Sidus Space Advances $120M Agreement with Lonestar, Selects Atomic-6 as Solar Array Partner for Cislunar Data Satellite Mission

CAPE CANAVERAL, Fla.--(BUSINESS WIRE)--Sidus Space (NASDAQ: SIDU), (the “Company” or “Sidus”), an innovative space and defense technology provider, today announced the next milestone under its expanded $120 million preliminary agreement with Lonestar Data Holdings Inc. to support the world’s first lunar data centers. Atomic-6 has been selected to supply its Light Wing™ solar arrays which are expected to power Sidus’ LizzieSat® satellites supporting Lonestar’s cislunar data storage constellation.

The all-composite, redeployable Light Wing™ arrays deliver industry leading power-to-mass performance, contributing to mission assurance and overall efficiency. Atomic-6’s solution was selected after a rigorous technical and commercial review to meet the demands of secure, redundant satellite operations in the harsh cislunar environment.

Sidus’ versatile LizzieSat® platform offers a scalable solution for complex missions beyond low Earth orbit, including future lunar operations. The Company’s end-to-end capabilities, from design and integration to launch and operations, are being applied to support Lonestar’s phased deployment of resilient cislunar data infrastructure.

“This collaboration marks a key advancement as we evolve LizzieSat® in executing our vision for lunar satellite services,” said Carol Craig, CEO of Sidus Space. “We’re proud to lead a commercial-first initiative that not only delivers data security solutions in cislunar space but also reinforces our LizzieSat® platform’s adaptability and utility across deep space operations.”

The constellation aims to deliver secure, tamper-resistant data storage, immune to threats such as natural disasters, geopolitical instability, and cyberattacks. The selection of Atomic-6 underscores the importance of high-efficiency power systems in enabling this next-generation architecture.

Light Wing™ arrays delivers up to 200 watts per kilogram, four times more power than comparable systems, offering exceptional efficiency and reliability.

“We’re excited to welcome Atomic-6 as a trusted partner in this ambitious program,” Craig added. “Their innovative solar arrays enhance our ability to meet the unique demands of cislunar deployment.”

This announcement follows Sidus Space’s March 2025 execution of an extended and amended preliminary agreement with Lonestar. As program development accelerates, Sidus remains committed to advancing commercial applications in cislunar space and enabling next-generation services through its adaptable LizzieSat® platform.
