Default HST Reboost

I think one of the problems was that there is a lot of junk in slightly
higher orbits and it would be doubly silly to both risk an orbiter, and the
newly repaired Hubble by doing that, or at least that seems to be one of the
factors. Its a bit of, if it aint needed, why bother sort of thing.

Why not reboost Hubble anyway if propellant permitting?


Good idea...

....After the work on Hubble is completed, Altman and Johnson will
oversee Atlantisâ?T reboost of the telescope to a higher altitude,
ensuring it will survive the tug of Earthâ?Ts gravity for the remainder of
its operational lifetime. A final decision on how much altitude will be
gained by the reboost will be dependent on Atlantisâ?T available
propellant.


The final decision was zero, made before flight. Instead, Atlantis
will lower its own orbit to reduce the risk of MMOD impacts.
