Cov txiaj ntsig tseem ceeb ntawm cov yeeb yaj kiab hloov hluav taws xob yog nyob rau hauv nws qhov kub thiab txias ua haujlwm. Nws cov kua dej ua kom zoo tuaj yeem tiv taus qhov kub thiab txias ntawm -20℃txog 120 degree, kom ntseeg tau ntev -lub sij hawm xim ceev txawm tias siv sab nraum zoov. Nws cov yam ntxwv hloov mus rau lub sijhawm ntev (ib lub voj voog cua sov tuaj yeem siv sijhawm ntev dua 30 feeb) tso cai rau kev hloov pauv tag nrho ntawm thaj chaw loj lossis cov qauv nyuaj, tsis txhob muaj cov ntawv luam tawm hauv zos.
Tsis tas li ntawd, nkhaus hloov tshuab, los ntawm kev sib xyaw ua ke ntawm lub hauv paus zaj duab xis thiab cov cwj mem hloov tau yooj yim, tuaj yeem hloov kho rau cov hlau qhov chaw nrog qhov curvature ntawm tsawg dua 180 degree, xws li cov hlab ntsha cylindrical lossis qhov tsis sib xws, daws qhov teeb meem ntawm cov teeb meem adhesion inherent hauv cov qauv luam ntawv.
