Refuelling seems to be more like to be done by bolting another engine + propellant, than actually refuelling the in-service engine, based on current concepts.

- jofer 5y agoSome commercial companies (e.g. Orbit Fab) are selling refuelling ports for satellites, FWIW. NASA put a lot of research into it as well, IIRC. For the JWT it's probably quite different, but for commercial earth observation sats, there are lots of folks considering including some of the refuelling port designs in current hardware even though the actually "refuel in space" service isn't available yet.
