SpaceX putting the finishing touches on Starship’s orbital launch pad

SpaceX appears to have begun tying up a number of loose ends at Starship’s first orbital launch site, potentially setting the stage for major rocket testing CEO Elon Musk has stated could begin next month.

The list of tasks started or completed in just the last week or two is significant and each one is singularly focused on similar goals: pave the way for SpaceX to finish testing the first orbital-class Starship and Super Heavy booster and prepare for the first orbital launch attempt of the largest rocket ever built. While SpaceX’s progress towards those goals over the last several months has been decidedly slow relative to the pace of similar work completed in the very recent past, the nominal timeline Musk recently sketched out suggests that things could once again start to happen at a dizzying rate.

Launch Tower

Kicking off a jam-packed two weeks of minor to major finishing touches, SpaceX rigged Starbase orbital launch tower’s rocket-catching arms to a system of pulleys, and ‘drawworks’ in a process known as “reeving.” Thousands of feet of rope were first threaded from up, down, and through the ~145m (~440 ft) tower to act as a temporary guide for the next step. Once fully rigged, anchored, and attached to the start of the steel cable actually meant to operate the system, the tower’s ‘drawworks’ was activated for the first time to reel in the guide rope – simultaneously installing the steel cable. By November 9th, the process was more or less complete, leaving the steel cable firmly attached to the tower’s giant rocket-catching arms and able to carry their significant weight.

SpaceX hasn’t quite finished installing those arms and does not appear to have picked up the slack in the cable that will eventually lift them up and down the tower, but the arm assembly’s first real move is likely just a few weeks away. Notably, a bit of scaffolding around the tower’s ‘legs’ still needs to be removed before the catch arms can freely roll up and down rails welded to their exteriors. SpaceX will also need to complete shakedown testing of the arms themselves, ensuring that the massive structures’ hydraulic, electrical, and mechanical systems are all working properly.

In the near future, those arms will be used to grab, lift, and install Super Heavy boosters and stack Starships on top of them, while SpaceX also hopes to eventually use them to catch boosters and ships out of mid-air. At least for the former role, a separate arm visible about halfway up the tower in the photo above will also be crucial. Known as the tower’s Starship quick-disconnect (QD) arm or claw, SpaceX has also made significant progress on the structure, practically completing it in the last few days.

Designed to fuel Starship and stabilize the top of Super Heavy with its claw, the Starship ‘QD arm’ is also able to swing left and right both to quickly back away during launches and to make room for the catch arms during rocket catches and ship/booster stacking operations. Last week, SpaceX technicians finished plumbing the arm, which requires thousands of feet of insulated steel tubes to connect to the pad’s propellant tanks. This week, on November 23rd, SpaceX installed the last major component of the arm – the actual quick disconnect (QD) mechanism that will connect to Starship to supply power, communications, and propellant.

A few small actuators likely still need to be installed and the QD mechanism itself will have to be fully connected to pad systems but the QD arm now appears to be more or less complete and should soon be ready to fuel Starships installed on top of Super Heavy boosters.

Launch Mount

Last but not least, SpaceX performed multiple tests of the pad’s ‘orbital launch mount’ – the giant, steel structure that will support Super Heavy, hold the booster down during testing and before liftoff, and supply it with thousands of tons of propellant. On November 21st, SpaceX completed the first of those tests, seemingly venting an unknown gas out of the mount. More likely than not, it was the first simultaneous test of all 20 of the mounts Raptor Boost engine gas supplies, which – having no need to reignite in flight – will rely on ground gas supplies for ignition. Each of Super Heavy’s 20 outer Raptor engines has a small umbilical and quick disconnect mechanism, resulting in what is likely the most mechanically complex rocket launch mount ever built.

On November 22nd, the orbital launch mount’s booster quick disconnect panel actuated for the first time, showing off the first glimpse of how it will move forward to connect to Super Heavy after a booster is installed on the mount. To prevent its sensitive components from being practically incinerated each launch, the mount’s QD panel will also need to rapidly move away from Super Heavy just before liftoff.

Aside from simply avoiding direct impingement from the several-thousand-degree plume created by 29-33 Raptor engines at full thrust, that movement will also tie into some kind of hood, seamlessly actuating hatches that will close to truly protect the device. That hood was itself spotted for the first time on November 21st and will likely be installed on the launch mount and over the naked QD mechanism in the very near future.

Finally, over the last week or so, SpaceX has begun installing a number of new pipes on and around the launch mount, likely assembling a water deluge system that will help manage the extreme thermal and acoustic environment created by the most powerful rocket in history shortly before and after liftoff. When activated, a spray bar circling the mount’s full interior circumference will likely unleash several tons of water per second in a giant artificial waterfall, hopefully preventing Super Heavy from damaging itself with the sheer sound produced by its Raptor engines or violently eroding the surrounding pad or launch mount legs with its plume.

Ultimately, once all the tower, arm, and mount work described above is completed, the only obvious thing standing between the orbital launch pad and the first Super Heavy booster testing and first orbital Starship launch will be the delivery of liquid methane fuel, which could easily begin any day now.

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

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.
