‘Cosmonauts’ ready for Mars test BBC

A Belgian, two Frenchmen and a Colombian-Italian have agreed to be locked away in steel containers for 18 months to simulate a mission to Mars.
Their self-imposed exile will test the physical and mental requirements of ultra-long duration spaceflight.
The Europeans will join a predominantly Russian crew for the Mars500 project, which is due to start in May.
All the food and water needed for the “journey” will have to be loaded into the “spacecraft” before “departure”.
There will even be a simulated landing.
After about 250 days, the crew will be split in two, and three “cosmonauts” will move into a separate container to walk on the “surface of the Red Planet” wearing modified Russian Orlan spacesuits.
