V roce 1957 se Sputnik stal prvn\u00ed um\u011blou dru\u017eic\u00ed, kter\u00e1 \u00fasp\u011b\u0161n\u011b dos\u00e1hla vesm\u00edru. Od t\u00e9 doby byly vypu\u0161t\u011bny tis\u00edce dru\u017eic. Tyto dru\u017eice, kter\u00e9 dnes ob\u00edhaj\u00ed kolem na\u0161\u00ed planety, n\u00e1m umo\u017e\u0148uj\u00ed naj\u00edt cestu dom\u016f odkudkoli, kdykoli komunikovat s lidmi po cel\u00e9m sv\u011bt\u011b, sledovat mizej\u00edc\u00ed lesy a ledov\u00e9 \u010depice a dokonce p\u0159edpov\u00eddat p\u0159\u00edrodn\u00ed katastrofy.<\/p>\n

\u00c9ra satelit\u016f v\u0161ak tak\u00e9 zaplnila prostor kolem Zem\u011b velk\u00fdmi kusy neaktivn\u00edho kovu. Kolem planety ob\u00edh\u00e1 odhadem 30 000 velk\u00fdch kus\u016f vesm\u00edrn\u00e9ho odpadu. Pat\u0159\u00ed sem v\u0161e od vy\u0159azen\u00fdch satelit\u016f p\u0159es odhozen\u00e9 \u010d\u00e1sti raket a\u017e po rukavice astronaut\u016f. A tento po\u010det st\u00e1le roste!<\/p>\n

Krom\u011b toho se ve vesm\u00edru nach\u00e1zej\u00ed miliony men\u0161\u00edch \u00falomk\u016f, jako jsou matice, \u0161rouby a dokonce i kousky barvy. Mnoh\u00e9 z nich se pohybuj\u00ed kolem Zem\u011b rychlost\u00ed 7 km za sekundu. P\u0159i t\u00e9to rychlosti by kousek barvy mohl m\u00edt stejn\u00fd dopad jako motocykl jedouc\u00ed rychlost\u00ed 95 km za hodinu!<\/p>\n

Takov\u00fd n\u00e1raz by po\u0161kodil jakoukoli dru\u017eici nebo vesm\u00edrnou stanici a vytvo\u0159il by nov\u00e9 kusy nebezpe\u010dn\u00e9ho vesm\u00edrn\u00e9ho odpadu. ESA proto pov\u011b\u0159ila n\u011bkter\u00e9 ze sv\u00fdch nejlep\u0161\u00edch odborn\u00edk\u016f, aby na\u0161li \u0159e\u0161en\u00ed tohoto slo\u017eit\u00e9ho probl\u00e9mu. A zd\u00e1 se, \u017ee mo\u017en\u00e1 pr\u00e1v\u011b na\u0161li ide\u00e1ln\u00ed \u0159e\u0161en\u00ed, a to s vyu\u017eit\u00edm jedn\u00e9 z nejstar\u0161\u00edch technologi\u00ed lidstva \u2013 ryb\u00e1\u0159sk\u00e9 s\u00edt\u011b.<\/p>\n

Pomoc\u00ed speci\u00e1ln\u011b navr\u017een\u00fdch s\u00edt\u00ed vyst\u0159elen\u00fdch z kosmick\u00e9 lodi budeme schopni zachytit nefunk\u010dn\u00ed satelity a sn\u00e9st je na zem. Tento geni\u00e1ln\u00ed n\u00e1pad se v sou\u010dasn\u00e9 dob\u011b testuje ve stavu bezt\u00ed\u017ee a pokud v\u0161e p\u016fjde podle pl\u00e1nu, mise ESA s n\u00e1zvem \u2018e.Deorbit\u2019 bude zah\u00e1jena v roce 2021 a my si budeme moci p\u00e1r satelit\u016f chytit!<\/p>\n

Zaj\u00edmavost:<\/b> Aby satelit z\u016fstal ve vesm\u00edru a nespadl zp\u011bt na Zemi, mus\u00ed ob\u00edhat kolem na\u0161\u00ed planety rychlost\u00ed v\u00edce ne\u017e 28 200 kilometr\u016f za hodinu!<\/p>","protected":false},"excerpt":{"rendered":"
