re: NASA after 1975
Since 1975, NASA visited all major planets, landed several times on Mars, even landed on Venus and Eros.
It's orbiting Saturn, has orbited Jupiter.
Space telescopes have surveyed the sky like never before.
Sorry, but NASA did go to many places.
More astronauts went to space after 1975 than before.
The space station is a place in space, a destination in weightlessness and high above the ground.
The Moon is also a great place to visit again. But can it be done more sustainably and frequently than a visit or an occupation aboard a space station?
