^ Exactly. And what has it amounted to, other than a few brief reconnaissance raids to the Moon? Please don't use the spin-off argument about non-stick frying pans and smartphones. We could have had those things without sending people 400,000 km away.
The people with the same mindset today advocate a direct jump to Mars with no other prep, and for what? Flag planting? At least the private enterprisers aiming at Mars want to achieve a permanent presence there.
Basic human curiosity?
That's what probes are for.
Without goals that push our limits we wouldn't be where we are.
And throughout history those goals have almost always been the quest for new resources, new consumables, new lands to claim and new sources of wealth. It has to remembered that the Voyage of Columbus wasn't launched because anyone was curious about the New World, it was launched because Europe needed a more efficient trade route to India.
However even after several decades the running costs were still enormous.
And will remain so until the demand for launch services significantly increases to the point that launch providers can benefit from an economy of scale. SpaceX, IMO, is already pre-positioning itself for this potential rocket boom, especially if/when they get the Falcon 9R operational.
I don't want to step on your toes but your attitude is a prime example of short sightedness which, if given free reign, could doom us as civilization because we would become content with how we are and wouldn't strive to learn and experience more and if history has shown us anything that stays still is ultimately doomed to fail.
The thing is, the national space programs never accomplished anything concrete in space. Lots of research and high-profile launches, yes, but not much that positively contributed to the technology or the engineering. Most of those gains actually came from government participation in the space INDUSTRY.
And yes, there is and has always been a space industry ever since the first communication satellites were launched. Each of those satellites is basically a privately-owned spacecraft, and each one of them had to be launched into orbit on a rocket that was paid for by private capital. This is overlooked PURELY because all of those satellites are unmanned, but the fact is industry has been active in space to a far greater degree than governments have.
Manned spaceflight is the hobby of governments only because it has never been profitable: since nobody lives in space, nobody's doing business up there, and since nobody's doing business up there, nobody lives there. It's a catch-22. The simple way OUT of that Catch-22 is to give a substantial number of people an excuse (even a flimsy pretense) to live there, and then help them find something profitable to do once they're up there. The current effort with COTS and ccdev aims to use the ISS for this purpose: an orbital science lab is an ideal customer for commercial crew transport and commercial launch services.
