“祝融号”行驶里程突破500米，即将到达第二处沙丘
据国家航天局消息，截至7月17日23时，“祝融号”火星车行驶里程突破500米，即将到达第二处沙丘，计划对沙丘及周边环境开展详细探测。
截至目前，“祝融号”火星车在火星表面工作63个火星日，“天问一号”环绕器在轨工作359天，距离地球约3.75亿千米。当前，两器状态良好，各分系统工况正常。
7月12日，“祝融号”火星车在南向巡视探测途中，路过降落伞与背罩组合体附近，利用导航地形相机对组合体进行成像，图中可见降落伞全貌和经气动烧蚀后的完整背罩结构，背罩上的姿控发动机导流孔清晰可辨。成像时火星车距离背罩约30米，距离着陆点约350米。
China's Zhurong rover has driven for 509 meters on the surface of Mars as of 11:00 p.m. on Saturday (Beijing time), according to the China National Space Administration.
The rover is about to reach the second sand dune, where it is expected to carry out a detailed survey.
The Zhurong rover has been working on the red planet for 63 Martian days. A Martian day is roughly 40 minutes longer than a day on Earth.
The latest images sent back by the rover show its parachute and protective shell on the Martian surface.
The Tianwen-1 orbiter, which serves as a relay communication satellite, has been working in orbit for 359 days at a distance of about 375 million kilometers from Earth. The one-way communication delay is nearly 21 minutes.
The rover and the orbiter are both in good condition, with each subsystem in normal operation.
