Paljudel noortel on suurep\u00e4rased ideed katsete kohta, mida nad sooviksid kosmosesse saata. Kahjuks on katsete l\u00e4biviimine satelliidil v\u00f5i Rahvusvahelisel Kosmosejaamal \u00fclikoolide ja koolide jaoks sageli liiga kallis. Siiski on olemas odavamad ja lihtsamad alternatiivid. N\u00e4iteks on ESA haridusosakond alates 2007. aastast pakkunud v\u00f5imalust saata katseid lendu v\u00e4ikeste sondrakettide ja k\u00f5rgelennuliste \u00f5hupallide pardal. Need kaks programmi on tuntud nimetustega REXUS (Rocket-borne Experiments for University Students) ja BEXUS (Balloon-borne Experiments for University Students).<\/p>\n<\/div>\n

REXUS on juhitamatu, tahkek\u00fctusel t\u00f6\u00f6tav \u00fcheastmeline rakett. See suudab viia umbes 30 kg kaaluvaid katseid kuni 100 km k\u00f5rgusele Maa kohal. 6-minutilise lennu keskel eraldub katseseadmeid sisaldav kasulast. See moodul langeb tagasi Maale, kaitstud soojuskilbi poolt. Missiooni viimases osas aeglustavad langevarjud selle langemist maandumiseks.<\/p>\n

BEXUS on hiiglaslik \u00f5hupall, mille l\u00e4bim\u00f5\u00f5t on heeliumiga t\u00e4idetuna 14 m. See suudab t\u00f5sta 100 kg 35 km k\u00f5rgusele ja p\u00fcsida \u00f5hus kuni 5 tundi. Katseseade (nn gondel) vabastatakse \u00f5hupallist ja toodakse tagasi langevarjus\u00fcsteemi abil. Kasulik koorem tuuakse tavaliselt tagasi stardipaika \u00fcks kuni kaks p\u00e4eva p\u00e4rast \u00f5hkut\u00f5usu.<\/p>\n

Nii REXUS kui ka BEXUS lastakse \u00f5hku Kirunast P\u00f5hja-Rootsis. Igal aastal korraldatakse mitu lendu, mis annavad \u00f5pilastele haruldase v\u00f5imaluse kavandada ja ehitada katseid, mis lendavad kosmoseservale. Loodetakse, et paljud neist \u00f5pilastest hakkavad edaspidi t\u00f6\u00f6tama Euroopa kosmoset\u00f6\u00f6stuses.<\/p>","protected":false},"excerpt":{"rendered":"
