Explanation: Expansive Utopia Planitia on Mars is strewn with rocks and boulders in this 1976 image. Constructed from the Viking 2 lander’s color and black and white image data, the scene approximates the appearance of the high northern martian plain to the human eye. For scale, the prominent rounded rock near center is about 20 centimeters (just under 8 inches) across. Farther back on the right side of the frame the a dark angular boulder spans about 1.5 meters (5 feet). Also in view are two trenches dug by the lander’s sampler arm, the ejected protective shroud that covered the soil collector head, and one of the lander’s dust covered footpads at the lower right. On May 14, China’s Zhurong Mars rover successfully touchdown on Mars and has returned the first images of` its landing site in Utopia Planitia.

说明: 在这张摄于1976年的照片里，火星辽阔的乌托邦平原上，到处都是石块和巨岩。这片建构自海盗2号降落器彩色与黑白影像数据的照片，呈现了人类肉眼可能见到的高纬度火星平原之景色。影像中心附近的圆石，宽约20公分，可作为这张照片的量尺。此外，影像右缘的黝黑多角巨岩，宽约1.5公尺。影像中的二道沟渠，则是由降落器的取样机械所挖掘，其右侧有抛弃的土壤收集头的保护罩，而在右下角，可见到覆着沙尘的降落器脚垫。在今年的5月14日，中国的祝融号火星车成功着落火星，并回传在乌托邦平原著陆点的首张影像。
