Kujutage ette, kuidas k\u00f5ndida kosmoses ja lennata \u00fcmber Maa kiirusega \u00fcle 27 000 km\/h! Just seda on viimase 50 aasta jooksul kogenud sadu kosmosek\u00f5ndijaid. Kosmosek\u00f5nnid (ametlik nimetus \u201eExtravehicular Activity\u201c ehk EVA) on kosmoset\u00f6\u00f6 oluline osa. Neid kasutatakse uute seadmete ja eksperimentide paigaldamiseks ning remondit\u00f6\u00f6de tegemiseks. Rahvusvahelise kosmosejaama ehitamiseks ja hooldamiseks on alates 1998. aastast vaja olnud ligi 1 000 tundi kosmosek\u00f5nne.<\/p>\n<\/div>\n

Kosmosek\u00f5ndijad kannavad kaitseriietust, kui nad sisenevad \u00f5huta vaakumisse. Need riided koosnevad paljudest erinevatest kihtidest, mis hoiavad kandja kehatemperatuuri \u00f5igel tasemel, v\u00f5imaldavad tal hingata ja kaitsevad teda kahjuliku kiirguse eest. Hapniku r\u00f5hk \u00fclikondade sees on madalam kui kosmosjaamas. Seet\u00f5ttu peavad astronaudid veetma umbes neli tundi hapnikku hingates \u00f5hulukus, enne kui nad saavad v\u00e4ljapoole astuda.<\/p>\n

ISS-il hoitakse kahte erinevat survekost\u00fc\u00fcmi. Ameerika kost\u00fc\u00fcm koosneb kahest osast: k\u00f5vast \u00fclakehast ja paindlikust alakehast. Need osad \u00fchenduvad v\u00f6\u00f6kohas. Astronaudi jalad surutakse p\u00fckstesse, seej\u00e4rel paigutatakse k\u00e4ed ja \u00fclakeha \u00fclemisse osasse. Vene skafandril on j\u00e4ik \u00fclemine osa, millel on tagaluuk, kus asub ka elutagamiss\u00fcsteem. See muudab \u00fche k\u00e4ega selga panemise lihtsamaks. M\u00f5lemal skafandril on eraldi kindad ja kiivrid.<\/p>\n

Kosmosek\u00f5ndijaid veetakse sageli \u00fchest kohast teise robotk\u00e4e otsas. Liikumiseks on olemas ka spetsiaalsed k\u00e4sipuud. Et nad ei ujuks \u00e4ra ega kaoks kosmosesse, on nad jaamaga \u00fchendatud \u00f5hukeste n\u00f6\u00f6ridega. Kosmosek\u00f5nnid v\u00f5ivad kesta mitu tundi. Rekordi hoiavad Susan Helms ja James Voss, kes veetsid 2001. aasta m\u00e4rtsis kosmoses peaaegu 9 tundi.<\/p>","protected":false},"excerpt":{"rendered":"
