This project is solving the Growing Food for a Martian Table challenge. Description
Making a self-deployable greenhouse which will satisfy the needs for the humans (the astronauts) who are going to temporary live on Mars.
This project has a big influence on the outgoing missions on Mars. It produces fresh food like fruits and vegetables with the necessary nutrients which are needed for the astronauts but it also produces oxygen which is very important for survival. The mission will take place in the period of 2 years after which the astronauts will arrive on Mars. To be exact on every 6 months we plan to send one capsule. In total there will be four deployed green houses and the fifth will come with the crew. The green houses will be deployed on the equator because the conditions for survival for both the green houses and the crew are greater due to better temperature. In addition it is easier to land on the equator, than on the north or south pole.
The green houses are in a hexagon shape where they can merge with one another to form a honeycomb like shape. - The first four green houses will be packed into their socket which is the size of 1.5 meters until they leave the earth atmosphere after witch they will start with their opening and operation. - The first green house will be designated to produce 80% oxygen and 20% food, the second 60% oxygen and 40% food, the third 30% oxygen and 70% food and the fourth will be designated to produce only food for the crew. - The fifth green house will be deployed by the crew. This one will serve for transplanting the plants that are already grown in the previous gardens and increase storage capacity for the necessary resources. But after the arrival of the fifth garden the expansion of the "honeycomb" will not stop and can be increased depending on the needs of the people who inhabited Mars.
- The green house is 5 meters wide and 5 meter high.
- We use scalar spiral structure for the platforms where the plants are being grown. Every platform is 10 centimeters away from the next.
- for watering the plants we use AEROPONIC system. In the inside, the platforms consist of spray like watering system which distributes hydro-atomized droplets which are easily distributed on the roots and we save water. The plant are placed into cylinder shaped containers from witch the roots float freely in the air.
- The robotic arm has and RGB camera witch detects when a plant is ready for harvesting, and it is also used for planting. The robotic arm moves in spiral motion when it's going up, and goes straight down for energy conservation reasons.
- the plants are illuminated with UV LED.
- The isolation from radiation and the Mars atmosphere is accomplished with five layers of Graphene which reaches 97% protection. We use Graphene because is cheaper from the other materials that protect from radiation and it's very thin (0.345nm) and elastic. The liquid crystal is used when the garden needs to be darkened and the inside temperature to be contained, which is accomplished when it is under electricity. Superhydrophobic nano material is used for water vapor (droplets) to streamline the pipe where nothing will remain on the walls of the graphene. The tubes that are made of carbon fiber are used to direct water collected from the evaporation of water to the tank. We use carbon fiber because it is very stretchy material. And in the last layer we use another layer of graphene for total absorption of water vapor to the area where the U-shaped tube of carbon fiber is placed.
The plant storage is placed into a cooler which is filled only with pure nitrogen to maintain the food fresh.
