Scientists at the University of Leicester’s Space Research Centre are recreating the hostile environment found on Mars in their laboratory, with a device known as the Martian Environment Simulator (MES). The machine reproduces the temperature, air pressure and unbreathable atmosphere known to exist on Mars. The MES is currently being used to test equipment on the Beagle 2 lander, part of the European Space Agency’s Mars Express Spacecraft and due to arrive on Mars during Christmas 2003.
