SpaceX achieved one step towards refueling of Starship with a demonstration on the latest Starship test flight March 14. SpaceX said the day of the flight that it performed the demonstration, but neither the company nor NASA provided any updates since then. In that mission, a “target” Starship will launch first and go into orbit, followed three to four weeks later by a "chaser" Starship. Multiple Starship launches will transfer propellant into a depot in low Earth orbit.
