“Remember when the famed Hubble Space Telescope was launched without proper testing and it was found the lens were not aligned right? A shuttle flight was needed to give it corrective lens and mirrors.”
Oddly the Hubble had been a scientific bonanza once it was given “corrective lens.” The real hell of it is the taxpayer picked up the price for a contractors error. They ground the mirror to the wrong specs! The contractor should have been bankrupted for the error.
The "work" done on it was not continuous, for one thing.
Can't remember the lack of lack of gravity compensation when the mirror was "built" and "tested" in Earth's gravity.
