Exoplanet astronomer at Cornell University's Carl Sagan Institute Ryan MacDonald (known on social media as Martian Colonist) has created an infographic of SpaceX's aspirational timeline for Starship's first missions to the Moon and Mars.
We estimate realistically the timeline will slip for a few years with #dearMoon mission happening in 2025, Lunar Starship demo landing in 2026, humans returning to the Moon in 2027, first cargo mission landing on Mars in 2027 and first crew mission landing on Mars in 2031.
