累计行驶708米！“祝融号”火星车开始穿越复杂地形地带

据国家航天局的消息，截至今天（7月30日），“祝融号”火星车已经在火星表面工作75个火星日，累计行驶708米，正在为“祝融号”火星车提供中继通信服务的天问一号环绕器在轨运行372天，两器状态良好，各系统工况正常。

上周，“祝融号”火星车行驶至巡视探测途中的一处沙丘，并对其进行了相关科学探测。据了解，火星车在完成对该处沙丘地貌科学探测后，继续向南移动，本周到达一片石块、撞击坑、沙丘分布密集的复杂地形地带。

China's Zhurong rover has started traversing a complex terrain area on Mars with rocks, impact craters, and sand dunes, according to the China National Space Administration (CNSA).

As of Friday, Zhurong has been working on the Martian surface for 75 Martian days, traveling a total of 708 meters, the CNSA said.

后续，地面飞控人员将依据每日获取的导航地形图像，完成火星车视觉定位和移动路径规划，控制火星车安全穿越这片复杂地形。路过感兴趣的科学探测目标时，火星车将利用表面成分探测仪和多光谱相机等科学载荷对其开展详细探测。在穿越途中，表面磁场探测仪、火星气象测量仪、次表层探测雷达等开机工作，获取科学数据。

A Martian day is approximately 40 minutes longer than a day on Earth.

Last week, the rover traveled to a dune and conducted scientific detection there. After completing the exploration of the topography, it will continue to move southwards and is expected to reach a complex terrain this week with rocks, impact craters, and dunes densely distributed.

The orbiter, which serves as a relay satellite communication satellite, has been working in orbit for 372 days.

The rover and the orbiter are both in good condition, with each subsystem in normal operation.

China's Tianwen-1 mission, consisting of an orbiter, a lander, and a rover, was launched on July 23, 2020. The lander carrying the rover landed in the southern part of Utopia Planitia, a vast plain on the northern hemisphere of Mars, on May 15 this year.
