Ua ntej, nws qhov tseem ceeb tshaj plaws yog kev txhim kho kev txav mus los thiab hloov tau yooj yim dua. Astronauts muaj kev qis qis qis zog thaum taug kev los ntawm Chaw Nres Nkoj Thoob Ntiaj Teb, tab sis ntau dua thaum taug kev ntawm lub hli thiab ua cov haujlwm tshawb fawb. Tus tshiab spacesuit tsim tag nrho xav txog qhov kev xav tau no, suav nrog ntau qhov sib koom ua ke hauv lub cev qis ntawm nws lub siab kom tso cai rau lub duav flexion thiab kev sib hloov, ntau dua lub hauv caug flexion, thiab ib qho yooj yim ib yam li cov khau boots.

Tuam Tshoj qhov chaw nres tsheb qhov chaw ua haujlwm extravehicular (EVA) suits tau ua tiav 19 EVA missions; thawj pawg ntawm EVA suits nyob rau hauv orbit tau ua kom pom kev ruaj khov thiab kev pab lub neej ntev.

 

Qhov thib ob, qhov tshiab spacesuit ho txhim kho kev nyab xeeb thiab kev tiv thaiv. Kev nyab xeeb ib txwm yog qhov tseem ceeb tshaj plaws hauv tib neeg txoj haujlwm ua haujlwm. Cov khaub ncaws EVA tshiab no tuaj yeem tiv thaiv cov neeg taug kev los ntawm hluav taws xob, plua plav plua plav, thiab micrometeoroids hauv qhov kub li ntawm -157℃txog li 121 degree.

 

Thib peb, qhov tshiab spacesuit siv tus qauv tsim qauv, ua kom yooj yim hloov cov khoom siv thaum lub sijhawm ntev - lub sijhawm tshawb nrhiav haujlwm. Piv txwv li, nws lub kaus mom hlau muaj qhov nrawm - hloov visor. Yog tias muaj kev puas tsuaj saum npoo, dents, lossis khawb, lub visor tuaj yeem hloov tau tus kheej, tshem tawm qhov xav tau xa tag nrho lub kaus mom hlau rov qab rau lub ntiaj teb los kho.

Qhov thib ob - tiam spacesuit muab kev ua haujlwm zoo dua qub thiab kev nplij siab piv rau thawj tiam. Ua tsaug rau peb lub teb chaws!

 

Plaub, qhov tshiab spacesuit txhim khu kev nplij siab. Ntawm NASA's Johnson Space Center, cov kws tshawb fawb tau ua tiav - lub cev 3D scans ntawm cov neeg nyob hauv kev txav mus los thiab tsim cov khoom raws li cov qauv 3D, ua kom muaj kev nplij siab ntawm lub spacesuit thiab txo cov tawv nqaij tsis xis nyob.
