Kua Iridium kua whakamahia i roto i te radioiisotope generators thermoelectric o waka ātea unmanned pērā i te Voyager, Viking, Pioneer, Cassini, Galileo, ko New Horizons. Iridium i whiriwhiria ki te encapsulate te plutonium-238 i roto i te generator wahie no te mea e taea e ia te tu i te pāmahana whakahaere o runga ki te 2000 ° C me mo tona kaha nui. Ko tētahi atu whakamahi pānga X-ray optics, rawa X-ray telescopes. E pania ana te whakaata o te Chandra X-ray Observatory ki te apa o 60 nm matotoru o te iridium. Iridium kua kitea ki te whiriwhiri pai mō te whakaata X-rays, i muri i te papa imaging whānui o ngā tawhā. Kua whakamahia hoki te iridium i roto i te mata o te X-radium i raro i te pāmahana tiketike, e tika ana ki te kia whakamahia i raro i te pāmahana tiketike, he pai ake i roto i te mata o te iridium i raro i te mata o te X-radium.
