Dcubed to Demonstrate In-Space Solar Array Manufacturing Capabilities
German startup Dcubed, which specializes in manufacturing space hardware, is expanding into space-based energy with the launch of ARAQYS, a new printable in-space solar array product. On November 18th, the company announced three upcoming demonstration missions that will test ARAQYS ability to build a 2kW solar array in space. Dcubed’s goal is to revolutionize space-based power generation by enabling companies to create large, cost-effective solar arrays as needed.
The reduction in launch costs and increased capacity achieved by industry innovators, such as SpaceX and Rocket Lab, have facilitated a new generation of in-orbit applications, including data centers, high delta-v transportation, direct-to-device communications, and defense constellations, all of which face the significant challenge of meeting escalating power requirements.
ARAQYS addresses this need by offering comprehensive space power solutions. These range from conventional deployable solar arrays to proprietary ISM-based kilowatt-class solar array subsystems, culminating in Space Power Plants designed to deliver beamed energy wherever required. This technology seeks to significantly lower the cost per kilowatt, supporting the infrastructure necessary for future space platforms and directed-energy systems.
According to Dr. Thomas Sinn, CEO of Dcubed, “Our commitment is to pioneer power generation in orbit.” Dr. Sinn’s prior participation in a NASA NIAC study on space-based solar power more than fifteen years ago initiated this strategic direction, driving sustained innovation towards practical in-space energy solutions. With ARAQYS, Dcubed is now combining its technological advancements to provide economically viable, large-scale power systems tailored for the expanding space economy.
The first two demo missions are scheduled for early 2026. Their purpose is to prove that structural components can be constructed to hold a solar blanket capable of generating electricity. Details of the planned missions include:
Araqys-D1 will launch as a 3U satellite in Q1 2026, aiming to construct a 60cm (~2ft) boom in orbit, which will eventually support the solar array.
Araqys-D2 is set to fly on Exotrail’s next spacevan mission in early 2026, demonstrating 3D-printing of a UV-curable resin to reinforce the lower side of a flexible solar blanket. This mission will attempt to create a solar array one meter long.
Araqys-D3 will combine these technologies, attempting to build a solar array measuring 1m by 15m and capable of producing 2kW of power. It is slated to launch on a SpaceX rideshare mission in Q1 2027.
Although solar blanket technology is less efficient than conventional space solar cells, Dcubed anticipates that it significantly reduced costs. Sinn claims an order-of-magnitude drop will ensure Araqys’ commercial viability. “We want to make unlimited power in space a reality,” said Sinn. “We can print as large as we want. There’s no limit… So that’s the whole idea: to bring…the dollar per watt down into the double digits.”
While affordable energy is crucial for many futuristic space applications, such as powering data centers or beaming energy from space, Sinn says Araqys offers more than just lower costs. Araqys enables satellite operators to expand or shrink their solar arrays on demand. According to Sinn, Araqys could manufacture one square meter of solar array in roughly two minutes.
This rapid production allows military satellites to quickly boost their power for uses like directed-energy weapons or high-powered electric thrusters. Satellites can also shed panels to reduce their profile, maneuver quickly, and rebuild elsewhere if needed. For commercial satellites, Araqys could enable replacement of aging solar arrays years later, extending operational lifespans.
With three demonstration missions lined up, Dcubed expects Araqys to enter the market soon, potentially by 2027. Plans call for even larger arrays in following years, a 5kW version in 2028 and a 10kW array in 2029.
