Avtomobil brez koles ali motorja nima velike vrednosti. Enako velja tudi za satelit, v katerega morajo biti vgrajeni dolo\u010deni deli.<\/p>\n<\/div>\n

Ve\u010dina vesoljskih plovil za oskrbo z energijo uporablja baterije in son\u010dne celice. Son\u010dne celice so plo\u0161\u010dasti kosi silicija ali drugih materialov, ki proizvajajo elektri\u010dno energijo, ko nanje pade son\u010dna svetloba.<\/p>\n

\u010ce se tiso\u010de teh celic pove\u017ee v velike plo\u0161\u010de, ki tvorijo son\u010dne celice, lahko napajajo precej veliko vesoljsko plovilo. Celice prav tako polnijo baterije, kadar so izpostavljene son\u010dni svetlobi. Ko vesoljsko plovilo vstopi v senco, prevzamejo napajanje baterije.<\/p>\n

Vesoljska plovila so opremljena z ve\u010d antenami. Te delujejo kot u\u0161esa in omogo\u010dajo komunikacijske povezave z Zemljo. Najpomembnej\u0161a med njimi je paraboli\u010dna antena s premerom do 2 m, ki lahko po\u0161ilja in sprejema velike koli\u010dine podatkov in informacij.<\/p>\n

Mo\u017egani vesoljskega plovila so njegov ra\u010dunalni\u0161ki sistem. Podatke je mogo\u010de shraniti v ra\u010dunalni\u0161ki pomnilnik ali pa jih v realnem \u010dasu prek anten poslati nazaj na Zemljo.<\/p>\n

Ra\u010dunalnik hrani tudi navodila za upravljanje vesoljskega plovila. To slu\u017ei kot varnostna re\u0161itev za primer izgube stika ali okvare.<\/p>\n

Vesoljska plovila potrebujejo tudi majhne motorje za krmarjenje v vesolju. Obstajajo razli\u010dne vrste motorjev.<\/p>\n

Vesoljska plovila se obra\u010dajo in nagibajo z v\u017eigom pogonskih motorjev. Ti z visoko hitrostjo izstreljujejo vro\u010de pline v vesolje. Nekateri sateliti imajo ionske motorje. Ti z mo\u010dnim elektri\u010dnim poljem izstreljujejo plin v vesolje.<\/p>","protected":false},"excerpt":{"rendered":"
