You are confusing low orbital launches (LEOs) with actual space flight which ended in 1972 with Apollo 17.
I was there when Nixon, Haldeman, and Ehrlichman took a tour of the San Juan Islands an decided to begin the EPA.
You obviously never had to live the nightmare Nixon created in the western states. Which is understandable - the lefty media pretty much blacked it out.
And the EPA was a nightmare from the start, and OSHA was not much better.
There never was a need for either as government agencies - they are not part of the government’s job nor mandated under the Constitution. If you imagine there was a need, you are very much mistaken - the left simply made a very bad idea worse.
There is no defense for the destruction and major loss of freedom Nixon & Co. made manifest.
