  6. Anatomie martienne: après seulement deux ans de surveillance sismique, la structure interne de la planète rouge révélée

    Publishing date:

    July 25, 2021

    Avant la mission Insight de la NASA opérée par le JPL, la structure interne de Mars était encore mal connue, étudiée grâce aux images des satellites en orbite martienne et à l’analyse des météorites martiennes. Depuis début 2019 et le succès du déploiement du premier sismomètre martien, l’expérience SEIS, les scientifiques ont collecté et analysé les données sismiques d’une année martienne, soit presque deux années terrestres, qui nous donnent des indications directes sur la structure de Mars, et donc sur sa formation et son histoire.
