The scriptwriter probably doesn't know about redundent backup Aside from the astronauts against each other, the spacecraft is clearly not like what a co-op product from NASA and CNSA and Roscosmos and ESA and that Indian space agency should be. Right in episode 2, "oh no, one of the three solar panels can't be in place, we all gonna die", and they go EVA without umbilical cable or jet pack? Then in episode 6, their water filter jammed, and the backup system got only half of the capacity? How the hell they just keep run into technical issues with no backup options, which would be something that NASA would do everything to avoid?
