Launched · 2025.11WISDOM
Two 3U satellites separating from a 6U unit test collision avoidance under ESA NAVISP; C3S combines its platform, OWL system and integration expertise for coordinated operations in space.
Programme source ↗C3S / MISSION ATLAS
Engineering expertise.
Mission by mission.
From flight-proven platforms to new ESA programmes. Science, Earth observation, communication and space safety, with C3S contributing in different roles.
Status: September 2026. Future launch years reflect plans from C3S and programme owners, not a fixed schedule. Photographs and renderings illustrate the referenced programmes.
