@ChipmunkErnie Actually, I have been very excited by space exploration since then.
It has been done without sending people, to be sure, but we have been to all the planets ,many of their moons, and a few asteroids and comets. I have found the photos breath-taking.
Sending people means sending life support systems, which makes the craft heavy and expensive. And the amount of science to be learned from astronauts landing at one site and staying for a few days is limited, compared to a long-term robotic lander or even an orbiter, given the kinds of instruments that are available now.
