Before we started working, we assumed a few things:

·        We can bring farming seeds from Earth.

·        We can bring soil from Earth/ the Martian soil is suitable for farming.

·        Optional: we can bring Eisenia Fatida (a kind of red worm used for making compost) for a more effective fertilizer.

·        The habitat is built in such a way that it is shielded from Martian radiation.

·         It is possible to grow plants in the habitat using photosynthesis via led lights.

·        We have led lights capable of providing enough light for the plants (from shipwrecks).

·        It is possible to move the Eco Table into the habitat.

·        We have enough water for watering the plants.

·        We can stick lights, cables, and batteries on the bottom side of the tabletop before the concrete dries up.

·        We can move the tabletop and assemble it.

Physical features:

The Eco Table is mostly concrete, with led lights attached to it at the bottom side of the tabletop. It has 3 types of parts, and it is easy to assemble. The Eco table has a few parts:

·        Lid - diameter of 130mm, the height of 70mm. Has a handle for an easy pick. Made out of ABS for weight purposes. Mass is 0.618107kg. Total of 7 pieces. The central one is used for covering waste disposal and preventing bad smells. The other 6 are covering the ring of dirt and would be opened for watering purposes.

·        Table top diameter of 1800mm, the height of 50mm. Made out of concrete. Mass is approximately 288.24kg, which feels like 109.53kg on mars.

· Hexagon-shaped body- side is 500mm. Height of 1400mm. Mass is approximately 365.04kg, which feels like 138.71kg on mars. Made out of concrete. includes:

o  Disposal system which is also a “brewery” for compost. It has holes for better surface area touching the soil. The side length is 228.868mm.

o  The space inside the body holding the soil.

o  Pockets that work as pots for the plants. Height is 165.78mm.

·        Optional: due to lack of time, we failed to design an optimal piping system. The pipe would be spiral and would have holes in it for

 How to operate?

To assemble it, you put the tabletop on the body. You put the lids in their place. You fill up the space outside the composter for dirt. You plant seeds in the pockets and water it from the top of the table when the lids are open. As for the compost, after you finish your meal, you throw all of your leftovers and waste into the waste disposal. The waste piles up and slowly transform into a fertilizer. If possible, we plan to mix worms inside for better and faster compost.

The data from the Veggie Project (https://www.nasa.gov/sites/default/files/atoms/files/veggie_fact_sheet_508.pdf) inspired us and gave us the idea of growing vegetables in space and the Worms In Space project (https://www.nasa.gov/audience/foreducators/9-12/features/F_Worms_in_Space.html) data gave us the idea that we can add worms to out compost. We relied a lot on the data from the Veggie project. the project taught us that it is possible to grow plants in the extreme conditions of space so we assume that we can grow plants on mars in less extreme conditions 

When we first heard about the 3d printing challenge we were really excited, a challenge that includes many of our interests- 3d design, engineering, space, and physics. The challenge required us to think outside the box, working with the few limiting rules we got and hopefully, succeeding in the challenge!

We spent the days before the hackathon brainstorming ideas, learning about mars and the Martian environment, watching movies to be inspired, and basically every bit of time we had we spent thinking about the challenge. The day before the hackathon we watched the movie The Martian and it gave us a lot of inspiration and a new point of view about the challenge. Our approach for the challenge was- instead of making a few simple tools, that are easy to make and easy to think about, we made one product that is quite simple but creative. Although a product with all these qualities is challenging to make, we brainstormed solutions for every problem that came up and managed by teamwork to overcome the problems. We compromised for bigger things that are easy to assemble, rather than a lot of light but complicated parts. We would like to thank the MonkeyTech team for hosting the hackathon. Ohad, one of the mentors, helped us a lot by shedding light on different problems in the product. We figured together to structure and print problems and difficulties. It was great fun and we learned a lot from the mentors, the other teams, and the process itself.
