We’re starting to learn more details about how SpaceX will refuel Starships in low-Earth orbit.

This appears to be confirmation of mission success from tonight’s launch aboard a SpaceX Falcon 9. It was expected to take more than three hours to inject the Galileo satellites into a circular Medium Earth Orbit.

SpaceX is set to launch two European Galileo navigation satellites at 8:34pm EDT.

Based on SpaceX's mission page, this mission will operate under an NRO-type level of secrecy. Weird. All the previous Galileo flights on Soyuz and Ariane were fully public.
