High-Level Project Summary
In Nextgen wingineering we develop a solution to the problem of a power system for a rover in the cold night of Venus, we start from the MMRTG battery of the Perseverance Mars Rover, taking advantage of the low temperature we can keep our battery stable and thus provide energy to our rover for 60 days and given that the useful life of our battery of several years we can implement the modification of a rover so that its maximum speed is 3-6 km/h and thus avoid the venusian day and be able to explore all venus while the batteries give uninterrupted power

Detailed Project Description
We use a MMRGT to power our rover on the dark side of venus for at least 60 earth days but since our battery can last up to 20 years until radio isotope emissions get too low we can keep our rover on venus with unlimited power , we will modify the rover so that it can move at 5 km/h and thus move along with the night so as not to have to withstand the devastating temperatures of 460 ° C during the day, we use Austenitic Stainless Steel so that the acidic atmosphere of venus does not wear our structures and we also use ceramic hex tiles to have a good thermal dissipation when needed, our nominal power output would be 300 w/h which is enough for a rover like Mars Perseverance
Space Agency Data
We use the NASA data base and public information to complement our materials list
Hackathon Journey
Our experience during this international hackathon nasa space apps challenge seemed amazing to us, how so many people can get together to spend a very good weekend full of ideas, of knowledge, it is fascinating.
We learned many new things about materials, structure, thermodynamics, gravity, pressure, electronics, control, etc...
My team was inspired by the difficulty of this problem and nothing like a good challenge due to the extreme temperature and acid atmosphere.
Our approach to developing this solution was to find a part of the solution that has already been used and stolen and adapt it and where possible make it more efficient and better.
