The special issue of Astronomy & Astrophysics on the first results from Herschel is now available, with hundreds of papers freely accessible!

I see at least three reasons why this is not doable:
1. unlike the HST, Herschel was not designed to be serviceable 2. you need to use fuel to keep it into the halo orbit or to redirect it somewhere else to wait for servicing. I understand that fuel remaining is not a issue now, but it will become at a certain moment 3. orbital refuelling has been carried out until now with storable, room temperature liquids (hydrazine and water mostly). transfer of cryogenic fuels has yet to be tested, not to speak of the transfer of super-cold (less than 5K IIRC) liquid helium |
