SpaceX aborts several Starship static fire attempts, rolls test tank to the pad
Accidentally producing the polar opposite of Starship serial number 9 (SN9) completing a trio of Raptor ignition tests in four hours last week, SpaceX has now suffered three back-to-back static fire aborts on January 20th.
On January 13th, Starship SN9 somewhat successfully ignited its Raptor engines three separate times with zero hands-on human intervention or inspection. While an impressive feat, SpaceX CEO Elon Musk soon revealed that two of the rocket’s three engines were damaged during the test campaign. NASASpaceflight.com later reported that the company had detected an issue with one Raptor after the first three-engine static fire, ultimately firewalling it and performing the next two static fires with only two engines.
SpaceX initially allotted five days to replace the two damaged Raptors (SN44 & SN46), scheduling road closures (a telltale sign of test plans) on January 18th, 19th, and 20th. Windows on the 18th and 19th went by with zero attempts. Finally, on the 20th, SpaceX kicked off Starship SN9’s first real test attempt since the engine swap around 2pm but it was aborted by 3pm.
After an extremely brisk recycle, Starship likely made it less than a minute away from ignition but the second attempt was ultimately aborted around 3:40 pm.
Two hours later, after SpaceX extended the end of its road closure from 5pm to 8pm, Starship SN9’s third Raptor static fire attempt was also aborted – once again just a minute or less away from ignition.
SpaceX held Starship SN9 for another hour or so after the third abort but ultimately began final detanking and depressurization around 6:50 pm, marking the end of the day’s attempts.
It’s impossible to say what caused Wednesday’s back-to-back-to-back aborts or if the three instances were connected. While potentially frustrating to watch from the sidelines, it’s crucial to remember that the public is getting a truly unprecedented continuous view of SpaceX’s process of developing and refining a world-class launch vehicle. Additionally, every abort Starship suffers should theoretically produce volumes of valuable data that both Starship and Raptor teams can use to better understand how to design, build, test, and operate the cutting-edge vehicle and its engines.
More likely than not, SpaceX is leaning towards caution (and thus cautious hardware and software limits) while attempting to prepare Starship SN9 for its true data-gathering purpose – an SN8-style high-altitude launch and landing attempt.
SpaceX is currently scheduled to try again with another series of Starship SN9 static fire attempts between 8am and 5pm CST (UTC-6) on Thursday, January 21st.
Meanwhile, prior to SN9’s multiple Wednesday aborts, SpaceX rolled the latest in a series of Starship ‘test tanks’ from the factory to the launch pad. A team rapidly strapped the tank to the concrete pad and connected it to ground support equipment in preparation for a series of tests that will likely end with SpaceX intentionally pressurizing the tank until its bursts. If successful, it will open the door for future Starships to save weight by cutting steel skin thickness from 4mm to 3mm.
Stay tuned for updates on both active test campaigns.

The Boring Company’s Prufrock-2 emerges after completing new Vegas Loop tunnel
The new tunnel measures 2.28 miles, making it the company’s longest single Vegas Loop tunnel to date.
The Boring Company announced that its Prufrock-2 tunnel boring machine (TBM) has completed another Vegas Loop tunnel in Las Vegas. The company shared the update in a post on social media platform X.
According to The Boring Company’s post, the new tunnel measures 2.28 miles, making it the company’s longest single Vegas Loop tunnel to date.
The new tunnel marks the fourth tunnel constructed near Westgate Las Vegas as the Vegas Loop network continues expanding across the city.
The Boring Company also noted that the new tunnel surpassed its previous internal record of 2.26 miles for a single Vegas Loop segment.
Construction of the tunnel involved moving roughly 68,000 cubic yards of dirt. The excavation process also used about 4.8 miles of continuous conveyor belt, powered by six motors totaling 825 horsepower.
The Boring Company’s Prufrock-series all-electric tunnel boring machines are designed to support the rapid expansion of company’s underground transportation projects, including the growing Vegas Loop network. Prufrock machines are designed for reusability, thanks in no small part to their capability to be deployed and retrieved easily through their “porposing” feature.
The Vegas Loop, specifically the Las Vegas Convention Center (LVCC) Loop segment, has already been used during major events. Most recently, the LVCC Loop supported the 2026 CONEXPO-CON/AGG construction trade show, which was held from March 3-7, 2026.
As per The Boring Company, the LVCC Loop transported roughly 82,000 passengers across the convention center campus during the event’s duration.
CONEXPO-CON/AGG is one of the largest construction trade shows in North America, drawing more than 140,000 construction professionals from 128 countries this year.
The LVCC Loop forms the initial segment of the broader Vegas Loop network, which remains under active development as The Boring Company continues building new tunnels throughout the city.

Tesla gathers Cybercab fleet in Gigafactory Texas
Images and video of the Cybercab fleet were shared by longtime Giga Texas observer Joe Tegtmeyer in posts on social media platform X.
Tesla appears to be assembling a growing number of Cybercabs at Gigafactory Texas as preparations continue for the vehicle’s mass production. Recent footage shared online has shown over 30 Cybercabs being transported by trucks or staged near testing areas at the facility.
The images and video were shared by longtime Giga Texas observer and drone operator Joe Tegtmeyer in posts on social media platform X.
Interestingly enough, Tegtmeyer noted that many of the Cybercabs being loaded onto transport trucks were still equipped with steering wheels. This suggests that the vehicles are likely testing units rather than the final driverless configuration expected for the company’s Robotaxi service.
The vehicles could potentially be headed to testing sites across the United States as Tesla prepares to expand its Robotaxi fleet.
Additional footage captured at Gigafactory Texas also showed the Cybercab’s side and rear camera washer system operating as vehicles were being loaded onto transport trucks.
The growing number of Cybercabs at Giga Texas comes amidst the company’s announcement that the first production Cybercab has been produced at the facility. Full Cybercab production is expected to begin in April.
The vehicle is expected to play a central role in Tesla’s Robotaxi ambitions as the company looks to expand autonomous ride-hailing operations beyond its early deployments using Model Y vehicles.
Tesla has also linked Cybercab production to its proposed Unboxed manufacturing process, which assembles large vehicle modules separately before integrating them. The approach is intended to reduce production costs and accelerate output.
Musk has also noted that the Cybercab’s ramp will likely begin slowly due to the number of new components and manufacturing steps involved. However, he stated that once the process matures, Cybercab production could scale quickly.

Elon Musk’s xAI, creator of Grok and Grokipedia, celebrates its third birthday
xAI Memphis highlighted several of its milestones over the years in its celebratory post.
Elon Musk’s artificial intelligence startup xAI has marked its third anniversary. The update was shared in a post from the xAI Memphis account on social media platform X.
xAI Memphis highlighted several of its milestones over the years in its celebratory post.
As per xAI, it has built three massive data centers in the city, launched a coherent cluster of 330,000 GBs, created over 3,000 jobs, and paid over $30 million in taxes to local communities.
xAI’s Memphis operation has become a key part of the company’s infrastructure as the company works to train and deploy its Grok artificial intelligence models. Elon Musk has been quite optimistic about Grok’s potential, noting in the past that the large language model might have a shot at achieving artificial general intelligence (AGI).
xAI’s Memphis’ crown jewel is its Colossus supercomputer cluster. The project was announced in 2024 and has since become the home of one of the world’s largest AI compute facilities. The first phase of Colossus reached its initial 100,000 GPU operational milestone in just 122 days, or just about four months.
Industry figures such as Nvidia CEO Jensen Huang have praised the facility, noting that projects of similar scale typically take two to four years to complete.
xAI has cited Memphis’ central location, skilled workforce, and industrial infrastructure as key reasons for selecting the city as the home of its AI training operations. The company has also emphasized plans to expand the site further as it scales compute capacity for Grok and future AI models.
