Majoritatea navelor spa\u021biale sunt plasate pe orbite \u00een jurul P\u0103m\u00e2ntului. \u00cens\u0103 acesta nu este \u00eentotdeauna locul optim pentru sateli\u021bii \u0219tiin\u021bifici care exploreaz\u0103 universul \u00eendep\u0103rtat.<\/p>\n<\/div>\n

Telescopul spa\u021bial Hubble urmeaz\u0103 o orbit\u0103 circular\u0103 la 600 km deasupra solului, cu o \u00eenclina\u021bie de 28,5 grade fa\u021b\u0103 de ecuator. Aceast\u0103 orbit\u0103 terestr\u0103 faciliteaz\u0103 repararea \u0219i \u00eentre\u021binerea observatorului. Cu toate acestea, P\u0103m\u00e2ntul \u0219i Luna blocheaz\u0103 por\u021biuni mari din cer.<\/p>\n

Succesorul telescopului Hubble, Telescopul Spa\u021bial James Webb, va func\u021biona la o distan\u021b\u0103 mult mai mare. Acesta va fi plasat pe o orbit\u0103 stabil\u0103 la a\u0219a-numitul punct Lagrange L2, la o distan\u021b\u0103 de 1,5 milioane de km, pe partea \u00eentunecat\u0103 a P\u0103m\u00e2ntului.<\/p>\n

L2 este unul dintre cele cinci puncte Lagrange ale P\u0103m\u00e2ntului. \u00cen aceste puncte, for\u021bele gravita\u021bionale ale P\u0103m\u00e2ntului, Lunii \u0219i Soarelui se anuleaz\u0103 reciproc, astfel \u00eenc\u00e2t este u\u0219or s\u0103 se men\u021bin\u0103 un satelit \u00een aceea\u0219i pozi\u021bie.<\/p>\n

Al\u021bi sateli\u021bi, precum observatorul SOHO al ESA, trebuie s\u0103 observe Soarele \u00een permanen\u021b\u0103. Aceast\u0103 nav\u0103 spa\u021bial\u0103 este pozi\u021bionat\u0103 la punctul Lagrange L1, la 1,5 milioane de km \u00een direc\u021bia Soarelui fa\u021b\u0103 de P\u0103m\u00e2nt.<\/p>\n

Deoarece for\u021bele gravita\u021bionale ale P\u0103m\u00e2ntului \u0219i ale Soarelui se echilibreaz\u0103 la punctul L1, SOHO poate r\u0103m\u00e2ne \u00een zbor sta\u021bionar \u00eentre cele dou\u0103 corpuri cere\u0219ti \u00een permanen\u021b\u0103, f\u0103r\u0103 a consuma prea mult combustibil.<\/p>","protected":false},"excerpt":{"rendered":"
