High-Level Project Summary
Our project idea is to consider wastewater &CO2-rich cabin air as a resource for plant cultivation rather than wastes. the main system we are proposing is depending on utilize water and air as a medium in plant growth systems. Water or air solution that’s rich in nutrients is used as the main medium in the Hydroponic or Airponic system, At first, the system gets the water from an external source, then the air will be produced by hydrolysis of the used water. After that, plant growth systems can be used to recycle exhaled CO2 producing O2 through the photosynthetic process and to purify wastewater through its uptake and transpiration of water vapor that can be condensed in pure water

Detailed Project Description
Our project mainly depends on hybrid-controlled Environment agriculture (CEA) which is a combination of a Hydroponic system and an Aeroponic system. Firstly, the hydroponic system will allow minute control over environmental conditions like temperature and pH balance and maximized exposure to nutrients and water then the used water is going through a hydrolysis process. A partial amount of the produced oxygen gas will be utilized in the next Aeroponics system which is a process of growing plants in an air or mist environment. For the next step, the stored methane gas in the space shuttle will be introduced to the oxygenated gas produced by plants which are going to burn the following reaction CH₄[gas] + 2O₂[gas] → CO₂[gas] + 2H₂O[steam] + 891kJ. The third step is to condense the produced water from the previous reaction then reuse it in the hydroponic system, furthermore, the carbon dioxide will be utilized to react with the hydrogen gas produced by the hydrolysis process. This cycle is perfectly implemented in the spacecraft during travel time. Moreover, the oxygen-methane gas will not be required on Mars owing to that Mars’ atmosphere is full of carbon dioxide. In addition, the storage will be done at the spacecraft by using a freeze-drying mechanism that works by freezing the material, then reducing the pressure and adding heat to allow the frozen water in the material to change directly to a vapor (sublimate ). Due to the climate temperature on Mars food will be stored in aluminum foil as it has high refraction power for all ultraviolet rays.

Hackathon Journey
The Nasa space app is really inspiring competition that lets us be rounded people, not a book worn. We learned how to work under stress and time management .. we were happy for working together but we found difficulties with online sessions only. The main inspiration for us is our goal to land on Mars one day and to have an effective impact on the surrounding environment. We divided our tasks, long time search for the applicable ideas, and start to analyze these data. We search again about challenges and recent solutions and analysis this. After that, we make meetings to make deep discussions. Then we take action.
