Ngentsimbi ye-7:38 emva kwemini ngomhla wesi-4 kweyeSilimela, iChang'e 6 ephethe iisampulu zenyanga yasuka ngasemva kweNyanga, kwaye emva kokuba injini ye-3000N isebenze malunga nemizuzu emithandathu, yaphumelela ukuthumela imoto yokunyuka kwi-orbit ecwangcisiweyo.
Ukususela nge-2 ukuya kwi-3 kaJuni, iChang'e 6 igqibe ngempumelelo ukusampula okukrelekrele nokukhawulezayo kwiSouth Pole-Aitken (SPA) Basin kwicala elikude lenyanga, yaza yagquma yaza yagcina iisampulu zenyanga ezixabisekileyo kwicala elikude kwisixhobo sokugcina esithwalwa sisithuthi esinyukayo ngendlela emiselweyo. Ngexesha lenkqubo yokuthatha iisampulu kunye nokugquma, abaphandi, kwilebhu yomhlaba, balinganisa imodeli yejografi yendawo yokuthatha iisampulu kwaye balinganisa ukusampula ngokusekelwe kwidatha yesixhobo sokufumanisa esidluliselwe sisathelayithi ye-Queqiao-2 relay, enika inkxaso ebalulekileyo yokwenza izigqibo kunye nokusebenza kwesampulu kwiinkalo ezahlukeneyo.
Ukuthatha iisampulu ngobuchule yenye yezona zinto ziphambili ezidibanisa umsebenzi weChang'e 6. Le detector yamelana novavanyo lobushushu obuphezulu ngasemva kwenyanga yaza yaqokelela iisampulu zenyanga ngeendlela ezimbini: ukubhola ngezixhobo zokubhola kunye nokuthatha iisampulu etafileni yengalo yerobhothi, ngaloo ndlela yafumana iisampulu ezizenzekelayo ezinamachaphaza amaninzi kunye neentlobo ngeentlobo ezahlukeneyo.
Ikhamera yokufika, ikhamera ye-panoramic, isixhobo sokufumanisa ulwakhiwo lomhlaba wenyanga, isixhobo sokuhlaziya i-lunar mineral spectrum kunye neminye imithwalo yokuhlawula eyenziwe kwi-Chang'e 6 lander yayidla ngokuvulwa, kwaye uphando lwesayensi lwenziwa ngokwesicwangciso, ludlala indima ebalulekileyo kwimisebenzi yokuhlola yesayensi efana nokufumanisa nokufunda i-topography yomphezulu wenyanga kunye neenxalenye zeminerali, kunye nokufumanisa isakhiwo esingaphantsi kweNyanga. Ngaphambi kokuba i-probe igqojwe ukuze ithathwe iisampulu, i-Lunar Soil Structure Explorer yahlalutya yaza yagweba isakhiwo somhlaba wenyanga ongaphantsi komhlaba kwindawo yesampulu, inika isalathiso sedatha sokufumana iisampulu.
Imithwalo yemihlaba yamazwe ngamazwe eyayithwalwa yi-Chang'e 6 lander, njengesixhobo se-negative ion esinikezelwe yi-ESA kunye nesixhobo sokulinganisa i-radon ye-Lunar yaseFransi, yayisebenza ngokuqhelekileyo kwaye yenze imisebenzi yesayensi ehambelanayo. Phakathi kwazo, isixhobo sokulinganisa i-radon ye-Lunar yaseFransi savulwa ngexesha lokudluliselwa koMhlaba neNyanga, isigaba se-circumlunar kunye necandelo lomsebenzi womphezulu wenyanga; kwaye isixhobo se-negative ion esinikezelwe yi-ESA savulwa ngexesha lomsebenzi womphezulu wenyanga. I-Italian passive laser retroreflector efakwe phezu kwe-lander yaba yindawo yokulawula indawo yokulinganisa umgama ngasemva kweNyanga.
Iflegi ebomvu eneenkwenkwezi ezintlanu eyayithwalwe yiChang'e 6 lander yavulwa ngempumelelo kwicala elikude lenyanga emva kokuba kugqityiwe ukulandwa kwetafile. Eli lixesha lokuqala iTshayina ukubonisa iflegi yayo yesizwe ngokuzimeleyo nangokuguquguqukayo kwicala elikude lenyanga. Iflegi yenziwe ngohlobo olutsha lwezinto ezidityanisiweyo kunye nenkqubo ekhethekileyo. Ngenxa yeendawo ezahlukeneyo zokufika kwenyanga, inkqubo yokubonisa iflegi yesizwe yeChang'e 6 ilungisiwe kwaye iphuculwe ngokusekelwe kumsebenzi weChang'e 5.
Kuyaqondakala ukuba le flegi yenziwe ngabaphandi abaneminyaka engaphezu konyaka besenza uphando, besebenzisa ubuchwepheshe bokudweba i-basalt lava, inokumelana nokugqwala okunamandla, ukumelana nobushushu obuphezulu, ukumelana nobushushu obuphantsi kunye neminye imisebenzi emihle kakhulu. Ilitye le-basalt elivela kwi-Hebei Weixian, i-basalt ibuyela kwi-coil, yanyibilika emva kokuyitsala ibe yi-hairline diameter emalunga nesinye kwisithathu see-filaments, yaze yaphothwa yaba ngumgca, olukiweyo lwaba ngelaphu.
Xa kuthelekiswa nokusuka emhlabeni, isithuthi sokunyuka iChang'e 6 asinayo inkqubo yenqaba yokuqalisa esisigxina, kodwa sisebenzisa i-lander njenge "nqaba yexeshana". Xa kuthelekiswa nokusuka kweChang'e-5 ukusuka kumphezulu wenyanga, ukusuka kweChang'e-6 ukusuka ngasemva kwenyanga akunakuxhaswa ngokuthe ngqo ngokulinganisa nokulawula umhlaba, kwaye kufuneka incediswe yisathelayithi ye-Queqiao-2 relay ukuze ikwazi ukubeka indawo ezimeleyo kunye nokulungisa isimo sengqondo ngoncedo lweemvakalelo ezikhethekileyo ezithwalwa yiChang'e-6, nto leyo eyenza kube nzima nangakumbi ukuyisebenzisa le projekthi. Emva kokutsha nokusuka, iChang'e 6 yadlula kumanqanaba amathathu okunyuka ngokuthe nkqo, ukulungiswa kwesimo sengqondo kunye nokufakwa kwe-orbital, kwaye yangena ngempumelelo kwi-orbit yokubhabha ecwangcisiweyo.
Emva koko, i-ascender iza kudibana ize imise i-docking kwi-lunar orbit kunye ne-orbiter kunye ne-returner indibaniselwano zilinde kwi-circumlunar orbit kwaye zidlulisele iisampulu zenyanga kwi-returner; i-orbiter kunye ne-returner indibaniselwano ziza kubhabha zijikeleze iNyanga, zilinde ixesha elifanelekileyo lokubuya ukuze zenze uthutho lwenyanga nomhlaba, kwaye kufutshane noMhlaba i-returner iza kuthwala iisampulu zenyanga ize iphinde ingene emoyeni, kunye nesicwangciso sokufika kwindawo yokufika yaseSiziwangqi e-Inner Mongolia.
Luluphi uphando oluza kwenziwa kumhlaba wenyanga obuya kwisampuli yeChang'e 6's lunar back? Ziziphi iimpawu zeAitken Basin apho iChang'e 6 yafika khona ukuze isampuliwe ngeli xesha? Kutheni le ndawo yakhethwa ukuze kuthathwe isampuli yenyanga?
Kuxelwe ukuba usekela-mphathi we-Chang'e 6 mission engineering, usekela-mphathi we-designer ground application system, umlawuli oyintloko uLi Chunlai: I-Chang'e 6 ngokwenene yi-Chang'e 5 backup, sinethemba lokukhetha indawo elinganayo, sikhethe umva we-South Pole yenyanga - i-Aitken Basin ekhethiweyo kwangaphambili. Sinethemba lokufumana isampuli yokuqala yecala elikude lenyanga kubantu, kwaye sinomdla wokuba isampuli yecala elikude lenyanga yahluke kangakanani kwicala elingaphambili.
Iisampulu ezivela eNyangeni zixabiseke kakhulu, kwaye iisampulu ezivela kwicala elikude lenyanga ziyimfihlakalo kakhulu. I-Chang'e 5 ibuyise iigram ezili-1,731 zeesampulu, kwaye iTshayina ngoku isasaze iisampulu ezingama-258 zenyanga ngamaqamza amathandathu kumaqela ophando lwezenzululwazi amakhulu, kwaye ifumene iziphumo ezibalulekileyo kwiindawo ezininzi ezifana nokwakheka kwenyanga, ukuvela kwendalo kunye nokusetyenziswa kwezixhobo, njengokuqinisekisa ukuba ubudala bebasalt encinci yenyanga buyiminyaka ezibhiliyoni ezi-2, kunye nokuhlehlisa ukuphela komsebenzi wentaba-mlilo yenyanga malunga neminyaka ezizigidi ezi-800. Ubudala bebasalt encinci yeNyanga buqinisekisiwe ukuba buyiminyaka ezibhiliyoni ezi-2, kwaye ukuphela komsebenzi wentaba-mlilo yeNyanga kwahlehliswa malunga neminyaka ezizigidi ezi-800.
Ngeli xesha, iChang'e 6 iza kubuyisa iisampulu ezivela kwicala elikude lenyanga, kwaye loluphi uphando olutsha oluza kwenziwa? Ngawaphi amalungiselelo enziwe yiLunar Sample Laboratory?
ULi Chunlai, uSekela-Myili oyiNtloko weChang'e 6 Mission Engineering kunye noMlawuli oyiNtloko weNkqubo yoSetyenziso loMhlaba: Ukwakheka kwamatye eesampuli eziqokelelwe yiChang'e 6 kunokwenzeka ukuba kube zizinto ze-basaltic, kwaye kwindawo yokufika, sibona ukuba kukho ezinye iintlobo ezininzi zezinto ezinokuthi zikhutshwe kwezinye iindawo. Ezi zifundo zinokuchaza iimpawu zeesampuli ezivela ekumbiweni okunzulu kwisitya esikhulu kangaka sesangqa esenziwe kwinkqubo yelanga yokuqala. Oku kuya kuba negalelo elikhulu ekufundeni ngokuvela kweNyanga kwasekuqaleni, kwanasekufundweni kwembali yokuqala yokuvela koMhlaba. Ukuba isampulu indala kangakanani kufuneka ihlalutywe. Nangona kunjalo, ukwakheka kwamatye ayo kunye nobudala bokwakheka kwayo kufuneka kwahluke kokwesampulu eqokelelwe yiChang'e-5, ekufuneka ifundwe kwaye ihlalutywe ngakumbi.
ILabhoratri yeSample yeLunar (LSL) yenze onke amalungiselelo okufumana, ukucubungula, ukulungiselela, ukuhlalutya kunye nokuphanda iisampulu, kwaye ilinde kuphela ukuba iisampulu zeChang'e 6 zifike kwiLaboratri, ukuze sikwazi ukwenza uphando olunzulu lwesayensi.
