Une fois leur mission termin\u00e9e, ils laissent une tra\u00een\u00e9e de d\u00e9bris derri\u00e8re eux, ce qui met en danger les satellites en exercice et contraint r\u00e9guli\u00e8rement la station spatiale internationale \u00e0 des man\u0153uvres d\u2019\u00e9vitement.<\/p>\n<p>Un projet europ\u00e9en pour lutter contre les d\u00e9chets spatiaux est entr\u00e9 dans sa phase op\u00e9rationnelle le 2 avril 2018, avec la mise en orbite d\u2019un satellite \u00ab chasseur \u00bb, appel\u00e9 RemoveDEBRIS, depuis la base de Cap Canaveral. Lanc\u00e9 dans le cadre du programme FP7, ce projet rassemble dix partenaires, dont le <a href=\"https:\/\/www.csem.ch\/home\" target=\"_blank\" rel=\"noopener\">CSEM<\/a>.<\/p>\n<p>L&rsquo;institut de recherche bas\u00e9 \u00e0 Neuch\u00e2tel est connu dans la communaut\u00e9 spatiale pour fournir des technologies de pointe et une instrumentation scientifique tr\u00e8s pr\u00e9cise dans le domaine des satellites et des t\u00e9lescopes.

Pesant moins de deux kilos et mesurant 10 x 10 x 15 centim\u00e8tres, cet appareil \u00e9claire l&rsquo;objet \u00e0 attraper, puis mesure avec pr\u00e9cision la distance des d\u00e9bris.
