Among the devices on board the rover are 23 cameras, two "ears" that will allow it to listen to Martian winds, and lasers used for chemical analysis.
漫游车上的设备包括23个摄像头、两只能听见火星风的“耳朵”,以及用于化学分析的激光器。
Approximately the size of a car, the rover is equipped with six wheels like its predecessor Curiosity, allowing it to traverse rocky terrain.
漫游车的尺寸和汽车差不多,和其前辈“好奇号”一样装备了六个轮子,这样就能在岩石地带上行进。
Speed is not a priority for the vehicle, which only has to cover around 200 yards (180 metres) per Martian day - approximately the same as a day on Earth.
漫游车的速度不是最重要的,它每个火星日(约等于一个地球日)只能行进大约200码(180米)。
Fuelled by a miniature nuclear reactor, Mars 2020 has seven-foot-long (two metre) articulated arms and a drill to crack open rock samples in locations scientists identify as potentially suitable for life.
火星2020年漫游车的燃料由一个小型核反应堆提供,它拥有7英尺长(2米)的铰接手臂以及一个钻头。钻头可以钻开科学家们认为可能适合生命生存的地点的岩石样本。
