Amawakawaka ayazi malunga noMars, kodwa uninzi alufumani
Imfihlelo elula ye-Mars - Ububanzi be-Mars bumalunga neekhilomitha ezingama-6800.
IMars ikumgama omalunga ne-1,5 ukusuka elangeni njengoMhlaba.
Ubunzima beMars bumalunga nesinye seshumi sobunzima boMhlaba - Imfihlelo elula ngoMars.
I-Mars Reconnaissance Orbiter (MRO) i-space probe, esetyenziswa yi-arhente yase-US i-NASA, ibijikeleza iplanethi yethu engummelwane wangaphandle ukususela ngo-Matshi ka-2006 kwaye, isebenzisa izixhobo ezintandathu eziqhutywe kule nqanawa ye-Mars, ibonelele izazinzulu ezibandakanyekayo kulo msebenzi. ngedatha entsha malunga neMars phantse yonke imihla.
Ikhamera ephambili ebhodini ye-MRO yikhamera ye-HiRISE eqhutywa yiYunivesithi yase-Arizona, leyo, phantsi kweemeko ezifanelekileyo, inokufikelela kwisisombululo somhlaba weplanethi ukuya kwi-25 centimeters nge-pixel.

Die Ikhamera ye-HIRISEIteleskopu, enobude obuziimitha ezili-12 ubude, idubula iifoto ezinemibala ngesisombululo seesentimitha ezingama-250 ngepikseli nganye ukusuka kumgama weekhilomitha ezingama-25 kwaye ngaloo ndlela isombulula amatye anobubanzi obungaphantsi kwama-50 eesentimitha.
Ifoto enye yi-1,6 yegigapixels ngobukhulu.
Kungenxa yoko le nto ukhetho lomfanekiso olwenziwa ngumphandi lubaluleke kakhulu:
Ngenxa yobuninzi bedatha ngomfanekiso ngamnye, kuphela imifanekiso ye-120 ngeveki inokudluliselwa eMhlabeni kwaye ngenxa yoko kuphela iindawo ezikhethiweyo zomphezulu weMartian ezinokurekhodwa ngesisombululo esiphezulu.

Wikipedia inikeza le ngcaciso ilandelayo ye-Mars - Imfihlelo elula malunga ne-Mars
der mars sisijikelezi-langa sesine kwisijikelezi-langa esibalwa ukusuka elangeni nakummelwane ongaphandle womhlaba. Yenye yeeplanethi ezinjengomhlaba (ezisemhlabeni).
Phantse kwiikhilomitha ezingama-6800, ububanzi bawo bumalunga nesiqingatha somhlaba, kwaye umthamo wawo ukwisinye sesixhenxe somthamo womhlaba. Oku kwenza i-Mars ibe yiplanethi yesibini encinci kwiplanethi yelanga emva kweMercury, kodwa ine-geology eyahlukeneyo kunye neyona ntaba-mlilo iphakamileyo kwisixokelelwano selanga. Kumgama ophakathi kweekhilomitha ezingama-228 ezigidi, ijikeleze amaxesha ayi-1,5 kude nelanga njengoMhlaba.
Ubunzima bukaMars bumalunga nesinye eshumini sobunzima boMhlaba. Ukunyuka komxhuzulane kumphezulu wayo yi-3,69 m/s², ehambelana ne-38% yaloo nto iseMhlabeni. Ngoxinano lwe 3,9 g/cm³, iMars inelona xabiso liphantsi leeplanethi ezisemhlabeni. Ngenxa yoku, umxhuzulane kuyo ungaphantsi kancinci kuneMercury encinci kodwa eshinyeneyo.
