High-Level Project Summary
NNESS is able to withstand the extreme conditions on Venus, achieved by its layering system, first Graphene + NaOH layer neutralizes CO2 corrosion and the sulfuric acid rain effect, second Non-Newtonian Fluid layer and third Titanium layer reduces the extreme pressures and limits the ambient temperature flow to what is required for the Sodium-Sulfur Battery located in the center of the system.

Detailed Project Description
The project consists in the proposal of Energy Storage System which provides the power and characteristics a rover requires to survive at the Venus atmosphere. It works as thermoelectric battery for which we should solve the problems the environment presents. The benefits the project has is that we proposed an idea to start to understand how we can give a solution about a problem that is not resolved yet. Some tools helped us to develop our project were designs software such as SolidWorks, reliable information sources like NASA websites and scientific articles where we could extract the most relevant data.
Space Agency Data
For this challenge, the team looked up for all data available, we gathered data from missions like venera, to have an idea of the difficulties from past mission, we used NASA open data sources for temperature, pressure and atmospheric composition, such as the JPL info from their material investigations. Data was gathered from Universities such as de MIT, UCLA & Tokio University for battery components that could be used on the harsh Venusian environment as well as some public information from companies to get the material costs and mass.
Hackathon Journey
The experience was comforting since we were able to mix different careers to achieve a complete team where the skills, knowledge and aptitudes complete each other to solve the challenge. We chose “exploring Venus together” considering the similar conditions of this planet with ours. We also wanted to challenge our creativity by designing a battery able to withstand the adverse conditions presented in the planet, such as the high corrosion and pressure. Teamwork was key to solve this challenge, and brainstorming was enriching in order to focus and arrange the missing pieces of the puzzle.
Acknowledgments to our teachers Mustri and Julio for inspiring us and motivating during the process.
