ROTTERDAM / PASADENA — Sophia Space has picked Spherical to lead the design and delivery of the complete Electrical Power System (EPS) and battery architecture for Sophia Space's Athena Project. Spherical is going to deliver the full Electrical Power System (EPS) and battery architecture, from design through flight.
This marks our first major US commercial deal, and a partnership we see as a foundational step toward a much larger future for both companies. Spherical was founded with the idea to design aerospace silicon from the ground up, and that same engineering rigor carries through to the power systems we build on top of it, including the EPS we are delivering to Sophia.
"Athena is an important milestone for Sophia Space as we move our orbital computing technology toward flight, and having the right partners around that technology is critical," said Rob DeMillo, CEO and Co-Founder of Sophia Space. "We selected Spherical because of the depth of its power systems expertise and its ability to work closely with our team on solutions tailored to the mission. This partnership brings us another step closer to demonstrating TILE in orbit."
The Athena mission is an in-orbit demonstration of Sophia's TILE which is a solution to a common industry bottleneck: getting significant compute power close to sensors in orbit without overheating. Their architecture uses flat, modular compute slabs that integrate power, processing, and passive thermal management. This allows heat to radiate directly into space instead of relying on active cooling, which means satellites can process data in orbit rather than waiting for a downlink window.
Our role is to build the hardware that keeps the platform running. We are providing a flight-qualified EPS from our modular product line, tailored specifically to TILE's unique mechanical and interface requirements. Our engineering team is working closely with Sophia's from the requirements phase all the way through qualification.
"Sophia Space is leading the way in the next generation of on-orbit compute. We're super excited to support them by powering the mission. The Sophia team has been wonderful to work with and we look forward to our continued relationship." — Thomas Parry, CEO and founder, Spherical
Technical work on the IOD has begun, on Sophia's Athena mission, with an eye on the constellation that follows. The proof is in orbit.
About Spherical Based in Rotterdam, Spherical provides full-stack space electronics designed to meet the rigorous demands of the modern orbital economy. Our core focus is on high-performance power systems (including PDUs and PCDUs) and control electronics. By developing our own system-specific silicon, we deliver electronics that are highly reliable, software-configurable, and fundamentally superior in Size, Weight, and Power (SWaP) efficiency. We don't just supply hardware; we architect the reliable electronics foundation required for complex space operations. Learn more at spherical.si.
