La corrosion affecte les modules habitables du Lunar Gateway

Français

L'administrateur de la NASA, Jared Isaacman, a confirmé que les deux modules habitables livrés pour la station spatiale Lunar Gateway, HALO et I-HAB, présentent des problèmes de corrosion. Cette révélation a été faite lors d'un témoignage devant le Congrès et s'ajoute aux raisons justifiant la suspension du programme afin de donner la priorité aux missions sur la surface lunaire. Northrop Grumman et l'Agence spatiale européenne traitent actuellement ce problème.

Pendant une décennie, la NASA a promu le Lunar Gateway comme une station en orbite lunaire destinée à tester l'habitation dans l'espace lointain et à soutenir l'exploration lunaire. Les plans de lancement ont été décalés de 2022 à 2024 pour le module HALO et l'unité de puissance, le module I-HAB étant prévu pour 2026. En mars, Isaacman a annoncé une pause concernant le Gateway afin de concentrer les ressources sur la surface de la Lune, dans un contexte de concurrence avec les ambitions lunaires de la Chine et de coûts en forte augmentation.
