Given the Centaur's propellants (LH2 and LOX), I would be surprised if either of those had lasted 10 years, even without any attempt to passivate the the stage. The RCS uses a hydrazine monopropellant, which could probably survive if it weren't dumped (the Wikipedia article says 340 pounds are carried, split between two bladder tanks). Since I expect they would have attempted to dump the propellants, if that were successful, there shouldn't be propellants left over. _______________________________________________ Seesat-l mailing list http://mailman.satobs.org/mailman/listinfo/seesat-lReceived on Mon Apr 03 2017 - 16:09:07 UTC
