Sidus Space, an innovative space and defense technology company, announced the execution of a Commercial Pathfinder Mission Agreement with Lonestar Data Holdings, for the design and integration of Lonestar’s high-capacity Digital Data Storage Payload, featuring edge processing capabilities, onto LizzieSat-5, a Low Earth Orbit (LEO) satellite within Sidus’ LizzieSat micro-constellation.

Under the terms of the agreement, Sidus will design, develop, and integrate one Lonestar payload onto LizzieSat-5, along with arranging deployment and payload commissioning in coordination with Lonestar. The mission serves as the roll out of Lonestar’s commercial offering for in-space data storage and edge processing technologies, designed to establish sovereign, secure, and scalable orbital data infrastructure where data from Earth can be uplinked, stored long-term, processed, and downlinked as needed from onboard a spacecraft.

“This mission exemplifies how modular satellite design and integrated partnerships can rapidly advance commercial space innovation,” said Carol Craig, Founder and CEO of Sidus Space. “By hosting Lonestar’s Data Storage Payload on LizzieSat-5, we’re not only enabling new applications for edge computing in orbit but also strengthening the foundation for secure, scalable data networks across LEO.”

In accordance with the agreement, the mission aims to validate long-term, sovereign data retention and near real-time analytics capabilities from space. Sidus will maintain operational control of the satellite through Launch and Early Orbit Phase (LEOP) and commissioning at an orbital altitude of approximately 500-550 km.

“After our successful test flights earlier this year, this mission with Sidus represents the perfect next step for our commercial service.” said Chris Stott, CEO of Lonestar Data Holdings.

The LizzieSat-5 mission builds upon the growing collaboration between Sidus and Lonestar, following the companies’ earlier preliminary $120 million agreement for future lunar data storage spacecraft, underscoring Sidus’ expanding role as a trusted mission enabler across both LEO and cislunar domains.
