BTA2023 For years, Elon Musk promised Mars. Humans by 2026. A new civilisation on the Red Planet. Now, the SpaceX founder is reordering priorities — and the Moon has jumped to the front of the line.
In a post on X over the weekend, Musk said SpaceX is shifting its near-term focus from Mars exploration to building a “self-growing city” on the Moon, citing faster launch cycles and the ability to iterate more quickly.
The announcement marks a significant recalibration of Musk’s long-standing interplanetary ambitions and comes amid broader consolidation across his technology empire.
Why the Moon is now the priority
According to Musk, the decision is driven by orbital mechanics and speed.
“It is only possible to travel to Mars when the planets align every 26 months,” he wrote, noting that the journey takes roughly six months. By contrast, missions to the Moon can launch every 10 days, with a travel time of about two days.
“That means we can iterate much faster to complete a Moon city than a Mars city,” Musk said.
The faster cycle, he argued, makes the Moon a more practical testing ground for large-scale off-Earth infrastructure, manufacturing and permanent human settlement.
A sharp turn from earlier Mars timelines
The shift contrasts sharply with Musk’s earlier confidence about Mars.
In 2020, the SpaceX CEO said he believed humans could land on Mars by 2026, suggesting an uncrewed mission could happen even sooner.
“If we get lucky, maybe four years,” Musk said at the time, outlining plans to send an initial vehicle within two years.
However, SpaceX’s history of pushing back timelines — often due to technical complexity and regulatory hurdles — has repeatedly stretched those ambitions.
Mars is delayed, not abandoned
Despite the pivot, Musk insists Mars remains central to SpaceX’s long-term vision.
In his latest comments, he said the company would begin serious Mars city development in five to seven years, framing the Moon as a stepping stone rather than a replacement.
“But the overriding priority is securing the future of civilization,” Musk wrote. “And the Moon is faster.”
He added that SpaceX is planning self-growing lunar bases and factories, alongside the eventual goal of establishing “an entire civilization on Mars.”
The announcement comes amid Musk’s broader tech consolidation
The lunar focus also lands at a moment of heightened activity across Musk’s businesses.
Last week, Musk announced that SpaceX had acquired xAI, the artificial intelligence company behind the Grok chatbot. XAI, in turn, purchased the social media platform X in March 2025.
Musk described the combined structure as creating “the most ambitious, vertically-integrated innovation engine on (and off) Earth,” integrating AI, rockets, satellite internet, direct-to-device communications and real-time information platforms.
The consolidation underscores Musk’s push to align space exploration, artificial intelligence and communications infrastructure under a unified strategic vision.
A slower path to Mars, a faster route off Earth
While Mars has long captured Musk’s imagination — and public attention — the Moon’s proximity, logistics and rapid launch cadence appear to have won the near-term battle.
For SpaceX, the Moon is no longer just a waypoint. It is now the proving ground for humanity’s first attempt at building a permanent, expanding city beyond Earth.
