Le 21 mars, sa coque protectrice a \u00e9t\u00e9 \u00e9ject\u00e9e et le rover s’est mis en route pour d\u00e9poser l’h\u00e9licopt\u00e8re sur son aire de d\u00e9collage qui mesure environ dix m\u00e8tres sur dix. Apr\u00e8s l’avoir d\u00e9ploy\u00e9 et charg\u00e9 ses batteries, Perseverance reculera de cinq \u00e0 six m\u00e8tres.<\/p>\r\n

Le premier vol est programm\u00e9 le 8 avril\u00a0: apr\u00e8s une mise en rotation de son rotor \u00e0 2500 rotations\/minute, l’appareil devrait s’\u00e9lever d’environ trois m\u00e8tres, faire du sur place et un petit virage avant de se reposer au bout d’une trentaine de secondes.<\/p>\r\n

Au cours du mois qui suivra, plusieurs autres tests auront lieu, sur une distance d’une cinquantaine de m\u00e8tres et des dur\u00e9es de vol d’une minute et demie. Puis, apr\u00e8s \u00e9puisement des batteries, ce premier test technologique d’un h\u00e9licopt\u00e8re sur Mars sera achev\u00e9.
