer proper radiation shielding
Thank you Dave Raggett
I agree with you, in part. I disagree also, in part.
While I think it's actually noble of people to sacrifice themselves for the greater good, I think his argument comparing it to him asking to be killed is not the same thing. One has potential large tangible benefits for humanity (pushing science's boundaries), the other doesn't (he dies, doesn't use the resources he would have, and that's it).
The thing is, is that a large portion of the time, a person committing suicide is usually caused by temporary circumstance. Don't get me wrong. Depression sucks, but more often than not, it's temporary. I'll just use the old adage "a permanent solution to a temporary problem". There are obviously exceptions, such as terminal illness, chronic depression, and other things that we can't really fix (though medication can sometimes help), but since that isn't always how it is, I think you can't just go "It's their life." and pull the trigger without considering these things to define if it's ethical for you. It should be a last choice, because there is no going back (yet).
There is absolutely no comparison.
First, all major cities in human history have had homeless people living in them...this isn't about that at all
***population density*** in Detroit/Chicago is much less by several orders of magnitude.
America doesn't have slums like this: http://image.architonic.com/im...
China has **slum cities** with no city sewage services...with >10,000 people living in it
**that** is shitting in the streets
Thank you Dave Raggett
Manned space programs are significantly more expensive and the benefits are dubious.
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.
Starships were meant to fly, Hands up and touch the sky - Nicky Minaj
Why send astronauts when you can send "volunteers"... lol
worker health issues need not be a priority over profits.
Nobody ever discovered new lands by sitting at home and playing it safe. Every time a boat went out to sea in the Ancient world, there was a risk of death from numerous sources but that didn't stop them. The shipped out as fast boats were built.
NASA: grow some balls, you gutless bastards. People are going to die in space. Its going to happen and there is no way around that. Now get off you asses and put some people on Mars. Every person who goes on that trip knows that it is going to be a one way journey and the only person fretting over it is you.
HA! I just wasted some of your bandwidth with a frivolous sig!
They'll be doing better than on the Niña, the Pinta and the Santa Maria.
The difference is that Kennedy made a commitment to get there and back. Once that was done, the technology was developed.
I'm confident we have the technical ability to at least get a man to mars safely, and if not, we have the technical ability to develop it in a relatively short period of time. We simply do not have the drive to do so.
Until someone makes a commitment, with a time-frame to get shit done, it won't get done. Part of the lack of commitment is adversity to risk, and politics.
As per other posters, we send kids off to war with a possibility of dying, and the explorers of old set out not necessarily knowing whether or not they would make it. WITHOUT any longe range communications or possibility of re-supply, no less.
Mars One is planning a colony drop, not a suicide mission. Colonies have a history of failing, but they also have a history of succeeding.
If we're talking about a mission with no hope of surviving to go on speaking tours, or build the foundation for a society elsewhere, I can't really see any good reason for it.
On the other hand, throw a NERVA, Orion, or a (FSM help you!) NSWR at the problem, and suddenly it's a shorter trip than most jaunts to the space station. If Bussard was 1/10th right, deep space missions won't be suicide missions.
... as a motorcyclist, i am statistically 29x more likely to die on the roads than a car driver. I still ride, every day.
Minor point... NASA cant actually send anyone anywhere today....isnt the whole discussion and research a moot point... any US space travel will be soon private and they can do whatever they want, including using the policy paper to save forests in washrooms
Danger implies risk. Risk implies different possible outcomes.
If we send a meatbag to mars, they're not coming back before they spoil. There's only one possible outcome. It's not risky OR dangerous. It's guaranteed lethal. So now that we've gotten that out of the way, lets continue with the booking please? (and I wouldn't mind signing up myself, but I rather doubt they'd take me)
I work for the Department of Redundancy Department.
I wonder what are the health standards and ethics applied by the US military? Do their health standards allow sending someone on a one way mission? Or on a mission with a serious health risk? Maybe NASA could borrow the books from the Marine, or just pass the mission to them.
Vajk
in other words....the usa can't find a way aorund the tech requirement to safeguard vs radiation. ALSO corporate power is such that it will not allow NON PROFIT space travel.
That's why we already have thousands of people just raring to go. It's not about ethics, it's about exploration and knowledge for mankind. When we were still exploring regions of this planet, people weren't asking if it was "ethical" to get on a boat and go as far as they could even if it meant they fell off the edge of the Earth or got pwnd by Poseidon :P They wanted to go just to find out what was there. No one is forcing anyone to go on these exploration missions, therefore "ethics" simply don't apply. Come on NASA, you should know this.
Why not just call it a 5-year mission and cancel it after the third season?
why the hell not let them die for a good cause that benefits all mankind?
Our planet is in serious danger. We didn't know this in the 60's. Now we do.
We need our planet, our nature to survive. Not the space. Please turn the space agency into a earth agency. There are too many good engineers there.
Our children will be thankful.
Robots are slow. They can't dig. They can't carry out the most sophisticated tests. All they can do is take pictures and run basic chemical analysis. A small crew on mars could accomplish so much more. They could run drills to see beneath the surface for a start - all robots can do is scrape a few centimeters down.
Worth reading: "The Metamorphosis of Prime Intellect" - http://localroger.com/prime-intellect/. There's also "Perfect Imperfection", but only in Polish, here's a good review: http://www.terminally-incoherent.com/blog/2011/07/08/perfect-imperfection-perfekcyjna-niedoskonalosc-by-jacek-dukaj/.
We need a long term plan. We missed an opportunity with the original space shuttle.
If the payload area was modular and left in orbit after each mission it could have been reused to create a next gen hybrid space station/habitat/vehicle. Just from the American missions we know about it could have resulted in a ring shaped station 2.5km in circumference.
This is the type of work we need to do, then move it under power to mars orbit to create a permanent station, from there we can start sending materials for other endeavors.
People can take their own life and throw it away. It's stupid but their own decision. However killing someone on demand is unethical. It's still murder. Many survivors of suicide attempts are grateful for being saved from their own stupidity. Now, sacrificing your own life for some greater good is even stupider. It's the ideology of jihad.
A robot that costs and has the mass budget of a human mission could easily do all those things and more. Current robotic missions have mass/energy budgets that are a small fraction of anything a manned mission could be.
If information wants to be free, why does my internet connection cost so much?
Dying for piddling oil wars is somehow acceptable, but to advance the human space frontier is questionably not ethical?!
A one way mission to mars with not advance the human space frontier one iota. It will however cost a lot and have good odds to fail to even get them to mars.
If information wants to be free, why does my internet connection cost so much?
China wins round two of the space race.
What a shame... we didnt even try this time.
Maybe we can get our act together again for round three.
Suicide missions are acceptable ONLY if volunteers are to save lives - for example, a operative who gives her life to stop a act of nuclear terrorism. The solar system has been around 4 or 5 billion years and it can wait for us until we can explore it safety and return. Certainly not with MY taxes!!!
Instead of sending death row inmates to execution why not send them to deep space and collect data?
Heck, if they make it back alive give them their freedom.
Have a squat over at the hobo house.
And whenever you dig up something that requires a more sophisticated test than you've thought about beforehand, you need to build a new robot.
Yes, in the long run we will all have to commit suicide. When technology makes our bodies eternal the only think left is to see how long the "software" can survive. If you live for say 5000 years, would you remember anything from, say, the first 1000? And if not then you are by all means another person. Then it is not "you" that survives for 5000 years. Or maybe we will never loose sense of who we are and it will be still "you".
One way or another it will become boring to be immortal. IMHO, immortality that cannot be ended is a severe punishment, not a blessing. In that respect I find it a bit hilarious that the believers have sentenced their gods to worst possible existence - immortal and all-knowing. What a drag....
Robots are slow. They can't dig. All robots can do is scrape a few centimeters down.
Just put an Arduino in an excavator. Job done.
Oh, the real problem with sending earth-moving machinery to Mars is the weight.
Humans would add waaaaay more weight to a mars mission than a bigger spade on a Mars rover ever would.
No sig today...
Isn't a one way trip just something you don't plan to come back from? Is it unethical to build planes that help people take a one way trip to France? Kidding aside, what's the difference when letting a grown adult decide where to spend the next decade of their life? We all die some day, and if the technology is there to support you, who cares where you want to do it?
I'd bet on a human with smelting equipment and a 3D printer over any robot made to date.
The premise that we can't make space travel safe is simply unacceptable. It is just another stupid exercise in ethics puzzles. We shouldn't even consider sending humans on certainly lethal missions in space. Even if we are sending only volunteers, we accomplish nothing of worth for humanity, we prove nothing, and at the same time, we lose huge amount of money on it. If we are ever going to send humans into deep space, we must solve the accompanying problems first:
1. problem of safe travel: high energy particles shielding, artificial gravity,
2. problem of safe lodging on other celestial bodies: mostly the same, plus mitigating specific environmental risks, such as mechanical and chemical (in)compatibility of regolith with human biology,
3. problem of sustained life support: recycling the metabolites into breathable air, drinkable water and food.
4. problem of medical care, and eventually, of handling dead bodies (recycle, like with metabolites?)
5. problem of maintenance and repairs of other equipment during the course of voyage.
6. problem of compact and strong propulsion capable of shortening time spent traveling in hostile environment.
If we can thus extend survivability of our expedition, we may as well send them on one way trips and resupply them periodically. If they will live shorter then robots once they reach their destination, or if they are going to be badly incapacitated for exploration on arrival, then it is simply not worth it.
How can you have colonization if the colonists build a mostly self-sufficient village in a new location and then everyone returns "home" instead of making the new location their home? Therefore it is a logical conclusion that NASA is against colonization and therefore we will have to look at other entities to pursue interplanetary colonization.
The projected risk of astronaut survival might have been 50/50 at the initial assessment of the Mercury program but because NACA (later NASA) didn't have a crystal ball and could predict the engineering changes and a little luck that made Mercury program astronaut's survival rate 100%.
The justification for sending 18 year olds to hell holes has always been that the consequences of not doing so would be much much worse. 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.
So what you are saying is, as long as we have a good lie to deceive ourselves with, then A-OK!
Just do a reverse-Sunshine on it.
Put a huge mirror behind the ship made out of artificial diamonds. Since they have a high density, the chance of radiation leaking through that will be less.
Make it a couple inches thick, basically no chance.
Instantly you cut more than 90% of the radiation risk with only a tiny higher expense of weight. (which would also act as a solar sail to an extent)
Better yet, just make 50 solar sails behind it (not 50). That way it can be sucked back in when landing on Mars, and it is very cheap.
Or just suck it up and fill the entire ships outsides walls with water, no windows (who the hell will need side windows anyway?) and only cameras
Actually, backup window in case of emergency, but it is always down by default. Always gotta have a backup. I'm sure even some tanks had backup windows. (although these days it is usually a hardened scope I think if cameras somehow fail)
God, the day space mining happens, the better. Then we will truly be in the space age. We are still yawning on mummies boobs. My, what big boobs you have. I'm sure this ended badly for the baby. Something about wolves and a houses made by piggies or such.
Just don't tell the astronauts and build a super-computer to sort out the messy ethical questions.
We can't even get to the Moon anymore and we rely on Russia to get to the space station. NASA has become a joke.
Going to Mars to die advances nothing.

Very bad analogy since those colonies were clearly capable of sustaining life and people went nearly that far and back to catch cod every year back then. I think your "never expected to come back" may be correct in some cases but in general it is very unlikely.
Also this would be a suicide mission for reasons of the very harsh environment so that makes things very different.
Robots could do that was well. We just need to design them and send them.
When you are talking about comparing costs. Right now we send robots for dist cheapo. If we sent robots with the same budget we would need to send people, then drilling and digging can be done.
I wan't people to go to Mars. I think the is a lot of value there. I don't want them to go there knowing they will be dead in a month.
Send some support infrastructure, send some automated system get it set up, then send people.

"The dinosaurs became extinct because they didn't have a space program." -- Larry Niven
It is said of the space programs that science is what matters, but without astronauts to sell it, little science gets funded.
So, no astronauts means no space program.
And we all know how that turned out for the last apex predators of this world.
But it can UNethically send them.
Humans will travel into deep space when it's "safe".
So, in other words, never.

We can put combat troops in hostile areas with unloaded weapons, but can't send volunteers on exploration missions.
Does anyone else see the contradiction here?
people voluntarily go to the Antarctic to work, and the radiation levels there ar ehigher than "normal",
Airline pilots an dmilitary pilots are routinely exposed to "abnormal" radion levels while flying. short term not a big deal but over a career, results are unclear.
I think that what it comes down to is are we going to let "safely" determine our future? or are we going to take risks to advance our knowledge.
Just saying.....
Well it's a good thing that a space program doesn't require suicide missions. You can even have astronauts with no suicide missions! You just have to send them on non-suicide missions.
(Other threads have gone into the difference between a one-way mission and a suicide mission; I think a non-suicide one-way mission has way fewer detractors)
I don't actually believe that "no astronauts means no space program".
WhooOOOP! WhooOOOp! Loony alert, loony alert! All personnel prepare for loony situation!

Send a 3D printer and tell it to make a new robot. You just need to be sure it can access the intertotrrents to get the plans. Because ST:TNG and that.

I keep seeing people saying that it is cheaper and safer to send automated missions and that they can do everything a human can do and more in the way of research - that a human would add nothing to knowledge that can't be gathered by machine.
This isn't true. An automaton cannot tell us what it is like to be a human on Mars. Admittedly, some might find that insufficient - but I do not.
(Also, the science and technology we will develop HERE to make a human *able* to stand THERE and tell us that is nothing to sneeze at, either.)

If I was in NASA I'd say - correct me if I'm wrong, but you want us to spend a lot of money that we don't have on a mission that a lot of people would vehemently hate and our funding is at the whim of people in politics? Given THAT do you think we are even going to listen?
I hear that Iran is working on a space program. Maybe you should talk to them.
The test flights show your premise is utter bullshit. If they were willing to accept such losses there would have been no point doing the tests.
Who fed you this 50% line or did you just make it up?
Yep. And sending the first robot out, running into difficulties, sending out the improved robot, having it fail to deploy, sending out the replacement, realizing there are new problems you want to address, and sending out a new type of robot would still be faster than planning and sending a manned mission. It would also be cheaper, so you could send some robots to Europa and Enceladus too. Why wait til a ~2035 manned mission to learn stuff we could be learning about via robot this decade?
My thoughts are more along the lines of: selling a good lie doesn't make the goal worth the costs. I'd also say there's a big difference between high risk and planned death. A mission without plans for supplies continuing indefinitely or a way back is a suicide mission; a plan that exposes astronauts to a sievert of radiation and engineering mishaps is a high risk one. It's the difference between Kamikazes and the Doolittle (Tokyo bombing) raid.
