What We Do

Turion Space is building the infrastructure to secure and sustain the future of space. Founded to address the growing need for space domain awareness, in-space servicing, and debris mitigation, Turion designs, builds, and operates spacecraft with real-world operational capability. Our vehicles are built for national security and commercial missions that require speed, autonomy, and resilience.

We believe the next chapter of space operations will be defined by who can act, not just observe. That’s why we’re focused on building platforms that move fast, adapt in orbit, and solve problems ranging from satellite servicing to tactical intelligence gathering.

We successfully launched our DROID.001 satellite in June 2023 and DROID.002 in March 2025. DROID.003 is scheduled for launch in 2026.

Why Work With Us

Turion Space is where startup grit meets real space missions. We build and fly spacecraft for defense, servicing, and domain awareness. No red tape, no sidelines, just hands-on work that matters.
