Mul\u021bi tineri au idei grozave despre experimentele pe care ar dori s\u0103 le trimit\u0103 \u00een spa\u021biu. Din p\u0103cate, lansarea experimentelor la bordul unui satelit sau al Sta\u021biei Spa\u021biale Interna\u021bionale este adesea prea costisitoare pentru universit\u0103\u021bi \u0219i \u0219coli. Cu toate acestea, exist\u0103 alternative mai ieftine \u0219i mai u\u0219or de pus \u00een practic\u0103. De exemplu, Biroul de Educa\u021bie al ESA ofer\u0103, \u00eenc\u0103 din 2007, zboruri la bordul unor rachete de sondare de mici dimensiuni \u0219i al unor baloane de mare altitudine. Cele dou\u0103 programe sunt cunoscute sub denumirile de REXUS (Experimente transportate de rachete pentru studen\u021bi) \u0219i BEXUS (Experimente transportate de baloane pentru studen\u021bi).<\/p>\n<\/div>\n

REXUS este o rachet\u0103 neghidat\u0103, cu combustibil solid, cu o singur\u0103 treapt\u0103. Aceasta poate transporta experimente cu o greutate de aproximativ 30 kg la o altitudine de p\u00e2n\u0103 la 100 km deasupra P\u0103m\u00e2ntului. La jum\u0103tatea zborului de 6 minute, sec\u021biunea de \u00eenc\u0103rc\u0103tur\u0103 util\u0103 care con\u021bine experimentele se separ\u0103. Acest modul cade \u00eenapoi pe P\u0103m\u00e2nt, protejat de un scut termic. \u00cen ultima parte a misiunii, para\u0219utele \u00eei \u00eencetinesc cobor\u00e2rea pentru aterizare.<\/p>\n

BEXUS este un balon uria\u0219, cu un diametru de 14 m atunci c\u00e2nd este umplut cu heliu. Acesta poate ridica 100 kg la o \u00een\u0103l\u021bime de 35 km \u0219i poate r\u0103m\u00e2ne \u00een aer p\u00e2n\u0103 la 5 ore. Contenorul experimental (cunoscut sub numele de gondol\u0103) este eliberat din balon \u0219i recuperat cu ajutorul unui sistem de para\u0219ute. Sarcina util\u0103 este adus\u0103 de obicei \u00eenapoi la locul de lansare la una sau dou\u0103 zile dup\u0103 decolare.<\/p>\n

At\u00e2t REXUS, c\u00e2t \u0219i BEXUS sunt lansate din Kiruna, \u00een nordul Suediei. \u00cen fiecare an sunt organizate mai multe zboruri, oferind studen\u021bilor o ocazie rar\u0103 de a proiecta \u0219i construi experimente care vor ajunge p\u00e2n\u0103 la marginea spa\u021biului. Se sper\u0103 c\u0103 mul\u021bi dintre ace\u0219ti studen\u021bi vor ajunge s\u0103 lucreze \u00een industria spa\u021bial\u0103 european\u0103.<\/p>","protected":false},"excerpt":{"rendered":"
