Tabletop RPG about space exploration I was wondering if there is a game that might grasp the feel of movies like Interstellar and The Martian. 
I like the idea of exploration and survival that is the core of the characters in these movies. I would love it if it was PbtA but if not I'm sure I could figure it out. 
The main issue I could see is where new characters would come from without breaking the isolation of the setting.
