Is a retrieval flight cost effective? I am thinking the cost of the
retrieval flight is about as much as the cost of the hardware retrieved.
It
might be cheaper to just build another satillite than to perform a
retrieval. Not to mention the risk to humal life to do the retrieval..

If they tried to build another Hubble, the lowest cost contractor,
(probably Walmart) would end up spending two years "accurately"
grinding a mirror, fully certify it as having 20-20 vision and we'd be
right back in 1990 again.

Actually when Hubble was built, another contractor built another mirror as a
backup and according to this article, it's now on loan to the Smithsonian's
National Air and Space Museum.
