Lesi akusona okokuqala sikhuluma ngesibonakude sasemkhathini i-Kepler, esafakwa emzileni ngaleso sikhathi ngenhloso eqinile thola amaplanethi afana noMhlaba azungeza izinkanyezi ezifana neLanga lethu. Ngenxa yalokhu, kwakwakhiwa ipulatifomu eyayikwazi ukubuka ngasikhathi sinye izinkanyezi ezingekho ngaphansi kwe-150.000 ngenkathi ihlaziya ukukhanya kwayo njalo ngemizuzu engama-30 ukuze kutholakale ukuhamba kwamaplanethi.
Ngokuningiliziwe, ngemuva kokwakhiwa nokwakhiwa kwesibonakude sasemkhathini, esathola ukubambezeleka okuningana nokuvela, ekugcineni yethulwa ku-orbit ngoMashi 2009. Ekuqaleni, imishini yayinesikhathi esilindelekile seminyaka eyi-3 nengxenye, efanayo naleyo bekufanele iphele ngasekupheleni kuka-2012 nokuthi, ngenxa yokusebenza kahle kwayo futhi ikakhulukazi ukungabikho kwemali, yandiswa kwaze kwaba ngu-2016.
Iqiniso ukuthi phakathi naso sonke lesi sikhathi impilo kaKepler ibingelula neze selokhu, ngandlela thile kuvele izinkinga ezahlukahlukene lokho ekugcineni kulungisiwe. Isibonelo salokhu engikushoyo ukuthi ngo-2013 ulahlekelwe ngamawheelwheel amabili kwamane amsizile wamzinzisa waphinde walungisa indlela eya kuma-lens akhe. Le kwakuyinkinga eyayiqala Umsebenzi we-K2, okuholele ekutholeni ama-exoplanet angu-2.245 2.342 kanye namanye ama-XNUMX okusamele kuqinisekiswe.
Ngemuva kweminyaka ecishe ibe yishumi emkhathini, ezinyangeni ezimbalwa uKepler ekugcineni uzocisha
Yize kube nempumelelo enkulu esesiyizuzile lesi sibonakude sasemkhathini eminyakeni ecishe ibe yishumi yokusebenza ngokungakhathali nangemuva kokunqoba izinkinga ezimbalwa ezinkulu, uma kungenzeka kunikeza impumelelo enkulu kumishini, iqiniso ukuthi uKepler ubhekene nenye engenakuxazululwa nokuthi, ngenxa yalokho, kuzophela ukuthunywa kwakhe. Inkinga engaxazululwa ayikho enye ngaphandle kweqiniso elilula lokuthi isibonakude siyaphela uphethiloli.
Ukuzibeka esimweni kancane, ngikutshele lokho njengamanje UKepler use-orbit cishe amakhilomitha ayizigidi eziyi-150 ukusuka eMhlabeni, okuthile okwenza kube nzima ukuthumela umkhumbi ngophethiloli ukulayisha amathangi awo. Ngokusobala futhi njengoba kubikiwe yi-NASA, uKepler kulindeleke ukuthi ayeke ukusebenza ezinyangeni ezimbalwa nje yize bebuye baphawule ukuthi bafunda zonke izindlela isibonakude sasemkhathini ezingakhuphula ngazo isikhathi saso sokusebenza, into esivele ikwazile ukuyenza izikhathi eziningana.
Njengoba kungenzeka ucabanga, namuhla onjiniyela beNASA bazama ngazo zonke izindlela lokho I-Kepler Space Telescope isebenza ukuqoqa yonke idatha engayithola iphinde iyithumele eMhlabeni ngaphambi kokugcina ukulahleka kwe-propellants esebenza ngenxa yokushiswa kukaphethiloli, lapho ngeke sikwazi ukuxhumana nesibonakude sasemkhathini.
Isikhathi esisele noKepler asinakubikezelwa ngenxa yokushoda kwegeji kaphethiloli
Enye yezinkinga ezinkulu onjiniyela ababhekana nazo ukulungisa iqiniso lokuthi uKepler uzogcina evaliwe, kwesinye isikhathi noma kwesinye, ukuthi empeleni abazi ukuthi basalelwe isikhathi esingakanani. Lokhu kunjalo ngoba kuyefana ayinayo imitha yegesi. Esinye sezixazululo eziphakanyisiwe ukuthi, ukwazi inani likaphethiloli, abacwaningi bazoncika ekulahlekelweni kokusebenza kwezihambisi noma ingcindezi ithangi likaphethiloli uqobo olunayo.
Ukuqonda okwakamuva kangcono kangcono ngizokutshela isibonelo iNASA uqobo eyinikeze lapho beqhathanise khona le nkinga nemoto. Emotweni, uma uphethwe uphethiloli omncane, unezinto ezimbili ongakhetha kuzo, gembula bese ulinda ukudlula esiteshini esilandelayo ukufaka uphethiloli, ngale ndlela uKepler ngeke athole lutho olungasebenzisa uphethiloli emgwaqeni, ngakho-ke kuphela ukuze sizame ukumyisa kude ngangokunokwenzeka emsebenzini wakhe, okungukuthi, lokho qoqa yonke idatha ongaqinisekisa ukuthi ingathunyelwa eMhlabeni.
