SpaceX's Starship program continues advancing toward orbital refueling demonstrations that require two vehicles to rendezvous and dock in low Earth orbit for propellant transfer, a critical step for crewed lunar missions. Recent Flight 14 achieved the first orbital insertion in September 2026, while Flight 15 targeted for mid-November focuses on dual tower catches of the booster and upper stage to build rapid reusability. No Starship-to-Starship docking has occurred yet, though company statements point to a dedicated refueling test early in 2027 once catch and turnaround capabilities mature. Regulatory approvals, vehicle hardware readiness, and iterative test results remain key swing factors that could accelerate or delay the milestone.
