This might be one of the few times I agree with AJ, but he is right.
Manned space flight is only a small part of our exploration of space, with decades of sending probes and robots to several dozens of missions. We sent a ship to Pluto, a 3 BILLION mile flight, to be in the right place for a 36-hour window to photograph it. We have two ships orbiting the sun. We have others exploring Mercury, Jupiter, Mars and Venus and their moons, besides the ones you see on the surface of our moon and Mars.
We landed on and sampled an asteroid, for Christ’s sake.
We have extremely sophisticated telescope, radiation, radio wave and microwave systems on duty 24/7 and our second space-based telescope recording our universe.
Apollo 8 is often overshadowed by other moon missions, but consider that in 1968 it was the first time we left this planet to go somewhere else. That was only 66 years ago.
Voyager I and II are still transmitting as they continue to fly across the universe. How do you like them apples?
