Love this discussion. Here's a tongue-in-cheek take on motivations. For decades, some car manufacturers have been drawn to building race cars, as a way of learning more to improve their consumer vehicles. Or perhaps just for the prestige that it might bring among potential buyers (or because of their love of the engineering involved). Anyway, the occasional automotive company has delved into aircraft, or certainly aircraft parts, for similar motivations.

No robot could recover them, but study of the embryos was considered essential to the science of the relative evolution of birds and reptiles. The expedition was indeed the "worst in the world" and the three men on it barely survived. Cherry-Garrad was still too ill to go with Scott the next summer. Lucky for him

That by the time the expedition returned to civilisation, theory had moved on and the penguin eggs were of no interest to laboratory scientists, has no influence on the value of the expedition, in human terms. It was as heroic, self-sacrificing and inspiring as any astronaut's, and I include Shepard and Apollo 13.

If that doesn't make you think that human exploration is always worthwhile, then ... well you're still human, but you don't get something about us!
Almost all government funded exploration of the Earth has been with the intent of exploiting resources, acquiring territory, or demonstrating political power to other countries. It is only in recent times that we've seen public funds devoted to advancing science, largely for the sake of science. Of acquiring knowledge with little expectation of commercial value. Which is a great thing.

There is plenty of room for human exploration. But where it returns neither commercial opportunity nor significant scientific value (as with most manned space concepts) I see no reason for public funding.

They weren't paying for abstract knowledge. They were paying for a shorter route to the Indies. It was an investment. They hoped for huge commercial success.

That's a poor parallel to sending humans anywhere off the Earth.

What a ridiculous statement. Regardless of whether or not Columbus deserved funding, robots just weren't available then. Chris's argument is that so much more can be done for less using robots. The cost of human space exploration is prohibitive.

At ten times the cost, it would still be worth it.

I can find some logic in both of your arguments. I feel that the majority of endeavors which humanity seeks out have their intrinsic value. Robotic and manned space travel should hold value as much as anything else we’ve set out to do, and succeeded in. I also think the time was right in the 60’s,70’s, etc. for the Government to pave the way where no private enterprise could. And now the time is ripe for private enterprise to take the lead and push forward.

Following the various robotic exploration missions and rovers has been quite exciting, but it will be spellbinding on an entirely different level to follow the first manned Mars exploration crew.

It is ingrained in us (at least some of us) to find out what is just over the next hill, the next mountain, the next planet. And put our ‘boots’ there.

There are a few financially exploitable areas involving space, such as asteroid mining and various commercial satellite markets, such as Earth observation and communications. There is virtually no role for private enterprise in the scientific exploration of the Solar System or the Universe, outside of acting as contractors to public agencies.

A manned mission to Mars would certainly be exciting. But also expensive and useless. It shouldn't be done by the government. And it won't be done by private industry for any purpose other than a vanity project.

Well, that's not terribly useful information except in the context of humans in space.

In any case, it's not that we haven't learned anything. It's about costs and benefits. And IMO the costs of the ISS and other man-in-space efforts have vastly outweighed the benefits.

Yes, there have been great advances due to robotic missions, but I believe the advancements from human missions would likely be in different but equally important areas more directly related to human health, climate change, and the protection of Earth from human actions. Hopefully someday soon we will find out.

I realize all that, but it would be hard to argue that manned missions to other planets wouldn't have been a much better use of (even a modest fraction of) the trillions that have been spent on national defense over the past decades. And I think you could also argue that the technological innovations necessary to accomplish that would have had beneficial repercussions for humanity beyond what has been gained from robotic missions.

It is important to remember that the early space program was all about military might. It was cold war posturing, not science. And boots on the Moon didn't really do much... although it did so at great cost.

Since then, humans have launched hundreds of research missions, visited every planet as well as comets and asteroids, and advanced our knowledge of the Solar System and the Universe immeasurably. In large part because we devoted our limited resources to robotic missions, capable of returning large amounts of information, as opposed to putting boots on other bodies, which is showy, but that's about all.

Your metaphorical usage is valid and so it was nice to say it the way you did.


But ... technically, some boots have recently gone farther. :D
