L\u2019alunisseur d\u2019Intuitive Machines, dont l\u2019exemplaire utilis\u00e9 pour cette mission a \u00e9t\u00e9 baptis\u00e9 Odysseus, emporte aussi six cargaisons priv\u00e9es. Parmi elles : des sculptures de l\u2019artiste contemporain Jeff Koons repr\u00e9sentant les phases de la Lune.<\/p>\n

Les six instruments scientifiques de la Nasa \u00e0 bord se concentrent eux sur de premi\u00e8res observations de cette r\u00e9gion encore peu explor\u00e9e. Des cam\u00e9ras plac\u00e9es sous l\u2019alunisseur devaient analyser la quantit\u00e9 de poussi\u00e8re projet\u00e9e lors de la descente, afin de la comparer aux alunissages d\u2019Apollo;<\/p>\n

l\u2019alunisseur\u00a0qui transporte notamment des instruments scientifiques de la Nasa, mesure un peu plus de quatre m\u00e8tres de haut. Il a d\u00e9coll\u00e9 la semaine derni\u00e8re de Floride et est entr\u00e9 en orbite lunaire mercredi. La descente tant redout\u00e9e a pris environ une heure<\/p>\n

Un autre instrument doit \u00e9tudier le plasma lunaire (couche de gaz charg\u00e9 en \u00e9lectricit\u00e9), et mesurera les ondes radio en provenance du Soleil et d\u2019autres plan\u00e8tes.<\/p>\n

Odysseus, qui est aliment\u00e9 en \u00e9nergie gr\u00e2ce \u00e0 ses panneaux solaires, doit normalement fonctionner durant environ sept jours \u00e0 partir du moment de son atterrissage, avant que la nuit ne s\u2019installe sur le p\u00f4le Sud lunaire.<\/p>\n","protected":false},"excerpt":{"rendered":"
