Az \u0171rszem\u00e9t komoly probl\u00e9m\u00e1t jelent. Egy r\u00e9sze nagyon nagy m\u00e9ret\u0171, p\u00e9ld\u00e1ul a ki\u00e9gett rak\u00e9taszakaszok, a m\u0171k\u00f6d\u00e9sk\u00e9ptelen \u0171rhaj\u00f3k \u00e9s n\u00e9h\u00e1ny, az \u0171rs\u00e9t\u00e1k sor\u00e1n elvesztett eszk\u00f6z. A legt\u00f6bbje azonban sokkal kisebb.<\/p>\n<\/div>\n

A nagy \u0171rszem\u00e9tdarabokkal val\u00f3 \u00fctk\u00f6z\u00e9s megb\u00e9n\u00edthatja, s\u0151t ak\u00e1r meg is semmis\u00edtheti az \u0171reszk\u00f6zt, ahogyan az 1996-ban a francia Cerise \u0171reszk\u00f6zzel is t\u00f6rt\u00e9nt. A kisebb \u0171rszem\u00e9tdarabok is komoly k\u00e1rokat okozhatnak, illetve vesz\u00e9lyt jelenthetnek az \u0171rs\u00e9t\u00e1t v\u00e9gz\u0151 \u0171rhaj\u00f3sra n\u00e9zve.<\/p>\n

Amikor a Hubble \u0171rt\u00e1vcs\u0151 napelemeit 2002-ben visszahozt\u00e1k a F\u00f6ldre, azok tele voltak ak\u00e1r 8 mm \u00e1tm\u00e9r\u0151j\u0171 becsap\u00f3d\u00e1si kr\u00e1terekkel.<\/p>\n

Jelenleg a teleszk\u00f3pok \u00e9s a radarok t\u00f6bb mint 12 000, ak\u00e1r 10 cm-es m\u00e9ret\u0171 \u0171rszemetet figyelnek. T\u00f6bb milli\u00f3 darab azonban t\u00fal kicsi ahhoz, hogy nyilv\u00e1ntart\u00e1sba vegy\u00e9k \u0151ket, p\u00e9ld\u00e1ul a fest\u00e9k- \u00e9s porr\u00e9szecsk\u00e9k.<\/p>\n

Norm\u00e1lis k\u00f6r\u00fclm\u00e9nyek k\u00f6z\u00f6tt ezek nem jelenten\u00e9nek vesz\u00e9lyt, de az \u0171rben a t\u00f6rmel\u00e9k nagy sebess\u00e9ggel halad. M\u00e9g a porr\u00e9szecsk\u00e9k is apr\u00f3 goly\u00f3kk\u00e9nt viselkednek. Az ESA t\u00f6bbf\u00e9le m\u00f3don is foglalkozik a t\u00f6rmel\u00e9kprobl\u00e9m\u00e1val. A Nemzetk\u00f6zi \u0170r\u00e1llom\u00e1son tal\u00e1lhat\u00f3 Columbus laborat\u00f3riumot speci\u00e1lis v\u00e9d\u0151burkolat v\u00e9di.<\/p>\n

Az Eur\u00f3pai \u0170rir\u00e1ny\u00edt\u00f3 K\u00f6zpont (ESOC) rendk\u00edv\u00fcl szigor\u00faan figyelemmel k\u00eds\u00e9ri az \u0171rszemetet. Ehhez egy 1 m\u00e9teres t\u00e1vcs\u00f6vet haszn\u00e1l a Kan\u00e1ri-szigeteken, valamint egy N\u00e9metorsz\u00e1gban elhelyezett radarrendszert. A mikroszkopikus m\u00e9ret\u0171 \u0171rszemetet az ESA Proba-1 m\u0171holdja \u00e9s az ESA egyik, a Nemzetk\u00f6zi \u0170r\u00e1llom\u00e1son v\u00e9gzett k\u00eds\u00e9rlete is figyelemmel k\u00eds\u00e9ri.
Ezek az adatok lehet\u0151v\u00e9 teszik az ESOC sz\u00e1m\u00e1ra, hogy tan\u00e1csot adjon arra vonatkoz\u00f3an, mikor kell egy \u0171reszk\u00f6zt biztons\u00e1gosabb p\u00e1ly\u00e1ra \u00e1ll\u00edtani. Emellett korai figyelmeztet\u00e9st ny\u00fajtanak azokr\u00f3l a nagy m\u00e9ret\u0171 objektumokr\u00f3l, amelyek hamarosan visszat\u00e9rnek a l\u00e9gk\u00f6rbe.<\/p>","protected":false},"excerpt":{"rendered":"
