Most of the solar system is reachable. No one's talking about starships just yet.Perhaps a realization that the human animal is too fragile and has too short a life span to make space exploration feasible. Weve learned more with Hubble and probes than with manned flights.
The moon project was about Cold War politics, not science. And the science of space is too insignificant to justify the spending of taxpayers money.
But there never was any real space exploration, nor will there ever be.
There was a caveman who once said "we can't cross that mountain, its impossible"
There was some European that said "Don't go West, theres nothing but water and death"
There were people that laughed at the idea of man powered flight
There were people that ridiculed the concept of orbital flight, and making it to the moon
Anything is possible until proven impossible, and proving something impossible is rather difficult.
There are still the physics of time and distance to contend with as long as the biological limitations of man
Distance is measured in light years, the distance light can travel in a year. No matter how fast you think man may eventually be able to travel, it will take years to get there and return. The limitations of man mean you have to provide oxygen, food and water as well as safety
Much of space is best explored by telescope. Why not send a telescope to the end of the galaxy and see what you discover? It is easier and safer to send R2D2 into space than a human being. R2D2 doesn't need room to move around or food or oxygen if he gets destroyed, nobody cares. R2D2 can survive for hundreds of years and still send back data
