Blackswan Space Secures €2.5M to Advance Autonomous Spacecraft
Blackswan Space secured €2.5M Seed funding led by Iron Wolf Capital to accelerate commercialization of its autonomous spacecraft navigation.

The big picture: Vilnius-based space tech company Blackswan Space, which develops autonomous navigation systems for spacecraft, has secured €2.5 million in a seed round. The funding was led by Iron Wolf Capital, with participation from existing investors Lemonade Stand and former NanoAvionics co-founder Linas Sargautis, alongside new investors NGL Ventures and Tomas Žalandauskas. Blackswan Space develops technologies designed to enable spacecraft to autonomously navigate and operate around other objects in orbit.
Why it matters:
- Orbital Congestion: Autonomous navigation is crucial for managing the increasing satellite traffic and preventing collisions in Earth’s orbit.
- Mission Flexibility: Reducing reliance on ground control enables more complex and responsive in-orbit operations, such as refueling, servicing, and debris removal.
- Strategic Capability: In-space refueling, a key application of Blackswan Space’s RPO technology, is vital for extending satellite lifespans and supporting future deep-space missions.
How it works:
- Vision-Based RPO: The company’s RPO Kit is a plug-and-play payload that uses advanced vision-based detection and tracking for precise rendezvous and proximity operations.
- Simulation & Design: Blackswan Space offers a Mission Design Simulator, allowing for rigorous testing and optimization of autonomous space missions before deployment.
- In-Orbit Demonstration: The RPO technology is slated for use by US-based in-space refueling company Orbit Fab for a planned 2028 mission, demonstrating in-space refueling in Europe.
The catch: Developing reliable, fault-tolerant autonomous systems for the harsh space environment presents significant engineering challenges. The dual-use nature of space autonomy, particularly for rendezvous and refueling, can also face complex international regulations and export controls. The market for space autonomy is attracting increasing investment, leading to competition from established aerospace players and other specialized startups.
