SpaceX Plans First Mars Missions Within Two Years, Crew Flights by 2028

SpaceX aims to initiate Mars expeditions as soon as two years from now, starting with uncrewed landings on the Red Planet. If these prove successful, CEO Elon Musk envisions sending astronauts as early as 2028.

Elon Musk revealed this timeline in a message on X (previously Twitter) on September 7, outlining a bold vision for exploring other worlds. He noted that the orbital alignment of Earth and Mars occurs every 26 months, which is critical for mission schedules.

Uncrewed Landings to Validate Technology

The first missions will prioritize demonstrating Starship’s capability to safely touch down on Mars. “These flights will be uncrewed to verify landing reliability on the Red Planet. Provided those go smoothly, crewed Mars trips will follow within four years,” Musk explained. Early successes could set the stage for regular flights, as SpaceX works toward creating a permanent human settlement on Mars within a few decades.

Musk stressed the significance of this goal, stating that establishing a multiplanetary civilization would greatly enhance humanity’s longevity by spreading our presence beyond Earth.

The first Starships to Mars will launch in 2 years when the next Earth-Mars transfer window opens.

These will be uncrewed to test the reliability of landing intact on Mars. If those landings go well, then the first crewed flights to Mars will be in 4 years.

Starship: A Game-Changing Launch Vehicle

SpaceX’s Starship combines immense power with reusability, featuring two main elements: the Super Heavy booster and the 165-foot tall upper-stage spacecraft, also named Starship. Together, they form a towering 400-foot (0.12 km) rocket, delivering a massive 16.7 million pounds of thrust at liftoff—twice the force generated by NASA’s Space Launch System (SLS), which supports Artemis missions.

Unlike NASA's single-use SLS, Starship is engineered for frequent reuse. SpaceX plans to recover the Super Heavy booster by landing it on the launch platform after each mission, enabling swift inspections and quick turnaround. This innovation aims to reduce launch costs drastically and facilitate regular Mars missions.

Steady Advances Toward Mars

Although not yet fully operational, Starship has completed four successful test flights, each with incremental progress. These launch attempts occurred in April and November 2023, followed by further tests in March and June 2024. Every launch accomplished important milestones, and the forthcoming fifth test flight is set to introduce more complex maneuvers.

This next launch will be SpaceX’s initial effort to land the Super Heavy booster precisely on the launch mount using the tower’s “chopstick” arms—a vital advancement for fast reusability. Musk frequently remarks that Starship guarantees thrilling developments as SpaceX pushes the frontier of space exploration.
