Alexandre Mangeot is a French aerospace engineer and entrepreneur. He graduated from Arts et Métiers ParisTech and holds a PhD co-funded by CNES in energetic from the University of Orléans, where he specialized in hybrid rocket engines at the PRISME laboratory.
Early in his career, he worked at Expliseat to contribute at the development of the lightest aircraft seats. He led mechanical innovations on the primary structure and accessories and co-authored a patent for a locking mechanism on folding tray tables.
In 2016–2017, Mangeot served as commander of the Mars160 analog mission organized by The Mars Society. The mission unfolded in two parts: one in the Utah desert and the other on Devon Island in the Canadian Arctic—both chosen for their Martian-like conditions. As commander, he led a six-person international crew, coordinating scientific research, technical activities, and group dynamics in extreme isolation.
Drawing from these experiences, he co-founded HyPrSpace in 2019, a French startup developing hybrid rocket propulsion systems that use solid fuels and liquid oxidizers. As CTO and CEO, he is leading the development of the OB-1 micro-launcher, designed to place payloads of 250–300 kg into low Earth orbit, with a strong focus on simplicity, robustness, and scalability.
