Nasa’s Artemis astronaut feared they would never get home as they flew around the Moon | The Independent

The mission had a specific point at which the spacecraft was to get to (its apogee) and then it would fire the rockets to return. 

But as it rounded the moon, the indicator of how many miles from earth “ticked past” the number they were using. 

And that caused a mild panic among the astronauts. Reed discussed what he was thinking as he saw the ship continue on into what we would consider deep space.
