Ukushisa Kwelanga Kungabangela Iziphepho Zothuli ku-Mars

 Ithimba lososayensi, okuhlanganisa noDkt. Germán Martínez we-Universities Space Research Association, lisanda kushicilela ucwaningo Izinqubo ze-National Academy of Sciences. Lolu cwaningo lubonisa ukuthi kukhona ukungalingani kwamandla esizini enanini lamandla elanga amuncwa futhi akhishwa i-Mars okungenzeka ukuthi iyimbangela yeziphepho zothuli futhi engadlala indima ebalulekile ekuqondeni isimo sezulu nesimo sezulu seplanethi ebomvu. 

Isabelomali samandla akhazimulayo (igama elibhekisela esilinganisweni samandla elanga iplanethi ewathatha elangeni bese iwakhipha njengokushisa) yeplanethi iyimethrikhi eyisisekelo. Ngokusekelwe kulokho okuphawulwe emisebenzini eminingi, iqembu lososayensi lanikeza isithombe somhlaba wonke ngesimo sezulu se-Mars. Izilinganiso ezivela ku-Mars Global Surveyor ye-NASA, i-Mars Science Laboratory's Curiosity rover, kanye nemishini ye-InSight kuveza ukuhluka okuqinile kwesizini kanye nokuhamba kwansuku zonke kwamandla akhishiwe e-Mars.  

“Okunye okutholwe okuthakazelisa kakhulu ukuthi amandla engeziwe—amandla amaningi amuncwa kunalawo akhiqizwayo—kungaba enye yezindlela ezidala iziphepho zothuli kuyi-Mars,” kusho u-Ellen Creecy, umbhali oholayo wocwaningo.¹ kanye nomfundi ofundela ubudokotela eNyuvesi yaseHouston, eTexas.

"Imiphumela yethu ekhombisa ukungalingani kwamandla okuqinile iphakamisa ukuthi amamodeli ezinombolo zamanje kufanele abuyekezwe, njengoba lezi zivame ukucabanga ukuthi amandla akhazimulayo e-Mars alinganisela phakathi kwezinkathi zonyaka ze-Mars," kusho uDkt. Germán Martínez, USRA Staff Scientist e-Lunar and Planetary Institute (LPI). ) kanye nombhali wephepha. "Ngaphezu kwalokho, imiphumela yethu igqamisa ukuxhumana phakathi kwezivunguvungu zothuli nokungalingani kwamandla, futhi ngaleyo ndlela inganikeza imininingwane emisha mayelana nokuvela kweziphepho zothuli ku-Mars."

Kulolu cwaningo, ithimba lososayensi lisebenzise okuphawulwe kumasathelayithi e-martian, ama-landers, nama-rovers ukuze lilinganisele amandla akhishwa i-Mars emhlabeni wonke njengomsebenzi wesizini, okuhlanganisa nezikhathi ezinothuli lomhlaba wonke. Bathole ukuthi kukhona ukungalingani kwamandla okuqinile okungu-~15.3 % phakathi kwezinkathi zonyaka ze-Mars, okukhudlwana kakhulu kunaseMhlabeni (0.4%) noma i-Titan (2.9%). Baphinde bathola ukuthi phakathi nesiphepho sothuli esizungeze iplanethi i-Mars ngo-2001, amandla aphumayo emhlabeni wonke ehle ngo-22% emini kodwa anyuke ngo-29% ebusuku.

Imiphumela yalolu cwaningo, ihlangene namamodeli ezinombolo, inamandla okuthuthukisa ukuqonda kwamanje kwesimo sezulu se-martian kanye nokujikeleza komkhathi, okubalulekile ekuhloleni komuntu i-Mars esikhathini esizayo futhi mhlawumbe kungase kubikezele izinkinga zesimo sezulu soMhlaba.
