Evidence
Proven Execution
Sierra Space credibility is grounded in hardware, facilities, and technical depth rather than in ambition. Recent public milestones include the Dream Chaser® spaceplane completing environmental testing at NASA facilities and returning to Colorado, and the opening of the Power Station technology center in Broomfield, announced June 2025.
Satellite production at Victory Works in Centennial, propulsion work in Wisconsin, and precision mechanisms in North Carolina extend that base across the portfolio.
Lifecycle
Built Across the Mission Lifecycle
Architecture, design, manufacturing, integration, test, and qualification connect Sierra Space’s spacecraft, subsystems, and infrastructure programs. The work links mission requirements to hardware development and verification.
