SpaceX has completed its third rocket launch of 2020 and the most recent booster to launch safely returned to Port Canaveral on Saturday after an exceptionally hard drone ship landing.

Falcon 9 booster (first stage) B1051 lifted off for the third time on January 29th, following up two prior orbital-class missions by placing SpaceX’s fourth batch of 60 Starlink satellites into low Earth orbit (LEO). B1051 debuted on March 2nd, 2019 when it became the first Falcon 9 rocket to launch SpaceX’s next-generation Crew Dragon spacecraft, successfully sending the vehicle on its way to what would end up being a flawless rendezvous with the International Space Station (ISS). Less than four months later, B1051 completed its second mission, this time lifting off from SpaceX’s Vandenberg Air Force Base (VAFB), California facilities before landing in zero-visibility fog conditions just a thousand feet from the pad.

Compared to some of the higher-energy geostationary (high orbit) launches SpaceX often performs, B1051’s two prior launches allowed for relatively gentle reentries and landings. On January 29th, 2020, after sending SpaceX’s 3rd batch of upgraded Starlink v1.0 satellites (Starlink V1 L3) on their way to space, the Falcon 9 booster experienced the hardest successful landing seen after a SpaceX launch in quite some time.

With Starlink V1 L3 complete, SpaceX has officially launched an incredible 120 satellites weighing some 32 metric tons (70,500 lb) in a single month – 22 days, to be precise. If everything goes as planned, those two monthly Starlink launches should become SpaceX’s average over the rest of 2020, necessary to satisfy the company’s goal of completing 20-24 Starlink launches this year alone. If SpaceX replicates its January successes this month, the company’s Starlink constellation – already ~230 satellites strong – may even be ready to start serving internet to customers in the northern US and Canada as early as March 2020, less than two months from now.

Meanwhile, the mission marked SpaceX’s second Falcon 9 landing and recovery of the new year, as well as the sixth time an orbital-class SpaceX booster has completed three launches. SpaceX continues to push the envelope of reusable rocketry ever since it debuted Falcon 9’s Block 5 upgrade in May 2018.

Designed to enable no less than 10 launches per booster with minimal refurbishment in between, SpaceX’s Block 5 reusability milestones have gotten much closer together ever since the company began dedicated Starlink launches, reusing a payload fairing for the first time and launching two Falcon 9 boosters for the fourth time in just the last two and a half months. In fact, SpaceX already has plans to launch Falcon 9 booster B1048 for the fifth time – another major reusability first – as early as the next 4-5 weeks.

Hard landing; tough rocket

Starlink V1 L3’s launch followed a trajectory almost exactly identical to the two V1 missions that preceded it in November 2019 and January 2020 and Falcon 9 B1051 ignited its central Merlin 1D engine for the last time around eight minutes after liftoff. Twenty seconds or so later, the Falcon 9 booster rapidly shut down its landing engine, visibly falling several feet onto the deck of drone ship Of Course I Still Love You (OCISLY).

The results of that unintentionally hard landing are extremely apparent in photos taken of the same booster after its first (March 2019) and third (Jan 2020) landings on drone ship OCISLY, compared above. Taken from almost identical perspectives as the drone ship passed through the mouth of Port Canaveral, the difference in the booster’s height and stance are hard to miss, with B1051’s engine bells and the black ‘belt’ of its heat-shielded engine section clearly sitting several feet lower after Starlink V1 L3.

While subtle, the most important difference is near the tips of each visible landing leg’s telescoping boom, visible in the form of a final, smaller cylinder on the left (earlier) image. On the right, that cylinder has effectively disappeared. This is actually an intentional feature of Falcon 9’s landing leg design: known as a ‘crush core’, the tip of each leg boom holds a roughly 1m (3ft) long cylinder of aluminum honeycomb, optimized to lose structural integrity (crush) only after a specific amount of force is applied. In essence, those crush cores serve as dead-simple, single-use shock absorbers that can be reused as long as a given booster’s landing is gentle enough.

B1051’s third landing was definitely not gentle enough, but it appears that the booster’s rough fall onto the drone ship’s deck was just within the safety margins those crush cores provide. Why B1051 fell onto the deck is unclear, potentially caused by the drone being at the bottom of a swell or a last-second anomaly with the booster’s landing engine. Thankfully, regardless of the cause of the anomaly, B1051’s crush cores can be quite easily replaced, meaning that the booster can remain operational as long as its hard landing didn’t cause any less-visible damage or stress elsewhere on the rocket.

In short, SpaceX smart design decisions very likely allowed a part worth just a few thousand dollars to save a Falcon 9 booster worth tens of millions of dollars from the scrap heap. With a little luck, B1051 should have at least several more launches in its future before entering retirement.

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

By

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 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.
