High-Level Project Summary
The Rover that we developed has the objective of staying 60 days on Venus and for that the Rover will have in its composition a first layer of LI900 where it will resist the temperature of 500ºC and the impacts, in the second layer we will have the glass wool to insulate the heat and do not let the components melt, in the third layer will have brass plus special aluminum as an additional protection. For the movement of the Rover, a mat was created with space ceramics, which will be moved by an electric motor and the savonian turbine. of energy we will have a modified solar panel, having as components Alontm, VAT600, Arsenio, Galio and Aerogel for better protection against the temperature.

Detailed Project Description
Our project consists of creating a rover, whose objective is to last at least 60 days on Venus, breaking all previous barriers. For this, we focus on developing a resistant and self-preventive system, reducing the risk of failure as much as possible. After thorough research, we arrived at HellBoy; a rover with several layers of protection, resisting all the heat of venus, ready for any obstacle, it is equipped with an upper barrier made of LI900, resisting to approximately 1200ºC; a layer of glass wool being the second protective layer for thermal insulation; and finally we have the league of Aich, until we finally get to the beginning of the inner part.
With a very simple operation, the Savonius turbine will help us in the process of generating energy, being an important part in the process of locomotion of the rover. The turbine movement will feed a transmission box, whose objective is to multiply its RPM power, which in turn will feed a spring, which will be the front line for the rover's locomotion, through the rotation of a Carbide mat; the remaining energy generated by the turbine will be directed to the battery where it will be stored.
The NIMH battery will have a special protection, it will be surrounded by a Carbon Carbon insulation in a Li900 box. Composed of 100 cells, our battery will be powered by the rotation of the Savonius turbine together with a photovoltaic panel encapsulated in polycrystalline aluminum oxynitrate. All this load will be necessary for the exchange of information between the satellite about all the data collected with the 3 sensors installed on the rover.
Space Agency Data
NASA, of the space agencies involved in space apps, mainly use data open to the public on the North American agency's portal. These data are the results and analysis of previous missions, research and theses, by the NASA science and space exploration team.

Hackathon Journey
Unique, the experience of "getting out of the comfort zone" and seeking knowledge on a complex subject alone gave us a learning experience that we will never forget. We learned a lot of new things that we never imagined we would learn from the climate of Venus for choosing the ideal materials, electrical for the battery part, 3D prototyping for the assembly of the hover and a lot of math for the calculations.
The inspiration of our team came from the fact that none of the members of the group knew about the subject, and we turned the lack of knowledge on the subject into motivation to learn something new. We split the team between the people who would do the searches, those who would design the 3D hover, and those who would help "test" the ideas, thus speeding up the project completion process. Everything was very rushed due to the short deadline for delivery of the project, but with the internal organization among the members, it greatly facilitated the development of the project. A special thanks goes to Elon Musk who inspired our team to be looking to civilize a new planet.
