Soo koob maqaalka:  Cadeynta in meeraha Mars uu mar ahaa mid la dagan karo ayaa si joogto ah usii kordheysa, maadaama tusaalooyin ay soo aruurisay rover-ka NASA ee Mars Curiosity uu shaaca ka qaaday cunsur muhiim u ah nolosha dhagaxa Martian. saynisyahannadu waxay heleen raadadka maadooyinka nitrogen-ka ee loo yaqaano nitrates, oo ah ilaha muhiimka ah ee nafaqooyinka ee noolaha dhulka ku nool. daahfurkani waa mid cusub oo ku saabsan aragtida ah in kastoo Mars ay tahay mid madhan oo qalalan haatan, waxay ahayd mar la degganaan karo. saynisyahano Nasa ka tirsan oo ku sugan California ayaa cadeymo ka helay Nitrogen-ka meeraha Mars. Baadhitaanka waxaa lagu sameeyay aaladda Curiosity ee lagu falanqeeyo shaybaarka ee Mars. saynisyahannadu waxay heleen nitrates- oo ah isha nitrogen ee nolosha dhulka. Waxay u badan tahay inay ku abuurmeen asteroid ama hillaacyo ku dhacay volcanic plumes. Natiijooyinka waxaa lagu daabacay joornaalka Proceedings ee Akadeemiyada Qaranka ee Sayniska. Qoraalkooda, kooxda cilmi baarista waxay ku sheegeen in Nitrogenku uu tilmaami karo marxaladihii ugu horeeyay ee wareegga Nitrogen ee dusha sare ee Mars. Tani waxay keeni kartaa in ay biochemically heli karo il nitrogen nolosha on Mars. Jawiga aduunka oo ay ku badantahay Nitrogen-ka ayaa sababay in uu noolaado, laakin asalka hawada aan neefsanno ayaa ahaa mid qarsoon mudo dheer. Hada, saynisyahannadu waxay aaminsanyihiin inay heleen jawaabta: in awoodaha dhul gariirka ee keena buuraha iyo volcanoes-ka ay sidoo kale ka dhigeen jawiga mid la dagan karo. cilmiga dhulka ayaa baarayey kiimikada dhul-gariirka waxayna ogaadeen in nitrogenku uu bilaawday inuu soo ururo dhulka 3 bilyan oo sano kahor. Qoraal ay ku daabaceen joornaalka Nature Geoscience, cilmi baarayaasha Carnegie Institution ee Washington ayaa sharaxay bishii Oktoobar 2014 in kiimikada hawada aan neefsanno ay sabab u tahay bilyan sano oo ah habka loo yaqaano photosynthesis, iyo sidoo kale dhaqdhaqaaqa tectonic. Inkastoo saynisyahannadu ogyihiin in dhirta ay mas'uul ka tahay soo saarista oksijiinta, taas oo ka kooban shan meelood meel hawada dhulka, waxa aan la garan karin waxa ku jira nitrogen-ka, kaas oo ka kooban boqolkiiba 80 hawada. <unk>Diiqitaanka maadada 'nitrogen' ee asal ahaan ka soo jeeda meeraha Mars ayaa saameyn weyn ku leh noolaanshaha iyo...
saynisyahano Nasa ka tirsan oo ku sugan California ayaa cadeymo ka helay Nitrogen ku yaalla Mars. Daraasaddan waxaa sameeyay qalabka Curiosity Sample Analysis ee Mars. Saynisyahannadu waxay heleen nitrate-ka oo ah isha nitrogen ee nolosha dhulka. Waxay u badan tahay inay ku abuurmeen asteroid ama hillaacyo ku dhacay volcanic plumes. waxay kordhisaa cadeymaha in meeraha cas uu mar ahaa mid la dagan karo waqtigii hore.
