SpaceX Starship launch tower stacked to full height ahead of ‘Mechazilla’ transformation
Update: After an aborted attempt on Tuesday, SpaceX has successfully installed the ninth and final section of Starship’s South Texas ‘launch tower, completing what amounts to the backbone of what CEO Elon Musk has described as a rocket-catching “Mechazilla.”
With the tower now stacked to its full ~145m (~475 ft) height, SpaceX can begin the process of outfitting it with a complex system of bus-sized actuating arms, propellant plumbing for Starship, hydraulic systems, and a network of cables and pulleys. It’s also believed that the tower structure itself will need to have each of its nine bolted steel sections welded together and all four of its steel ‘legs’ filled with concrete. However, it’s not out of the question that SpaceX will be able to activate the launch tower – albeit with a very basic degree of initial functionality – with just a few more weeks of work.
After a burst of activity and custom part deliveries, SpaceX appears to be almost ready to start turning Starship’s vast launch tower into what CEO Elon Musk has described as a “Mechazilla.”
Over the last few weeks, a number of new components have begun to quickly take shape, offering the first real glimpse of what SpaceX’s latest (hopeful) innovation might look like and how it could function. Earlier this year, Musk revealed plans to forgo landing legs entirely on earthbound Super Heavy boosters – and, potentially, Starships – by using a giant tower with arms to quite literally catch the rockets out of the air.
Those unintuitive plans have triggered wild speculation as the aerospace fans that follow SpaceX closely attempted to imagine what such a solution might look like – often engaging in a sort of vague back-and-forth with Musk himself as the CEO occasionally replied to fan-made depictions and renders.
Months after the reveal, though, parts of that tower’s rocket-manipulation mechanisms have begun to arrive on a near-constant stream of flatbed trucks and something is being assembled on a concrete pad previously used as a Starship landing zone. Two distinct structures are in work at the LZ: one a large framework assembled out of banana yellow metal tubes and the other a (for now) flatter black structure being assembled out of prefabricated components reminiscent of crane parts and trusses.
Now standing some 135m (~440 ft) tall, SpaceX’s Starship ‘launch tower’ has also been assembled from 9 different segments with what looks like six vertical rails running most of the length of three of its four rectangular legs. Since they were first spotted months ago, it’s long been assumed that those tracks will support some kind of elevator-like carriage meant to cling to the tower’s exterior. That carriage would then be outfitted with at least three (and probably five or more) large arms capable of catching, stabilizing, and fueling Starship.
Over the last week or so, SpaceX has also been hard at work completing the ninth and final section – believed to be the roof – of the launch tower. In the last few days, that four-legged tower section has been outfitted with an interesting appendage that itself was then fitted with several massive sheaves (i.e. pulleys). That hardware will likely become part of a high-power pulley system that will pull the arm carriage up and down the tower, allowing it to grab, lift, and catch Starships and Super Heavy boosters.
By all appearances, SpaceX is preparing to install the launch tower’s last prefabricated section, likely raising the tower to its final ~145m (~475 ft) height. It’s possible that a crane of some kind will be permanently installed on top of the tower but it currently looks like SpaceX intends to rely exclusively on the tower’s arms to install, stack, stabilize, fuel, and (maybe) catch Starship and Super Heavy.

Elon Musk handed Grok something no other AI company can get their hands on
Elon Musk says SpaceX will feed engineering data into Grok’s next model, avoiding restricted material.
Elon Musk said Tuesday that SpaceX will feed its internal engineering data into the next major training run for Grok, the AI model now folded into SpaceX following February’s merger. In a post on X, Musk wrote that SpaceX’s “massive corpus of world-class engineering data,” excluding anything restricted under U.S. arms export law, will be added during supplemental training of what he called the “2T run,” a reference to a roughly two trillion parameter model that would nearly double the parameters behind the latest Grok 4.5 that’s rolling out.
SpaceX’s massive corpus of world-class engineering data (excluding material blocked by ITAR) will be added during supplemental training of the 2T run.
This will dramatically improve Grok’s engineering capabilities. https://t.co/BbQEViFByn

The excluded material that Musk is referring to would fall under the International Traffic in Arms Regulations (ITAR), which restricts export of technical data tied to defense and space hardware. That likely rules out propulsion specifics for Merlin and Raptor engines along with guidance and control details for SpaceX’s launch vehicles, but leaves manufacturing knowledge, materials science, and Starlink hardware design on the table.
The announcement extends a pattern that has been building since SpaceX’s Nasdaq debut in June, when the company went public with Grok and xAI’s Colossus supercomputer folded into the pitch to investors.
Days after that listing, SpaceX closed its $60 billion all stock acquisition of coding startup Cursor, giving xAI both enterprise software distribution and a stream of real world developer data to train on. Grok 4.5 launched July 8 running partly on that Cursor training data, with Musk describing it as roughly comparable to Anthropic’s Opus 4.7 but faster and cheaper to run.
Feeding SpaceX’s own engineering data into the next AI model follows the same logic Musk has applied across xAI’s sister companies. Tesla supplies real world driving data and manufacturing expertise, X supplies conversational data, and now SpaceX supplies aerospace engineering data built up since 2002.
Musk did not give a release date for the upcoming AI model, referred to elsewhere as Grok 4.6. He has said the two trillion parameter run is in its final training phase and expected to wrap this week.
Tesla has extended its Bay Area ride-hailing service to include pickups and drop-offs at San Francisco International Airport (SFO). The update, shared via the company’s official channels on July 21, allows users in the region to request rides directly to and from one of California’s busiest airports.
The expansion builds on Tesla’s secured limousine permit for SFO operations. Public records show the permit became effective March 20, 2026, and remains active through January 31, 2027. Tesla vehicles operating the service now display authorized limousine permits issued by the City and County of San Francisco.

Tesla’s ride-hailing program in California relies on Model Y vehicles equipped with Full Self-Driving (Supervised) technology. Human safety drivers remain present in compliance with state regulations, distinguishing the service from fully driverless operations.
The Bay Area geofence covers a broad area spanning north of San Francisco to south of San Jose, offering extensive connectivity across the region.
UPDATE: Elon Musk reveals why Tesla didn’t say ‘Robotaxi’ upon California launch
This SFO addition follows earlier progress at other Bay Area airports. Tesla previously expanded service to San Jose Mineta International Airport (SJC) in late 2025. The company had engaged with SFO, SJC, and Oakland International Airport officials as early as September 2025 to secure necessary approvals for passenger transport.
The service provides a new option for travelers seeking electric, app-based transportation integrated with Tesla’s ecosystem. Rides are booked through Tesla’s dedicated ride-hailing application, which handles matching, routing, and payments. Pricing follows standard ride-hailing models, with potential adjustments based on distance, time, and demand.
Tesla’s California ride-hailing program launched in July 2025 with an initial invite-only rollout in the Bay Area. It started alongside operations in Austin, Texas, marking the company’s second major U.S. market.
The Bay Area remains a primary focus in California, with service centered on high-demand corridors connecting residential, commercial, and now major transportation hubs. This latest airport integration represents a practical step in Tesla’s broader mobility ambitions within the state.
