What Is an Astronaut's Life Worth?
An anonymous reader writes "Dr. Robert Zubrin has some interesting ideas about what it costs to have an astronaut on the payroll. He says if you’re going to 'give up four billion dollars to avoid a one in seven chance of killing an astronaut, you’re basically saying an astronaut’s life is worth twenty-eight billion dollars.' He wrote about the same subject earlier this year for Reason magazine, saying, 'Keeping astronauts safe merits significant expenditure. But how much? There is a potentially unlimited set of testing procedures, precursor missions, technological improvements, and other protective measures that could be implemented before allowing human beings to once again try flying to other worlds. Were we to adopt all of them, we would wind up with a human spaceflight program of infinite cost and zero accomplishment. In recent years, the trend has moved in precisely that direction, with NASA’s manned spaceflight effort spending more and more to accomplish less and less. If we are to achieve anything going forward, we have to find some way to strike a balance between human life and mission accomplishment.'"
This assumes NASA's #1 priority is manned spaceflight - a premise I do not accept.
From New Horizons to Cassini and Messenger, the amount of non-manned spacecraft visiting Mercury, Saturn, and Pluto to expand our knowledge of the solar system in just this decade has been extensive. (Oh yeah, and the Mars rovers - the asteroid mission, etc. etc.)
He is being a bit of a blowhard to say we've nothing to show for the money NASA has spent.

Dance like no ones looking and love like it's never going to hurt.
As a mindset, I'm tempted to disagree. It works when used as a goal, because for every fatal accident, you will have a lot of near-fatal-accidents. Often it is trivial mistakes, and by investigating the near-accidents to find the cause, you can mitigate the risks. The norwegian oil industry has been working towards zero accidents for years, and is way safer than Gulf of Mexico. In Norway, we investigate those near-accidents to find the cause, and implement precautions to avoid it to happen again - potentially with a much more lethal outcome. I am aware this is not the same as zero risk tolerance; we are tolerating the risk, but aiming to reduce it as much as possible through targeted work.

He says if you’re going to 'give up four billion dollars to avoid a one in seven chance of killing an astronaut, you’re basically saying an astronaut’s life is worth twenty-eight billion dollars.'
Only if you ignore the other costs a disaster entails, e.g. fewer candidate astronauts, less qualified candidates, a perception of the program as being a failure which could end up in reduced funding, etc.
If your astronauts bite the dust, so does your mission. If you start saving on safety measures and something goes wrong, it will probably mean that you will also lose the transport vehicle along with all the equipment that the astronauts were supposed to use/deploy on their mission. Killing the astronauts is merely a corollary, albeit a tragic one. If you rig everything up so that the mission can go on in case of e.g. just a life-support equipment malfunction, then you would surely be on the cheaper side if you sent an unmanned mission in the first place.
Besides, I can surely imagine that the life of an astronaut is worth a lot of money, even if we neglect the value of human life per se. The life of an astronaut on the ground is worth, I would say, as much as his education and training, which is probably the most expensive a human being can receive in our culture. The life of an astronaut in space is all that, plus every dollar spent to manufacture every bit of equipment that he/she is carrying with him/her, because if he/she dies during the mission all that will just be a pile of junk in space. To that you may also want to add the cost of the next mission that will be sent to do what the first one didn't manage. And if you are still so stubborn and choose the cheapo life-support system to save a few bucks (compared to the total cost), you will have to factor in the cost of the next mission, and the next, and the next... In the end all that matters is "we spent X billion $ to manage Y". The more missions you spend on trying, the higher X will be.
In another tone, I don't really understand why it "doesn't count" to send unmanned missions in our stead. To the people that say that "we haven't been on mars", I just reply, "I, for one, welcome our new robotic overlords".
Back in the 1980's, NASA announced that with the Space Shuttle space travel was now perfectly safe
Sorry but they shouldn't let dumbasses make public proclamations simply because they sound good. It leads to the kind of disappointment you mention. Look at the number of traffic injuries and fatalities. We can't even make it perfectly safe to get groceries. To proclaim space travel perfectly safe is ridiculous and no thinking person would have believed it. It's shameful to see this kind of feel-good propaganda coming from an agency that performs so much hard science.
Anybody remember being a little kid and regarding astronauts with awe and wonder? They were like heroes who explored the greatest frontier imaginable. It was understood that they took risks. They were like fighter pilots except even more badass than that. Space travel was about two things: knowledge and plain ol' balls. I remember being little and thinking that if they can go to the moon years before I was born, imagine what they'll be able to do by the time I'm an adult!
The answer? Absolutely nothing. Sure, there's the ISS but NASA is stagnant and has been for a while now. The ISS isn't new and interesting the way going to Mars or creating a lunar base would be. When did we get so worried about risk that we don't try anything anymore? We send people who are barely considered adults to die for no good reason in the Middle East and we can't send people into space for similar (if not lower) cost? Something's fucked up in this picture.
It is a miracle that curiosity survives formal education. - Einstein
It's not just the life of the astronaut. It's the vehicle and payload as well.
I'm not sure what the various payloads travelling along with, but one of them, Hubble, cost ~$2.5 billion. You might be willing to spend significant amounts of cash to make sure it got into orbit safely, and maintained there, so that that investment wasn't wasted and you wouldn't have to start over from scratch. Ditto for the shuttle or whatever vehicle you are going to use if it's reusable. I think that alters the equation from "2.5 billion for an astronaut".
