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.

Tesla gives the Roadster an official “Go for launch” demonstration date
Tesla teased an October 1 Roadster reveal, reviving years of delayed SpaceX thruster hover promises.
Tesla teased an October 1 event date for its next generation Roadster, posting an image on X Saturday that shows the car lit up like it is sitting on a launch pad, with the date “10.01” stamped across the bottom and the caption “Go for launch.” A countdown clock on Tesla’s Roadster order page now points to the same date, which falls on a Thursday. The company has not said where the event will happen or whether it will be streamed at the moment. Stay with us @Teslarati for live updates.

Tesla has since sent formal invitations to reservation holders confirming the event will take place in Waco, Texas, about 90 minutes north of its Austin headquarters, based on a digital ticket shared on X by Sawyer Merritt. Tesla did not name the exact venue, though Waco sits close to SpaceX’s McGregor, Texas, rocket test site, previously reported as the planned location for a Roadster thruster demonstration. The invite sets the reveal for 8:30 p.m. Eastern on October 1, requires RSVPs by midnight on September 16, and limits entry to guests 21 and older. Invitations are non-transferable.
The tease follows nine years of a project defined by unimaginable specs along with slipped dates. Musk first showed the second generation Roadster in November 2017 as a surprise reveal at the end of the Tesla Semi event, promising a 0 to 60 mph time under two seconds, a top speed above 250 mph, 620 miles of range from a 200 kWh battery, and production starting in 2020. At last November’s shareholder meeting, Musk set an April 1 demo date and joked the choice gave him “deniability” if it slipped again, which it did, moving first to late April, then to “a month or so,” then to August.
Tesla Roadster SpaceX Package’s 1.1-second 0-60 mph launch visualized in concept video
Whatever Tesla shows on October 1 is expected to center on the SpaceX developed thruster package Musk has described since 2018. Internally code named A71, a nod to the Lockheed SR-71 Blackbird, the system reportedly uses cold gas thrusters fed by a composite overwrapped pressure vessel, the same tank design SpaceX uses on Falcon 9. Musk has said a thruster equipped Roadster could hit 60 mph in about 1.1 seconds under roughly 2.75 g of launch force, well past the 1.9 second figure quoted for the standard car. That version reportedly will not be street legal and has reportedly been discussed as a limited run sold through a track only program.
The standard Roadster is still expected to carry the original $200,000 base price and $250,000 Founders Series tier, both set when Tesla opened $50,000 and $250,000 reservations in 2017. Tesla VP of Vehicle Engineering Lars Moravy has confirmed production will happen at Gigafactory Texas, with Musk targeting 2027 or 2028, 12 to 18 months after whatever the company demonstrates next month.
Tesla is planning to roll out some pretty significant safety and accident avoidance features with Full Self-Driving version 15, which will be the next major FSD deployment from the company.
Tesla AI lead Ashok Elluswamy used a near-miss this week to preview what the company says is the next leap in Full Self-Driving.
In response to a driver whose car had swerved away from another vehicle pulling out of a parking lot, Elluswamy wrote that he was glad the owner was safe and that “even earlier prediction of hazards, even faster reaction time and overall significantly better safety and collision avoidance” would arrive with FSD v15.
Glad you are safe. Even earlier prediction of hazards, even faster reaction time and overall significantly better safety and collision avoidance coming as part of the next big upgrade (v15).

The comment landed as Tesla continues to treat software as the primary safety upgrade path. v15 is described internally as a larger architectural step, with a much bigger neural network and tighter coupling between prediction and control.
The company has already begun using early v15 software in some robotaxi operations while rolling out safety features such as Automatic Collision Evasion into current customer cars, allowing the driving stack to intervene even when the driver is in manual control.
Tesla is rolling out a new FSD version with a massive safety addition
Tesla’s published telemetry is the backbone of its safety argument. In recent North American Vehicle Safety Report data, vehicles with FSD (Supervised) engaged traveled roughly 5.1 million to 5.7 million miles between major collisions, defined as airbag-deployment events.
Tesla’s estimate of the U.S. average over the same period is about 699,000 miles per comparable crash. That is the comparison Tesla often frames as roughly seven times fewer major collisions.
A tighter comparison uses the same Tesla fleet. Cars driven manually with active safety features such as automatic emergency braking still recorded a major collision about every 2.1 million miles. Against that baseline, FSD’s advantage shrinks to roughly 2.4 to 2.7 times fewer severe crashes, which independent researchers argue is the more apples-to-apples figure.
European data released in 2026 pointed in the same direction: Tesla reported FSD as 3.5 times safer than manual driving in the Netherlands and 4.1 times fewer collisions than manually driven Teslas with active safety across more than 100 million kilometers in five approved countries.
Those numbers do not settle every debate. NHTSA’s Standing General Order still shows Tesla accounting for the large majority of U.S. Level 2 driver-assist crash reports, in part because the fleet logs far more assisted miles than rivals. Critics also note that Tesla’s “U.S. average” mixes crash definitions and driving mix.
Even so, Tesla’s own same-car comparisons, plus lower rates of automatic emergency braking and harsh maneuvers when FSD is engaged, are the evidence Elluswamy is pointing to when he says v15 will push prediction and collision avoidance further. The claim is not that software already eliminates risk. It is that each major version is meant to widen the gap between the system and an unaided human driver.
Cybertruck
Tesla’s most delayed Cybertruck feature is finally here
Tesla finally links Cybertruck Powershare with Powerwall 3 for extended home backup after years overdue.
Tesla’s Cybertruck can now pair with a Powerwall 3 to keep a house running longer during an outage, a feature the company first promised when the truck launched in November 2023.
The official Cybertruck account posted the update on X Thursday: “Powerwall 3 & I can now power your house together. This extends your home backup by over 3 days, equivalent to 9 additional Powerwalls,” Cybertruck lead engineer Wes Morrill confirmed the rollout separately, calling it the first time a vehicle and a home battery have worked together this way. Powerwall 2 and Powerwall+ compatibility is still coming later this year, per both the Cybertruck account and Morrill.

Powershare itself is not new. Tesla enabled the version that lets Cybertruck power tools, appliances or another EV through its bed outlets when the truck launched in 2023. Home backup through a Powershare Gateway and Universal Wall Connector arrived in 2024, and Tesla extended that support to homes with solar the following year. What has been missing until now is Powershare working alongside an existing Powerwall, instead of functioning as a separate backup source competing for the same job.
The pairing matters because a single Powerwall home battery typically covers a home for about a day, less if usage is heavy or the outage stretches into a heat wave or freeze. A second Powerwall for more backup storage costs several thousand dollars installed. A Cybertruck instead uses a battery the owner already has, one large enough here to add roughly three more days of backup without mounting another unit or booking an installer visit. For households in wildfire, hurricane or winter storm regions where outages run past a day, that keeps the refrigerator and medical equipment running instead of shutting down.
The company told owners in October 2024 that Powerwall integration was coming sometime in 2025. That date passed, and in December 2025 Tesla pushed the target to mid-2026, with Morrill explaining at the time that two grid-forming devices need to negotiate which one manages a home during an outage, and that certifying the process across multiple generations of Powerwall took longer than expected.
For owners who bought Powershare hardware expecting it to work with whatever battery setup they already had, Thursday’s update closes a gap that has shown up repeatedly in owner complaints since Cybertruck deliveries began. Tesla has also rolled out a separate Powershare grid support program in Texas, letting Cybertrucks send power back to the grid during high demand events, so the truck’s role in a home’s energy setup keeps expanding even as individual pieces of it arrive later than promised.
