Kuyinyani ukuba kungekudala i-NASA yathetha esidlangalaleni kuRhulumente wase-United States uhlobo lwesicwangciso esingxamisekileyo sokuba amaMelika, kubandakanya bonke abantu abasemhlabeni, kufuneka basebenzisane ekuphunyezweni kwawo okuqhubela phambili ukuze baphumelele, ngendlela enokwenzeka, ukuze baphile iplanethi yethu phambi a ngaphezulu kokungqubana kwe-asteroid enkulu ngokuchasene noMhlaba ngokwawo.
Ngoku lixesha lokuthetha malunga nomsebenzi weHera apho izazinzulu kunye nabaphandi abavela kwi-ESA, i-European Space Agency, basebenza khona. Ngokomntu, kufuneka ndivume ukuba iinjongo zeHera zijolise, njengokuba kunjalo kwimephu yesenzo ecwangciswe yi-NASA, ukubeka isisombululo kwinto yokuba i-asteroid okanye olunye uhlobo lwento enkulu lubetha uMhlaba, ngeli xesha inyani kukuba e-ESA bayaqhubeka kancinci kuba, phakathi kwezicwangciso zabo, kukufunda enye yezi zinto kwaye fumanisa eyona ndlela yokuyiphambukisa kwindlela yayo.
I-ESA sele isebenza kuphuhliso lwe-Hera mission
Ukuya kwinkcukacha ezithe kratya, yeyiphi i-ESA esebenza ngayo sisicwangciso esineenjongo eziphambili kukuthumela uhlobo oluthile lwenkqubo ye-asteroid kanambambili ngo-2026. Ngalo mzuzu i-mission sele ikwisigaba sobunjineli kwaye umbono kukuba le iphenyo yokucinga inakho yiya kwinkqubo yeDidymos, Yenziwe nguDidymain, into emalunga ne-780 yeemitha ububanzi apho i-Didymoon ijikeleza khona, luhlobo lwenyanga emalunga ne-160 yeemitha ububanzi.
Njengoko ubona, sithetha ngezinto ezimbini ezinkulu kakhulu, ukukunika umbono, Ngaba i-Didymain inokuba nobukhulu bentaba ngelixa inyanga yayo, iDidymoon inkulu, iphantse yafana nepiramidi yaseGiza, izinto ezinobungakanani obugqibeleleyo njenge Ukusebenza njengenjongo yokuphanda i-asteroids kwaye nokwenza uthotho lweemvavanyo kwanokuzama ukhuseleko lweplanethi. Elinye inqaku lokugcina engqondweni kukuba, ukuza kuthi ga ngoku, Iinkqubo zokubini azizange ziphononongwe ngaphambili Ke, njengoko abaphandi beqinisekisile, zininzi izinto ezimangazayo ezilindelekileyo.
Ingenza njani enye into, ikakhulu ngenxa yenani elikhulu lemiceli mngeni ekufuneka lijongane neqela leenjineli kunye nabaphandi abaphuhlisa le mishini, bagqibe ekubeni bafake indawo enkulu yeqela ngelo xesha, ebethatha inxaxheba kwimisebenzi yeRosetta. Amava ayimfuneko kuba kufuneka bajongane nemiceli mngeni eyahlukeneyo enxulumene, umzekelo, ne isikhokelo kunye neenkqubo zokuhamba Nokuba une imeko yendalo ephantsi kakhulu.
UHera uza kuqala indlela yakhe emva nje kwenjongo ye-NASA ye-DART
Njengoko kutyhilwe yi-ESA uqobo, injongo yayo yonke le njongo iya kuba, emva kokuqonda ukuba ezi ntlobo zezinto zisebenza njani emajukujukwini, ukuphuhlisa iimephu zokwazi umphezulu nokwakheka kweDidmoon, enye yezona zinto zibalulekileyo ze-asteroids. ziye zafunyanwa ukuza kuthi ga ngoku. Ukwenza lo msebenzi, intsebenziswano yeNASA, injongo yayo Uvavanyo oluphindwe kabini lwe-Asteroid Redirection (DART) luya kuba sisitshixo.
Iinjongo eziza kwenziwa yi-NASA ziya kuba yinto ephambili kuba, ngokutsho kwengqikelelo ye-arhente, kwi-2022 enye yeenkqubo zayo iya kuba nefuthe ne-Didymoon zama ukuphambukisa le nyanga kwi-orbit yayo yangoku ejikeleze i-Didymain. Eli nyathelo liya kuba lelokuqala ngohlobo lwalo ukwenziwa ngabantu kwaye kulapho uHera aya kuthi akwazi ukusinika khona ulwazi olubalulekileyo malunga notshintsho olwenzekileyo kwinkqubo yokubini.
Njengoko kuphawuliwe UIan CarnelliUmphathi wemishini kaHera kwingxelo:
Inkqubo ye-Didymos yeyona bhedi yovavanyo ilungileyo yovavanyo lokhuselo lweplanethi, kodwa ikwayindawo entsha ngokupheleleyo yophando lwe-asteroid. Nangona ii-binaries zenza i-15% yazo zonke ii-asteroids ezaziwayo, azikaze zihlolwe ngaphambili, kwaye silindele uninzi lwezimanga.
Uphando lukaHera luza kusinika ubunzima be-Didymoon, ukumila komngxuma, kunye neempawu zedidimoyo ebonakalayo kunye namandla. Lonke ulwazi oluqokelelwe emva kwempembelelo ye-DART kunye nesifundo sikaHera sinokuba sisixhobo sokukhusela iplanethi kwaye sinokuphinda sibuye xa sinokufuna ukumisa i-asteroid engenayo.
