Ukusukela ngo-1976, iisampulu zokuqala zamatye enyanga zibuyele eMhlabeni.Ngomhla we-16 kuDisemba, isiphekepheke saseTshayina iChang’e-5 sabuyisa malunga neekhilogram ezi-2 zemathiriyeli emva kotyelelo olukhawulezileyo kumphezulu wenyanga.
I-E-5 yahlala enyangeni ngomhla woku-1 kuDisemba, yaza yanduluka kwakhona ngoDisemba 3. Ixesha lesiphekepheke lifutshane kakhulu ngenxa yokuba sisebenza elanga kwaye asikwazi ukumelana nobusuku oburhabaxa obukhanyiswa yinyanga, obunobushushu obungaphantsi ko-173°C.Ikhalenda yenyanga ithatha malunga neentsuku ezili-14 zomhlaba.
“Njengesazinzulu senyanga, oku kuyakhuthaza ngokwenene kwaye ndixolile kuba siye sabuyela phezu kwenyanga okokuqala phantse kwiminyaka engama-50.”utshilo uJessica Barnes weYunivesithi yaseArizona.Umsebenzi wokugqibela wokubuyisela iisampulu ezivela enyangeni yayiyiSoviet Luna 24 probe ngo-1976.
Emva kokuqokelela iisampulu ezimbini, thatha isampuli enye emhlabeni, kwaye emva koko uthathe isampuli enye malunga neemitha ezi-2 ngaphantsi komhlaba, emva koko uzilayishe kwisithuthi esinyukayo, uze uphakamise uphinde ujoyine i-orbit yesithuthi sobuthunywa.Le ndibano sisihlandlo sokuqala ukuba iziphekepheke ezibini zerobhothi zizenzele ngokwazo ngaphandle komjikelezo woMhlaba.
I-capsule equlethe isampuli idluliselwe kwisiphekepheke sokubuya, esashiya umjikelezo wenyanga wabuyela ekhaya.Xa iChang’e-5 isondela emhlabeni, yakhupha icapsule, eyatsiba iphuma emoyeni ngaxeshanye, njengelitye elitsiba phezu kwechibi, licotha ngaphambi kokuba lingene emoyeni lize lifake iparashute.
Ekugqibeleni, i-capsule yafika kwi-Inner Mongolia.Ezinye ze-moondust ziya kugcinwa kwiYunivesithi yaseHunan e-Changsha, e-China, kwaye enye iya kuhanjiswa kubaphandi ukuze bahlalutye.
Olunye lolona hlalutyo lubalulekileyo oluya kwenziwa ngabaphandi kukulinganisa iminyaka yamatye kwiisampulu kunye nendlela abachatshazelwa ngayo yimeko yendawo ngokuhamba kwexesha."Sicinga ukuba indawo apho i-Chang'e 5 yahlala khona imele enye yezona zinto zincinci zihamba phezu kwenyanga," utshilo uBarnes."Ukuba singanciphisa ngcono iminyaka yendawo, ke sinokubeka imiqobo engqongqo kwiminyaka yayo yonke inkqubo yelanga."
