Eclipse, a new small satellite launcher, is being developed by three engineers and will weigh 20 tonnes with a total thrust of 24 tonnes. The project has joined the incubation program at Le Poool x La French Tech Rennes-Saint-Malo.
Engine tests are scheduled for summer 2026 in Brittany. Eclipse will have a length of 18 meters and a diameter of 1.20 meters, capable of delivering payloads of 150 to 200 kg to approximately 600 km altitude.
The fuel will consist of liquefied biomethane and liquid oxygen. The launcher will not be reusable, but designed for revalorization, indicating a focus on sustainability and potential industry impact.
