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

Sidus Space 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.”
