Timeline

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… - source: spaceium.com
2025-12-01 - Demonstration - Spaceium launches orbital refueling actuator on Transporter-15 - 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… - source: spaceium.com
2024-01-15 - Partnership - Spaceium and Space Machines plan cryogenic-refueling mission - Spaceium planned to demonstrate cryogenic fuel storage aboard the Space Machines Company platform. After the storage test, Spaceium planned to transfer the stored cryogenic fuel into a Space Machines spacecraft tank. The companies described the mission as a… - source: spaceium.com
