For some time now NASA has been developing projects that would create renewable food sources for its future crew on Mars. Some of the projects include aquaponic systems and greenhouses. One of the greenhouse modules proposed of the next Martian rover is the Mars Plant Experiment (MPX), a tiny entirely self-contained greenhouse.
High radiation levels and low gravity on Mars make the planet inadequate for growing plants. The MPX greenhouse would employ a CubeSat box containing enough Earth air for 15 days and about 200 seeds of Arabidopsis, a small flowering plant often used in scientific research. The experiment would provide an opportunity to test the Mars environment and investigate how Earth life adapts to hostile conditions.
The MPX greenhouse would be brought to Mars as part of the mission scheduled for 2020. It is one of 58 proposed experiments for the vehicle.
