Turion Space develops in-space infrastructure to tackle orbital debris and space situational awareness, using DROID satellites and the STARFIRE OS. The DROID satellites provide imaging and space-object tracking, while Starfire NEXUS lets customers deploy their own software and AI workloads on the satellites for on-orbit computing. The company designs and builds both hardware and software in-house, including mission planning, satellite bus, and propulsion, enabling faster execution and tighter control than many rivals. Its goal is to grow a space infrastructure platform that improves space traffic management and debris removal, serving both government and commercial customers in a multi-billion-dollar market.

Turion Space Corp. Acquires Tychee Research Group to Accelerate Autonomous Space Operations and Mission Engineering

Turion Space Corp. acquires Tychee Research Group to accelerate autonomous space operations and mission engineering. Acquisition brings Tychee Mission Planning Library (TMPL) and a world-class astrodynamics team into Turion's Starfire platform, enabling faster, more resilient, software-defined space missions Turion Space Corp. ("Turion"), a space infrastructure company that builds and operates mission-grade spacecraft and space operations software, today announced it has completed the acquisition of Tychee Research Group ("Tychee"), a Los Angeles-based company specializing in high-speed, high-fidelity astrodynamics and advanced mission engineering. Tychee's flagship product, the Tychee Mission Planning Library (TMPL), is a high-performance astronautics software library built to support the full space system lifecycle. The product suite extends from concept design and modeling and simulation, to ground software and flight software running onboard spacecraft. TMPL is trusted in mission-critical environments and is designed for secure deployment and embedded execution, bringing mission engineering closer to real-time operations. With Tychee joining Turion, TMPL will be integrated into Turion's Starfire software ecosystem. This unites mission planning, maneuver optimization, and autonomous operations into a single, software-defined platform that scales from desktop analysis to on-orbit execution. "Turion's mission is to unleash the potential of Earth orbit, and software is what makes spacecraft usable at scale," said Ryan Westerdahl, CEO and Co-Founder of Turion Space Corp. "This acquisition brings an exceptional team and mission planning capability into Turion. Our mission-engineering logic will support everything from trade studies to operational decision-making and on-orbit autonomy." Space missions are demanding faster planning cycles, higher fidelity, and the ability to adapt in real time in constrained and secure environments. Traditional mission design tools were built for the era of desktop-centric workflows, limited integration into flight software, and slow paths from analysis to operations. Tychee and Turion are combining to remove those bottlenecks. The integration of Starfire + TMPL creates an embeddable mission-engineering SDK paired with operator applications that run the same algorithms on the ground and onboard spacecraft, backed by secure deployment options and a web-driven user experience designed to broaden adoption. With Tychee's mission engineering and astrodynamics capabilities embedded into Turion's platform, the combined company will accelerate progress across: * End-to-end mission ownership: Turion expands its ability to own outcomes across the full mission stack so operators can move faster from intent to execution. * Autonomous, software-defined operations: TMPL's performance and flight-software orientation strengthens Starfire's ability to support advanced missions, including real-time maneuver planning and autonomy-oriented workflows. * Scaled adoption across the space ecosystem: TMPL's product-first library model expands Turion's reach across government, commercial, academic, and partner organizations. Rob Brady, founder of Tychee Research Group, will join Turion as Chief Product Officer, leading the product strategy and go-to-market execution for TMPL within the Starfire platform. "I'm excited to bring TMPL to market with Turion," said Rob Brady, Chief Product Officer of Turion Space Corp. and founder of Tychee Research Group. "TMPL was built to be fast and usable across modeling and simulation, ground software, and flight software. Combined with Turion's Starfire platform and spacecraft capabilities, we're delivering mission-engineering infrastructure that is operationally native." Tychee and TMPL continue to support multiple clients and advanced, operational programs. TMPL will support current users and mission needs, with expanded integration and product evolution underway as part of Turion's Starfire portfolio. Financial terms of the transaction were not disclosed. About Tychee Research Group. Tychee Research Group, founded in 2018 and based in Los Angeles, California, specializes in space mission engineering, modeling and simulation, and advanced algorithms for dual-use space capabilities. Tychee's flagship product, the Tychee Mission Planning Library (TMPL), delivers high-performance, high-fidelity astrodynamics and mission planning functionality designed to span analysis, operations, and embedded onboard execution.
