Artemis is no psyop. It is a rocketry public works program to keep NASA busy, but nobody who does not have a stake in it believes it will amount to much. SpaceX is doing more to get into space than NASA.

The Earth is not flat. The Apollo program went to the Moon. The Van Allen belt does not kill you if you zip through it at many kilometers/second (e.g., it didn't kill the Apollo astronauts). There is no firmament (probes to Mars, Venus, Jupiter, Saturn, Pluto, and out of the solar system).

The Challenger disaster was not caused by spit. It was caused by extreme contraction of an o-ring seal under an adverse temperature environment. The solid motor engineers advised against launch. NASA management thought otherwise. They should have been tried for manslaughter, but weren't.
