O ma\u0219in\u0103 f\u0103r\u0103 ro\u021bi sau f\u0103r\u0103 motor nu valoreaz\u0103 prea mult. La fel, exist\u0103 anumite componente care trebuie integrate \u00eentr-un satelit.<\/p>\n<\/div>\n

Majoritatea navelor spa\u021biale se alimenteaz\u0103 cu energie electric\u0103 provenit\u0103 din baterii \u0219i celule solare. Celulele solare sunt pl\u0103cu\u021be din siliciu sau din alte materiale care produc energie electric\u0103 atunci c\u00e2nd sunt expuse la lumina soarelui.<\/p>\n

Dac\u0103 mii dintre aceste celule sunt conectate \u00een panouri mari pentru a forma panouri solare, ele pot alimenta cu energie o nav\u0103 spa\u021bial\u0103 de dimensiuni considerabile. De asemenea, celulele \u00eencarc\u0103 bateriile ori de c\u00e2te ori sunt expuse la lumina soarelui. C\u00e2nd o nav\u0103 spa\u021bial\u0103 intr\u0103 \u00een umbr\u0103, bateriile preiau alimentarea.<\/p>\n

Navele spa\u021biale sunt echipate cu mai multe antene. Acestea func\u021bioneaz\u0103 ca ni\u0219te urechi \u0219i asigur\u0103 leg\u0103turile de comunica\u021bie cu P\u0103m\u00e2ntul. Cea mai important\u0103 dintre acestea este o anten\u0103 parabolic\u0103 cu diametrul de p\u00e2n\u0103 la 2 m, care poate transmite \u0219i recep\u021biona cantit\u0103\u021bi mari de date \u0219i informa\u021bii.<\/p>\n

Creierul navei spa\u021biale este sistemul s\u0103u informatic. Datele pot fi stocate \u00een memoria computerului sau transmise \u00eenapoi pe P\u0103m\u00e2nt \u00een timp real prin intermediul antenelor.<\/p>\n

De asemenea, computerul stocheaz\u0103 instruc\u021biuni privind modul de func\u021bionare a navei spa\u021biale. Acest lucru asigur\u0103 o solu\u021bie de rezerv\u0103 \u00een cazul \u00een care se pierde leg\u0103tura sau apare o defec\u021biune.<\/p>\n

Navele spa\u021biale au nevoie, de asemenea, de motoare mici pentru a se deplasa \u00een spa\u021biu. Exist\u0103 diferite tipuri de motoare.<\/p>\n

Navele spa\u021biale se rotesc \u0219i se r\u0103sucesc prin ac\u021bionarea propulsoarelor. Acestea expulzeaz\u0103 gaze fierbin\u021bi \u00een spa\u021biu cu vitez\u0103 mare. Unii sateli\u021bi sunt echipa\u021bi cu motoare ionice. Acestea utilizeaz\u0103 un c\u00e2mp electric puternic pentru a propulsa gazul \u00een spa\u021biu.<\/p>","protected":false},"excerpt":{"rendered":"
