Two More Astronaut Candidates of the remaining Ten Astronaut Candidates Fail the Astronaut Selection Process, Four of the Twelve Astronaut Candidates are gone.
The candidates must complete swim tests - swimming lengths in their flight suit and working as a team to assemble a weighted cube underwater. They then take a spin in a rotating chair and simulate manually docking a spacecraft at the ISS.
The testing steps up a gear as the remaining candidates head off to a secret facility in Sweden. They are deliberately deprived of oxygen to see if they recognise the symptoms of hypoxia and they are tested in a human centrifuge.
Leadership skills are tested in a survival challenge. The panel are joined by two experts to conduct probing interviews. The remaining candidates head off to the Kennedy Space Centre competing for a place in the final.
The finalists head to the Shuttle Landing Facility on Florida's Space Coast to consider the risks of the job. They experience weightlessness at 30,000 ft and dive down to an underwater facility.
