SpaceX Starship rocket’s flight debut set for Monday
For the first time ever, a full-scale SpaceX Starship prototype could be less than a day away from an inaugural flight test in Boca Chica, Texas.
Expected to target the same 150m (~500 ft) maximum altitude as Starhopper’s final flight, the hop will see the full-scale tank section of Starship SN5 attempt to follow in the footsteps of its odd predecessor. Starhopper was essentially a back-of-the-envelope proof of concept, demonstrating that a large rocket could technically be built out of common steel with facilities so spartan and basic that it defied belief.
While much shorter than a full-scale Starship, against all odds, Starhopper completed multiple wet dress rehearsals with methane and oxygen propellant, several static fires with Raptor engines, and two untethered flight tests (hops). The first of those tests saw Starhopper reach ~20m (~65 ft) on July 25th, 2019, while the stout Starship prototype went on to reach 150m (~500 ft) on its second and final flight barely a month later (August 27th). Now, a few weeks shy of one year later, Starship SN5 seeks to carry the torch forward with its own 150m hop.
This is not the first time that Starship SN5’s hop debut has seemed close at hand, however. For a number of reasons, most of which likely center around extensive damage done to SpaceX’s Boca Chica launch facilities when Starship SN4 exploded, SN5’s path to first flight has been plagued by delays. For a prototype of any kind, that’s not fundamentally unusual, but it’s been exceptional as far as SpaceX’s Starship development program goes. Prior to those delays, public road closures showed that SpaceX planned to launch Starship SN5 for the first time as early as mid-July.
For several weeks, SpaceX gradually worked the kinks of the repaired pad’s ground support equipment (GSE) and Starship SN5 itself with four aborted attempts, finally reaching a point where the rocket was able to static fire its Raptor engine for the first time on July 31st. After many, many delays and minor issues, the static fire test went extremely smoothly – possibly the smoothest-looking Starship test SpaceX has thus far completed.
The private results from that test must have also looked great because SpaceX initially wanted to turn Starship SN5 around for its hop debut on Sunday, August 2nd – barely two days later. Yesterday’s window came and went, though, and SpaceX ultimately pushed its hop test plans back by 24 hours and added a new backup window on August 4th.
The window for Starship SN5’s 150m hop debut now stretches from 8am to 8pm CDT (13:00-01:00 UTC) on Monday, August 3rd. It’s currently unknown if SpaceX will offer its own live coverage of the test flight but several unofficial streams will likely be available from NASASpaceflight.com, LabPadre, SPadre, and more.

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.
