The Real Reason for Sending Astronauts into Space 346
Puneet writes "An article on New York Times discussing the need for astronauts for carrying out experiments in space. Too many of the planned experiments depend on crew operations when they could more effectively be done without them. In many cases, the crew is needed only to deploy an autonomous experiment."
But (Score:5, Insightful)
We will always need astronauts to assume certain risks to develop the technology that allows for human exploration of space. The space shuttles and space stations may be necessary to fulfill that mission. However, we need to separate the goal of scientific experimentation from the desire for space exploration. I hope that the unfortunate death of the Columbia astronauts will forever sever the false link that has been created between the two.
Astronauts do not risk their lives to perform scientific experiments in space. They fly to fulfill a much more basic and human desire -- to experience the vastness of space.
We need to seriously rethink our goals. The Shuttle has been around for 1/2 the entire history of man in space. It was being desinged when the Altair was a hit. With modern computer and automation systems, surely the vast majority of research can be performed autonomously. We need a vehicle for this and a seperate vehicle to safely bring people back and forth.
Re:But (Score:5, Insightful)
Of course, its important that the second vehicle doesn't get lost because autonomous systems are more efficient. Sure, they are, but its still important for humans to go to space. Why? Because we want to go. We don't need any other reason. We want to explore and colonize space, even if its inefficient. We need that second vehicle as much as, if not more than, we need the first.

The probes would still do the science, people haven't done any scientific measurements for a while now, since the invention of computers, people don't measure accuratly enough for our level of understanding anymore.

One of the most important things to come out of the Moon landings didn't involve landing on the moon, it was Frank Borman's photograph of earthrise [abc.net.au]. The probe wouldn't think of doing that.
For the scientists, who do care about the science. The people who land on Mars would do so in the knowledge that they are there for about a year until the planets align again, keeping 6 people alive without any external help for 24 months isn't easy (or possible yet). The biosphere project wasn't completely succesful because of the leaky window seals and the double glazing which blocked too much sunlight.
On Mars, we won't have the luxury of pumping more oxygen in, it'll will likely need to be extracted from the ferrous soil or grown in inflatible greenhouses.

Send Expendable Robots, Not Irreplaceable Humans. (Score:3, Interesting)
I love space exploration, but unfortunately, I can't currently love NASA, their political problems has caused them to lose touch with reality. I for one, would willingly support increasing their budget if I thought they were using it to efficiently generate new useful knowledge. Instead of outdated, political, men in space, goals. Wake up NASA! the world has changed, give us results, not Buck Rogers!
Its clear that travel in space is going to be dangerous for a long time. The good news is we dont need to do it much. The dumb problem is NASA believes it must to survive politically. I contend that is a big fat mistake. That mis-assessment is killing some of our best people. We should only ask those with "the right stuff" to go when we have a destination in mind worth the significant and real risk, of losing their lives. I don't include running soap bubble experiments and other PR related feeble excuses to send the first into space. Did we really want to kill the first teacher into space, or the first Israeli, for this nonsense. We all have to realize we are a long way from needing a space station, for anything other than feeding our space opera, sci-fi fantasies. Get real.
Robotics is here. Remote and semi autonomous control is here. NASA management, thinks in terms of the technology it designed the shuttle with thirty years ago. Cheaper, faster, better, off the shelf, works. Yes we will have a few dumb mistakes like Mars Climate Orbiter, so what, No One Died. I read the Mishap Investigation Board report, it was mostly management cost cutting snafu's. The JPL folks navigating the thing were set up to fail by dumb PHB's (yeah they goofed it up too, but overworked, underfunded, folks will make mistakes). Imagine if that same mistake had lost us the first crew en-route to Mars. Robotics produces good, cheap science in space. Robot probes will boldly go where... You get the idea. Sojourner proved this. Beagle2, Spirit and hopefully Opportunity, will probably settle the issue. The long duration surveyors orbiting Mars right now have produced data thats invaluable in assessing that planet, including discovering water, this for a cost, and risk level, unattainable if humans were involved.
I want to see NASA re-focus their budget on on designing and launching small, cheap probes for a host of long duration missions. Robots should be used to explore truly interesting locations. Finally, they should be used to prepare the target environment for any human visit or colonization attempt. No career astronaut should feel obliged to risk long duration space travel, for NASA's PR and politics.
We should boldly go..., when we know there's somwewhere really worth boldly going to..., where the target has been surveyed and prepared for us by our Robots. Then our Astronauts may consider it worth the risk, to go where none have gone before.
Go Opportunity!

8. We can't upload [everything2.org] our minds into robotic shells yet. (GITS!)

6. Robots don't get taxpayers excited.
5. Robots aren't "heroic" enough to inspire kids to grow up to be scientists, etc.
4. Robots just take more jobs away from real flesh-and-blood humans! (Armitage!)

Problem: Shuttle is expensive to fly and is about to become even more expensive. The Columbia Accident Investigation Board has already issued three proposed remedies and it is likely that there will be many more specific actions taken before the Shuttles can return to flight.
Problem: From 2006 until at least 2010, there is no plan on how to support a Crew Return Vehicle that remains attached to ISS in case of an emergency. This gap is due to a combination of diplomatic, financial and technical issues. In 2006, Russia will deliver the last planned Soyuz to ISS. After that time, the US cannot buy more Soyuz due to a law regarding non-proliferation of arms technology to Iran, which Russia has apparently violated. Congress may be able to get around this, but it would still leave the ISS with a maximum permanent crew of 3. No American Crew Return Vehicle is planned until at least 2010.
Problem: With a crew of 3, very little crew time is devoted to actual science: about 20 hours per week, total. The remainder of crew time is spent maintaining ISS and the crew itself (exercise, eating, sleeping, etc).
Problem: Even with a reduced crew size of 3, the Soyuz and Progress vehicles cannot supply enough water for crew needs. That is one reason that the current crew is only 2 men.
Problem: Developing a Shuttle replacement is very costly, and NASA has failed several times already. Each attempt failed for different reasons, but I believe that better funding (and better use of the funding) will be needed to make the next attempt a success.
Problem: NASA is unlikely to gain significant budget increases in the current funding environment (unless they claim to have found terrorist training camps or Iraqi WMD in space). Let's be serious about this.
Fact: NASA spends about $6 Billion per year on Manned Spaceflight (this includes the Space Shuttle Program, the Intl Space Station Program, and a few other items such as range support).
Fact: There is very little fat to cut from NASA without radical reforms that are mostly unrealistic. We can gripe about Fraud Waste and Abuse, but I really don't think anyone can find enough of it (and be able to eliminate it through some reforms) to make a significant difference. One of the biggest problems NASA faces is that it has squeezed the workforce too hard. We can't make them work harder, and it's very hard to make them work smarter (But read on for some ideas on this subject).
So where does that leave us?
If NASA were run just a little more like a business, I think the solution would be to stop focusing on satisfying arbitrary political objectives like "maintain a permanent manned presence in space" and start thinking in terms like "how can we best exploit the imperfect resources we currently have?" and "how can we get out of our current rut and into a sustainable future in space?"
These questions cannot be considered independently. To get out of our current rut, we need to break the cycle of failed NASA attempts to build a new launch system. My sense is that one reason these systems have failed is that they are repeatedly using the same failed approach in developing very risky technological systems.
How does Venture Capital develop risky technological systems? Not by betting on one implementation 10 years in advance, which is what NASA keeps doing. Instead of saying "The next launch system will be Single Stage to Orbit" (X-33), NASA should invest in many promising technologies, similar to the way VCs do. They don't know which of a dozen seed investments will succeed, but at least one should achieve some good results.
How much money can NASA afford to spend on a handful of projects? Not much, so that's where we mu

Human race: growing exponentially
Inevitably: not for long!
This leaves us three options:
- We grow exponentially until there's a collapse, then do it all over again (if we survive). This option sucks.
- We make the transition to a stable, zero growth society. This transition seems politically impossible. Also, a stable, zero growth society sucks (e.g., prepare to give up basic freedoms, etc.). Admittedly it sucks less than a collapse, but it still sucks.
- We expand out of earth, and maintain a growing, open, free society. This is possible, but is expensive.
Some say the last option will never be practical, by doing a simple economical feasability study of mass migration out of earth. There are two answers to this:
- If someone did the same sort of study on the 15th century, it would be obvious mass migration to the Americas isn't economically feasible, either.
- If we don't try, we are certainly doomed to one of the first two options.
So yes, we don't need humans in space for pure scientific exploration. We merely need them for our long-range survival as an open, free society.

Bullshit.
These people are professionals, more knowledgeable of the risks than anyone else, and of the reasons for taking those risks.
Astronauts do not take any greater risk than, say, a soldier in wartime; and who would argue that the human race, in the long run, would benefit more from any given war than from space exploration/colonisation?
I see astonauts like I see soldiers: doing a job that is necessary, that they believe in to the degree that they are willing to risk their lives to do it I think that space exploration is essential; I am happy to fund it with my tax dollars, grateful to those who do it, and, if called upon, would be willing to take those risks myself.
Some pursuits are worth the loss of human life, for the benefit of the species.
