En 1996, l\u2019astrophysicien et c\u00e9l\u00e8bre passeur de sciences Carl Sagan milite activement aupr\u00e8s de la Nasa pour que l\u2019agence installe un micro sur son prochain atterrisseur martien. \u00ab\u00a0M\u00eame si cette premi\u00e8re exp\u00e9rience ne permet d\u2019enregistrer que quelques minutes de sons martiens, l\u2019int\u00e9r\u00eat du public sera consid\u00e9rable et cela offrira une v\u00e9ritable occasion d\u2019exploration scientifique\u00a0\u00bb, argumentait-il dans une p\u00e9tition. Il sera ainsi \u00e0 l\u2019origine du premier microphone martien. Malheureusement, le Mars Polar Lander qui l\u2019emportait s\u2019est crash\u00e9 sur la plan\u00e8te en 1999 et il faudra finalement\u00a0attendre 2021 pour qu\u2019un premier micro fonctionnel soit d\u00e9ploy\u00e9 sur Mars<\/a>, \u00e0 bord du rover Perseverance. Et cocorico, c\u2019est \u00e0 une \u00e9quipe fran\u00e7aise que l\u2019on doit cette r\u00e9alisation, int\u00e9gr\u00e9e\u00a0\u00e0 l\u2019instrument SuperCam, d\u00e9velopp\u00e9 \u00e0 l\u2019Irap<\/a>\u00a0(Institut de recherche en astrophysique et plan\u00e9tologie), \u00e0 Toulouse, qui constitue la \u00ab\u00a0t\u00eate\u00a0\u00bb iconique du laboratoire roulant de la Nasa, et lui conf\u00e8re ce petit look<\/p>\n
