Starship has reached orbit after a decade of development, but key steps such as orbital propellant transfer are still missing. A Mars attempt is now pushed back beyond the 2026 launch window.

01Summary
- 01Elon Musk unveiled plans for a Mars vehicle at the International Astronautical Congress in Guadalajara, Mexico, in 2015.
- 02SpaceX’s Starship reached orbit for the first time on 28 September 2025 during its 14th test flight.
- 03Analysts say Starship is now being used to cut Starlink launch costs, with more than 11,000 satellites already in orbit and Starlink V3 expected to grow to 100,000 spacecraft.
- 04The story says orbital propellant transfer has not yet been demonstrated, and that step is needed for missions to the Moon or Mars.
- 05Musk said in 2025 there was a '50/50' chance of a Mars run in 2026, but the next Mars launch window opens in late 2028.
02Why it matters
The rocket’s progress affects SpaceX’s Mars ambitions, NASA’s Artemis plans and the future cost of launching Starlink satellites. The timing also matters because the missed 2026 Mars window pushes any human Mars attempt further into the future.
