Spaceium validates refueling actuator precision in orbit
Spaceium reported that its robotic refueling actuator achieved 0.003-degree rotational accuracy during on-orbit testing after the Transporter-15 launch.

Evidence notes
- 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.
Company context
Spaceium builds automated infrastructure for in-space refueling and repair. Its planned service stations store propellant and use a modular robotic arm to grapple customer spacecraft, align transfer connections and exchange tools or hardware.
