Osa sellest on v\u00e4ga suur, n\u00e4iteks l\u00e4bi p\u00f5lenud raketiastmed, t\u00f6\u00f6k\u00f5lbmatud kosmoses\u00f5idukid ja m\u00f5ned kosmosek\u00f5nnil kaduma l\u00e4inud t\u00f6\u00f6riistad. Enamik sellest on aga palju v\u00e4iksem.<\/p>\n<\/div>\n<p>Kokkup\u00f5rked suurte kosmoseprahi t\u00fckkidega v\u00f5ivad kosmoselaeva t\u00f6\u00f6k\u00f5lbmatuks muuta v\u00f5i isegi h\u00e4vitada, nagu juhtus 1996. aastal Prantsuse kosmoselaevaga \u201eCerise\u201d. Ka v\u00e4iksemad kosmoseprahi t\u00fckid v\u00f5ivad p\u00f5hjustada suuri kahjustusi v\u00f5i ohustada kosmoses k\u00f5ndivat astronauti.<\/p>\n<p>Kui Hubble\u2019i kosmoseteleskoobi p\u00e4ikesepaneelid toodi 2002. aastal tagasi Maale, olid need kaetud kuni 8 mm l\u00e4bim\u00f5\u00f5duga kokkup\u00f5rkekraatritega.<\/p>\n<p>T\u00e4nap\u00e4eval j\u00e4lgivad teleskoobid ja radarid enam kui 12 000 kosmoser\u00e4mpsu t\u00fckki, mille suurus ulatub kuni 10 cm-ni. Mitmed miljonid t\u00fckid on liiga v\u00e4ikesed, et neid registreerida, n\u00e4iteks v\u00e4rvi- ja tolmuk\u00fcbemed.<\/p>\n<p>Tavaliselt ei kujutaks need endast ohtu, kuid kosmoses liiguvad kosmosepraht ja -j\u00e4\u00e4gid suure kiirusega. Isegi tolmuosakesed k\u00e4ituvad nagu pisikesed kuulid. ESA tegeleb kosmoseprahi probleemiga mitmel viisil. Rahvusvahelise kosmosejaama laborit \u201eColumbus\u201c kaitseb spetsiaalne kilp.<\/p>\n<p>Euroopa Kosmosekeskus (ESOC) j\u00e4lgib kosmoseprahti v\u00e4ga t\u00e4helepanelikult. Selleks kasutatakse Kanaari saartel asuvat 1-meetrist teleskoopi ja Saksamaal asuvat radaris\u00fcsteemi. Mikroskoopilist prahti j\u00e4lgitakse ka ESA satelliidi Proba-1 ja Rahvusvahelisel Kosmosejaamal l\u00e4biviidava ESA eksperimendi abil.<br \/>Selle teabe abil saab ESOC anda soovitusi selle kohta, millal tuleks kosmoselaev viia ohutumale orbiidile. Samuti v\u00f5imaldab see varakult hoiatada suurte objektide eest, mis on peagi sisenemas atmosf\u00e4\u00e4ri.<\/p>","protected":false},"excerpt":{"rendered":"<p>Space junk is a major problem.
