Uhlelo lokuhlola ludinga ukuthi izinjini ezine zerokhethi ze-RS-25 zidubule imizuzu engaphezudlwana kwesishiyagalombili - isikhathi esilinganayo esizothatha ukuthumela irokhethi emkhathini ngemuva kokwethulwa. Ithimba liqede ngempumelelo ukubala futhi lashisa izinjini, kepha izinjini zacisha kancane ngaphezu komzuzu owodwa emlilweni oshisayo. Amaqembu ahlola idatha ukuthola ukuthi yini ebangele ukuvalwa kwangaphambi kwesikhathi, futhi azonquma indlela eya phambili.
Okokuhlola, izinyawo ezingama-212 isigaba esiyisisekelo kukhiqizwe ama-1.6 wezigidi zamaphawundi, ngenkathi iboshelwe kwi-B-2 Test Stand eStennis Space Center yeNASA ngaseBay St. Louis, eMississippi. Ukuhlolwa komlilo okushisayo kufaka phakathi ukulayisha amakhilogremu angama-733,000 oksijini oketshezi kanye ne-hydrogen ewuketshezi - okufaka inqubo yokuqalisa ukubala phansi - nokufaka izinjini.
"Ukuhlolwa kwangoMgqibelo bekuyinyathelo elibalulekile eliya phambili ukuqinisekisa ukuthi isigaba esiyinhloko samarokhethi e-SLS sikulungele ukuthunywa kuka-Artemis I, nokuthwala iqembu emisebenzini ezayo," kusho uMphathi weNASA uJim Bridenstine, obehambele lolu vivinyo. "Yize izinjini zingazange zicishe isikhathi esigcwele, iqembu lisebenze ngempumelelo lapho kubalwa khona izimoto, lasha izinjini, lathola nemininingwane ebalulekile yokwazisa ngomkhondo wethu."
Amaqembu okusekela kuyo yonke indawo yokuhlolwa kweStennis ahlinzekele amagesi anomfutho ophakeme esitendini sokuhlola, aletha wonke amandla kagesi asebenzayo, ahlinzeka ngaphezu kwamalitha ayi-330,000 wamanzi ngomzuzu ukuvikela isivikeli ilangabi futhi aqinisekise ubuqotho besakhiwo sesiteji esiyinhloko, futhi idatha ethathiwe iyadingeka ukuhlola ukusebenza kwesiteji esiyisisekelo.
"Ukubona zonke izinjini ezine zivutha okokuqala ngesikhathi sokuhlolwa komlilo esiteji esiyisisekelo kube yingqophamlando enkulu eqenjini le-Space Launch System" kusho uJohn Honeycutt, umphathi wohlelo lwe-SLS eMarshall Space Flight Centre yeNASA eHuntsville, e-Alabama. "Sizohlaziya imininingwane, futhi lokho esikufunde esivivinyweni sanamuhla kuzosisiza ukuthi sihlele indlela efanelekile yokuqinisekisa ukuthi lesi sigaba esisha esisha sikulungele ukubaleka emkhankasweni ka-Artemis I."
The I-Green Run uchungechunge lwezivivinyo lwaqala ngoJanuwari 2020, lapho inkundla yethulwa eMichoud Assembly Facility yeNASA eNew Orleans futhi yafakwa endaweni yokuhlola i-B-2 eStennis. Iqembu liqede ukuhlolwa kokuqala kokuyisishiyagalombili ochungechungeni lweGreen Run ngaphambi kokuma phansi ngoMashi ngenxa yesifo esiqhubekayo se-coronavirus. Ngemuva kokuqalisa kabusha umsebenzi ngoMeyi, iqembu lasebenza ngokuhlolwa okusele ochungechungeni, ngenkathi libuye lime ngezikhathi ezithile njengoba iziphepho eziyisithupha ezishisayo noma iziphepho zithinta iGulf Coast. Ukuhlolwa ngakunye okwakhelwe esivivinyweni sangaphambilini ngobunzima obukhulayo bokuhlola amasistimu asezingeni eliphakeme, kanti isivivinyo somlilo oshisayo okhanyise zonke izinjini ezine kwaba isivivinyo sokugcina uchungechunge.
"UStennis akakaze alibone leli zinga lamandla selokhu kwahlolwa izigaba zeSaturn V ngawo-1960," kusho uMqondisi weStennis Centre uRick Gilbrech. “IStennis yisona sikhundla sokuqala sokukhishwa kwamarokhethi esivivinye iSaturn V isigaba sokuqala nesesibili esasihambisa abantu eNyangeni ngesikhathi sohlelo lwe-Apollo, manje, lo mlilo oshisayo yingakho nje sihlola sengathi siyandiza futhi sindiza njengoba sihlola. Sizofunda kusukela ekuvalweni kwanamuhla kwanamuhla, sikhombe noma yikuphi ukulungiswa lapho kudingeka khona, siphokophele phambili. ”
Ngaphezu kokuhlaziya imininingwane, amaqembu nawo azobheka isigaba sokuqala kanye nezinjini zayo ezine ze-RS-25 ngaphambi kokunquma izinyathelo ezilandelayo. Ngaphansi kwe- u-Arthemisi Uhlelo, i-NASA isebenza ukuthola owesifazane wokuqala kanye nowesilisa olandelayo eNyangeni ngo-2024. I-SLS kanye nomkhumbi-mkhathi we-Orion ozothwala osomkhathi baye emkhathini, kanye nohlelo lokufika kwabantu kanye neGateway ekuzungezeni iNyanga, kungumgogodla weNASA yokuhlola indawo ejulile ..
