ua faaaogaina Iridium i le radioisotope generators thermoelectric o unmanned vaʻalele e pei o le Voyager, Viking, Paionia, Cassini, Galileo, ma New tafailagi. na filifilia Iridium e encapsulate le plutonium-238 i le afi afi afi ona e mafai ona tetee atu i le faagaoioia vevela o le oo atu i le 2000 ° C ma ona o lona malosi tele. O le isi faaaogaina e faatatau i X-ray optics, aemaise lava X-ray telescopes. ua coated le faata o le Chandra X-ray Observatory i se vaega o le 60 nm mafiafia. ua faamaonia Iridium e avea ma filifiliga sili ona lelei mo le atagia mai o X-rays, ina ua uma ona suesueina i se vaega tele o parameter imaging. na faaaogaina foi Iridium i le faatupuina o le eletise eletise radioisotope o unmanned vaʻalele e pei o le Voyager, Viking, paionia, Cassini, Galileo, ma New tafailagi.
