Rubikon (2022) on Netflix

Plot summary

Hannah Wagner, a company soldier, is stationed aboard the Rubikon space station with the scientists Gavin Abbott and Dimitri Krylow. The three of them are researching an algae project meant to provide humanity with a permanent supply of oxygen and food. When they look down, Earth has disappeared under a brown, toxic fog, and every channel of contact with the ground has gone silent. Staying aboard means waiting in orbit for a signal that may never come; a return flight would put their lives at risk. They cannot tell whether they are the last survivors of humanity, or whether anyone remains below.
