HyPrSpace (Hybrid Propulsion for Space) is a rocket startup, founded in 2019, from Bordeaux, Nouvelle-Aquitaine, France. It develops orbital (Orbital Baguette-1/OB-1, pronounced Obi-wan) and suborbital (Baguette One) launch vehicles and hybrid propulsion systems.
In 2022 it has raised €1.1 million to develop its rocket.
In 2024 as part of a consortium (with the companies CT Ingénierie, SpaceDreamS and Telespazio France) it has raises €35 million to develop their launcher Orbital Baguette One (the "Le Projet Agile de Développement d'Accès à l'espace 1" - PADA1 - project), 60 percent of the funding from the French government - as the winner of the France 2030 program supported by the State.
Baguette One is 7 metres tall, single-stage, with a payload capacity of 300 kilograms. The first suborbital mission is planned for 2026.
Orbital Baguette-1 (OB-1) - 16 metres tall - is a micro-launcher with a payload of 250 kg to 400 km LEO (low Earth orbit).
The hybrid engine use solid fuels (including HDPE) in combination with a liquid oxidizer and doesn't need a turbo pump. On 11 July 2024 it was completed with success the first hot fire test of its Terminator hybrid rocket motor.
