C\u2019est en 2025 qu\u2019il sera d\u00e9cid\u00e9 si le nouveau t\u00e9lescope Einstein, un observatoire europ\u00e9en de pointe des ondes gravitationnelles, sera install\u00e9 dans la r\u00e9gion des Trois Fronti\u00e8res entre la Belgique, l\u2019Allemagne et les Pays-Bas (voir ici<\/a> l\u2019article consacr\u00e9 au t\u00e9lescope par EOS). Cette r\u00e9gion est un endroit id\u00e9al : ses atouts sont le calme, la stabilit\u00e9 du sol et un important maillage de centres d\u2019expertise et d\u2019entreprises de haute technologie.<\/p>\n

Au travers d\u2019un partenariat, nous avons soutenu l\u2019installation \u00e0 Plombi\u00e8res de deux stations IGR (Integrated Geodetic Reference). L\u2019installation a \u00e9t\u00e9 financ\u00e9e par l\u2019Agence spatiale europ\u00e9enne (ESA). Divers partenaires ont collabor\u00e9 \u00e0 l\u2019installation et assurent \u00e0 pr\u00e9sent le suivi : l\u2019IGN, le Centre Spatial de Li\u00e8ge, l\u2019Universit\u00e9 de Li\u00e8ge, l\u2019Universit\u00e9 technologique de Delft, et le Service g\u00e9ologique de Belgique. Depuis, l\u2019IGN traite chaque jour les donn\u00e9es GNSS afin de d\u00e9celer et de quantifier d\u2019\u00e9ventuels mouvements du sol.<\/p>\n

Le t\u00e9lescope Einstein pourra d\u00e9tecter jusqu\u2019\u00e0 mille fois plus de sources d\u2019ondes gravitationnelles que tous ses pr\u00e9d\u00e9cesseurs. Un d\u00e9fi de niveau mondial, avec de grandes opportunit\u00e9s pour la science et la technologie.<\/p>\n
