Rymdskrot \u00e4r ett stort problem. En del av det \u00e4r mycket stort, till exempel utbr\u00e4nda raketsteg, uttj\u00e4nta rymdfarkoster och en del verktyg som tappats bort under rymdpromenader. Det mesta \u00e4r dock betydligt mindre.<\/p>\n<\/div>\n

Kollisioner med stora rymdskrotbitar kan s\u00e4tta ett rymdfarkost ur drift eller till och med f\u00f6rst\u00f6ra det, vilket h\u00e4nde med den franska rymdfarkosten Cerise \u00e5r 1996. \u00c4ven mindre rymdskrot kan orsaka stora skador eller utg\u00f6ra en fara f\u00f6r en astronaut som utf\u00f6r en rymdpromenad.<\/p>\n

N\u00e4r solpanelerna fr\u00e5n rymdteleskopet Hubble \u00e5terf\u00f6rdes till jorden \u00e5r 2002 var de \u00f6vers\u00e5llade med nedslagskratrar med en diameter p\u00e5 upp till 8 mm.<\/p>\n

I dag \u00f6vervakar teleskop och radar mer \u00e4n 12 000 rymdskrotbitar som \u00e4r s\u00e5 sm\u00e5 som 10 cm. M\u00e5nga miljoner bitar \u00e4r f\u00f6r sm\u00e5 f\u00f6r att kunna registreras, till exempel f\u00e4rgfl\u00e4ckar och damm.<\/p>\n

Normalt sett skulle dessa inte utg\u00f6ra n\u00e5got hot, men i rymden r\u00f6r sig rymdskrot med h\u00f6g hastighet. Till och med dammpartiklar fungerar som sm\u00e5 kulor. ESA arbetar med att l\u00f6sa problemet med rymdskrot p\u00e5 olika s\u00e4tt. Columbus-laboratoriet p\u00e5 den internationella rymdstationen skyddas av en speciell sk\u00e4rm.<\/p>\n

Europeiska rymdoperationscentret (ESOC) \u00f6vervakar rymdskrot mycket noggrant. Man anv\u00e4nder ett 1 meter stort teleskop p\u00e5 Kanarie\u00f6arna och ett radarsystem i Tyskland. Mikroskopiskt skrot \u00f6vervakas dessutom av ESA:s satellit Proba-1 och ett ESA-experiment p\u00e5 den internationella rymdstationen.
Med hj\u00e4lp av denna information kan ESOC ge r\u00e5d om n\u00e4r en rymdfarkost b\u00f6r flyttas till en s\u00e4krare omloppsbana. Den ger ocks\u00e5 tidiga varningar om stora f\u00f6rem\u00e5l som \u00e4r p\u00e5 v\u00e4g att \u00e5terintr\u00e4da i atmosf\u00e4ren.<\/p>","protected":false},"excerpt":{"rendered":"
