The Nasa astronauts on a mythical mission to Mars moon

Nasa is finding out how people cope with the demands of long space missions at its Human Exploration Research Analog (Hera).

For 45 days a crew of four people live in a habitat which simulates a mission to Phobos, a moon that orbits the planet Mars.
