L\u2019atterrissage aurait d\u00e9sormais lieu en novembre 2018.<\/p>\n

C\u2019est un soulagement pour les ing\u00e9nieurs de cette mission qui craignaient son annulation pure et simple. Au budget de 675 millions de dollars, les agences spatiales ont d\u00e9cid\u00e9 d\u2019accorder les 154 millions suppl\u00e9mentaires pour r\u00e9parer la partie fautive et les frais de stockage et d\u2019entretien de la sonde sur deux ans. Si les pi\u00e8ces du sismom\u00e8tre restent celles fabriqu\u00e9es par le CNES fran\u00e7ais, leur int\u00e9gration sera d\u00e9sormais la responsabilit\u00e9 du centre JPL de la NASA.<\/p>\n

Rappelons que la sonde InSight doit se poser dans Elysium Planitia et son sismom\u00e8tre mesurer l\u2019activit\u00e9 sismique interne de Mars et les impacts de m\u00e9t\u00e9orites, alors qu\u2019un thermom\u00e8tre \u00e0 couple allemand, qui s\u2019enfoncera dans le sol jusqu\u2019\u00e0 5\u00a0m de profondeur, mesurera le flux thermique en provenance de l\u2019int\u00e9rieur du globe.<\/p>\n","protected":false},"excerpt":{"rendered":"
