Astrobotic Develops Clavius-S Lunar Orbital Tracker

Astrobotic announced Dec. 4, 2025 that it secured a NASA Small Business Innovation Research Phase I award to develop Clavius-S, a visible-band imaging sensor to detect and track spacecraft in low lunar orbit from the Moon's surface in real time. The modular payload will integrate with Astrobotic's LunaGrid power nodes to provide networked space domain awareness out to about 1,000 kilometers.
Key Points
- 1Secures NASA SBIR Phase I award to build Clavius-S lunar surface visible-band tracker
- 2Provides near-overhead, low-glare observations to improve detection of non-transmitting orbiting objects
- 3Allows deployment of networked space-domain-awareness services and real-time conjunction assessment tools
Scoring Rationale
Notable NASA-funded lunar sensor advances surface SDA capabilities, but Phase I status limits near-term deployment readiness.
