There’s no backing out now for the remaining contestants and this week, the competition really steps up.
The contestants head to Sweden where they are deliberately deprived of oxygen to see if they can recognise the signs of hypoxia, critical for an astronaut on a spacewalk. Their ability to withstand the strong g-forces of space travel are put to the test, and finally, their communication skills are put to the test as well as their ability to impress Chris and the panel with their specialist space knowledge.
