Four years after Elon Musk revealed “aspirational” plans to launch Starships to Mars in 2022, the SpaceX CEO now believes that 2024 is a more accurate target.

For SpaceX, that two-year ‘delay’ is more impressive than anything given that the company practically restarted Starship development from scratch a year after Musk set the 2022 target. In late 2018, after more than two years of work developing a Starship (then BFR) built out of carbon fiber composites, the CEO revealed that the company was going to completely redesign the rocket to use steel for all major structures.

Two and a half years after that decision, SpaceX has built a vast Starship factory capable of building at least one ship per month, cumulatively fired dozens of full-scale Raptor engines for more than 30,000+ seconds, flown eight full-scale prototypes, and recovered the first full-size Starship in one piece after a high-altitude launch and bellyflop-style descent and landing.

It doesn’t come as a huge surprise that Starship probably wont be attempting any Mars launches in 2022. Had SpaceX not had to return to the drawing board in 2018, Musk may well have been able to achieve that 2022 goal, but wholly redesigning Starship with steel almost certainly delayed development by at least a year. For interplanetary launches, the most efficient trajectories – those that allow a rocket to maximize payload capacity – are only open for several weeks every ~25 months. That means that a rocket that’s one year behind a Mars launch window will still have to wait more than two years for the next launch opportunity.

In Starship’s case, even if SpaceX were ready for its first Mars cargo missions in 2023, it would need to wait until September or October 2024. That’s far from out of the question but three full years will arguably give SpaceX a good amount of time to both ensure that Starship is technically ready and reliable enough to land on Mars while also determining – and likely designing and building – the cargo those first Starships will carry.

SpaceX could also launch the first one or several Mars-bound Starships with an absolute minimum payload under the assumption that success will require several failures, in which case the company would have until 2026 to develop a system capable of finding and gathering Martian ice, processing it into cryogenic liquid oxygen and methane, and storing that propellant for months or even years. Without that complex system of in-situ resource utilization (ISRU), Starship will never be able to leave Mars, turning initial crewed missions into one-way trips.

In the meantime, while SpaceX has successfully proven that Starship’s exotic skydiver-style landing is viable on planets with atmospheres, orbital Starship flight tests will likely pose just as many challenges. Starship will have the largest heat shield of any spacecraft ever built, while that heat shield will also be the first non-ablative shield ever developed by SpaceX. Even if Starship aces reentries from low Earth orbit (LEO), reentries from geostationary, lunar, or Mars transfer orbits are all multiple times more stressful, requiring still more testing to ensure that its ceramic heat shield and steel hull can withstand interplanetary velocity reentries.

SpaceX will also have to develop unprecedented thermal management solutions to keep hundreds of tons of cryogenic liquid propellant at the right temperatures for weeks, months, or even years in orbit, deep space, and on the surfaces of other moons and planets. This is all to say that SpaceX has its work cut out for it as it approaches the dawn of orbital Starship flight tests and has to tackle a number of daunting technical challenges it might end up being the first to solve. But, as SpaceX always has, it will devour each problem piece by piece until Starship is exactly as capable and revolutionary as the company and its CEO have long promised – if a bit behind schedule.

Google just picked SpaceX for its first step into orbital AI

Google will launch its first Project Suncatcher AI satellite on SpaceX’s Transporter-18 rideshare next week.

Published

Google is about to put its own AI chips into orbit for the first time, and it is paying SpaceX to get them there.

The company said Thursday that the first in-orbit test of Project Suncatcher, its research effort to find out whether space can host large-scale AI computing, will fly next week on SpaceX’s Transporter-18 rideshare mission.

The satellite, called MVP, is about the size of a refrigerator and carries four of Google’s Tensor Processing Units, the same chips Google runs in its ground data centers. Google originally planned to launch two custom satellites in 2027, but chose to move faster by integrating its chips into a satellite.

MVP’s solar panels supply about one kilowatt of power, and Google will run Gemini models on the TPUs only in bursts of roughly 15 minutes before the chips shut down so the radiators can shed heat. In a blog post, Google said its Trillium TPUs survived vibration testing that mimicked sustained launch loads of up to 10g, with individual components seeing 50 to 100g, and handled a radiation dose greater than a five year mission would deliver.

SpaceX and Google mull massive partnership on Musk’s orbital data dream: report

Next week’s flight, slated for October 1, follows a relationship that became public in May, when Teslarati reported that Google was in talks with SpaceX for a launch deal tied to orbital data centers. Google also holds a stake of roughly 6% in SpaceX.

The two companies are chasing the same idea from very different starting points. SpaceX’s own orbital compute program is built around the AI1 satellite, a roughly 70 meter structure derived from Starlink V3 hardware that is designed for 150 kW of peak compute, about 150 times the power MVP will draw. Elon Musk has brushed off concerns about crowding orbit with those satellites, and SpaceX is building its Gigasat factory in Bastrop, Texas, to produce them, targeting an annualized rate of about 1 GW of space compute by the end of 2027.

Musk also posted on X on Thursday that “the amount of compute in space will obviously round up to 100% of all compute.”

Google has been more cautious in public. Its research estimates that launch prices need to fall below about $200 per kilogram before an orbital data center can compete with a ground facility on energy cost, a threshold the company believes could be reached around the mid 2030s. The Suncatcher team has said it expects the effort to remain a project rather than a product for years, which leaves the first real test of its hardware riding on a rocket from the company with the most aggressive timeline in the field.

Tesla Cybercab gets initial tie-in to localized, in-house cathode plant

Published

Tesla has taken another concrete step toward owning its battery supply chain, and it’s doing so with what is perhaps the most important vehicle in its short-but-storied history.

On September 23, Tesla announced that it has officially built the first Cybercab with cathode material produced in-house at the company’s first cathode plant in the U.S., and the first in the U.S. overall.

Active cathode material is the most expensive piece of a lithium-ion battery cell, and it often accounts for more than a third of cell cost. For years, the industry sourced a majority of it from Asia, but Tesla’s decision to make it in the United States bodes well for the Cybercab project. This is the latest chapter in Tesla’s vertical integration strategy, which began in public at Battery Day in 2020.

At the Battery Day Event, Elon Musk said the company would build a North American cathode plant and overhaul the process to cut costs and waste, while also making some of the most powerful and long-lasting cells in the industry.

The Austin facility took years to appear. Tesla filed permits for “Project Cathode” in 2022 on land near Giga Texas. By mid-2022, the building frame was up and Tesla later invested hundreds of millions of dollars as part of a larger expansion of the Giga Texas plant. The company stated it was operating the first large-scale cathode production facility in North America to supplement 4680 cell production.

One month later, that material reached a finished Cybercab.

The timing of this breakthrough is monumental for the Cybercab program. As Tesla officially launched the first Cybercab rides to the public earlier this month, production of the ride-hailing-geared vehicle is moving forward on the planned S-curve that CEO Elon Musk told everyone to expect.

Nevertheless, packs of Cybercab units have been spotted throughout the United States, in an effort to potentially activate the fleet as soon as the company gains regulatory approval in various geographic areas.

On top of that, Tesla owning the cathode step and pairing it with its own in-house lithium from the Gulf Coast refinery shortens the supply chain that once stretched thousands of miles and subjects every pack to fewer external price shocks and geopolitical risks.

Tesla is not yet independent of all of its foreign suppliers, as some precursor metals come from mines and chemical plants. But the first in-house cathode Cybercab shows the company is closing the most expensive and most concentrated gap in its battery production efforts. For a vehicle like Cybercab to operate at a high utilization within the Robotaxi network, that control over cost is so crucial.

It is arguably as important as the software that drives it.

Tesla is set to inaugurate its dedicated Semi factory in Sparks, Nevada, this evening, but drone footage has already started to show who is expected on the handover stage.

Zanegler, a drone operator who regularly documents Tesla Semi operations in Nevada, filmed a row of new-generation Semi units parked outside of the plant with customer branding applied. The liveries visible in the video include companies like PepsiCo, U.S. Foods, Einride, DHL, WattEV, and others that have committed to utilizing Tesla’s Class 8 electric truck in their fleets.

Several of those company names already sit within Tesla’s public ordering book, including PepsiCo, which has been the program’s primary anchor customer since the first Semi deliveries in December 2022. PepsiCo now runs dozens of Tesla Semi units in daily service, with drivers completing regional routes.

Einride placed a 500-unit order in August, which was, at the time, the largest single Semi commitment. First deployments of their Semi units are planned for this month and will eventually span across California, Texas, New Jersey, Illinois, and Georgia. Meanwhile, IMC Logistics announced a 50-truck California order this week.

Tesla Semi lands the biggest electric truck deal in U.S. history

Other names, like LTS, OK Produce, and HMD, have not been widely confirmed as firm buyers, but their presence on the lot is perhaps the clearest signal that Tesla intends to expand on that list this evening at the event.

Tesla first unveiled the Semi back in 2017 with a 2019 production target.

Limited pilot builds reached PepsiCo in late 2022, and high-volume production began at the new 1.7-million-square-foot plant that sits logically positioned next to Tesla’s Gigafactory Nevada. Tesla Semi program director Dan Priestley has said that Tesla expects to build “many thousands” of Semi units this year, but as with every Tesla release, there have been set expectations of an S-curve ramp.

Outside estimates still put 2026 deliveries in the 5,000-to-15,000 range, but it will ultimately depend on Tesla’s readiness to put those units out, as well as how smoothly production is moving internally.

Tesla’s Semi Rollout event is set to start tonight at the Sparks factory, and it will be livestreamed on X starting at 6 p.m. PDT / 9 p.m. ET.
