ASRO and Ethereal Space Partner to Advance Space Weather Instrumentation with ESA Commercialisation Gateway Support

Turku, Finland — 29 August 2025 — ASRO – Aboa Space Research Oy and Ethereal Space, Inc. today announced a new strategic partnership to develop and deploy advanced space weather instruments designed to monitor energetic charged particles in near-Earth space. The collaboration is being supported by the European Space Agency’s ScaleUp Invest program, which fosters commercial innovation and accelerates market-driven solutions in space.

The partnership will focus on integrating ASRO’s expertise in energetic particle instrumentation with Ethereal Space’s next-generation satellite constellation. By combining proven scientific capability with scalable small-satellite platforms, the two companies aim to deliver critical data for operational space weather forecasting and nowcasting.

“Space weather has direct and growing impacts on satellites, aviation, power grids, and navigation systems worldwide,” said Jussi Lehti, CEO, ASRO. “Our instruments are designed to measure energetic charged particles with high accuracy and reliability, enabling better protection of critical infrastructure.”

Ethereal Space’s constellation will serve as the deployment platform for these instruments, ensuring continuous, real-time coverage of the space environment. “By flying ASRO’s particle sensors on our satellites, we will provide datasets that are essential for both government and commercial users,” said Shawn Cochran, CEO of Ethereal Space. “This partnership strengthens our ability to deliver actionable insights on space weather that safeguard both technology and society.”

The ability to monitor energetic charged particles in situ is central to improving both forecasts and nowcasts of space weather conditions. By expanding global measurement coverage, ASRO and Ethereal Space aim to reduce uncertainty in models, support timely warnings of solar storms, and provide data services that enhance resilience against disruptions caused by extreme space weather events.

This partnership represents a key milestone in aligning scientific innovation with commercial deployment, accelerating private industry’s leadership in operational space weather capabilities supported by the ESA ScaleUp Invest framework.
