<p class=MsoNormal style='text-align:justify'>IRAS je bil pionirski satelit, ki
je odprl okno v vesolje infrardeči svetlobi. Izveden je bil v kooperaciji med
ZDA, Nizozemsko in Veliko Britanijo. Projekt je imel veliko izzivov pri rešitvah.
Na primer: hlajenje infrardečih detektorjev pri 2K z uporabo superfluidnega
