Perseverance Landing Site from Mars Reconnaissance Orbiter

Explanation: Seen from orbit a day after a dramatic arrival on the martian surface, the Perseverance landing site is identified in this high-resolution view from the Mars Reconnaissance Orbiter. The orbiter’s camera image also reveals the location of the Mars 2020 mission descent stage, heat shield, and parachute and back shell that delivered Perseverance to the surface of Mars. Each annotated inset box spans 200 meters (650 feet) across the floor of Jezero Crater. Perseverance is located at the center of the pattern created by rocket exhaust as the descent stage hovered and lowered the rover to the surface. Following the sky crane maneuver, the descent stage itself flew away to crash at a safe distance from the rover, its final resting place indicated by a dark V-shaped debris pattern. Falling to the surface nearby after their separation in the landing sequence, heat shield, parachute and back shell locations are marked in the high-resolution image from Mars orbit.

说明: 这幅来自火星探勘号轨道船的高解析影像,呈现在毅力号着陆火星表面之后一天,毅力号着陆点附近的景观。在这张探勘号轨道船的相机影像里,可认出火星2020任务布署毅力号到火星表面时,所使用的降落级、热遮罩、与及降落伞和外罩散落的位置。其中,每个加注的嵌图,涵盖耶杰罗坑底200公尺宽的区域。毅力号的位置,是在降落级悬浮及垂降这艘火星车到表面时,所造成的二片火箭喷气痕的中间。紧接在天空起动机操作之后,降落级立即飞离,最后坠毁分裂的碎片撤出形似字母V的暗色区。此外,在着陆操作序列中分离的热遮罩与降落伞和外罩,分别着陆在这张火星轨道影像右缘和左缘附近。
