[net.space] Death of IRAS

giles@ucf-cs.UUCP (11/13/83)

Is there any way to "recycle" IRAS?  I seem to recall reading that
IRAS is in orbit 500 miles up, within range of the Shuttle.

Since we have been receiving such excellent data, it seems a shame
we will have to wait nearly a decade for the next satellite.
Especially since the satellite's death will be due to loss of LHe.

I know that NASA requires that a satellite be "alive" before it will
risk an orbiter to retrieve it.  How soon is it until IRAS loses power
and/or control in addition to LHe?  Does it have a docking pin?  Could
NASA add a trip to IRAS onto the end of an existing orbiter mission?

Should we be forming a "SAVE IRAS" mini-pac?

Unfortunately, IRAS is in a near polar
orbit (actually a sun synchronous orbit) and was launched from
Vandenbergh Air Force Base, not Cape Canaveral.  Therefore, until
Shuttle launches from Vandnbergh start to happen (at least several
years), IRAS could not be reached.  In any case, I'm sure that IRAS
would be very difficult to reach in orbit; probably won't fit in the
shuttle bay; and the expense of such a mission would no dobut be better
spent on engineering the successor missions.
