OPEN POSITIONS
We are an international volunteer team developing a wind-driven Mars rover to disrupt Mars exploration using a swarm of low-cost spacecraft. This will not only allow unprecedented science and business cases to be realized, but will also open up deep space exploration to a larger audience. Our goal is to land hardware on Mars by 2030. Started in 2017 by high school students, we have since built 3 rover prototypes, tested two of them in a Mars analogous environment and won numerous competitions. At the moment, we are doing both theoretical mission and rover design studies and analysis as well as building subsystem-level prototypes in preparation for three planned demonstration missions: Firstly, an Earth demonstrator will test the integration of all critical rover functions into one rover and evaluate key science cases in 2025. A deployment demonstrator is planned to be tested on a suborbital test flight in 2025 as well. Lastly, an in-orbit demonstrator to evaluate our electronic systems and software in a space environment will be developed starting in 2023.
For 2022-23, we focus on demonstrating key technologies in a laboratory setting, such as the unfolding, control and resting mechanism of the rover, its navigation and computing and its electrical power supply. We are also maturing the mission, system and subsystem architecture for our Mars demonstrator mission to further constrain the design of our demonstration missions. Also, we are continuing to evolve our science and business cases for the ultimate mission, further developing the utility of our platform. Finally, we are always working on professionalizing our organization to bring us closer to our goal.
To reach our goals and ensure high quality in our work, members should expect to spend around 15 hours a week on average on Team Tumbleweed project work. Please also keep in mind that all positions are on voluntary basis!
