[1]2004年1月，火星探测漫游车使命将在两个不同的着陆点着陆两个漫游车，显示过去液态水活动的可能证据。航天器的设计是基于火星探路者配置巡航和进入，下降和着陆。每个相同的漫游者都配备了两个遥感仪器的科学有效载荷，可以从桅杆的顶部观察周围的地形，一个机械臂可以在选定的岩石和土壤样本上放置三个仪器和岩石磨损工具，以及几个板载磁铁和校准目标。对科学调查有用的工程传感器和组件包括立体导航摄像机、前后立体危险摄像机、车轮电机、车轮电机电流和电压、用于挖掘的车轮本身、陀螺仪、加速度计和参考太阳能电池读数。使命操作将允许在每个火星日或火星日的基础上对火星车进行指挥。在90溶胶的使命寿命，漫游者预计将驾驶数百米，同时进行实地地质调查，勘探和大气特征。这些数据产品将作为综合批量档案提交给行星数据系统。
[1] In January 2004 the Mars Exploration Rover mission will land two rovers at two different landing sites that show possible evidence for past liquid-water activity. The spacecraft design is based on the Mars Pathfinder configuration for cruise and entry, descent, and landing. Each of the identical rovers is equipped with a science payload of two remote-sensing instruments that will view the surrounding terrain from the top of a mast, a robotic arm that can place three instruments and a rock abrasion tool on selected rock and soil samples, and several onboard magnets and calibration targets. Engineering sensors and components useful for science investigations include stereo navigation cameras, stereo hazard cameras in front and rear, wheel motors, wheel motor current and voltage, the wheels themselves for digging, gyros, accelerometers, and reference solar cell readings. Mission operations will allow commanding of the rover each Martian day, or sol, on the basis of the previous sol's data. Over a 90-sol mission lifetime, the rovers are expected to drive hundreds of meters while carrying out field geology investigations, exploration, and atmospheric characterization. The data products will be delivered to the Planetary Data System as integrated batch archives.
