Starship orbital refueling demo by end of 2026

“I'd say towards the end of the year.”
— Elon Musk · Jan 6, 2026 · Moonshots #220 — answer on when Starship orbital refueling happens in 2026 ↗
What actually happened

Fetched Sep 10 2026: Wikipedia's Starship Propellant Transfer Demonstration page still lists the ship-to-ship cryogenic transfer as a planned demo NET late 2026, not flown. SpaceDaily (Aug 27) and NASA/GAO 2026 assessments still list it as an unattempted 2026 HLS milestone. Flight 13 (Jul 24) had no second Starship, rendezvous, or propellant transfer; Flight 14 has not launched. Deadline end-2026. Status stays pending.

Orbital propellant transfer is the gating technology for any Starship Mars mission, and Musk has called off-Earth refueling the biggest hurdle to hitting the November-December 2026 Mars window. On the Moonshots podcast he placed the first orbital refueling demonstration toward the end of 2026 — a hard, checkable milestone.
