<snip>PS like the idea of returning the Hubble to Earth, in 15-20 years time...
... (is Hubble Telescope a him or a her)?
(But remember, never call an orbiter an "it!")
Thanks for the article, Chris. Hubble - and the ISS - are living proof of the value the Space Shuttle provided to the space program. Everyone who was involved in the shuttle program should really be proud of that legacy.
