Mars offers no reward for survival and no meaning for suffering. It allows only one thing: completion.

The first mission to Mars has landed, only to find out, it has lost all communication with ground control and Earth. Someone or something has destroyed two satellites in low Earth orbit, and the astronauts in the International Space Station have to make an emergency maneuver to try to protect themselves from the rapidly expanding debris fields that could destroy the station and kill everyone onboard. In what is called the Kessler Effect, satellites are being destroyed due to the cascading effect of debris from continuous ongoing debris strikes compounded by the existing space junk.

Gaia Station is a bit different from most stations. For one thing, it is divided into countries and, where you have countries, you can have a war. Of course, a war on a space station isn’t quite the conflict you would imagine. This particular one got started over a rude remark about somebody’s hat. Given that it started for such a comical reason, it seems entirely reasonable that the crew of the Celeste might be able to help stop it. The fact that they had to enlist the help of scheming hotel keeper, a chef, and a dominatrix seems entirely appropriate under the circumstances.
