The Red Planet and Earth align properly for interplanetary missions just once every 26 months. The next such opportunity comes in 2026 between the months of November and December, and SpaceX will try to hit it; the goal is to send five Starship Version 3 vehicles to the Red Planet to prove out the vehicle and its associated tech, Musk said.

The SpaceX CEO outlined upcoming changes to the rocket while staying committed to a 2026 mission to the Red Planet.

Two days after the latest in a string of test-flight setbacks for his big new Mars spacecraft, Starship, Elon Musk said on Thursday he foresees the futuristic vehicle making its first uncrewed voyage to the red planet at the end of next year.
