SpaceX to Send Starships to Mars

Elon Musk has provided a radically ambitious timeline to make humanity a multi-planetary species.

SpaceX’s ambitious plan to begin Mars missions with its Starship megarocket is set to take off within the next two years, according to the company’s founder and CEO, Elon Musk.

Musk revealed the ambitious timelines in a recent post on the social media platform X, outlining a phased approach to colonizing the Red Planet.

In his announcement, Musk stated, “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.” He further emphasized the critical timing of these launches, as Earth and Mars align favorably for interplanetary missions every 26 months.

Looking beyond these initial steps, Musk envisions a rapidly increasing flight rate that will lay the foundation for a self-sustaining Martian city within the next two decades. “Being multiplanetary will vastly increase the probable lifespan of consciousness, as we will no longer have all our eggs, literally and metabolically, on one planet,” Musk added.

The Starship system features a two-part configuration: the Super Heavy first-stage booster and the 165-foot-tall Starship upper-stage spacecraft. Combined, they create the most formidable rocket ever built, standing approximately 400 feet tall and generating 16.7 million pounds of thrust at liftoff—almost double that of NASA’s Space Launch System used in the Artemis moon program.

Unlike its NASA counterpart, which is expendable, Starship is designed for full and rapid reusability. SpaceX plans to land the Super Heavy booster directly back on the launch mount after each mission, facilitating swift inspections, refurbishments, and subsequent relaunches. This innovative approach not only showcases SpaceX’s commitment to sustainability but also significantly reduces the costs associated with space travel.

Currently, Starship is in the testing phase, having completed four missions as of June this year. Each mission has seen improvements in performance, meeting all major objectives during the latest flight. Preparations for a fifth flight are underway, with recent tests on both the Super Heavy booster and the Starship craft intended for the upcoming mission.

The next flight promises to be particularly thrilling, featuring the first attempt to land the Super Heavy booster using the launch tower’s “chopstick” arms—a maneuver that, if successful, will mark a significant achievement in spaceflight technology. As Musk often remarks, “excitement is guaranteed” when it comes to Starship flights, pointing to the potential of these missions to bring humanity closer than ever to becoming a multiplanetary species.

Musk’s Proposed timeline to Becoming a Multiplanetary Species

2 years→ First uncrewed Starships launch to Mars during the next Earth-Mars transfer window to test landing reliability.

4 years→ First crewed flights to Mars, if the uncrewed landings are successful.

20 years→ Goal of building a self-sustaining city on Mars, with an exponentially growing flight rate.

Long-term→ Becoming a multiplanetary species to increase the probable lifespan of consciousness by reducing dependence on a single planet.
