SpaceX’s Mars page says Starship cargo flights to the Martian surface are planned no earlier than 2028. That wording describes an ambition and an earliest planned date, not a successful landing or a guaranteed launch schedule. SpaceX Mars plans
The company describes Starship as a fully reusable system designed for transporting substantial cargo. Its stated orbital payload capability and its Mars ambitions are different claims: a design figure for carrying cargo to orbit is not a record of mass delivered to the Martian surface.
SpaceX also describes the use of liquid methane and oxygen as propellants and outlines a longer-term vision for a self-sufficient city on Mars. Such material explains the company’s intended direction. It should not be presented as an independently verified assessment that the necessary missions, infrastructure or settlement already exist.
A mission’s proposal, launch, interplanetary travel and landing are separate milestones. Each would require dated mission records to establish completion. The published planning page supports reporting what SpaceX says it intends to do, while leaving the outcome conditional on development and future operations.
Archive note: the earlier completed Mars cargo mission, payload delivery, landing details and attributed remarks were not substantiated.
