[:ja]ソユーズが地球帰還のために国際宇宙ステーションISSから離脱してする瞬間です!
地球がかなり大きく映っていますが、よく宇宙飛行士が言うように、ISSの高度400kmは地球の直径13,000kmの3%に過ぎず、地球は窓の半分以上を占めるので思った以上に軌道が低いと感じ、大気・海洋汚染が如実にわかるそうです。

[Earthview Wonders] No.12: Soyuz’ return to Earth
The moment of Soyuz’ undocking from ISS for returning to Earth!
Earth occupies most of the screen and this is no surprise, as astronauts say, 400km orbit accounts for only 3% of Earth’s 13,000km diameter, and so they can clearly see air and ocean pollution as well.
