This is a greenhouse that can be used inside the space shuttle and the HUB while you are staying on another planet. This greenhouse has two portals; each portal has its own specific job. The orange cylindrical portal allows for oxygen flow while the hexagonal portal allows for carbon dioxide and other excess gas flow. Inside the airtight greenhouse you can grow small amounts of plants that will allow for testing of soils to see if they have the nutrients for plants to grow. The purpose of this greenhouse is to allow for plant growth and color to be added to the dull colored environment. But, the greenhouse will also be growing plants that an astronaut can eat and would not be used to eating. This will allow for a better diet for astronauts and give them an opportunity to change their meals they are eating every once and awhile.
