Rattadeta v\u00f5i mootorita auto on v\u00e4hev\u00e4\u00e4rtuslik. Samamoodi on ka satelliidil teatud osad, mis peavad olema sisse ehitatud.<\/p>\n<\/div>\n

Enamik kosmoselaevu saab oma toite akudest ja p\u00e4ikesepatareidest. P\u00e4ikesepatareid on kiibitaolised r\u00e4ni- v\u00f5i muudest materjalidest t\u00fckid, mis toodavad elektrit, kui p\u00e4ikesevalgus neile langeb.<\/p>\n

Kui tuhandeid selliseid rakke \u00fchendatakse suurtesse paneelidesse, moodustades p\u00e4ikesepaneelid, suudavad need varustada energiaga m\u00e4rkimisv\u00e4\u00e4rse suurusega kosmoselaeva. Rakud laadivad akusid ka siis, kui need on p\u00e4ikesevalguses. Kui kosmoselaev satub varju, v\u00f5tavad akud toiteallika \u00fcle.<\/p>\n

Kosmoselaevadel on mitu antenni. Need toimivad nagu k\u00f5rvad ja tagavad side\u00fchenduse Maaga. Neist k\u00f5ige olulisem on kuni 2 m l\u00e4bim\u00f5\u00f5duga paraboolantenn, mis suudab saata ja vastu v\u00f5tta suuri andme- ja infokoguseid.<\/p>\n

Kosmoselaeva aju on selle arvutis\u00fcsteem. Andmeid saab salvestada arvuti m\u00e4llu v\u00f5i saata antennide kaudu reaalajas Maale.<\/p>\n

Arvuti salvestab ka juhised kosmoselaeva juhtimiseks. See tagab varuv\u00f5imaluse juhuks, kui side katkeb v\u00f5i tekib rike.<\/p>\n

Kosmoselaevad vajavad kosmoses liikumiseks ka v\u00e4ikeseid mootoreid. Mootoreid on erinevaid t\u00fc\u00fcpe.<\/p>\n

Kosmoselaevad p\u00f6\u00f6ravad ja veerevad, k\u00e4ivitades t\u00f5ukurid. Need paiskavad kuuma gaasi suure kiirusega kosmosesse. M\u00f5ned satelliidid on varustatud ioonmootoritega. Need kasutavad tugevat elektriv\u00e4lja, et gaasi kosmosesse paisata.<\/p>","protected":false},"excerpt":{"rendered":"
