About Spaceium
Spaceium is developing unmanned orbital service stations that store and transfer both cryogenic and storable propellants. A visiting spacecraft would rendezvous with a station, after which a modular robotic arm aligns and connects the required transfer interface. The architecture is intended to manage long-duration storage, docking and fuel movement while also carrying tools for selected inspection or repair tasks.
The company is validating individual technologies before deploying a complete depot. An actuator flown on SpaceX Transporter-15 achieved 0.003-degree rotational accuracy in orbit, providing a test of the precise robotic positioning required for future connections. Spaceium’s planned network would let spacecraft refuel after launch, extending operating life, payload capacity and the distance available for later manoeuvres.

Events
- 2026-02-10 - Demonstration - Spaceium validates refueling actuator precision in orbit
The actuator achieved a reported 0.003-degree rotational accuracy in orbit. Spaceium said that precision would produce less than one millimetre of movement at the end of a full-length robotic arm. The actuator is the precision driver for a planned autonomous arm that will grapple spacecraft and align fuel-transfer connections.

The Nicolò payload carried a precision robotic actuator intended for autonomous propellant transfer in orbit. D-Orbit hosted the payload aboard an ION spacecraft launched on SpaceX's Transporter-15 mission. The launch gave Spaceium's refueling hardware flight heritage and began its first in-space test campaign.

The planned demonstration paired Spaceium's cryogenic refueling architecture with The Exploration Company's Nyx spacecraft. The station was to carry cryogenic biomethane and oxygen for the refueling demonstration. The companies also agreed to use Nyx as the host for a Spaceium servicing module in 2026.
