Okonyukayo kufuneka kwehle-kwaye kuya njalo koosomajukujuku be-NASA uBob Behnken kunye noDoug Hurley, ngoku abakwi-250 yeekhilomitha ngaphezulu komphezulu woMhlaba, ojikeleza iplanethi kwi-International Space Station (ISS). I-duo imiselwe ukuba ibuyele ekhaya kule mpelaveki, ukumakisha okokuqala oosomajukujuku baya kwenza uhambo kwisiphekepheke esakhiwe ngasese - kule meko, Space caps's Crew Dragon capsule. Nantsi indlela onokubukela ngayo lo msitho kule mpelaveki.
I-rocket ye-SpaceX Falcon 9 ephethe i-Crew Dragon spacecraft yenkampani iphehlelelwa ukusuka kwi-Launch Complex 39A kwi-NASAs SpaceX Demo-2 mission kwi-International Space Station kunye noosomajukujuku be-NASA uRobert Behnken noDouglas Hurley ebhodini, ngoMgqibelo, ngoMeyi 30, 2020, kwi-NASAs Kennedy Space.

Yintoni injongo yeDemo-2 malunga nayo?
Umsebenzi weDemo-2 yintsebenziswano phakathi kwe-NASA kunye ne-SpaceX ye-Elon Musk, ephawula uvavanyo lokuqala lwenqwelomoya ye-SpaceX Crew Dragon capsule nabantu abakwibhodi. Abasebenzi bayo kunye noosomajukujuku uBob Behnken kunye noDoug Hurley, bobabini amagqala eenqwelomoya, baphehlelele ngempumelelo kwisiphekepheke esasiphezu kwerokethi ye-Falcon 9 ngoMeyi 30 ukusuka eKennedy Space Centre eKapa eKapa, eFlorida, babambelela kwi-ISS ngoMeyi 31. iphawuleka ngenxa yezizathu ezibini: Okokuqala, lixesha lokuqala oosomajukujuku besebenzisa isithuba kwibhodi yezithuthi zorhwebo, okuthetha ukuba iyilwe yinkampani yabucala hayi iNASA. Okwesibini, lixesha lokuqala oosomajukujuku besungula umhlaba wase-US ukusukela oko iphela inkqubo yasesiphekepheke yaphela ngo-2011. iminyango yexesha elitsha lokuhlola indawo yomntu, ukudala ithuba lokuba oosomajukujuku abaninzi bangaphehleleli nje emajukujukwini, kodwa baphinde babuyele enyangeni kwaye ekugqibeleni baye eMars.
Ndingajonga njani ukubuya?
Emva kokuchitha malunga neenyanga ezimbini ebhodini i-ISS kunye noosomajukujuku be-NASA uChris Cassidy kunye ne-Roscosmos cosmonauts u-Anatoly Ivanishin no-Ivan Vagner base-Russia, oosomajukujuku u-Behnken no-Hurley bazakubuyela eMhlabeni kule mpelaveki bazokugqibezela umsebenzi wabo. Iya kuba ngumnyhadala weholide, kwaye ungazibandakanya kunye nokusasazeka ngokusesikweni nge NASA TV , eziza kusasazwa ngaxeshanye kwiiwebhusayithi zeNASA kunye neSpaceX, amajelo e-YouTube, kunye neeprofayili zemidiya yoluntu.
Usasazo luqala nge-9: 10 kusasa nge-EDT ngoMgqibelo, nge-Agasti 1, kumsitho wokuvalelisa ngokusemthethweni kwibhodi ye-ISS. Ngo-5: 15 emva kwemini. I-EDT, ukugubungela kuya kuqala kwi-Crew Dragon's undocking kwi-ISS, eya kwenzeka nge-7: 34 pm Emva koko, oosomajukujuku uBehnken noHurley bazakuchitha iiyure ezili-19 okanye ukubuyela eMhlabeni, bejikeleza iplanethi ukuze bangene kwindawo efanelekileyo yokuphinda bangene emoyeni. Lonke uhambo lwabo luya kusasazwa ngqo eluntwini.
Ukwahlukana kuya kwenzeka kwi-Atlantic Ocean okanye kwiGulf yaseMexico kunxweme laseFlorida, kuxhomekeke kwiimeko, ngo-2: 42 ntambama I-EDT ngeCawa, nge-Agasti ka-2. Kodwa uya kufuna ukusasaza ukusasaza ubuncinci iyure okanye ezimbini ngaphambi koko ukuze ubukele inkqubo yokubuyisa enomdla: I-capsule izakuhamba nge-17,500 yeemayile ngeyure xa iye yangena emoyeni , kwaye iyakufikelela kumaqondo obushushu angama-3 500 degrees Fahrenheit. Emva koko, kuyakubakho malunga nemizuzu emithandathu ukunxibelelana ngombane ngexesha leyona ndawo inamandla yokungena kwakhona, apho iNASA's Mission Control kunye neCrew Dragon zingazukunxibelelana. Okokugqibela, i-capsule iya kuncitshiswa ziiparashute ezinkulu ngaphambi kokumisa kancinci elwandle. (Kwirekhodi, ukufika kokugqibela kwamanzi kwakungo-1976, xa i-capsule yaseRussia i-Soyuz yafika echibini, ngoko ke le nto ibaluleke kakhulu).
Emva kokuchaphazeleka, amaqela okubuyisa kwakhona aya kubuyisa oosomajukujuku kunye necapsule, enze zonke iintlobo zonyango kunye nokhuseleko endleleni. Ngo-5 emva kwemini. I-EDT, i-NASA iya kubamba inkomfa yeendaba malunga nomsebenzi.
Ke yintoni elandelayo kwi-SpaceX's Crew Dragon?
Ukuba konke kuhamba kakuhle nge-Demo-2's reentry, i-mission iya kuthathwa njengempumelelo, kwaye i-SpaceX iya kuba nakho ukuqala ngokusesikweni ukusebenza nge-NASA (khumbula, iDemo-2 ngobuchwephesha nje luvavanyo lovavanyo). Umsebenzi wokuqala wokusebenza kweCrew Dragon iya kuba yiCrew-1, ecwangciselwe ukwenziwa ngasekupheleni kukaSeptemba. Izakuphatha oosomajukujuku beNASA uMike Hopkins, uVictor Glover, kunye noShannon Walker, kunye noosomajukujuku weJAXA uSoichi Noguchi osuka eJapan, aye kwi-ISS.
