Ranskan Guayanassa Kouroun l\u00e4hell\u00e4 sijaitseva Euroopan avaruuskeskuks on yksi maailman nykyaikaisimmista ja tehokkaimmista laukaisupaikoista. Viimeisten 35 vuoden aikana on rakennettu kolme laukaisualustaa ja lukuisia muita rakennuksia tukemaan eurooppalaista avaruusalan teollisuutta.<\/p>\n<\/div>\n

Kaikki Euroopan Ariane-raketit on laukaistu Ranskan Guayanasta. Avaruuskeskuksen ELA-3-laukaisualusta rakennettiin nimenomaan uutta Ariane-5-raskaskantorakettia varten. Se on suunniteltu k\u00e4sittelem\u00e4\u00e4n jopa 10 Ariane-5-lentoa vuodessa.<\/p>\n

ELA-3:n pinta-ala on 3 x 5 km \u2013 mik\u00e4 vastaa yli 1 500 jalkapallokentt\u00e4\u00e4. Laukaisualustan lis\u00e4ksi alueeseen kuuluu rakennuksia, joissa raketteja ja satelliitteja valmistellaan, sek\u00e4 laitos, jossa valmistetaan polttoainetta Ariane-5-raketin kiinte\u00e4n polttoaineen apuraketteihin.<\/p>\n

Kontteihin pakatut satelliitit saapuvat lentokoneella Rochambeaun lentokent\u00e4lle Cayenneen. Suuret rakettivaiheet tuodaan Euroopasta erikoiskuljetusaluksella ja puretaan Pariacabon satamassa. Satelliitit ja rakettivaiheet kuljetetaan maanteitse l\u00e4heiselle avaruuskeskukselle.<\/p>\n

Ariane-5-raketin kokoonpano alkaa 58 metri\u00e4 korkeassa laukaisualustan kokoonpanorakennuksessa. 13 p\u00e4iv\u00e4n kuluttua raketti rullataan ulos siirrett\u00e4v\u00e4lle laukaisualustalle ja siirret\u00e4\u00e4n hitaasti rautatiet\u00e4 pitkin 90 metri\u00e4 korkeaan lopullisen kokoonpanon rakennukseen.<\/p>","protected":false},"excerpt":{"rendered":"
