Absolutely, the system I've proposed, with it's $475 million dollar saving to
the Amercian tax payer could also be used for a targeted de-orbit. The key
word being "targeted de-orbit" which means you are dumping HST where you want
it to come down, not where natural decay will pluck it from the sky at random.
But if we can dock a modified Progress to the back of HST from an equatorial
(or even the new Soyuz pads at Kourou which will be on line by then), I sure
the Russians would be able to figure out how to put a down sized Streka (their
man operated telescoping arm crane) on the orbital module of a Soyuz so that
they could fly a small components repair mission. BTW that is strickly
hypothetical as I do Not have the mass figures for such an add on calculate just how
much cargo can be added as you will now becarrying the weight of a descent
cabin in the middle instead of extra fuel tanks that were in the mid section of
the Progress that de-orbited Mir.
Food for thought.
