Kuyiqiniso ukuthi kungekudala i-NASA yakhulume esidlangalaleni kuHulumeni wase-United States uhlobo lwecebo lokuthi abaseMelika, kubandakanya bonke abantu abasemhlabeni, kumele babambisane ekuqalisweni kwalo okuqhubekayo ukuze kuzuzwe, ngendlela okungenzeka ngayo, baphile iplanethi ngaphambi a ngaphezulu kokushayisana kwe-asteroid enkulu emelene noMhlaba uqobo.
Manje yisikhathi sokukhuluma ngomsebenzi weHera lapho ososayensi nabaphenyi be-ESA, i-European Space Agency, basebenza khona. Ngokwami, kufanele ngivume ukuthi inhloso yeHera ihlose, njengasendabeni yemephu yesenzo ehlelwe yiNASA, ukubeka isixazululo sokuthi i-asteroid noma olunye uhlobo lwento enkulu lushaya uMhlaba, kulokhu iqiniso ukuthi kwa-ESA baqhubeka kancane ngoba, phakathi kwezinhlelo zabo, ukutadisha enye yalezi zinto futhi thola indlela engcono yokuyiphambukisa kusuka emzileni wayo.
I-ESA isivele isebenza ekuthuthukiseni umsebenzi weHera
Ukungena emininingwaneni ethe xaxa, lokho i-ESA esebenza ngakho uhlelo olunenhloso enkulu yokuthumela uhlobo oluthile lwe-probe ohlelweni lwe-asteroid kanambambili ngo-2026. Okwamanje inhloso isivele isesigabeni sonjiniyela futhi umqondo ukuthi lokhu iphenyo yokuqagela ingakwazi hamba uye ohlelweni lwe-Didymos, eyakhiwe nguDidymain, into engamamitha angaba ngu-780 ububanzi lapho i-Didymoon izungeza khona, uhlobo lwenyanga olungamamitha angaba ngu-160 ububanzi.
Njengoba ukwazi ukubona, sikhuluma ngezinto ezimbili ezinkulu kakhulu, ukukunika umbono, iDidymain ibizoba nosayizi wentaba ngenkathi inyanga yayo, iDidymoon inkulu, icishe ifane nepiramidi yaseGiza, izinto ezinosayizi ophelele njenge ukusebenza njengenhloso yokuphenya ama-asteroid futhi nokwenza uchungechunge lwezivivinyo kanye nokuhlolwa kokuvikela iplanethi. Elinye iphuzu okufanele ulikhumbule ukuthi, kuze kube manje, izinhlelo kanambambili azikaze zihlolwe ngaphambili Ngakho-ke, njengoba abacwaningi beqinisekisile, kulindelwe izimanga eziningi.
Kungaba kanjani ngenye indlela, ikakhulukazi ngenxa yenqwaba yezinselelo iqembu lonjiniyela nabaphenyi abathuthukisa le mishini okufanele babhekane nazo, banqume ukufaka ingxenye enkulu yeqembu okwathi ngaleso sikhathi, wabamba iqhaza eRosetta ukusebenza, isipiliyoni esibalulekile ngoba kumele babhekane nezinselelo ezahlukahlukene ezihlobene, ngokwesibonelo, nge izinkomba zokuqondisa nokuzula noma ngabe nge imvelo yamandla adonsela phansi kakhulu.
UHera uzoqala indlela yakhe ngemuva nje komsebenzi weNASA we-DART
Njengoba kuvezwe yi-ESA uqobo lwayo, inhloso yalo msebenzi wonke, kungaba, ngemuva kokuqonda ukuthi lezi zinhlobo zezinto zisebenza kanjani esikhaleni, ukwenza amabalazwe okwazi ubuso nokwakheka kwe-Didymoon, enye yama-asteroid abaluleke kakhulu. zitholakele kuze kube manje. Ukuze kwenziwe lo msebenzi, kuzodingeka ukusebenzisana kweNASA, okuyinjongo yayo Ukuhlolwa kwe-Double Asteroid Redirection (DART) kuzoba ukhiye.
Umsebenzi ozoqhutshwa yiNASA uzoba ngukhiye ngoba, ngokusho kwesibikezelo salesi sikhungo, ngo-2022 esinye sezinkinga zaso sizothinta iDidmoon zama ukuphambukisa le nyanga emzileni wayo wamanje ozungeze i-Didymain. Lesi senzo sizoba ngesokuqala ngohlobo lwaso ukwenziwa ngabantu futhi ilapho kanye uHera azokwazi ukusinikeza imininingwane ebalulekile mayelana nezinguquko ezenzeke ohlelweni lwe-kanambambili.
Njengoba kuphawuliwe U-Ian Carnelli, Umphathi wemishini kaHera esitatimendeni:
Uhlelo lwe-Didymos ngumbhede wokuhlola ophelele wokuhlolwa kokuvikela kwamaplanethi, kodwa futhi kuyindawo entsha ngokuphelele yophenyo lwe-asteroid. Yize ama-binaries enza i-15% yawo wonke ama-asteroid aziwayo, awakaze ahlolwe phambilini, futhi silindele izimanga eziningi.
Ucwaningo lukaHera luzosinika isisindo seDidmoon, ukwakheka komgodi, kanye nezakhiwo zeDidmoon ezibonakalayo nezingamandla. Yonke imininingwane eqoqwe ngemuva komthelela we-DART kanye nokutadisha kukaHera kungaba yindlela yokuvikela amaplanethi futhi iphindaphindwe uma kwenzeka sidinga ukumisa i-asteroid engenayo.
