HyPrSpace has raised €21 million to perform its Baguette One suborbital test flight and accelerate the development of its OB-1 rocket.

HyPrSpace is developing a hybrid propulsion system that uses solid HDPE fuel and a cryogenic liquid oxygen oxidiser. The company expects to use its propulsion system for the first time aboard a suborbital test flight called Baguette One, which is scheduled to be launched in 2026 from a French Ministry of Defence missile test site in mainland France. It will then move on to an initial orbital test flight using its larger Orbital Baguette One (OB-1) rocket.
