EARTH-MARS CYCLER SYSTEM [EMCS] is a space transportation system designed to optimize travel time between Earth and Mars and to 

provide living space and protection for the time of transit. Two identical space stations are put into carefully timed orbits, 

that cyclically come into vicinity of destination planets. EMCS modular design allows for the creation of diverse spaces, 

including crew quarters, laboratories, workshops.

Rotating element of the station provides 0.38G of centrifugal gravity in two attached modules, which keeps crew in good health and strength, ready for Mars.

Project was co-designed with Maciej Rebisz.
