Den 21 oktober inleddes en ny era med den lyckade uppskjutningen av de tv\u00e5 f\u00f6rsta operativa rymdfarkosterna i Europas globala satellitnavigeringssystem Galileo. Den spektakul\u00e4ra, eldiga uppskjutningen var ocks\u00e5 en milstolpe f\u00f6r Europas tillg\u00e5ng till rymden. Det var f\u00f6rsta g\u00e5ngen som en ryskbyggd Sojuz-raket sk\u00f6ts upp fr\u00e5n den nya, specialbyggda uppskjutningsplatsen i Kourou i Franska Guyana.<\/p>\n<\/div>\n

Hittills har alla Sojuz-raketer skjutits upp fr\u00e5n Baikonur i Kazakstan eller Plesetsk i Ryssland. Genom att skjuta upp den fr\u00e5n Europas rymdhamn, n\u00e4ra ekvatorn, kan den europeiska Sojuz-raketen dock transportera upp till 3 ton till en \u2018geostation\u00e4r \u00f6verf\u00f6ringsbana\u2019. Detta kan j\u00e4mf\u00f6ras med endast 1,7 ton vid uppskjutningar fr\u00e5n Baikonur. Den f\u00f6rb\u00e4ttrade prestandan m\u00f6jligg\u00f6rs av den extra hastighet som jordens snabba rotation vid ekvatorn ger.<\/p>\n

IOV-satelliterna slungades ut fr\u00e5n Fregat-\u00f6versta steget<\/figcaption><\/figure>\n

Soyuz VS01-uppskjutningen, som genomf\u00f6rdes av Arianespace, inleddes kl. 10.30 GMT (12.30 CEST) och alla Soyuz-steg fungerade felfritt. Den \u00f6vre steget Fregat-MT sl\u00e4ppte ut Galileo-satelliterna f\u00f6r validering i omloppsbana (IOV) i sina m\u00e5lbana p\u00e5 23 222 km h\u00f6jd, 3 timmar och 49 minuter efter uppskjutningen.<\/p>\n

Under uppdragets inledande fas styrs Galileo IOV-satelliterna fr\u00e5n Toulouse i Frankrike av ett gemensamt team fr\u00e5n ESA och den franska rymdorganisationen (CNES). De kommer s\u00e5 sm\u00e5ningom att \u00f6verl\u00e4mnas till SpaceOpal, ett gemensamt f\u00f6retag mellan det tyska rymdcentret (DLR) och det italienska f\u00f6retaget Telespazio, f\u00f6r 90 dagars testning. N\u00e4sta \u00e5r kommer de att f\u00e5 s\u00e4llskap av ytterligare ett par IOV-satelliter. N\u00e4r konstellationen \u00e4r f\u00e4rdigst\u00e4lld kommer den att best\u00e5 av 30 satelliter som kretsar i tre olika banor.<\/p>","protected":false},"excerpt":{"rendered":"
