SpaceX details plan to build Mars Base Alpha with reusable Starship rockets
For the first time, SpaceX has teamed up with researchers from NASA and several other US institutions to publicly discuss how it plans to use Starship to build Mars Base Alpha.
Save for a handful of comments spread around the periphery of SpaceX and CEO Elon Musk’s main focus, Starship itself, the company and its executives have almost never specifically discussed how the next-generation fully-reusable rocket will be used to create a permanent human presence on Mars. For the most part, that clear focus on near-term hurdles is hard to fault. Half a century of mostly theoretical analysis has made it abundantly clear that a permanent and sustainable extraterrestrial human outpost is impossible without a radical reduction in the cost of access to space. For decades, NASA has studied and studied and studied slight variations of a plan that would cost hundreds of billions of dollars to send a few astronauts to Mars for a few months at a time.
Put simply, without a revolution in space transport, even a temporary presence on Mars where inhabitants are mostly dependent on imported goods is infeasible unless Mars exploration is made a national or international priority on the order of tens of billions of dollars per year. Over the 80-90 years that spaceflight has been seriously pondered, dozens of groups and papers and studies and space agencies have imagined what that revolution might look like and SpaceX is not unique for proposing a solution to that longstanding problem. However, SpaceX is the first of that long list of contenders to propose a solution and both invest significant resources and put hammer to metal in an attempt to make that vision real.
Two years after SpaceX announced its intention to build that next-generation space transportation system, Musk revealed a radical design change and work on the first steel Starship prototypes began. Three years later, SpaceX has completed nine Starship test flights – four brief hops and five flights above 10 km (6 mi). In 2021 alone, SpaceX completed four of those high-altitude flight tests, recovered a high-altitude prototype intact for the first time, built the first orbital-class ship and booster prototypes, began testing that ship, and is nearly finished the first orbital Starship launch site from scratch. In April, SpaceX also secured a $2.9 billion NASA contract to build a human-rated Moon lander variant of Starship.
Put simply, SpaceX – and now NASA with it – has laid a sturdy foundation upon which Starship will almost certainly be realized. A great deal of work remains but SpaceX has more or less surmounted most of the major technical hurdles that towered over Starship/BFR/ITS just a few years ago. A wealth of Starship ground and flight tests have firmly demonstrated that the rocket’s structures, avionics, Raptor engines, exotic methods of descent and landing, and previously unflown fuel of choice are all ready for orbital flight. From then on, SpaceX will still need to prove out Starship’s massive, ceramic, non-ablative heat shield technology; mature orbital rocket refueling techniques and technologies; and finally operationalize all the above to make the rapid launch, reuse, and refueling of the largest rocket in history routine and mundane – something SpaceX has proven to be more than capable of with Dragon and Falcon.
How, then, will SpaceX proceed to the Red Planet?
Packing for Mars
With the help of coauthors from NASA Ames, SETI, and half a dozen prestigious US universities and institutes, SpaceX has begun to answer exactly that question in a 2021 whitepaper [PDF] submitted for the National Academies’ next Planetary Science and Astrobiology Decadal Survey. While that survey alone could influence NASA as the agency prepares to outline its next decade of space science and determine the ultimate destination of tens of billions of federal dollars, the consequences of which could be immense, SpaceX also used the paper to describe its plans for early missions to Mars in unprecedented detail.
As has always been the plan, SpaceX will begin the process of constructing sustainable cities on Mars with a few (relatively) simple steps. Likely as soon as the mid-2020s, SpaceX will begin launching uncrewed Starships to Mars to both verify the system’s maturity and readiness and “deliver significant quantities of cargo to the surface in advance of human arrival.” Likely leaning on a wide range of robotics, those early missions will help SpaceX characterize local resources, stage supplies, test technologies for long-duration Martian surface ops, and begin developing infrastructure – with a propellant plant likely the most pressing need. None of that is surprising. However, there’s more.
According to the authors, which include several current and former SpaceX engineers, “current SpaceX mission planning [tasks those early uncrewed Starships with delivering] equipment for increased power production, water extraction, LOX/methane production, pre-prepared landing pads, radiation shielding, dust control equipment, exterior shelters for humans and equipment, [and more – all hardware needed to support the first human base.]”
Further, confirming what’s been assumed to be the plan for years, “humans will likely live on [Starships] for the first few years until additional habitats are constructed” and “the first wave of uncrewed Starships can also be relocated and/or repurposed as needed to support the humans on the surface,” serving as “valuable assets for storage, habitation, [scientific laboratories], and a source of refined metal structures and resources.” The paper also states that “SpaceX is aggressively developing Starship to…conduct initial test flights to Mars…as soon as 2022 [or 2024]” and even raises the possibility of SpaceX launching the first Starship(s) to Mars before the rocket’s first lunar mission but then launching a separate lunar mission and landing a different Starship on the Moon while the Marsbound ship or ships are still in transit.
The whitepaper marks the first time that SpaceX (or those familiar with the company’s plans) has properly fleshed out the basics of its first crewed and uncrewed Starship missions to Mars and confirms a great deal of well-informed speculation. Namely, SpaceX appears to intend to pack even the very first Mars-bound ships with supplies. But even if they don’t bring much, the first Martian immigrants – launched in batches of “10-20 people” alongside “100+ metric tons” (~220,000+ lb) of cargo – will reuse all surviving Starships as pre-emplaced habitats, storage tanks, and raw material feedstock. Early cargo will focus on power, water, and propellant production, as well as shelters, radiation shielding, and the construction of prepared landing pads. Unsurprisngly, early residents will likely make the Starships that carry them to Mars their first homes on the surface of the Red Planet, taking advantage of an ~1100m³ (~39,000ft³) pressurized volume already outfitted to keep dozens of people alive and healthy in deep space for months at a time.

Elon Musk hints at “official ceremony” with throwback photo to close Tesla Model S, Model X chapter
Elon Musk promises an official ceremony to mark the end of Tesla Model S and Model X production.
Tesla has officially begun winding down production of the Model S and Model X, sending farewell emails to U.S. customers on March 27 and updating the website to reflect the end of the line. Shoppers visiting Tesla.com now find only a limited set of Model S and Model X inventory units available for purchase, with no option to configure a new factory build. The move formalizes what CEO Elon Musk announced on the company’s Q4 2025 earnings call in January, when he said it was “time to basically bring the Model S and X programs to an end with an honorable discharge.”
Musk posted on X a throwback photo of himself speaking at the Model S production launch in 2012, and noting “We will have an official ceremony to mark the ending of an era. I love those cars.”
The mention of an official ceremony is notable. Tesla has not held a formal farewell event for a vehicle before, and Musk’s wording suggests this will be something deliberate rather than a quiet line shutdown. Given that Musk’s X post shows a photo of him on stage with a microphone in front of an audience at the Fremont factory, it wouldn’t be too far-fetched to expect a closing ceremony to take place at the same location. Perhaps? Whether it becomes a public event, a private gathering for employees, or a livestreamed moment on X remains to be seen.
Custom orders of the Tesla Model S & X have come to an end. All that’s left are some in inventory.

The Model S first went on sale nearly fifteen years ago and was Tesla’s first fully in-house designed vehicle, proving that an electric car could be fast, desirable, and capable of long distance on a single charge. The Model X followed in 2015, turning heads with its unmistakable and distinctive falcon-wing doors, while becoming one of the first all-electric SUVs on the market. Tesla’s two flagship vehicles would ultimately push legacy automakers to take all-electric transportation seriously and help fund development of the more affordable Model 3 and Model Y.
By 2025, however, both models had been reduced to a rounding error in Tesla’s sales figures. Musk was direct about what comes next, stating “We are going to convert that production space to an Optimus factory. It’s part of our overall shift to an autonomous future.”

That shift is already underway. Tesla officially started Optimus Gen 3 production at its Fremont factory in January 2026, with the line targeting a run rate of one million units per year. The Gen 3 robot features 22 degrees of freedom per hand, runs on Tesla’s AI5 chip, and shares the same neural network architecture as Full Self-Driving. A dedicated Optimus factory at Gigafactory Texas is also under construction, with a planned annual capacity of 10 million units. The production lines that once built the Model S and Model X are being converted to support that ramp.
Tesla confirmed it will continue to support existing owners with service, software updates, and parts for as long as people own the vehicles. For buyers still interested in a new example, remaining U.S. inventory is discounted and the window is closing fast.

Elon Musk announces disappointing Tesla Optimus update
In a post on X on March 31, Musk stated that Optimus 3 is mobile but requires some finishing touches before it is ready to be shown to the world. This update comes on the final day of the first quarter, a period when Tesla had previously signaled expectations for a Gen 3 reveal.
Elon Musk announced a disappointing update to the unveiling of Tesla Optimus and its third-generation iteration, missing a timeline it aimed to hit in the first quarter of the year.
Musk has confirmed that the highly anticipated Optimus Gen 3 humanoid robot is already walking around and operational, yet the public unveiling will face a short delay as the company applies final refinements.

The announcement follows reports of Optimus Gen 3 appearing at the Tesla Diner in Los Angeles, where it was observed serving and moving about until sunset. Images and videos shared by observers captured the robot in action, highlighting its progress in real-world mobility.
Tesla had aimed to showcase the production intent version of Optimus Gen 3 during the first quarter of 2026, positioning it as a major step toward factory deployment and eventual commercial availability. Musk has described the robot as featuring advanced capabilities, including highly dexterous hands with significant degrees of freedom, powered by Tesla’s AI systems for complex tasks.
This minor postponement aligns with Tesla’s iterative approach to development. Earlier statements from Musk indicated that Gen 3 would represent the most advanced humanoid robot yet, designed primarily for internal factory use before scaling to external customers.

Production timelines point toward low-volume output starting in the summer of 2026, with volume ramp-up targeted for 2027. The delay underscores the company’s commitment to quality over speed, ensuring the robot meets rigorous standards for safety and performance in practical environments.
Optimus represents a cornerstone of Tesla’s long-term vision beyond electric vehicles. Musk has repeatedly emphasized that successful humanoid robotics could transform industries by addressing labor shortages and enabling new forms of productivity.
Competitors in the space continue to advance their own platforms, yet Tesla’s vertical integration, from custom actuators to end-to-end AI training, positions Optimus as a potential leader. Community reactions on social media range from excitement over visible progress to impatience with shifting timelines, a familiar pattern in Tesla’s innovation journey.
Investors and enthusiasts view Optimus as critical to Tesla’s valuation, potentially surpassing its automotive business in scale. With the robot already demonstrating walking and basic interactions, the finishing touches likely involve software polishing, hardware fine-tuning, and reliability enhancements.
Musk’s update suggests the reveal could arrive in the coming weeks or months, maintaining momentum toward broader deployment.
As Tesla pushes the boundaries of physical artificial intelligence, this latest development keeps Optimus in the spotlight. The company continues to prioritize rapid iteration while delivering on its promises to shareholders and customers. The robotics revolution at Tesla appears closer than ever, promising profound impacts on manufacturing, services, and daily life in the years ahead.

Countdown: America is going back to the Moon and SpaceX holds the key to what comes after
NASA’s Artemis II launches Wednesday, sending humans near the Moon for the first time since 1972.
For the first time since Apollo 17 touched down on the lunar surface in December 1972, the United States is sending humans back toward the Moon. NASA’s Artemis II mission is set to launch as early as this week from Kennedy Space Center in Florida, carrying four astronauts on a 10-day journey around the Moon and back to Earth. It will not land anyone on the surface this time, but it is the first crewed flight in over half a century to travel beyond low Earth orbit, and it sets the stage for Elon Musk’s SpaceX missions to follow.
The mission uses NASA’s Space Launch System rocket and the Orion spacecraft, which will fly around the Moon before splashing down in the Pacific Ocean around April 10. For context, an uncrewed Artemis I flew the same path in 2022, proving the hardware worked. Artemis II now tests it with people aboard.
According to NASA’s official countdown blog, launch preparations are on track with an 80 percent chance of favorable weather. “Hey, let’s go to the moon!” Commander Wiseman told reporters upon arriving at Kennedy Space Center.

Beyond Artemis II lies the lander question, and that is where SpaceX enters directly. In 2021, NASA awarded SpaceX a $2.89 billion contract to develop the Starship Human Landing System, a modified version of Starship designed to ferry astronauts from lunar orbit to the surface. The original plan called for SpaceX to deliver that lander for Artemis III, which was to be the first crewed lunar landing. Timing for Starship development, however, caused NASA to restructure the mission sequence entirely.
Before SpaceX’s Starship Human Landing System (HLS) can put anyone on the Moon, it has to solve a problem no rocket has demonstrated at scale, which is refueling in orbit. Because the Starship HLS requires approximately ten tanker launches worth of propellant loaded into a depot in low Earth orbit before it has enough fuel to reach the lunar surface, SpaceX plans to conduct this refueling process using its upgraded V3 Starship. And until that demonstration flies and succeeds, the Starship moon lander remains a question mark.
SpaceX’s Starship V3 is almost ready and it will change space travel forever
In February 2026, NASA Administrator Jared Isaacman confirmed that Artemis III, now planned for mid-2027, and will instead test lunar landers in low Earth orbit, with the actual landing pushed to Artemis IV that’s targeted for 2028.
Musk responded to earlier criticism of SpaceX’s schedule by posting on X that his company is “moving like lightning compared to the rest of the space industry,” and added that “Starship will end up doing the whole Moon mission.” The contract competition was also reopened in October 2025 by then NASA chief Sean Duffy, who cited Starship’s delays and said the agency needed speed given China’s own stated goal of landing astronauts on the Moon by 2030.
They won’t. SpaceX is moving like lightning compared to the rest of the space industry.
Moreover, Starship will end up doing the whole Moon mission. Mark my words.

Artemis came from the first Trump administration’s 2017 Space Policy Directive 1, which directed NASA to return humans to the Moon. The program picked up pace through the 2020s, with the Orion spacecraft and SLS taking years to develop at enormous costs. SpaceX entered the picture in 2021 as the chosen lander contractor, tying the commercial space sector into what had historically been an all government undertaking.
Whether SpaceX’s Starship ultimately carries astronauts to the lunar surface or shares that role with Blue Origin’s competing lander, this week’s Artemis II launch is the necessary first step. Getting four humans to the Moon’s vicinity and back safely is the proof of concept everything else depends on.
