Production

  • Current production: One Starship every 2-3 weeks.
  • Goal: Produce 1,000 Starships annually (approximately 3 per day) across two facilities in Texas and Florida.
  • For comparison:

Starlink V3

  • Planned production: 5,000 Starlink V3 satellites per year, each comparable in size to a Boeing 737.
  • For comparison:

Reuse

  • Goal: Reuse a booster within 1-2 hours of landing by catching, placing on the launch pad, refueling in 30-40 minutes, stacking a Starship, and relaunching.
  • Plan to demonstrate booster catching within 2-3 months.
  • Starlink terminals feature Mars transfer trajectory diagrams, as Starlink revenue supports the Mars mission.

Orbital Refilling

  • Planned demonstration of orbital refilling in 2026.
  • If successful, SpaceX aims to send an uncrewed mission to Mars by the end of 2026, aligning with the Earth-Mars transfer window every 26 months.

Reliable Heat Shield

  • Developing a heat shield to withstand Mars' carbon dioxide atmosphere, which produces more free oxygen as plasma, increasing oxidation compared to Earth’s atmosphere.
  • Estimated timeline: Several years to perfect a reliable material.

Comparing Starship Versions

V16950100–150
V27152100–150
V37352100–150
V48161200
  • Planned launch of Booster and Ship V3 by the end of 2025.

Roadmap to Mars

  • Estimated mass required for a self-sustaining Mars civilization: 1 million to 10 million tons.
