Mai Dong reached out her hand and drew a curve on the glass windows that had frosted up. It overlapped with the Martian equator in the distance.
The United Space Station's altitude was constantly dropping, but Mai Dong didn't know the exact number of kilometers herself. However, she could somehow sense that Mars was getting nearer. She could see more of the details of the Martian surface, but perhaps that was just a mistake on her part. At that height, Mars was forever a dark orange curve that she could see but not touch.
However, because she couldn't fully place this gigantic curve within her sights, she subconsciously felt that her altitude had indeed decreased significantly. With the horizon's curvature becoming smaller, the gigantic sphere slowly turned into a flat plane before her very eyes.
The girl drew a tiny person on the window before adding a smiley face to it.
