The two companies have taken a new step in their collaboration to improve the sustainability of European space missions. The two companies are working together on developing and integrating the HORN PMD system, which is an innovative technology designed to reduce the generation of space debris at the end of each mission.
Their cooperation began in 2024 with the signing of a Memorandum of Understanding (MoU) to promote responsible space practices. An initial feasibility study has since been completed, confirming the effectiveness of the HORN PMD device on the Ariane 6 launcher’s dual launch system (DLS).
The next step is to conduct a flight demonstration of the system after 2027, once the appropriate launch windows have been defined. The HORN PMD consists of a large deployable sail that is activated at the end of the mission to facilitate the controlled re-entry of the vehicle’s components, thereby significantly reducing the accumulation of orbital debris.
By signing the Net Zero Space Agreement promoted by the European Space Agency (ESA) in 2021, Arianespace has reinforced its commitment to sustainability and compliance with French regulations on space operations (FSOA). The company considers preserving the space environment to be a strategic focus of its activity, in line with the principles of responsibility that guide its launches and missions.
Arianespace CEO David Cavaillolès emphasises that, as a long-standing player in satellite deployment, “it is our duty to ensure that space remains accessible and safe for future generations”. Our collaboration with BULL demonstrates our commitment to supporting technological solutions that promote a more sustainable and efficient space industry.”
Through this agreement, Arianespace and BULL are helping to develop new practices that will put Europe at the forefront of sustainable space. This is also in line with the sustainability and safety objectives promoted by Spain, and Andalusia in particular, where the space sector continues to establish itself as a leader in technological innovation and environmental commitment.
