Cibiyar Binciken Sararin Samaniya ta Kwalejin Kimiyya ta Rasha (IKI RAS) ta ba da rahoton cewa mahalarta a cikin aikin ExoMars-2016 sun buga sakamakon farko na nazarin bayanai daga kayan aikin Trace Gas Orbiter (TGO).
Bari mu tunatar da ku cewa ExoMars aikin haɗin gwiwa ne na Roscosmos da Hukumar Kula da Sararin Samaniya ta Turai, wanda aka aiwatar a matakai biyu. A mataki na farko - a cikin 2016 - TGO orbital module da Schiaparelli Lander tafi Red Planet. Na farko ya sami nasarar tattara bayanan kimiyya, na biyu kuma, alas, ya fado.
A cikin jirgin TGO akwai hadaddun ACS na Rasha da na'urar NOMAD ta Belgium, masu aiki a cikin kewayon infrared na bakan na'urar lantarki. An ƙera waɗannan na'urori don yin rikodin ƙananan abubuwan da ke cikin yanayi - iskar gas waɗanda ba su wuce ƴan barbashi a cikin biliyan ko ma tiriliyan ba, da ƙura da iska.
Ɗaya daga cikin manyan manufofin aikin TGO shine gano methane, wanda zai iya nuna rayuwa a duniyar Mars ko aƙalla ayyukan volcanic mai gudana. A cikin yanayi na Red Planet, kwayoyin methane, idan sun bayyana, ya kamata a lalata su ta hanyar hasken ultraviolet na rana a cikin ƙarni biyu zuwa uku. Don haka, rajistar ƙwayoyin methane na iya nuna ayyukan kwanan nan (na halitta ko volcanic) akan duniya.
Abin takaici, har yanzu ba a sami damar gano methane a cikin yanayin Martian ba. “Ma’auni na ACS, da kuma na’urori na rukunin NOMAD na Turai, ba su gano methane a duniyar Mars ba yayin aunawa daga Afrilu zuwa Agusta 2018. An gudanar da abubuwan lura a yanayin kusufin rana a kowane latitudes," in ji littafin IKI RAS.
Duk da haka, wannan ba yana nufin cewa babu methane kwata-kwata a cikin yanayi na Red Planet. Bayanan da aka samu sun sanya iyaka mafi girma don tattarawar sa: methane a cikin yanayin duniyar Mars ba zai iya zama fiye da sassa 50 a kowace tiriliyan ba. Ana iya samun ƙarin bayani game da binciken a nan.
