SpaceX sets stage for Starship booster’s first 33-engine static fire
SpaceX has set the stage for a record-breaking Starship booster static fire after the rocket completed a complex fueling test and launch rehearsal earlier this week.
On January 25th, a tower the size of a skyscraper activated a pair of giant mechanical arms to disassemble the largest rocket ever built. The arms carefully grabbed Starship using hard points under its flaps and lifted the 50-meter-tall second stage and spacecraft off of Super Heavy Booster 7. Nicknamed Mechazilla, the robot lowered the hundred-ton (~220,000+ lbs) vehicle hundreds of feet onto a waiting stand and eventually let go. On January 26th, SpaceX transported Ship 24 back to its Starbase, Texas factory for finishing touches.
Booster 7 remained installed on Starbase’s donut-shaped orbital launch mount, which uses clamps and umbilicals to hold Starship in place and power, fuel, and pressurize Super Heavy. In theory, the next time Booster 7 leaves that launch mount, it will do so under its own power. But first, SpaceX must ensure that that unprecedented power can be controlled (and survived).

This, unfortunately, is far from the first iteration of this story. SpaceX has been seemingly close to the milestone at many points over the last year and a half. In September 2021, for example, CEO Elon Musk reported that Super Heavy Booster 4 would attempt the first static fire on Starbase’s orbital launch mount later that month. Eleven months later, Super Heavy Booster 7 gave the OLM its inaugural static fire test – albeit with just one of its 33 engines.
In the months following that static fire, Booster 7 completed another single-engine test, a two-engine test, a seven-engine test, a fourteen-engine test, and a long-duration eleven-engine test. All of that slow and steady testing has been fairly successful and caused no major damage to the rocket or pad. But five months after it began, SpaceX has never ignited more than 14 – 42% – of Super Heavy’s 33 Raptor engines at once. That must change before SpaceX can gain enough confidence in Starship for (and convince the FAA to license) an orbital launch attempt.
During Super Heavy B7’s 14-engine static fire, the booster could have produced up to 3220 tons (7.1 million pounds) of thrust. When it ignites all 33 available engines for the first time, its maximum thrust could leap to 7590 tons (16.7 million pounds), beating the next most powerful rocket in history – the Soviet N1 – by nearly 60%. In other words, SpaceX will be attempting something unprecedented in rocketry. Success is far from guaranteed and the worst possible failure mode could almost entirely destroy Starship’s only finished orbital launch site, explaining SpaceX’s unusual caution.
On January 23rd, Ship 24 and Booster 7 completed Starship’s first full wet dress rehearsal (a fueling and launch rehearsal test) on the first try – an extremely impressive achievement for any rocket, let alone the largest in history. With that combined test out of the way, the only unprecedented test standing between Starship and its first orbital launch attempt is a 33-engine Super Heavy static fire.
To reduce risk, Ship 24 was removed from Booster 7. Back at the factory, SpaceX needs to close a few gaps left in its heat shield, and will likely also conduct careful inspections to ensure that the Starship is ready for flight. Unburdened of Ship 24, Booster 7 may finally be on the cusp of the most challenging ground test in Starship and SpaceX history. SpaceX has scheduled 12-hour road closures that could be used for that purpose as early as January 30th, 31st, and February 1st.
Those road closures could be used for Ship 25 static fire testing instead of or in addition to Booster 7. The Super Heavy is also missing an important hydraulic power unit (HPU) that was removed before the wet dress rehearsal. It’s unclear if static fire testing can be conducted without that HPU (one of two), why it was removed, or how long replacing it will take, adding more uncertainty. Nonetheless, it still appears that SpaceX is no more than a few weeks away from Starship’s first 33-engine static fire attempt.

New drone video shows Tesla’s Optimus Factory reaching a turning point
New drone footage shows Tesla’s dedicated Optimus factory steel frame nearing completion at Giga Texas.
Tesla’s dedicated Optimus factory at Gigafactory Texas is closing in on a finished steel frame, according to drone footage posted Thursday afternoon by longtime site observer Joe Tegtmeyer. In the video, Tegtmeyer said structural steel assembly is now about five column grids away from reaching the building’s north perimeter beam, putting the primary skeleton in its final stretch roughly six months after Tesla broke ground on the North Campus site in late March.

Tegtmeyer’s footage shows concrete already going in on three upper floors while crews continue laying rebar and pouring grade beam footings at ground level. That kind of parallel work, steel rising at one end of the site while concrete sets at the other, is a scheduling approach Tesla used at the original Giga Texas building and appears to be repeating here to save time before the plant’s targeted 2027 production start.
Teslarati has tracked the building’s progress since Tesla confirmed construction was officially underway in May, when the first steel structure went up on what was then bare, reclaimed land. The facility is part of a more than 5.2 million square foot expansion of Giga Texas’s North Campus that Tesla has said will eventually run nearly the length of the existing vehicle factory, over 4,000 feet, while sitting somewhat narrower. Musk has pegged the long term output target at 10 million Optimus units a year once the line is running at full capacity, a volume that would dwarf the one million unit pilot line Tesla is standing up separately at its Fremont, California factory.
Tesla Giga Texas to feature massive Optimus V4 production line
The Texas facility sits alongside another major buildout on the same campus. Terafab, the joint Tesla and SpaceX chip fabrication plant that will eventually supply the silicon running Optimus units in the field. Housing robot assembly and chip production on the same grounds is a deliberate supply chain decision, cutting down on the shipping and lead time that would otherwise sit between the two.
Tesla has not given an updated timeline beyond its previously stated goal of bringing high volume Optimus production online at the site in the summer of 2027. Fremont’s smaller pilot line began mass producing the current Gen 3 robot in January, with that plant expected to build tens of thousands of units this year primarily to generate the real world data Tesla needs to refine the robot’s software before Giga Texas ramps up. Six months of visible construction progress, tracked almost entirely through Tegtmeyer’s recurring drone flights, gives the clearest outside look yet at how seriously Tesla is treating that 2027 deadline.

Tesla and SpaceX take “Terafab” Trademark fight to Federal Court
Tesla and SpaceX sue a small Illinois firm after cease and desist letters over Terafab.
Tesla and SpaceX are asking a federal judge to rule that their planned Terafab chip factory does not infringe a small Illinois company’s trademark, a request that arrives only after months of quiet negotiation broke down this summer.
The dispute traces to May 18, when Tesla filed three U.S. trademark applications for “Terafab” and “Tesla Terafab,” covering semiconductor chips and related chip making services. TERA-print LLC, a nanotechnology company that has held a federal trademark for “Tera-Fab” since 2021, responded five days later with a cease and desist letter. According to the lawsuit, first reported by Reuters, TERA-print argued that Tesla and SpaceX’s use of “Terafab” would confuse consumers familiar with its own trademark, which covers a desktop photolithography printer sold to researchers for sensor and bioengineering work.
What stands out in the filing is the timing of TERA-print’s own paperwork. One day before sending that cease and desist letter, on May 22, TERA-print applied to expand its existing registration to cover semiconductor materials, silicon chips, nanoelectronic devices and AI design services, categories it had not previously claimed. Tesla and SpaceX call that filing opportunistic in their complaint, noting it arrived two months after Tesla’s public Terafab announcement and just days after Tesla’s own trademark applications went in.
Elon Musk launches TERAFAB: The $25B Tesla-SpaceXAI chip factory that will rewire the AI industry
By June 10, TERA-print was threatening to sue for federal trademark infringement, false designation of origin and unfair competition, the complaint states. Rather than wait to be sued, Tesla, SpaceX and SpaceXAI met with TERA-print six separate times between June and August trying to resolve the dispute directly. Those talks collapsed, and the companies filed for declaratory judgment this week in the U.S. District Court for the Western District of Texas, asking a judge to find that “Terafab” does not infringe TERA-print’s mark before TERA-print can file a claim of its own.
TERA-print isn’t backing down. The company told PCMag it discussed a settlement with Tesla as recently as September 2 and feels misled by what it called Tesla’s professed interest in settling. Its CTO, Andrey Ivankin, said TERA-print holds a Defense Department contract to fabricate semiconductors and partially owns Mattiq Inc., an AI company built on TERA-print’s products, and that the company will vigorously defend its rights.
Tesla and SpaceX argue the overlap is superficial. Terafab is planned as a $16.8 billion complex spanning roughly 100 million square feet at the Grimes County site SpaceX confirmed last month, built to produce chips for Optimus robots, Tesla’s AI computing needs and SpaceX’s orbital data center ambitions, a scale and purpose the companies say no reasonable consumer would confuse with a tabletop lab printer. TERA-print’s product line has stayed focused on lithography tools for biological and sensor research since it registered its mark in 2021.
The trademark fight is the second legal dispute tied to the Terafab project in the past week, following a separate SpaceX suit aimed at keeping company records about the facility out of public view, as KBTX reported. Whether construction proceeds under the Terafab name now depends on a federal judge in Austin.

NHTSA just escalated its Tesla Cybercab investigation in a big way
NHTSA escalated its Cybercab audit into a sworn Special Order with a September 30 deadline.
Federal regulators have moved from asking Tesla questions about its Cybercab to demanding sworn answers. The National Highway Traffic Safety Administration issued a Special Order that requires a Tesla officer to sign an affidavit attesting to the completeness of the company’s responses, with a deadline of September 30.
The order builds on Audit Query AQ26002, which NHTSA opened on September 3, the same day Tesla began commercial Cybercab service in Austin. Teslarati covered that initial inquiry when it surfaced, noting the agency wanted to understand how Tesla certified a vehicle with no permanently attached steering wheel, pedals, or mirrors as compliant with Federal Motor Vehicle Safety Standards. A Special Order is a different tool and converts a fact finding review into a legally enforceable demand, the same mechanism NHTSA used against Tesla in 2023 during its Autopilot investigation.
Several of the 21 requests target a specific gap in Cybercab’s design. One asks whether Tesla used temporarily attached human controls at any point to help certify the vehicle, and if so, which standards depended on that equipment being present. Another quotes an existing rule directly: “The service brakes shall be activated by means of a foot control.” Cybercab has no foot pedal. NHTSA wants a detailed explanation of how the vehicle satisfies that requirement, and how it complies without the kind of exemption granted to Zoox in July under Part 555, the regulatory pathway built for steering wheel free vehicles.
The order does not claim Cybercab is unsafe or that Tesla broke a rule. It requires Tesla to explain, under oath, the reasoning behind decisions the company already made when it self-certified the vehicle. That distinction matters, but so does the exposure. Motor1’s reporting, summarized here, put potential civil penalty exposure as high as $139 million if NHTSA later finds the certification was flawed, on top of whatever criminal risk comes with a false sworn statement.
Tesla has not said publicly how it plans to respond. Cybercab is still carrying passengers in Austin through the Robotaxi app while the September 30 deadline approaches, and the company has continued expanding the vehicle’s footprint even as the regulatory question remains open. The Special Order does not pause any of that and just sets a date by which Tesla has to put its certification logic on the record, with a company officer’s name attached to it.
