Euroopan avaruusj\u00e4rjest\u00f6 (ESA) perustettiin vuonna 1975, ja siihen kuuluu 22 maata. Suurin osa n\u00e4ist\u00e4 maista on liian pieni\u00e4 voidakseen osallistua suuriin avaruushankkeisiin yksin.<\/p>\n

Toimimalla yhdess\u00e4 tiimin\u00e4 he voivat olla t\u00e4rke\u00e4ss\u00e4 roolissa monissa erilaisissa avaruustoiminnoissa.<\/p>\n<\/div>\n

Euroopan maat valmistavat nyky\u00e4\u00e4n joitakin maailman t\u00e4rkeimmist\u00e4 raketeista ja satelliiteista. ESA:n j\u00e4senmaat ovat my\u00f6s johtavia satelliittien rakentajia. N\u00e4m\u00e4 yritykset osallistuvat satelliittien suunnitteluun, rakentamiseen, testaamiseen ja laukaisemiseen, mik\u00e4 auttaa parantamaan el\u00e4m\u00e4\u00e4mme t\u00e4\u00e4ll\u00e4 maapallolla huomattavasti. Miljoonat ihmiset k\u00e4ytt\u00e4v\u00e4t eurooppalaisia satelliitteja p\u00e4ivitt\u00e4in. Ne kertovat meille, millainen s\u00e4\u00e4 on tulossa, miten maata k\u00e4ytet\u00e4\u00e4n ja miten l\u00f6yd\u00e4mme tiens\u00e4 teill\u00e4. K\u00e4yt\u00e4mme niit\u00e4 my\u00f6s puhelimissa ja t\u00e4htitieteess\u00e4.<\/p>\n

ESA:lla on 22 j\u00e4senvaltiota, jotka on merkitty tummanharmaalla.

Merkitty keskiharmaalla: My\u00f6s Kanada on neuvoston j\u00e4sen ja osallistuu joihinkin hankkeisiin yhteisty\u00f6sopimuksen puitteissa. Slovenia on liit\u00e4nn\u00e4isj\u00e4sen. Seitsem\u00e4ll\u00e4 muulla EU-valtiolla on yhteisty\u00f6sopimukset ESA:n kanssa: Bulgaria, Kroatia, Kypros, Latvia, Liettua, Malta ja Slovakia.<\/p>","protected":false},"excerpt":{"rendered":"
