Perseverance Takes a Spin

Explanation: After arriving at Jezero Crater on Mars, Perseverance went for a spin on March 4. This sharp image from the car-sized rover’s Navcam shows tracks left by its six wheels in the martian soil. In preparation for operations on the surface of the Red Planet, its first drive lasted about 33 minutes. On a short and successful test drive Perseverance moved forward 4 meters, made a 150 degree turn in place, backed up for 2.5 meters, and now occupies a different parking space at its newly christened Octavia E. Butler Landing location. Though the total travel distance of the rover’s first outing was about 6.5 meters (21 feet), regular commutes of 200 meters or more can be expected in the future.

说明: 在抵达火星耶杰罗坑之后,毅力号于3月4日去兜风试车。这幅来自这部火星车导航相机的清晰影像,记录了它的车轮印在星土壤上的轮痕。这个为在火星表面操作任务热身的试车,历时约33分钟。在此次简短但成功的试车里,毅力号往前移4公尺,然后转150度,接着后退2.5公尺,因此在刚命名的巴特勒着陆区里,已移到不同的停车位置。虽然毅立号火星车此次试车只移动6.5公尺,不过在未来,它行驶超过200公尺会是常态。
