Announcing the 2026-27 COSMIC Capstone Challenge (C3)! The Consortium for Space Mobility and ISAM Capabilities (COSMIC) is a nationwide coalition working to accelerate adoption of domestic in-space servicing, assembly, and manufacturing (ISAM) capabilities.
COSMIC’s C3 Challenge is a competition that invites students to develop conceptual missions & designs for spacecraft operations in-orbit or on the lunar surface.
Six challenge tracks are offered in 2026-27: (1) Orbital Manufacturing and Assembly; (2) Lunar Operations; (3) Orbital Servicing; (4) Construction; (5) In-Space for Earth; (6) Architecture of Autonomous Space Clusters
Registered teams will be paired with experienced mentors from industry, government, and research organizations who will guide students with meetings, provide problem-focused advice, and support milestone deliverables — culminating in a 24-minute final presentation at the C3 Final Showcase in April 2027.
Who Can Join: C3 is open to US-based college students. In addition to class-based teams, students can pursue C3 through student clubs, directed study or independent study.
