M\u00e5nga ungdomar har fantastiska id\u00e9er om experiment som de g\u00e4rna skulle vilja skicka upp i rymden. Tyv\u00e4rr \u00e4r det ofta f\u00f6r dyrt f\u00f6r universitet och skolor att skicka upp experiment med en satellit eller till den internationella rymdstationen. Det finns dock billigare och enklare alternativ. Till exempel har ESA:s utbildningsavdelning sedan 2007 erbjudit flygningar ombord p\u00e5 sm\u00e5 sondraketer och h\u00f6gh\u00f6jdsballonger. De tv\u00e5 programmen kallas REXUS (Rocket-borne Experiments for University Students) och BEXUS (Balloon-borne Experiments for University Students).<\/p>\n<\/div>\n

REXUS \u00e4r en ostyrd, enstegsraket som drivs med fast br\u00e4nsle. Den kan transportera experiment som v\u00e4ger cirka 30 kg upp till 100 km \u00f6ver jordytan. Halvv\u00e4gs in i den 6 minuter l\u00e5nga flygningen separeras en lastsektion som inneh\u00e5ller experimenten. Denna modul faller tillbaka till jorden, skyddad av ett v\u00e4rmeskydd. Under uppdragets sista del bromsar fallsk\u00e4rmar dess nedstigning inf\u00f6r landningen.<\/p>\n

BEXUS \u00e4r en enorm ballong som har en diameter p\u00e5 14 m n\u00e4r den \u00e4r fylld med helium. Den kan lyfta 100 kg till en h\u00f6jd av 35 km och h\u00e5lla sig i luften i upp till 5 timmar. Experimentbeh\u00e5llaren (kallad gondol) sl\u00e4pps fr\u00e5n ballongen och \u00e5tervinns med hj\u00e4lp av ett fallsk\u00e4rmsystem. Lasten \u00e5terf\u00f6rs vanligtvis till uppskjutningsplatsen en till tv\u00e5 dagar efter uppskjutningen.<\/p>\n

B\u00e5de REXUS och BEXUS skjuts upp fr\u00e5n Kiruna i norra Sverige. Flera flygningar anordnas varje \u00e5r, vilket ger studenter en unik m\u00f6jlighet att utforma och bygga experiment som ska flyga till rymdens gr\u00e4ns. F\u00f6rhoppningen \u00e4r att m\u00e5nga av dessa studenter senare ska arbeta inom den europeiska rymdindustrin.<\/p>","protected":false},"excerpt":{"rendered":"
