\u00cen martie 2002, panourile solare ale Telescopului Spa\u021bial Hubble au fost aduse \u00eenapoi pe P\u0103m\u00e2nt. Dup\u0103 opt ani petrecu\u021bi \u00een spa\u021biu, panourile furnizate de ESA erau acoperite de cratere de impact cu diametrul de p\u00e2n\u0103 la 8 mm.<\/p>\n<\/div>\n

Craterele au fost create de fragmente de de\u0219euri spa\u021biale care se deplasau cu vitez\u0103 mare. Deplas\u00e2ndu-se mai repede dec\u00e2t un glon\u021b, chiar \u0219i o buc\u0103\u021bic\u0103 de vopsea poate provoca daune grave unei nave spa\u021biale. La sf\u00e2r\u0219itul anului 2003, erau monitorizate aproximativ 10 000 de fragmente de de\u0219euri. Printre acestea se num\u0103rau nave spa\u021biale scoase din uz, trepte vechi de rachet\u0103 \u0219i c\u00e2teva unelte pierdute \u00een timpul ie\u0219irilor \u00een spa\u021biu.<\/p>\n

Multe alte obiecte sunt prea mici pentru a putea fi \u00eenregistrate. S-ar putea s\u0103 existe jum\u0103tate de milion de obiecte cu diametrul cuprins \u00eentre 1 \u0219i 10 cm \u2013 dar nimeni nu cunoa\u0219te cifra exact\u0103. ESA abordeaz\u0103 problema de\u0219eurilor spa\u021biale \u00een diverse moduri. Laboratorul Columbus de pe Sta\u021bia Spa\u021bial\u0103 Interna\u021bional\u0103 va fi protejat printr-un scut special.<\/p>\n

Cercet\u0103torii ESA din Germania \u0219i Olanda \u021bin un catalog al tuturor obiectelor cunoscute care se afl\u0103 pe orbita P\u0103m\u00e2ntului. Ei folosesc aceste date pentru a studia de\u0219eurile spa\u021biale \u0219i pentru a emite avertismente \u00een avans cu privire la posibile coliziuni.<\/p>\n

Informa\u021biile privind de\u0219eurile orbitale sunt furnizate de un scaner radar din Germania \u0219i de un telescop al ESA din Tenerife, Spania. De asemenea, ESA urm\u0103re\u0219te \u00eencheierea unor acorduri interna\u021bionale pentru reducerea de\u0219eurilor spa\u021biale \u0219i sporirea siguran\u021bei zborurilor spa\u021biale.<\/p>","protected":false},"excerpt":{"rendered":"
