ICuriosity rover ithathe imifanekiso emitsha yamafu amibalabala amnyama kumoya weMars. Ebizwa ngokuba yi-iridescence, le nto yenziwa ngenxa yokusasazwa kokukhanya okuvela ekutshoneni kwelanga yi-aerosols eyomileyo yomkhenkce ekhoyo kwi-atmosphere yaseMartian. Eli yayilixesha lesine loqwalaselo lwelifu lweCuriosity olukwindawo ethile kwaye lubonwa ngamaxesha athile. Ukujongwa kwe-iridescence kumafu amnyama kunika ithuba lokufunda ubungakanani kunye nesantya sokukhula kwamasuntswana kumoya weMartian.
Nge-17 kaJanuwari 2025 (i-4426th Usuku lwe-Martian, okanye i-sol, yemishini yeCuriosity), i-Curiosity rover yathatha imifanekiso emitsha ye-noctilucent (ebengezela ebusuku) okanye amafu amnyama esibhakabhakeni saseMartian enemibala ebomvu neluhlaza. Ebizwa ngokuba yi-iridescence, le nto yenziwa ngenxa yokusasazwa kokukhanya okuvela ekutshoneni kwelanga yi-aerosols yomkhenkce ekhoyo kwi-atmosphere yaseMartian. Ngamanye amaxesha, amafu amnyama enza umbala omhlophe, uvelise i-iridescence, okanye imbonakalo "ye-pearl-mother-pearl".
Eli yayilixesha lesine lokuqwalaselwa kwelifu leCuriosity. Le nto yenzeka ngamaxesha athile ngexesha lokuwa kwangoko kwi-hemisphere esezantsi. ICuriosity rover yaqala ukuthatha imifanekiso ye-iridescence (imibala eqaqambileyo etshintsha ngokuhamba) kumafu eMartian ngo-2019. Amafu e-Twilight aqale ukubonwa kwi-Mars ngo-1997 yi-Pathfinder mission.
I-atmosphere ye-Mars yenziwe ngama-95% e-CO2, 3% N2, 1.6% Ar kunye nemikhondo ye-O2, CO, H2O, CH4, nothuli oluninzi. Kwiindawo eziphakamileyo kunye namaqondo obushushu asezantsi, amafu eMartian enziwe nge-CO enomkhenkce2 okanye umkhenkce owomileyo. La mafu avelisa i-iridescence. Ukujongwa kwe-iridescence kumafu amnyama kunika ithuba lokufunda ubungakanani kunye nesantya sokukhula kwamasuntswana kumoya weMartian.

| umoya ► Yahlala kuMars nge-3 kaJanuwari 2004 ► Unxibelelwano luphulukene ne-22 Matshi 2010. |
| Ithuba ► Yahlala kuMars nge-24 kaJanuwari 2004 ► Unxibelelwano luphulukene ne-10 Juni 2018 |
| Inqwenela ► Yahlala kuMars nge-6 Agasti 2012 ► Ifumaneka kwiMount Sharp eGale Crater, kumazantsi eikhweyitha yaseMartian ► I-rover kuphela eye yabona amafu amnyama enziwe ngomkhenkce wekharbon diokside. Mhlawumbi, oku kungenxa yendawo yayo ekhethekileyo. ► I-Curiosity rover iyasebenza ngoku. |
| Ukunyamezela ► Yahlala kuMars nge-18 kaFebruwari 2021 ► Eyona rover inkulu neyakha yathunyelwa kuMars. ► Ifumaneka kumntla wehemisphere yeJezero Crater ► Umsebenzi ophambili kukufuna iimpawu zobomi bamandulo kunye nokuqokelela iisampulu zamatye nomhlaba ukuze zikwazi ukubuyela eMhlabeni. ► Uphethe inqwelo-ntaka encinane ebizwa ngokuba yi-Ingenuity ephonononga iindawo ezinjengamawa kunye nemingxuma apho i-rover ingenako ukuya khona. ► I-Perseverance rover iyasebenza ngoku. |
| Zhurong ► Yahlala kuMars nge-14 kaMeyi 2021 ► Yacinywa ukuba isebenze nge-20 kaMeyi 2022 |

Kuzo zonke iirovers eziye zawela ngempumelelo kuMars, yiCuriosity kuphela (ekumazantsi eikhweyitha yeMartian) eye yabona amafu amnyama enziwe ngomkhenkce owomileyo. Mhlawumbi, le yimeko ethile yendawo.
Kucingelwa ukuba amaza omxhuzulane we-atmospheric kuMars anoxanduva lokupholisa umoya ngokwaneleyo ukuvumela i-CO.2 ukujiya ube ngumkhenkce owomileyo othi usasaze ukukhanya kwelanga okubangela ukurhawuzelela kwamafu amnyama.
