SpaceX reinstalling 29 Raptor engines on first orbital-class Starship booster
For the second time this month, SpaceX has begun installing 29 Raptor engines on Starship’s first orbital-class Super Heavy booster, potentially paving the way for several crucial milestones.
On August 1st, around the same time as SpaceX finished installing car-sized grid fins on a Super Heavy for the first time, the company began the process of installing multiple Raptor engines on the booster (#4) that might one day support Starship’s first orbital launch attempt. Not long after it began, it became clear that SpaceX was installing a full 29 Raptor engines on Booster 4 (B4) at a breakneck pace, and less than 24 hours later, all had been attached to Super Heavy’s thrust structure.
Barely a day later, Super Heavy Booster 4 was rolled to the orbital launch pad and installed on a massive ‘launch table’ that was itself installed just a few days prior after months of assembly. Four days after engine installation, Starship S20 and Booster 4 were briefly mated together, forming a full Starship stack – the tallest and most powerful rocket ever built – for about an hour. However, while it did serve as a useful learning experience and pathfinder operation, both stages were demated and returned to the factory soon after.
Since Booster 4’s later August 11th build site return, SpaceX teams have been hard at work fitting the massive 69m (225 ft) tall rocket booster with thousands of feet (if not miles) of secondary plumbing and power and avionics cables. That process effectively began with removing the Super Heavy’s 29 Raptor engines, which finished just a few days after its return to the high bay.
Now, just 12 days after Super Heavy Booster 4 arrived back at the high bay and 11 days after workers briskly removed its Raptors, SpaceX has begun the process of reinstalling those engines – albeit with several new entrants this time around. When SpaceX first fitted B4 with Raptors, it became clear that five or more of had never been tested, making the removal of some of the Super Heavy’s 29 engines more or less inevitable. Indeed, as expected, several new Raptors (engines that weren’t clearly installed the first time around) have joined around two dozen engines that were installed earlier this month.
Given that Booster 4 has already completed a range of fit checks, the implication is that SpaceX is now installing the 29 Raptor engines that will support the first static fire test campaign of a flightworthy Super Heavy. Of course, that testing (likely involving several different static fires of an increasing number of Raptors) could unearth issues or even damage some of those 29 Raptors, so it isn’t quite accurate to say that Booster 4 is being fitted with the engines that will help it carry Starship to orbit. Depending on the outcome of those tests, though, most could easily find themselves lifting off on Super Heavy B4 later this year.
For now, though, Super Heavy Booster 4’s next milestone will be its second trip from the build site to the launch pad. That could occur at any point in the next week or two and could find Booster 4 installed beside Ship 20 on the second of two suborbital test stands, though the Super Heavy may instead return to the orbital launch site.

Tesla ships out update that brings massive change to two big features
“This change only updates the name of certain features and text in your vehicle,” the company wrote in Release Notes for the update, “and does not change the way your features behave.”
Tesla has shipped out an update for its vehicles that was caused specifically by a California lawsuit that threatened the company’s ability to sell cars because of how it named its driver assistance suite.
Tesla shipped out Software Update 2026.2.9 starting last week; we received it already, and it only brings a few minor changes, mostly related to how things are referenced.
“This change only updates the name of certain features and text in your vehicle,” the company wrote in Release Notes for the update, “and does not change the way your features behave.”
The following changes came to Tesla vehicles in the update:
- Navigate on Autopilot has now been renamed to Navigate on Autosteer
- FSD Computer has been renamed to AI Computer
Tesla faced a 30-day sales suspension in California after the state’s Department of Motor Vehicles stated the company had to come into compliance regarding the marketing of its automated driving features.
The agency confirmed on February 18 that it had taken a “corrective action” to resolve the issue. That corrective action was renaming certain parts of its ADAS.
Tesla discontinued its standalone Autopilot offering in January and ramped up the marketing of Full Self-Driving Supervised. Tesla had said on X that the issue with naming “was a ‘consumer protection’ order about the use of the term ‘Autopilot’ in a case where not one single customer came forward to say there’s a problem.”
This was a “consumer protection” order about the use of the term “Autopilot” in a case where not one single customer came forward to say there’s a problem.
Sales in California will continue uninterrupted.

It is now compliant with the wishes of the California DMV, and we’re all dealing with it now.
This was the first primary dispute over the terminology of Full Self-Driving, but it has undergone some scrutiny at the federal level, as some government officials have claimed the suite has “deceptive” names. Previous Transportation Secretary Pete Buttigieg was one of those federal-level employees who had an issue with the names “Autopilot” and “Full Self-Driving.”
Tesla sued the California DMV over the ruling last week.

Tesla workers push back against Giga Berlin unionization
“IG Metall did not succeed in Giga Berlin‘s works council election earlier today. The union share was reduced from nearly 40% in 2024 to 31% in 2026! This is a clear message by the Giga Berlin team towards an independent co-determination! The list called Giga United, led by the current chairwoman, Michaela Schmitz, received the most votes with more than 40%! Good news for Giga Berlin!”
Tesla workers pushed back against unionization efforts at Gigafactory Berlin, and over the past few years, there has been a dramatic decrease in interest to unionize at the German plant.
Gigafactory Berlin Plant Manager André Thierig announced on Wednesday that IG Metall, the European union group, saw its share reduce from 40 to 31 percent in 2026 as employees eligible to vote on the issue. Instead, the Giga Berlin team, known as Giga United, received the most votes with more than 40 percent.

Thierig gave specific details in a post on X:
“IG Metall did not succeed in Giga Berlin‘s works council election earlier today. The union share was reduced from nearly 40% in 2024 to 31% in 2026! This is a clear message by the Giga Berlin team towards an independent co-determination! The list called Giga United, led by the current chairwoman, Michaela Schmitz, received the most votes with more than 40%! Good news for Giga Berlin!”
There were over 10,700 total employees who were eligible to vote, with 87 percent of them turning out to cast what they wanted. There were three key outcomes: Giga United, IG Metall, and other notable groups, with the most popular being the Polish Initiative.
The 37-seat council remains dominated by non-unionized representatives, preserving Giga Berlin as Germany’s only major auto plant without a collective bargaining agreement.
Thierig and Tesla framed the outcome as employee support for an “independent, flexible, and unbureaucratic” future, enabling acceleration on projects like potential expansions or new models. IG Metall expressed disappointment, accusing management of intimidation tactics and an “unfair” campaign.
The first election of this nature happened back in 2022. In 2024, IG Metall emerged as the largest single faction with 39.4 percent, but non-union lists coalesced for a majority.
But this year was different. There was some extra tension at Giga Berlin this year, as just two weeks ago, an IG Metall rep was accused by Tesla of secretly recording a council meeting. The group countersued for defamation.

This result from the 2026 vote reinforced Tesla’s model of direct employee-management alignment over traditional German union structures, amid ongoing debates about working conditions. IG Metall views it as a setback but continues advocacy. Tesla sees it as validation of its approach in a competitive EV market.
This outcome may influence future labor dynamics at Giga Berlin, including any revival of expansion plans or product lines, which Musk has talked about recently.

SpaceX President Gwynne Shotwell details xAI power pledge at White House event
The commitment was announced during an event with United States President Donald Trump.
SpaceX President Gwynne Shotwell stated that xAI will develop 1.2 gigawatts of power at its Memphis-area AI supercomputer site as part of the White House’s new “Ratepayer Protection Pledge.”
The commitment was announced during an event with United States President Donald Trump.
During the White House event, Shotwell stated that xAI’s AI data center near Memphis would include a major energy installation designed to support the facility’s power needs.
“As you know, xAI builds huge supercomputers and data centers and we build them fast. Currently, we’re building one on the Tennessee-Mississippi state line. As part of today’s commitment, we will take extensive additional steps to continue to reduce the costs of electricity for our neighbors…
“xAI will therefore commit to develop 1.2 GW of power as our supercomputer’s primary power source. That will be for every additional data center as well. We will expand what is already the largest global Megapack power installation in the world,” Shotwell said.
She added that the system would provide significant backup power capacity.
“The installation will provide enough backup power to power the city of Memphis, and more than sufficient energy to power the town of Southaven, Mississippi where the data center resides. We will build new substations and invest in electrical infrastructure to provide stability to the area’s grid.”
Shotwell also noted that xAI will be supporting the area’s water supply as well.
“We haven’t talked about it yet, but this is actually quite important. We will build state-of-the-art water recycling plants that will protect approximately 4.7 billion gallons of water from the Memphis aquifer each year. And we will employ thousands of American workers from around the city of Memphis on both sides of the TN-MS border,” she noted.
The Ratepayer Protection Pledge was introduced as part of the federal government’s effort to address concerns about rising electricity costs tied to large AI data centers, as noted in an Insider report. Under the agreement, companies developing major AI infrastructure projects committed to covering their own power generation needs and avoiding additional costs for local ratepayers.
