Desv\u00e6rre er det ofte for dyrt for universiteter og skoler at sende eksperimenter med en satellit eller til Den Internationale Rumstation. Der findes dog billigere og nemmere alternativer. For eksempel har ESA\u2019s uddannelseskontor siden 2007 tilbudt flyvninger ombord p\u00e5 sm\u00e5 sondraketter og h\u00f8jtflyvende balloner. De to programmer hedder REXUS (Rocket-borne Experiments for University Students) og BEXUS (Balloon-borne Experiments for University Students).<\/p>\n<\/div>\n<p>REXUS er en ustyret, fastbr\u00e6ndstofdrevet raket i \u00e9t trin. Den kan transportere eksperimenter, der vejer omkring 30 kg, op til 100 km over Jorden. Halvvejs gennem den 6 minutter lange flyvning adskilles en nyttelastsektion, der indeholder eksperimenterne. Dette modul falder tilbage til Jorden, beskyttet af et varmeskjold. I den afsluttende del af missionen bremser faldsk\u00e6rme dets nedstigning frem mod landingen.<\/p>\n<p>BEXUS er en k\u00e6mpe ballon, der m\u00e5ler 14 m i diameter, n\u00e5r den er fyldt med helium. Den kan l\u00f8fte 100 kg op til en h\u00f8jde p\u00e5 35 km og forblive i luften i op til 5 timer. Eksperimentbeholderen (ogs\u00e5 kaldet en gondol) frig\u00f8res fra ballonen og hentes ned ved hj\u00e6lp af et faldsk\u00e6rmsystem. Nyttelasten bringes normalt tilbage til affyringsstedet en til to dage efter opsendelsen.<\/p>\n<p>B\u00e5de REXUS og BEXUS opsendes fra Kiruna i det nordlige Sverige. Der tilbydes flere flyvninger hvert \u00e5r, hvilket giver studerende en sj\u00e6lden mulighed for at designe og bygge eksperimenter, der skal flyve ud til rummets gr\u00e6nse. Man h\u00e5ber, at mange af disse studerende senere vil komme til at arbejde i den europ\u00e6iske rumfartsindustri.<\/p>","protected":false},"excerpt":{"rendered":"<p>Many young people have great ideas about experiments they\u2019d like to send into space.
