记者从国家航天局获悉，根据遥测数据判断，5月22日10时40分，“祝融号”火星车已安全驶离着陆平台，到达火星表面，开始巡视探测。 天问一号任务的科学目标是研究火星形貌与地质构造特征、火星表面土壤特征与水冰分布、火星表面物质组成、火星大气电离层及表面气候与环境特征、火星物理场与内部结构等。 探测器自2020年7月23日发射以来，在地火转移飞行、环火轨道运行期间，环绕器配置的中分辨率相机、高分辨率相机、矿物光谱分析仪、磁强计等7台科学载荷陆续开机探测，获取科学数据。火面工作期间，火星车将按计划开展巡视区环境感知、火面移动和科学探测，通过配置的地形相机、多光谱相机、次表层探测雷达、表面成分探测仪等6台载荷，对巡视区开展详细探测。同时，环绕器将运行在中继轨道，为火星车巡视探测提供稳定的中继通信，兼顾开展环绕探测。 火星车驶上火星表面模拟图像 China's Mars rover Zhurong rolled down the ramp to begin its mobile mission on the Red Planet at 10:40 a.m. Beijing Time (0240 GMT) on Saturday, according to the China National Space Administration. The rover will travel on the Mars surface and gather information of its surroundings, carry out scientific explorations with six payloads, including a configured terrain camera, multispectral camera, subsurface detection radar, surface composition detector, and more. The rover's exploration is a part of the Tianwen mission, which is being carried out to study the various characteristics of Mars, including its morphology and geological structure, soil features, water-ice distribution, composition, ionosphere, climate, atmosphere, and the physical and internal structure. At the same time, the orbiter of the Tianwen probe will operate in a relay orbit, providing stable relay communication for Zhurong. Zhurong came about one week after the lander and rover of the probe touched down on Utopia Planitia, vast terrain in the planet's northern hemisphere, on May 15.
