The Garposer is a garden box with a rolling lid and a decomposer. It is meant to be used on mars to enhance the duration of life for exploration. Plants and food will improve your mood in space. A decomposer is helpful to recycle extra scraps of food left over from meals and other organic material to be transformed into healthy soil for growing plants to survive. The plants give off oxygen to keep the air healthy and you can eat fresh, delicious food. The Garposer would be most useful if printed out of glass or clear rock to let light through and keep water from leaking through. Glass filament can be produced on mars from the many sand dunes and light from the sun without having to carry materials from earth. Have fun growing!
