2002 m\u00e1rcius\u00e1ban a Hubble \u0171rt\u00e1vcs\u0151 napelem-paneleit visszahozta a F\u00f6ldre. Az \u0171rben t\u00f6lt\u00f6tt nyolc \u00e9v ut\u00e1n az ESA \u00e1ltal sz\u00e1ll\u00edtott panelek tele voltak ak\u00e1r 8 mm \u00e1tm\u00e9r\u0151j\u0171 becsap\u00f3d\u00e1si kr\u00e1terekkel.<\/p>\n<\/div>\n

A kr\u00e1terek gyorsan mozg\u00f3 \u0171rszem\u00e9t-darabok hat\u00e1s\u00e1ra keletkeztek. Mivel gyorsabban haladnak, mint egy goly\u00f3, m\u00e9g egy fest\u00e9kpelyhek is komoly k\u00e1rokat okozhatnak egy \u0171rhaj\u00f3ban. 2003 v\u00e9g\u00e9n mintegy 10 000 darab \u0171rszemetet k\u00f6vettek nyomon. Ezek k\u00f6z\u00f6tt voltak m\u00e1r nem m\u0171k\u00f6d\u0151 \u0171rhaj\u00f3k, r\u00e9gi rak\u00e9taszakaszok \u00e9s n\u00e9h\u00e1ny, \u0171rs\u00e9t\u00e1k sor\u00e1n elvesztett szersz\u00e1m is.<\/p>\n

Sokkal t\u00f6bb t\u00e1rgy van, amely t\u00fal kicsi ahhoz, hogy nyilv\u00e1ntart\u00e1sba vegy\u00e9k. Lehet, hogy f\u00e9lmilli\u00f3 olyan t\u00e1rgy l\u00e9tezik, amelynek \u00e1tm\u00e9r\u0151je 1\u201310 cm \u2013 de a pontos sz\u00e1mot senki sem ismeri. Az ESA k\u00fcl\u00f6nb\u00f6z\u0151 m\u00f3dszerekkel igyekszik megoldani az \u0171rszem\u00e9t-probl\u00e9m\u00e1t. A Nemzetk\u00f6zi \u0170r\u00e1llom\u00e1son tal\u00e1lhat\u00f3 Columbus laborat\u00f3riumot speci\u00e1lis v\u00e9d\u0151burkolattal fogj\u00e1k ell\u00e1tni.<\/p>\n

Az ESA n\u00e9metorsz\u00e1gi \u00e9s hollandiai tud\u00f3sai nyilv\u00e1ntart\u00e1st vezetnek az \u00f6sszes ismert, a F\u00f6ld k\u00f6r\u00fcl kering\u0151 t\u00e1rgyr\u00f3l. Ezeket az adatokat felhaszn\u00e1lj\u00e1k az \u0171rszem\u00e9t vizsg\u00e1lat\u00e1ra \u00e9s a lehets\u00e9ges \u00fctk\u00f6z\u00e9sekre vonatkoz\u00f3 el\u0151zetes figyelmeztet\u00e9sek kiad\u00e1s\u00e1ra.<\/p>\n
