Nekateri med njimi so zelo veliki, na primer izgorele stopnje raket, neuporabna vesoljska plovila in nekaj orodja, ki se je izgubilo med vesoljskimi sprehodi. Ve\u010dina pa je precej manj\u0161a.<\/p>\n<\/div>\n<p>Trki z velikimi kosmi vesoljskih odpadkov lahko onesposobijo ali celo uni\u010dijo vesoljsko plovilo, kot se je zgodilo francoskemu vesoljskemu plovilu \u00bbCerise\u00ab leta 1996. Tudi manj\u0161i odpadki lahko povzro\u010dijo veliko \u0161kodo ali ogro\u017eajo astronavta med vesoljskim sprehodom.<\/p>\n<p>Ko so leta 2002 son\u010dne celice vesoljskega teleskopa Hubble vrnili na Zemljo, so bile posejane z udarnimi kraterji s premerom do 8 mm.<\/p>\n<p>Danes teleskopi in radarji spremljajo ve\u010d kot 12.000 kosov vesoljskih odpadkov, velikih do 10 cm. Ve\u010d milijonov kosov je premajhnih, da bi jih bilo mogo\u010de zabele\u017eiti, na primer delci barve in prahu.<\/p>\n<p>Obi\u010dajno ti ne bi predstavljali nevarnosti, vendar se v vesolju vesoljski odpadki gibljejo z visoko hitrostjo. Celo delci prahu delujejo kot majhne krogle. ESA se s problemom vesoljskih odpadkov spopada na razli\u010dne na\u010dine. Laboratorij Columbus na Mednarodni vesoljski postaji je za\u0161\u010diten s posebnim \u0161\u010ditom.<\/p>\n<p>Evropski center za vesoljske operacije (ESOC) zelo pozorno spremlja vesoljske odpadke. Pri tem uporablja 1-metrski teleskop na Kanarskih otokih in radarski sistem v Nem\u010diji. Mikroskopske odpadke spremlja tudi satelit Proba-1 agencije ESA ter eksperiment agencije ESA na Mednarodni vesoljski postaji.<br \/>Na podlagi teh podatkov lahko ESOC svetuje, kdaj je treba vesoljsko plovilo preusmeriti na varnej\u0161o orbito. Prav tako omogo\u010dajo zgodnje opozarjanje na velike predmete, ki se bodo kmalu vrnili v atmosfero.<\/p>","protected":false},"excerpt":{"rendered":"<p>Space junk is a major problem.
