Iridium yakashandiswa mu radioisotope thermoelectric generators yeunmanned spacecraft yakadai seVoyager, Viking, Pioneer, Cassini, Galileo, uye New Horizons. Iridium yakasarudzwa kuvhara plutonium-238 mujenareta yemafuta nekuti inogona kumira tembiricha yekushanda inosvika 2000 ° C uye nekuda kwesimba rayo rakakura. Chimwe chishandiso chine chekuita neX-ray optics, kunyanya X-ray telescopes. Magirazi eChandra X-ray Observatory akafukidzwa ne60 nm gobvu re iridium. Iridium yakaratidza kuve sarudzo yakanakisa yekuratidzira X-rays, mushure meplateinum, uye iridium yakashandiswawo mune radioiisotope thermoelectric jenareta dzisina vanhu senge Voyager, Viking, Pioneer, Cassini, Galileo, uye New Horizons.
