Space Debris Mitigation Collaboration Expanded
Arianespace and BULL Advance Feasibility Study, Plan Test Flight
In 2024, an MOU (Memorandum of Understanding) to collaborate on space debris mitigation was signed by Arianespace and BULL, based on a common understanding of the importance of sustainability in space.
“A sustainable use of space is a priority for us, and we are most keen on pushing forward emerging solutions that further sustainable activities in space.”

Under the MOU, Arianespace and BULL performed a first step of a feasibility study to implement the HORN PMD (Post Mission Disposal) device, which is being developed by BULL, on the Ariane 6 DLS (Dual Launch System). The study showed that an installation of the HORN on the Ariane 6 DLS would be effective.
Both parties will now collaborate on the next step, targeting a flight demonstration of the HORN on the Ariane 6 DLS. Available launch slots are being identified, starting from 2027.
The HORN PMD is a very large deployable sail, developed by BULL, which accelerates the re-entry maneuver after the mission ends.
“As a historic leader in bringing satellites to orbit and beyond, Arianespace has always been committed to a responsible use of space. This innovative collaboration with BULL, a start-up pioneering solutions to mitigate space debris, showcases Arianespace’s dedication to being at the forefront of such critical issues. A sustainable use of space is a priority for us, and we are most keen on pushing forward emerging solutions that further sustainable activities in space,” said David Cavaillolès, Chief Executive Officer of Arianespace.
“Under the vision of ‘Making interplanetary travel the norm’, BULL continues to take on the challenge of establishing a new standard for space utilization from Japan to the world,” said Yasuhito Uto, CEO of BULL. “Advancing our collaboration with Arianespace, a world-leading company representing Europe, and undertaking the initiative to assess the feasibility of and consider the actual application of our Post Mission Disposal (PMD) device, HORN, to the Ariane 6 launch vehicle marks a profoundly significant step toward enhancing the sustainability of the space environment. BULL will continue to strengthen international collaboration based in Japan and Europe, and steadily contribute to the realization of sustainable space development.”
Arianespace signed the ESA Net Zero Space Agreement in 2021 and follows the French law on Space operations (FSOA). A proactive commitment to sustainable space has been a primary priority for the company. Collaboration with BULL will enable Ariane 6 to further contribute to meet the target of sustainability, preventing the creation of space debris.
