Mnoho mlad\u00fdch lid\u00ed m\u00e1 skv\u011bl\u00e9 n\u00e1pady na experimenty, kter\u00e9 by r\u00e1di vyslali do vesm\u00edru. Bohu\u017eel je pro univerzity a \u0161koly \u010dasto p\u0159\u00edli\u0161 n\u00e1kladn\u00e9 vys\u00edlat experimenty na dru\u017eici nebo na Mezin\u00e1rodn\u00ed vesm\u00edrnou stanici. Existuj\u00ed v\u0161ak levn\u011bj\u0161\u00ed a jednodu\u0161\u0161\u00ed alternativy. Nap\u0159\u00edklad vzd\u011bl\u00e1vac\u00ed odd\u011blen\u00ed Evropsk\u00e9 kosmick\u00e9 agentury (ESA) nab\u00edz\u00ed ji\u017e od roku 2007 lety na palub\u011b mal\u00fdch sond\u00e1\u017en\u00edch raket a balon\u016f pro lety do vysok\u00fdch v\u00fd\u0161ek. Tyto dva programy se naz\u00fdvaj\u00ed REXUS (Rocket-borne Experiments for University Students) a BEXUS (Balloon-borne Experiments for University Students).<\/p>\n<\/div>\n

REXUS je ne\u0159\u00edzen\u00e1 jednostup\u0148ov\u00e1 raketa na pevn\u00e9 palivo. Je schopna vyn\u00e9st experimenty o hmotnosti p\u0159ibli\u017en\u011b 30 kg do v\u00fd\u0161ky a\u017e 100 km nad Zem\u00ed. V polovin\u011b \u0161estiminutov\u00e9ho letu se odd\u011bl\u00ed \u010d\u00e1st s u\u017eite\u010dn\u00fdm zat\u00ed\u017een\u00edm, kter\u00e1 obsahuje experimenty. Tento modul se vrac\u00ed zp\u011bt na Zemi, chr\u00e1n\u011bn tepeln\u00fdm \u0161t\u00edtem. V z\u00e1v\u011bre\u010dn\u00e9 f\u00e1zi mise zpomaluj\u00ed jeho sestup pad\u00e1ky, aby mohl p\u0159ist\u00e1t.<\/p>\n

BEXUS je obrovsk\u00fd bal\u00f3n, jeho\u017e pr\u016fm\u011br po napln\u011bn\u00ed h\u00e9liem \u010din\u00ed 14 m.

N\u00e1doba s experimentem (tzv. gondola) se uvoln\u00ed z bal\u00f3nu a je zachycena pomoc\u00ed pad\u00e1kov\u00e9ho syst\u00e9mu. N\u00e1klad se obvykle vrac\u00ed na m\u00edsto startu jeden a\u017e dva dny po vzletu.<\/p>\n

Programy REXUS i BEXUS se spou\u0161t\u011bj\u00ed z Kiruny v severn\u00edm \u0160v\u00e9dsku. Ka\u017ed\u00fd rok se kon\u00e1 n\u011bkolik let\u016f, kter\u00e9 student\u016fm nab\u00edzej\u00ed vz\u00e1cnou p\u0159\u00edle\u017eitost navrhnout a sestrojit experimenty, kter\u00e9 polet\u00ed a\u017e na hranici vesm\u00edru. Douf\u00e1me, \u017ee mnoho z t\u011bchto student\u016f bude v budoucnu pracovat v evropsk\u00e9m kosmick\u00e9m pr\u016fmyslu.<\/p>","protected":false},"excerpt":{"rendered":"
