P\u0159\u00edtomnost vesm\u00edrn\u00e9ho odpadu p\u0159edstavuje zna\u010dnou hrozbu pro v\u00fdzkum vesm\u00edru. Vysokorychlostn\u00ed sr\u00e1\u017eky odpadu mohou vytv\u00e1\u0159et je\u0161t\u011b v\u00edce odpadu, co\u017e vede k \u0159et\u011bzov\u00e9 reakci zn\u00e1m\u00e9 jako Kessler\u016fv syndrom. To by nakonec mohlo znemo\u017enit lidem p\u0159\u00edstup do vesm\u00edru.<\/p>\n\n
Japonsk\u00e1 kosmick\u00e1 agentura JAXA vyvinula novou metodu \u0159e\u0161en\u00ed probl\u00e9mu vesm\u00edrn\u00e9ho odpadu. Jejich pl\u00e1n zahrnuje ob\u0159\u00ed kabel z dr\u00e1t\u016f, kter\u00fd generuje elektrick\u00fd proud. Tento proud vytv\u00e1\u0159\u00ed elektromagnetick\u00e9 pole, kter\u00e9 p\u0159itahuje odpad a odtla\u010duje s\u00ed\u0165 od zemsk\u00e9ho magnetick\u00e9ho pole.<\/p>\n\n
Jakmile s\u00ed\u0165 nasb\u00edr\u00e1 dostatek odpadu, dostane pokyn ke zpomalen\u00ed a opu\u0161t\u011bn\u00ed ob\u011b\u017en\u00e9 dr\u00e1hy.

Na rozd\u00edl od s\u00edt\u011b pou\u017e\u00edvan\u00e9 v oce\u00e1nu jde o s\u00ed\u0165 z hlin\u00edkov\u00fdch a ocelov\u00fdch dr\u00e1t\u016f, kter\u00e1 vis\u00ed z bezpilotn\u00ed kosmick\u00e9 lodi. Senzory na s\u00edti detekuj\u00ed mal\u00e9 kusy odpadu a automaticky s\u00ed\u0165 zarovnaj\u00ed tak, aby je p\u0159it\u00e1hly.<\/p>\n\n
Ob\u011b\u017en\u00e1 dr\u00e1ha s\u00edt\u011b je upravena elektrick\u00fdm proudem proch\u00e1zej\u00edc\u00edm dr\u00e1ty, kter\u00fd vytv\u00e1\u0159\u00ed elektromagnetick\u00e9 pole p\u0159itahuj\u00edc\u00ed odpad. Toto pole tak\u00e9 odpuzuje s\u00ed\u0165 od zemsk\u00e9ho magnetick\u00e9ho pole a br\u00e1n\u00ed tomu, aby byla sta\u017eena dol\u016f.<\/p>\n\n
