Le vol inaugural de Vega, le lanceur l\u00e9ger de l\u2019ESA, a \u00e9t\u00e9 programm\u00e9 pour le 13 f\u00e9vrier 2012 depuis le nouveau site de lancement du port spatial europ\u00e9en de Kourou, en Guyane fran\u00e7aise. Vega enverra en orbite un total de neuf satellites.<\/p>\n<\/div>\n

Neuf ann\u00e9es de collaboration entre l'ESA et ses partenaires auront \u00e9t\u00e9 requises pour d\u00e9velopper Vega. Le lanceur l\u00e9ger Vega, dont le nom provient de la deuxi\u00e8me \u00e9toile la plus brillante de l\u2019h\u00e9misph\u00e8re nord, a \u00e9t\u00e9 con\u00e7u pour placer en orbite polaire et en orbite basse des satellites d\u2019un poids compris entre 300 kilos et 2 tonnes, afin de mener de nombreuses missions scientifiques et d\u2019observation de la Terre. Vega se distingue par une taille de 30 m\u00e8tres, un diam\u00e8tre de 3 m\u00e8tres et un poids total de 137 tonnes !<\/p>\n

Comme la plupart des lanceurs l\u00e9gers, Vega est capable de placer plusieurs satellites en orbite. Pendant son vol inaugural VV01, Vega transportera le satellite LARES (acronyme de Laser Relativity Satellite), un microsatellite de d\u00e9monstration technologique appel\u00e9 ALMASat-1 et sept petits satellites CubeSats. Ces satellites, d\u2019une masse maximale d\u2019un kilo, ont \u00e9t\u00e9 d\u00e9velopp\u00e9s au cours des quatre derni\u00e8res ann\u00e9es par plus de 250 \u00e9tudiants issus de six pays diff\u00e9rents. Les CubeSats peuvent \u00eatre contr\u00f4l\u00e9s par des chercheurs ou des radioamateurs depuis des stations au sol. De plus, ces pico-satellites fournissent une premi\u00e8re approche pratique \u00e0 tous les \u00e9tudiants en astronautique.<\/p>\n

Le lanceur Vega, enti\u00e8rement assembl\u00e9, se dresse \u00e0 pr\u00e9sent sur sa zone de lancement \u00e0 Kourou. Les pr\u00e9paratifs pour son vol inaugural depuis le port spatial europ\u00e9en entrent dans leur derni\u00e8re ligne droite. Les derni\u00e8res \u00e9tapes \u00e0 accomplir sont la v\u00e9rification finale de l\u2019assemblage, la r\u00e9p\u00e9tition du compte \u00e0 rebours et le remplissage en ergols du lanceur. Une fois ces op\u00e9rations termin\u00e9es, Vega sera pr\u00eat \u00e0 d\u00e9coller !<\/p>","protected":false},"excerpt":{"rendered":"
