Twighlight zone (new ones) Episode 6 - six degrees of freedom

I figured it out this morning. This is the New Twilight Zone episode Six Degrees of Freedom (2019).

“Six Degrees of Freedom” tells the story of a group of astronauts who have been chosen to lead a mission to Mars. Moments before their launch, though, they receive a radio transmission which suggests that North Korea has just launched nuclear missiles. Now facing the unenviable position of living on a planet devastated by nuclear war, the crew make the difficult decision to head to Mars as planned and deal with whatever may come next.
