U fiirso qoraalka hoose ka dibna ka jawaab su'aasha kadib isla luqadda qoraalka:  Gelitaanka: In kasta oo biraha kale loo isticmaali karo in lagu daboolo walxaha loo adeegsado SEM, Iridium waa dahaadhka la doorbido marka shaybaarada lagu baari doono cabirro muuqaal oo kala duwan. Iridium waxaa loo adeegsaday koronto-dhaliyayaasha korantada ee radioisotope-ka ee maraakiibta bannaanka ee aan duuliyaha lahayn sida Voyager, Viking, Pioneer, Cassini, Galileo, iyo New Horizons. Iridium waxaa loo doortay in lagu daboolo shidaalka plutonium-238 ee koronto-dhaliyaha maxaa yeelay wuxuu u adkeysan karaa heerkulka hawlgalka illaa 2000 ° C iyo xooggiisa weyn. Isticmaal kale wuxuu ku saabsan yahay X-ray optics, gaar ahaan muraayadaha raajada ee X-ray. Muraayadaha Chandra X-ray Observatory waxaa lagu daboolay lakab iridium ah oo dhumucdiisuna tahay 60 nm. Iridium wuxuu cadeeyay in uu yahay doorashada ugu fiican ee ka tarjumeysa raajada X kadib markii nickel, dahab, iyo platinum sidoo kale la tijaabiyay. Lakabka iridiyamka, oo ay ahayd inuu ahaado mid siman ilaa dhowr atomo, ayaa lagu dabaqay iyadoo lagu shubay uumiga iridiyamka oo ku jira faaruq sare oo ku yaal lakabka aasaasiga ah ee chromium. Iridium waxaa loo isticmaalaa fiisikiska walxaha yaryar si loo soo saaro antiprotons, oo ah nooc ka mid ah antimatter. Antiprotons waxaa lagu sameeyaa iyadoo la toogto shaashad proton ah oo xoogan oo bartilmaameed u ah beddelidda, taas oo u baahan in laga sameeyo qalab cufnaanta sare leh. Inkastoo tungsten loo isticmaali karo halkii, iridium wuxuu leeyahay faa'iidada xasiloonida wanaagsan ee hoos u dhaca hirarka shoogga ee ay keento heerkulka kor u kaca sababtoo ah raajada dhacday.  Su'aal: Waa imisa dhumucda lakabka iridiyamka ee muraayadaha Chandra X-ray Observatory?
