Sidus Space Announces Successful On-Orbit Operation of FeatherEdge™ Gen-2 Aboard LizzieSat®-3

Commercial Availability and Third-Party AI Integration Unlock New Revenue Streams Across Multiple Markets

Sidus Space (NASDAQ: SIDU), (the “Company” or “Sidus”), an innovative, agile space mission enabler, today announced the successful on-orbit operation of its advanced onboard edge computer, FeatherEdge™ GEN-2, integrated into the ongoing commissioning of LizzieSat^®-3 (LS-3).

FeatherEdge™ GEN-2 is now flight-proven and commercially available, offering 100 trillion operations per second (TOPS) of AI processing power in a space-hardened, compact format. By leveraging NVIDIA’s Jetson Orin™ NX module, this advanced onboard computer is built to perform in harsh radiation environments—making it ideal for sustained low Earth orbit missions. After successful on-orbit validation, FeatherEdge™ GEN-2 is now commercially available for customers seeking compact, high-performance AI processing solutions.

“We are excited to share that FeatherEdge™ GEN-2 is fully operational onboard LizzieSat^®-3,” said Carol Craig, CEO of Sidus Space. “What sets this technology apart is its broad market applicability. While designed for space, FeatherEdge™ GEN-2 has the potential to drive revenue across multiple domains—including defense, intelligence, maritime, aviation, and terrestrial remote sensing—by enabling near real-time data processing at the edge.”

In addition, Sidus is now enabling third-party algorithm integration aboard LizzieSat^®-3, allowing government and commercial space domain customers to test and deploy proprietary AI solutions in orbit without building their own satellite infrastructure.

As LizzieSat^®-3 continues to perform successfully through its commissioning phase, we believe the platform is demonstrating its potential to become a flexible, revenue-generating asset with dual-use applicability far beyond space. FeatherEdge™ GEN-2 opens up high-value opportunities for recurring revenue through hardware sales, data processing services, and technology integration—positioning Sidus to capitalize on future growth across both government and commercial sectors.
