CAPE CANAVERAL, Florida: Sidus Space, a leading space and defense technology provider, has announced a significant milestone in its $120 million expanded agreement with Lonestar Data Holdings Inc. to develop the world’s first lunar data centers. The company revealed that Atomic-6 has been chosen to supply its innovative Light Wing solar arrays, which will power Sidus’ LizzieSat satellites integral to Lonestar’s cislunar data storage constellation.
The Light Wing solar arrays, made entirely from composite materials and designed to be redeployable, offer industry-leading power-to-mass performance. This cutting-edge technology delivers up to 200 watts per kilogram—four times the power density of comparable systems—ensuring exceptional efficiency and reliability in the harsh environment of cislunar space. After a rigorous technical and commercial evaluation, Atomic-6’s solution was selected to meet the stringent demands of secure, redundant satellite operations beyond Earth orbit.
Sidus’ versatile LizzieSat satellite platform supports complex missions beyond low Earth orbit, including future lunar operations. The company’s comprehensive capabilities span satellite design, integration, launch, and on-orbit operations, enabling it to support Lonestar’s phased deployment of resilient cislunar data infrastructure. LizzieSat is engineered to provide scalable and adaptable satellite solutions tailored to the unique challenges of deep space.
Carol Craig, CEO of Sidus Space, emphasized the strategic importance of this collaboration: “This partnership marks a key advancement as we evolve LizzieSat in executing our vision for lunar satellite services. We’re proud to lead a commercial-first initiative that not only delivers data security solutions in cislunar space but also reinforces our platform’s adaptability across deep space operations”.
Lonestar’s cislunar constellation aims to offer secure, tamper-resistant data storage solutions designed to withstand threats such as natural disasters, geopolitical instability, and cyberattacks. The initiative represents a new frontier in data sovereignty and resilience by leveraging the Moon and cislunar space as a secure data storage environment. The integration of Atomic-6’s high-efficiency solar arrays is critical to powering this next-generation satellite architecture.
Craig added, “We’re excited to welcome Atomic-6 as a trusted partner in this ambitious program. Their innovative solar arrays enhance our ability to meet the unique demands of cislunar deployment”.
