The isolation experience, which will last a year, will be the longest of its type attempted.
Experts estimate a human mission to the Red Planet could take between one and three years.
The six-strong team will live in close quarters under the dome, without fresh air, fresh food or privacy.
Stepping outside the dome - which measures only 11 metres in diameter and is six metres tall - will require a spacesuit.
The team is made up of a French astrobiologist, a German physicist and four Americans - a pilot, an architect, a journalist and a soil scientist
