Les nouvelles missions de l\u2019ESA et des diff\u00e9rentes agences spatiales mondiales seront \u00e9galement pr\u00e9sent\u00e9es, plus particuli\u00e8rement le programme Sentinelles et les futures missions m\u00e9t\u00e9orologiques et d\u2019exploration de la Terre. Plus de 1 700 pr\u00e9sentations - portant sur des th\u00e8mes aussi vari\u00e9s que l'oc\u00e9anographie, l'atmosph\u00e8re, le climat et la m\u00e9t\u00e9orologie - seront organis\u00e9es pendant les quatre jours que durera cet \u00e9v\u00e9nement international.<\/p>\n<p>Les missions actuelles d\u2019exploration de la Terre de l\u2019ESA (CryoSat, GOCE et SMOS) seront \u00e9galement mises en avant. Ces derni\u00e8res ann\u00e9es, elles ont livr\u00e9 de nouvelles informations sur la cryosph\u00e8re terrestre, la gravit\u00e9, l\u2019humidit\u00e9 des sols et la salinit\u00e9 des oc\u00e9ans.<\/p>\n<figure class=\"wp-block-image size-large\" data-width=\"6825\" data-credit=\"ESA \u2013 P.

Les r\u00e9sultats ainsi r\u00e9colt\u00e9s contribuent \u00e0 d\u00e9terminer si la couche de glace dans l\u2019oc\u00e9an Arctique \u00e0 tendance \u00e0 se fissurer ou \u00e0 fondre. En outre, la mission CryoSat permet de suivre l\u2019\u00e9volution des calottes glaciaires de l\u2019Antarctique et du Groenland.<\/p>\n<p>La mission satellite GOCE de l\u2019ESA, quant \u00e0 elle, a permis de r\u00e9colter des informations sur la gravit\u00e9 terrestre avec un niveau de pr\u00e9cision encore jamais \u00e9gal\u00e9. Ces donn\u00e9es scientifiques sont utilis\u00e9es pour \u00e9tudier les courants oc\u00e9aniques, la variation du niveau des oc\u00e9ans, l\u2019altitude de la surface terrestre et les couches inf\u00e9rieures des montagnes. GOCE a m\u00eame d\u00e9tect\u00e9 des ondes sonores provenant du gigantesque tremblement de terre qui a frapp\u00e9 le Japon le 11 mars 2011.<\/p>\n<p>Enfin, le satellite SMOS (qui \u00e9tudie l'humidit\u00e9 des sols et la salinit\u00e9 des oc\u00e9ans) nous a aid\u00e9s \u00e0 mieux comprendre le cycle de l\u2019eau. Il sert aussi \u00e0 suivre l\u2019\u00e9tendue et l\u2019\u00e9paisseur des glaces de mer de l\u2019Arctique et peut m\u00eame \u00e9tablir la vitesse des vents \u00e0 l\u2019int\u00e9rieur des ouragans.<\/p>\n<p>La prochaine mission d\u2019exploration de la Terre, Swarm, sera lanc\u00e9e en fin d\u2019ann\u00e9e. Compos\u00e9e d\u2019une constellation de trois satellites, elle devrait contribuer \u00e0 lever le voile sur l\u2019un des aspects les plus myst\u00e9rieux de notre plan\u00e8te : son champ magn\u00e9tique. Par ailleurs, le symposium Plan\u00e8te vivante comportera des pr\u00e9sentations consacr\u00e9es aux programmes de l\u2019ESA comme Copernicus, mais \u00e9galement aux nouveaux satellites Sentinelles, dont le premier sera lanc\u00e9 en 2014.<\/p>\n<p>Paxi, la mascotte du programme ESA Kids, se rendra sur place pour assister aux pr\u00e9sentations et en faire un compte-rendu en images du 9 au 11 septembre.
