Lub National Aeronautics thiab Space Administration (NASA) tab tom txiav txim siab txo tus naj npawb ntawm astronauts ntawm International Space Station los ntawm peb mus rau ib qho. Qhov kev txav no yog vim qeeb hauv kev npaj ntawm SpaceX thiab Boeing spacecraft, nrog rau txo qhov zaus ntawm kev ya davhlau ntawm Lavxias Soyuz spacecraft. Qhov no tau hais hauv tsab ntawv ceeb toom los ntawm NASA Tus Thawj Saib Xyuas Paul Martin.
"Ua ntej pib lub davhlau ya nyob twg, NASA yuav zoo li yuav tsum tau txo tus naj npawb ntawm cov neeg caij nkoj ntawm ISS los ntawm peb mus rau ib qho pib thaum lub caij nplooj ntoo hlav xyoo 2020," Mr. Martin tau hais hauv tsab ntawv ceeb toom.
Nws kuj tau sau tseg tias qhov kev txiav txim siab no tuaj yeem ua tau vim muaj teeb meem tshwm sim cuam tshuam txog kev txhim kho cov tshuab rau kev ya mus rau sab nraud los ntawm SpaceX thiab Boeing. Nws tau raug sau tseg tias cov tuam txhab engineers tam sim no tau ntsib teeb meem cuam tshuam nrog kev txhim kho cov cav, tso tawm aborts thiab parachute systems. Lwm qhov laj thawj rau kev txo qis ntawm cov neeg nyob hauv lub hnub qub tuaj yeem yog qhov txo qis ntawm kev siv Soyuz spacecraft.
Cov ntaub ntawv hais tias yog tias tsuas yog ib tus neeg caij dav hlau tseem nyob ntawm ISS, nws cov haujlwm yuav raug txwv rau kev ua haujlwm thiab kho dua tshiab. Qhov no yuav ua rau lub sijhawm tsis txaus los ua kev tshawb fawb txog kev tshawb fawb thiab ua kom pom cov thev naus laus zis ntsig txog NASA lub hom phiaj kev tshawb nrhiav chaw yav tom ntej.
Raws li cov ntaub ntawv luam tawm, dhau 20 xyoo, 85 tus neeg caij dav hlau mus rau ISS tau ua tiav siv Lavxias Soyuz spacecraft thiab American Space Shuttle. Nyob rau hauv tag nrho, 239 tus neeg los ntawm ntau lub teb chaws tuaj xyuas lub chaw nres tsheb lub sijhawm no.
