Earth Flyby of BepiColombo

Explanation: What it would look like to approach planet Earth? Such an event was recorded visually in great detail by ESA’s and JAXA’s robotic BepiColombo spacecraft last month as it swung back past Earth on its journey in to the planet Mercury. Earth can be seen rotating on approach as it comes out from behind the spacecraft’s high-gain antenna in this nearly 10-hour time-lapse video. The Earth is so bright that no background stars are visible. Launched in 2018, the robotic BepiColombo used the gravity of Earth to adjust its course, the first of nine planetary flybys over the next seven years — but the only one involving Earth. Scheduled to enter orbit in 2025, BepiColombo will take images and data of the surface and magnetic field of Mercury in an effort to better understand the early evolution of our Solar System and its innermost planet.

说明:航向地球会看到什么?在上个月,欧洲航天局和日本宇航研究开发机构(JAXA)的贝比科隆博号太空船,在前往水星的旅途中旋绕过地球,并拍下这种事件的高清晰影像。在这部拍摄时间将近10小时的缩时影片里,当地球从太空船的高增益天线后方露出来后,而其转动的身影清楚可辨。在影像里,由于地球过于明亮,因此见不到任何背景恒星。 发射于2018年的贝比科隆博号太空船,运用地球的重力来调整它的航向,这是7年9次行星飞越的首次,也是地球参与的唯一一次。将在2025年入轨水星的贝比科隆博号,预定要拍摄水星表面的影像,量测水星的磁场资料,以厘清水星和我们太阳系形成初期的演化。(BepiColombo贝比科隆博号)
