毅力号造访耶泽罗坑的河流三角洲
Perseverance in Jezero Crater’s Delta

Explanation: The Perseverance rover’s Mastcam-Z captured images to create this mosaic on August 4, 2022. The car-sized robot was continuing its exploration of the fan-shaped delta of a river that, billions of years ago, flowed into Jezero Crater on Mars. Sedimentary rocks preserved in Jezero’s delta are considered one of the best places on Mars to search for potential signs of ancient microbial life and sites recently sampled by the rover, dubbed Wildcat Ridge and Skinner Ridge, are at lower left and upper right in the frame. The samples taken from these areas were sealed inside ultra-clean sample tubes, ultimately intended for return to Earth by future missions. Starting with the Pathfinder Mission and Mars Global Surveyor in 1997, the last 25 years of a continuous robotic exploration of the Red Planet has included orbiters, landers, rovers, and a helicopter from planet Earth.

说明: 毅力号火星车的桅杆相机-Z，于2022年8月4日拍下了这幅拼接影像。这部汽车大小的火星车，持续在探索数十亿年前汇入火星耶泽罗坑的扇形河流三角洲。留存在于耶泽罗三角洲的沉积岩，被认是火星上寻找远古微生物形态生命迹证的最佳可能地点之一，而火星车最近进行采样的野猫岭和斯金纳岭，就位于这片视野的左下角和右上角。从这些区域采集的样本，将封存在超洁净的样本管里，希望未来由后续的火星任务送回地球。在过去25年里，从1997年的探路者号和火星全球量测号任务开始，持续有无人操控的火星器械探索这颗红色行星，其中包括轨道船、着陆器、火星车及一部来自地球的直升机。
