ZephyrIoT has reached orbit for the second time. Antmicro and Aethero flew the open source real-time operating system on a CubeSat aboard a SpaceX Falcon 9 rideshare in March 2026.
The same open source RTOS used in critical embedded systems on Earth is now operating in space.
Antmicro supports Aethero next-gen space computers with Zephyr-controlled onboard computers built around NVIDIA Jetson Orin and Thor edge AI platforms.
The CubeSat launch marked the latest deployment of the technology beyond Earth's surface.
