SpaceX Starship prototype speeding towards launch pad for first Raptor engine tests
SpaceX continues to build full-scale Starship hardware at a jaw-dropping pace, testing the limits of rocket production to complete the fifth full-scale prototype in three months and prepare the ship for its first Raptor engine ignition tests.
This time around, SpaceX CEO Elon Musk is fairly confident that the latest Starship prototype – known as serial number 3 (SN3) – has the best chance yet of becoming the first full-scale ship to pass acceptance tests and kick off a Raptor engine static fire campaign. A step further, if said static fires go according to plan, Starship SN3 could become the first full-scale vehicle of its kind to perform controlled flight tests.
Starship SN3 will thus attempt to follow in the footsteps of Starhopper and hopefully avoid an unintentional launch debut similar to the one that destroyed Starship SN1 earlier this month. A successful Starship flight test powered by three Raptor engines would be a major bode of confidence in the upgraded rocket factory SpaceX is building in South Texas. Musk recently made it clear that setting up the machine that builds the machine is currently just as important as individual Starship tests. Thankfully, given that SpaceX is already managing to build colossal rocket prototypes in a matter of weeks for what has to be pennies on the dollar, all with a team of just a few hundred people, the next Starship test campaign is likely just a week or two away.
On March 9th, Musk revealed that the Starship SN2 prototype – an incomplete tank repurposed for specific testing – had passed a proof test with flying colors. SN2’s brief test campaign managed to prove that SpaceX had already fixed the weak point believed to have destroyed Starship SN1 less than two weeks prior. Featuring a redesigned engine section and thrust structure (or “thrust puck,” per Musk), the Starship SN2 test tank survived pressure testing and even made it through engine thrust simulations with the help of an industrial-scale hydraulic jack.
While the tank passed its tests looking no worse for wear, the last-second design changes SpaceX had to make to rapidly perform thrust structure verification testing made it impossible to repurpose for any alternative use. Starship SN2 has thus been relegated to the scrapyard, a technical necessity but also a sign of both the program’s high rate of progress and low prototype cost. SpaceX’s Boca Chica factory has already more or less completed a new engine section for Starship SN3 and is probably just a day or two away from integrating it with the rest of the steel vehicle.
Less than three days after SpaceX’s brand new vehicle assembly building (VAB) had a single, small Starship section sat inside it, two additional sections of Starship SN3’s tank section departed their fabrication tents and were stacked on March 18th. Less than a day later, the third segment of the rocket’s tank section capped off the two that were stacked the day before. Once those three stacked sections are fully welded together to form a single, cohesive piece of steel, it will need to be stacked atop the aft tank dome and thrust structure to effectively complete Starship SN3’s tank section.
After all four sections are joined, technicians will need to install a few internal parts, but most remaining work mainly involves running wiring and plumbing for power, communications, propellant management, and pressurization. More likely than not, SpaceX replicate its Starship Mk1 and SN1 testing strategy and bring Starship SN3’s tank section to the launch pad for proof testing as soon as outfitting is complete. If the rocket passes proof testing, SpaceX can – for the first time – install functional Raptor engines on a full-scale Starship prototype and begin a crucial wet dress rehearsal (WDR) and static fire test campaign.
At the current rate of progress, SpaceX could easily be ready to transport Starship SN3 to the pad within the next week, give or take. Stay tuned for updates as the company works to quickly finish SN3 integration and move onto the testing phase.

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.
