Ososayensi basafuna ukuthola zonke izindawo zeNyanga. Ubuso obufihliwe beNyanga bungobunye obuthakazelisa kakhulu futhi obuyindida ukutholwa. Ukuze uphenye ubuso bayo, i-rover yaseShayina i-Yutu-2 yahlala endaweni ekude yeNyanga ngo-2019. i-chinese rover enyangeni Ukwazile ukuvumbulula izinto eziningi.
Kulesi sihloko sizokutshela mayelana nokunye okutholwe yi-rover yaseShayina eNyangeni.
I-Chinese rover on the Moon kanye nokutholakele kwayo
I-Yutu-2 iyi-rover enamasondo ayisithupha engu-140 kilogram eyingxenye yemishini ye-Chang'e-4 ye-Chinese Space Agency. Ifakwe amathuluzi amane esayensi, okuhlanganisa amakhamera e-panoramic kanye nesistimu yokubona ye-infrared yokuhlonza amagesi nezinto ezikhona emkhathini, ihambe ohlangothini olumnyama lwenyanga kusukela ngoJanuwari 2019.
Ngemva kweminyaka emithathu lolu hambo luqalile, ucwaningo olusha olwanyatheliswa kuyi-Science Robotics luchaza imoto ezimele enqamula inhlabathi ewumhlaba, amadwala e-gelatinous kanye nama-meteorite amancane e-Von Karman crater, eseningizimu nenkabazwe yeNyanga. I-southern hemisphere yenyanga futhi isetshenziswa njengendawo yokufika neyokuhlola ye-Yutu-2.
Ngokusho kwe-Xinhua (isikhungo sezindaba esisemthethweni sasePeople's Republic of China), ukuhamba kwe-rover ohlangothini olukude lweNyanga kuhluke kakhulu endaweni yemvelo yesathelayithi ehloliwe ngaphambi kwemishini ye-Apollo. I-travelogue ye-Yutu-2 ithi i-rover “iyashibilika,” uphawu oluqinisekile lwendawo eshelelayo ebangela ukuba amathayi ayo acwiliswe kancane, kunciphise ukudonsa.
Isebenzisa amathayi njengemishini yokumba, i-Yutu-2 yaqinisekisa ukuthi ukuvumelana kwe-lunar regolith kusuka ku-Von Karman crater kufana kakhulu nesihlabathi esiloam soMhlaba kunesihlabathi esichazwe kahle lapho omishini ye-Apollo efike khona. Abacwaningi ababhekele i-rover iqinisekise ukuthi i-regolith yesifunda inengxenye ephezulu yama-condensates, okubangela izinhlayiya zenhlabathi ezihlala zifana ngisho nalapho ama-rover anesisindo esingaphezu kwamakhilogremu ayi-XNUMX edlula phezu kwawo.
I-Yutu-2 ihlole i-crater engamamitha amabili ukuphakama ngosuku lwesishiyagalombili lwekhalenda yenyanga futhi yathola into eluhlaza okumnyama efana nejeli eyadonsa ukunaka kososayensi. Ngokusekelwe ezithombeni ezithathwe i-rover, i-ejensi yasemkhathini yaseShayina ikholelwa ukuthi izinto ezikhazimulayo zingaba yingxenye yodaka oluvela emthelela noma ukuqhekeka engilazini okudalwe umthelela.
Ubuhlalu bengilazi
I-Chinese rover mission to the Moon yenza okunye ukutholakala okuthakazelisayo ohlangothini olumnyama lwenyanga. Ikhanya othulini olomile olumpunga, ikhamera ye-rover ye-panoramic ithole ama-globule amabili engilazi ekhanyayo.
Nakuba kungase kubonakale njengento yangaphandle, ingilazi ayijwayelekile eNyangeni. Le nto yenziwa lapho izinto ze-silicate zingaphansi kwamazinga okushisa aphezulu, futhi zombili izingxenye zitholakala kalula kumasathelayithi ethu.
Ngokocwaningo, lezi zinhlaka zingaqopha ulwazi ngomlando weNyanga, okuhlanganisa ukuqanjwa kwengubo yayo kanye nezigameko zomthelela. Idatha ehlanganisiwe ibingatholakali ku-Yutu-2, kodwa lezi zimabula zenyanga zemvelo zingaba izinhloso zocwaningo ezibalulekile esikhathini esizayo.
Ngokwe-athikili eshicilelwe ku-Science Alert, esikhathini esidlule enyangeni kwakukhona ukwanda kwentaba-mlilo okwaholela ekwakhekeni kwengilazi yentaba-mlilo. Imithelela evela ezintweni ezincane, njengama-meteorite, nayo idale ukushisa okunamandla okuholele ekwakhekeni kwengilazi. Lesi sakamuva singase sibe ngemva kwama-globules abonwa yi-Yutu-2, ngokwethimba lososayensi eliholwa isazi sokuma kwamaplanethi u-Xiao Zhiyong wase-Sun Yat-sen University kanye ne-Chinese Academy of Sciences.
Kodwa-ke, kunzima ukuqiniseka, ngoba iningi lengilazi etholakala enyangeni kuze kube manje ibukeka ihlukile kunezimbulunga ezitholwe yi-Yutu-2. Kunenani elikhulu lamangqamuzana egazi, kodwa ngokuvamile angaphansi kwemilimitha ngosayizi. Emhlabeni, lezi zindingilizi zengilazi ezincane zadalwa phakathi nemithelela ekhiqize ukushisa okuphezulu kangangokuthi uqweqwe lwancibilika futhi lwakhishelwa emoyeni, ngokusho kwe-athikili Yezaziso Zesayensi. Indwangu encibilikisiwe iyaqina futhi iphinde iwele ebuhlalu obuncane bengilazi.
Ama-spherules e-Yutu-2 makhulu kakhulu, amamilimitha ayi-15 kuya ku-25 ububanzi. Lokho kukodwa akubenzi bakhetheke. Kodwa ukuthi ama-glass sphere afinyelela kumamilimitha angu-40 ububanzi atholakala eduze kweNyanga phakathi nomsebenzi we-Apollo 16. Ama-glass sphere alandelelwa endaweni eseduze, okukholakala ukuthi ama- impact spherules.
Umehluko wokutholwa kwe-Chinese rover eNyangeni
Kukhona ukungaboni ngaso linye phakathi kwemiphumela. NgokukaXiao kanye nososayensi baseShayina, imbulunga ngakolunye uhlangothi ibonakala icwebezela ngokukhazimula kwengilazi. Ngaphezu kwalezi ezimbili ezibonakala zishintshashintsha, bathola ama-globules amane anokukhanya okufanayo, kodwa abakwazanga ukuqinisekisa ukucaca kwawo.
Ama-globules atholwe eduze kwe-crater eseduze, engaphakamisa ukuthi akheke ngesikhathi se-lunar meteorite impacts, nakuba kungenzeka ukuthi zazikhona, zigqitshwe ngaphansi komhlaba, kuphela ukuze zikhishwe umthelela. Kodwa-ke, ithimba likholelwa ukuthi incazelo okungenzeka kakhulu ukuthi lakhiwe ohlotsheni lwengilazi yentaba-mlilo ebizwa ngokuthi i-anorthosite, eyancibilika yabuyela emuva ukuze iguqule indilinga, ama-translucent.
Ngokuvamile, i-morphology engavamile, i-geometry, nendawo yendawo yama-glass sphere kuyahambisana nengilazi yomthelela ye-plagioclase. Lokho kungenza lezi zinto zilingane nenyanga yokwakheka komhlaba okwaziwa ngokuthi ama-tektites: izinto eziyingilazi, ezilingana netshe elincane ezakheka lapho izinto ezivela eMhlabeni zincibilika, zikhishelwa emoyeni, futhi ziqina zibe yibhola. Uma iphinde iwe kufana nenguqulo enkulu yale mikhakha emincane.
Ngokusho kososayensi baseShayina, lesi siphetho asikwazi ukunqunywa ngaphandle kokutadisha ukwakheka kwazo kuqala, kodwa uma zingama- meteorite enyangeni, zingase zibe zivamile endaweni yenyanga. Lokhu kuvula amathuba amangalisayo ocwaningo lwangomuso.
Ngithemba ukuthi ngalolu lwazi ungafunda kabanzi mayelana ne-Chinese rover eNyangeni kanye nokutholwa kwayo.
