Rumskrot udg\u00f8r et stort problem. Nogle af genstandene er meget store, s\u00e5som udbr\u00e6ndte rakettrin, udtjente rumfart\u00f8jer og enkelte redskaber, der er g\u00e5et tabt under rumvandringer. Det meste af det er dog langt mindre.<\/p>\n<\/div>\n

Kollisioner med store stykker rumskrot kan s\u00e6tte et rumfart\u00f8j ud af drift eller endda \u00f8del\u00e6gge det, som det skete for det franske rumfart\u00f8j Cerise i 1996. Mindre rumskrot kan ogs\u00e5 for\u00e5rsage alvorlige skader eller udg\u00f8re en fare for en astronaut, der udf\u00f8rer et rumvandring.<\/p>\n

Da Hubble-rumteleskopets solpaneler blev bragt tilbage til Jorden i 2002, var de overs\u00e5et med nedslagskratere med en diameter p\u00e5 op til 8 mm.<\/p>\n

I dag overv\u00e5ger teleskoper og radar mere end 12.000 stykker rumskrot, der er helt ned til 10 cm i st\u00f8rrelse. Mange millioner stykker er for sm\u00e5 til at blive registreret, f.eks. malingsflager og st\u00f8v.<\/p>\n

Normalt udg\u00f8r disse ingen trussel, men i rummet bev\u00e6ger rumskrot sig med h\u00f8j hastighed. Selv st\u00f8vpartikler fungerer som sm\u00e5 kugler. ESA tackler problemet med rumskrot p\u00e5 forskellige m\u00e5der. Columbus-laboratoriet p\u00e5 Den Internationale Rumstation er beskyttet af en s\u00e6rlig afsk\u00e6rmning.<\/p>\n

Det Europ\u00e6iske Rumoperationscenter (ESOC) overv\u00e5ger rumskrot meget n\u00f8je. Centret benytter et 1 meter teleskop p\u00e5 De Kanariske \u00d8er og et radarsystem i Tyskland. Mikroskopisk rumskrot overv\u00e5ges desuden af ESA\u2019s Proba-1-satellit og et ESA-eksperiment p\u00e5 Den Internationale Rumstation.
Disse oplysninger g\u00f8r det muligt for ESOC at r\u00e5dgive om, hvorn\u00e5r et rumfart\u00f8j b\u00f8r flyttes til en sikrere bane. De giver desuden tidlig advarsel om store objekter, der er ved at tr\u00e6nge ind i atmosf\u00e6ren igen.<\/p>","protected":false},"excerpt":{"rendered":"
