London, March 29 : Six volunteers will be locked up in small steel tins off a parking lot in Moscow for 105 days, as scientists simulate a space rocket ride to Mars.

The cramped metal capsules will be connected by cables and corrugated metal pipes in a hanger at the back of the Institute of Medical and Biological Problems (IMBP) in the Russian capital on Tuesday.

The objective behind this experiment is to recreate as closely as possible the atmosphere of a spacecraft racing through the solar system, bombarded by cosmic radiation.
