I-NASA ifinyelele ingqophamlando ngokwethulwa kwe-Nancy Grace Roman Space Telescope, eyasuka ngo-13:26 ntambama ngesikhathi saseSpain isuka eKennedy Space Center eFlorida. Irokhethi i-Falcon Heavy ye-SpaceX yathwala indawo yokubuka, ebhekwa njengeyona ndawo ebanzi kakhulu eyake yakhiwa, yaya emzileni. Ukwethulwa kwaqhubeka ngaphandle kwengozi , futhi isigaba sokuqala serokhethi sabuyela eMhlabeni ukuze sifike silawulwa.
Le telesikopu, eqanjwe ngenhloko yokuqala ye-NASA yezinkanyezi, uNancy Grace Roman, inomsebenzi wayo oyinhloko wokwembula izimfihlo zamandla amnyama nezinto ezimnyama, kanye nokufuna amaplanethi angaphandle. Insimu yayo yokubuka inkulu ngokuphindwe kayikhulu kuneyeHubble Space Telescope , ezoyivumela ukuthi ikwazi ukumaka izigidigidi zemithala eminyakeni ezayo.
Ukwethulwa okungenaphutha
Ukwethulwa bekungaphambi kwezinyanga eziyisishiyagalolunye, okungajwayelekile emisebenzini yalolu bunzima. Ngemva kokuba izigaba zihlukene, ithelesikopu yaqala uhambo lwayo eya endaweni ye-L2 Lagrange, eqhele ngamakhilomitha ayizigidi ezingu-1,5 ukusuka eMhlabeni. Lapho, izokwabelana ngomjikelezo ne-James Webb Space Telescope kanye nezinye izindawo zokuhlola izinkanyezi, endaweni ezinzile ngamandla adonsela phansi evumela ukubuka okuqhubekayo.
I-NASA iqinisekisile ukuthi isigaba sesibili serokhethi sihlukane ngempumelelo nokuthi amaphaneli elanga asetshenziswa ngaphandle kwengozi. Ithelesikopu izothatha cishe izinsuku eziyi-100 ukufika lapho iya khona , lapho izoqala khona isigaba sayo sokulinganisa kanye nokuqalisa ukusebenza.
izinjongo zesayensi
Enye yezinselele ezinkulu zikaRoman ukufunda amandla amnyama, ingxenye eyimfihlakalo esheshisa ukwanda kwendawo yonke. Ithelesikopu izokala ukukhanya okuvela emithalazweni engaphezu kwezigidigidi futhi ibone i-Type Ia supernovae ukuze yakhe kabusha umlando wokwanda kwendawo yonke. Izophinde ihlaziye ukuthi udaba olumnyama lugoba kanjani ukukhanya okuvela emithalazweni ekude, into eyaziwa ngokuthi i-gravitational lensing.
Emkhakheni wama-exoplanets, uRoman uzosebenzisa i-microlensing edonsela phansi ukuthola imihlaba ezinye izindlela ezingenakuyibona, njengeplanethi eziyingozi noma ezibandayo. Kulindeleke ukuthi athole ama-exoplanets amasha afinyelela ku-100.000 , okuzokwandisa ikhathalogi yamanje ngokuphindwe kangamashumi amane, kudlule inani lama-exoplanets aqinisekisiwe kuze kube manje. Ngaphezu kwalokho, i-coronagraph yakhe yokuhlola izovumela ukuthwebula izithombe eziqondile zamaplanethi amakhulu namadiski othuli.
Ukusika ubuchwepheshe obunqenqemeni
I-observatory inezinsimbi ezimbili eziyinhloko: i-Wide Field Instrument (WFI), ikhamera engama-megapixel angu-300 enensimu yokubuka enkulu ngokuphindwe kayi-100 kune-Hubble's, kanye ne-Coronagraph Instrument (CGI), uhlelo oluthuthukisiwe lwe-optics oluvimba ukukhanya kwezinkanyezi ukuze kwembulwe izinto ezibuthakathaka. I-WFI izokhiqiza ama-terabyte angu-1,4 edatha ngosuku , okulingana nokulanda ama-movie angu-350 e-4K njalo emahoreni angu-24.
Ngenxa yamakhono ayo amakhulu okulandelela, iRoman izokwazi ukumaka iMilky Way ngenyanga eyodwa, into ezothatha iHubble ikhulu leminyaka. Izithombe zayo zizoba zikhulu kangangokuthi kuzodingeka izikrini ezingaphezu kwesigamu sesigidi ze-4K ukuze kuboniswe eyodwa kuphela , ngokusho kochwepheshe be-NASA.
Ukubambisana kwamazwe ngamazwe
URoman ngeke asebenze yedwa. Uzobambisana neJames Webb Space Telescope kanye nomsebenzi we-European Euclid ukuze anikeze umbono ophelele wendawo yonke. Ngenkathi uWebb efunda izinto ngazinye ngemininingwane eminingi, uRoman uzonikeza umongo we-panoramic, kanti u-Euclid, onensimu yakhe yombono ebanzi nakakhulu, uzozuza kudatha kaRoman esezingeni eliphezulu ukuze athuthukise izilinganiso zakhe.
Ngaphezu kwalokho, idatha kaRoman izokwabelwana ngayo esidlangalaleni ngaphandle kwesikhathi sokulinda, okuvumela izazi zezinkanyezi emhlabeni wonke ukuthi ziyifinyelele. Amagama angaphezu kwezigidi ezingu-1,3 ahamba ngetheleskopu ephepheni lesikhumbuzo, elifanekisela ukubamba iqhaza kwezakhamuzi kulo msebenzi wesayensi.
Njengoba inesabelomali esicishe sibe yizigidigidi ezine zamaRandi, i-Nancy Grace Roman Telescope ithembisa ukushintsha ukuqonda kwethu indawo yonke. Amandla ayo okubuka izindawo ezinkulu zesibhakabhaka ngokucacile okukhulu azovula iminyango emisha yocwaningo lwezinkanyezi. Izithombe zokuqala zesayensi kulindeleke ekuqaleni kuka-2027 , futhi izazi zezinkanyezi sezivele zikulindele ngabomvu ukutholwa okuzayo.
