SpaceX has completed its 40th Falcon 9 launch of 2022, delivering a new batch of Starlink satellites and Boeing demonstration satellite into orbit.

Right on schedule, Falcon 9 lifted off from SpaceX’s Cape Canaveral Space Force Station (CCSFS) LC-40 pad at 10:09 pm EDT, Sunday, September 4th. The rocket’s reused booster and fairing and new upper stage performed as expected, continuing Falcon 9’s unprecedented streak of 149 successful launches. Flying for the seventh time overall, former Falcon Heavy booster B1052 performed flawlessly after a quick 31-day turnaround and touched down on SpaceX drone ship Just Read The Instructions’ (JRTI) deck several hundred miles downrange less than nine minutes after liftoff.

Flying for the fourth and fifth times, the Starlink 4-20 mission’s Falcon 9 fairing halves also worked as expected on ascent. SpaceX does not discuss fairing recovery but both halves likely deployed parafoils after reenter Earth’s atmosphere and gently splashed down in the Atlantic Ocean. SpaceX support ship Doug will eventually fish them out of the water for reuse.

Not merely a Starlink mission, Starlink 4-20 was SpaceX’s sixth Starlink rideshare. Sitting atop the stack of 51 Starlink V1.5 satellites was an experimental spacecraft built by Spaceflight Inc. Known as Sherpa-LTC2, Spaceflight and partner Astro Digital turned the orbital transfer vehicle (space tug) into a satellite for customer Boeing. The purpose: carry and test a prototype communications payload built by Astro Digital and designed to verify new V-band communications technologies for a planned constellation of Boeing satellites in Low Earth Orbit (LEO).

The US Federal Communications Commission (FCC) approved Boeing’s plans for a 147-satellite V-band constellation in November 2021. It’s unclear what the purpose of the constellation would be or if Boeing already has customers or partners lined up. The prototype spacecraft built by Spaceflight and Astro Digital – known as Varuna in recent FCC filings – will be crucial for determining the constellation’s future. Boeing wants to use a swath of spectrum known as the V-band that has a higher frequency than the Ku and Ka bands commonly used by most other communications satellites. A higher frequency could mean higher connection speeds and more available bandwidth, but V-band radio waves tend to struggle to pierce through rain and other adverse weather conditions.

Varuna should help Boeing fully determine whether that interference is a showstopper or something that can be managed. Boeing applied for an FCC license for its V-band constellation in 2017. It’s unclear whether a lack of interest on Boeing’s part or problems with the application caused the process to take as long as it did.

Varuna was successfully deployed from Falcon 9 a bit less than 50 minutes later in a mostly circular orbit 316 kilometers (196 mi) above Earth’s surface. Outfitted with a propulsion system designed by startup Benchmark Space, Sherpa-LTC2 is meant to eventually raise itself into an operational orbit around 1050 kilometers (~650 mi), where the V-band payload can be tested at the same altitude as Boeing’s planned constellation.

20 minutes after Varuna’s deployment, Falcon 9’s upper stage – spinning end over end – released all 51 Starlink satellites at once, completing the payload portion of the mission. As always, the upper stage will likely perform a deorbit burn within a few hours of liftoff and should reenter Earth’s atmosphere not long after, ensuring that the only space debris produced by the mission is the Varuna deployment mechanism and a set of four benign Starlink ‘tensioning rods’ that should reenter in about two months.

Starlink 4-20 was SpaceX’s 40th launch of 2022 and 50th launch in 12 months. According to Next Spaceflight, the company has plans for at least two more Starlink launches within the next eight days. Starlink 4-2, another rideshare mission, is scheduled no earlier than September 10th, while Starlink 4-34 could launch on September 12th.

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

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 leaks Semi customers ahead of handover event

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.
