Le prototype d’h\u00e9licopt\u00e8re Ingenuity, d\u00e9pos\u00e9 sur le sol martien sous le ch\u00e2ssis du rover Perseverance, a effectu\u00e9 son premier vol dans la fine atmosph\u00e8re martienne le lundi 19 avril. D’une masse de 1,8 kilogramme, l’h\u00e9licopt\u00e8re \u00e0 deux pales s’est \u00e9lev\u00e9 de trois m\u00e8tres au-dessus du sol et est rest\u00e9 en l\u00e9vitation une trentaine de secondes avant de se reposer.<\/p>\r\n

D’autres tests sont pr\u00e9vus dans la foul\u00e9e, chaque vol \u00e9tant suivi de deux journ\u00e9es de r\u00e9cup\u00e9ration et d’analyse des donn\u00e9es. Le rayon d’action maximal de l’h\u00e9licopt\u00e8re est estim\u00e9 \u00e0 600 m\u00e8tres environ.
Simple appareil de d\u00e9monstration technologique, Ingenuity ne poss\u00e8de qu’une cam\u00e9ra et pas d’appareil scientifique. Mais elle ouvre d’int\u00e9ressantes perspectives des reconnaissance pour de futurs mod\u00e8les am\u00e9lior\u00e9s, lors de missions ult\u00e9rieures.<\/p>\r\n
