If the shuttle crew can repair other satellites, why can't they
refill the IRAS helium supply and keep it running? It certainly
looks to be worth it, and why throw it away and not have the
benefits of such a useful device until, as the news story indicated,
a "next-generation" version is launched in the 1990's?

I would think that the IRAS could be refilled every n missions, or
a big helium tank could be attached to it so it could run for much
longer between fillings. Or are other parts of the detector degenerating
so that there is more to it than the helium running out?
