Kusukela ngo-1976, amasampula okuqala enyanga abuyele eMhlabeni afikile.Ngo-December 16, umkhumbi-mkhathi waseChina i-Chang'e-5 wabuyisa cishe amakhilogremu angu-2 wezinto ezibonakalayo ngemva kokuvakashela ngokushesha endaweni yenyanga.
I-E-5 yahlala enyangeni ngo-December 1, yaphinde yenyuka ngo-December 3. Isikhathi salo mkhumbi-mkhathi sifushane kakhulu ngoba sisebenza elanga futhi asikwazi ukumelana nobusuku obunzima obukhanyiswa yinyanga, obunezinga lokushisa eliphansi njenge -173°C.Ikhalenda lenyanga lithatha cishe izinsuku eziyi-14 zomhlaba.
“Njengososayensi wenyanga, lokhu kuyakhuthaza ngempela futhi ngikhululekile ngokuthi sesibuyele ebusweni benyanga ngokokuqala ngqá cishe eminyakeni engu-50.”kusho uJessica Barnes waseNyuvesi yase-Arizona.Umsebenzi wokugcina wokubuyisa amasampula avela enyangeni kwakuyi-Soviet Luna 24 probe ngo-1976.
Ngemva kokuqoqa amasampula amabili, thatha isampula elilodwa phansi, bese uthatha isampula eyodwa endaweni engaba amamitha angu-2 ngaphansi komhlaba, bese uwalayisha emotweni ekhuphukayo, bese uyaphakamisa ukuze ujoyine kabusha umzila wemoto yemishini.Lo mbuthano ngokokuqala ngqá ukuthi imikhumbi-mkhathi emibili eyirobhothi ibe nokuma okuzenzakalelayo ngaphandle komjikelezo woMhlaba.
I-capsule equkethe isampula yadluliselwa kumkhumbi-mkhathi obuyayo, owashiya umjikelezo wenyanga wabuyela ekhaya.Lapho i-Chang'e-5 isondela emhlabeni, yakhipha i-capsule, eyagxuma iphuma emkhathini ngesikhathi, njengetshe eligxuma phezu kwechibi, lehla ijubane ngaphambi kokuba lingene emkhathini bese lifaka ipharashute.
Ekugcineni, i-capsule yahlala e-Inner Mongolia.Ezinye ze-moondust zizogcinwa e-Hunan University e-Changsha, e-China, kanti enye izosatshalaliswa kubacwaningi ukuze bayihlaziye.
Okunye ukuhlaziya okubaluleke kakhulu okuzokwenziwa abacwaningi ukukala iminyaka yamadwala kumasampula kanye nokuthi athintwa kanjani imvelo yesikhala ngokuhamba kwesikhathi."Sicabanga ukuthi indawo lapho i-Chang'e 5 ihlezi khona imele enye yezindawo ezincane kakhulu ezigeleza phezu kwenyanga," kusho uBarnes."Uma singanciphisa kangcono iminyaka yendawo, singabeka imingcele eqinile eminyakeni yawo wonke amasistimu sonozungezilanga."
