Gama Space with Sebastian Scholz
Notes de l’épisode
Space exploration demands software that is reliable, efficient, and able to operate in the harshest environments imaginable. When a spacecraft deploys a solar sail millions of kilometers from Earth, there's no room for memory bugs, race conditions, or software failures. This is where Rust's robustness guarantees become mission-critical.
In this episode, we speak with Sebastian Scholz, an engineer at Gama Space, a French company pioneering solar sail and drag sail technology for spacecraft propulsion and deorbiting. We explore how Rust is being used in aerospace applications, the unique challenges of developing software for space systems, and what it takes to build reliable embedded systems that operate beyond Earth's atmosphere.
About Gama Space
Gama Space is a French aerospace company founded in 2020 and headquartered in Ivry-sur-Seine, France. The company develops space propulsion and orbital technologies with a mission to keep space accessible. Their two main product lines are solar sails for deep space exploration using the sun's infinite energy, and drag sails—the most effective way to deorbit satellites and combat space debris. After just two years of R&D, Gama successfully launched their satellite on a SpaceX Falcon 9. The Gama Alpha mission is a 6U cubesat weighing just 11 kilograms that deploys a large 73.3m² sail. With 48 employees, Gama is at the forefront of making space exploration more sustainable and accessible.
