Actually it is NASA Administrator Sean O'Keefe who decided that fixing
Hubble is not worth an astronaut's life or losing another shuttle. A
board of investigation was set up to determine the risks involved. I
personally think the risk is not that high and that a human service
mission should go ahead as planned.
Hubble is a sentimental thing.
At least once a year for the last five years I have read of a new
telescope coming on line that advertises having a better resolution
than Hubble.
I thought the reason was scientific investigation not sentimentality.
We are getting better resolution than Hubble. We do not have launchers
which can put a large enough mirror in orbit to compete with the earth
telescopes.
Is there a rational reason for saving Hubble? In fact, is there a
rational reason for continuing work on its replacement in orbit? Can
the same dollars produce even better earth based telescopes?
Resources are finite and NASA has them for space telescopes. THe
money does not transfer to earth telescopes so it is not a tradeoff.
Infrared, ultraviolet, and x-rays don't get through the Earth's atmosphere
very well. (Why do you think visible light is visible?)
