The Red Planet Mars

Explanation: Mars looks pretty sharp in this backyard telescope image captured on July 23 from Hoegaarden, Belgium, planet Earth. The Red Planet’s bright south polar cap is bathed in sunlight at the top of the inverted view, while the dark feature known as Syrtis Major extends toward the right (eastern) edge. Rising around midnight for now, the Red Planet is months away from its own opposition in early October. Telescopic views will improve even more as Earth, in its faster orbit, catches up to Mars, the ruddy disk growing larger and brighter still. The martian Jezero Crater is within the Syrtis Major region. That’s the landing site for NASA’s 2020 Mars Rover Perseverance, scheduled for launch today.

说明: 在这幅7月23日摄于地球．比利时豪格登市的后院望远镜影像里，火星看起来很出采。其中，倒置在上端的明亮南极冰冠沐浴在阳光中，而名为大瑟提斯高原的暗色结构向右缘（东）伸展。目前在子夜时分升起的火星，离10月初的火星冲还有2个月。不过，随着轨道速度较快的地球追上火星，在望远镜视窗里这颗红色行星会逐渐变大和变亮。此外，位在大瑟提斯高原的耶杰罗坑，则是将在今天发射的NASA 2020毅力号火星车的著陆点。（Jezero Crater 耶杰罗坑）
