SpaceX execs bullish on BFR as Mars rocket test facilities expand in Texas [photos]
Aerial observations of SpaceX’s McGregor, Texas testing facilities on April 17 revealed an unusually frenetic level of construction and expansion centered around Raptor – the rocket engine intended to power BFR and SpaceX to Mars – and a new test-stand, the purpose of which is currently unknown.
With a minimum of 1200 seconds of hot-fires under its belt, SpaceX’s Raptor propulsion program is likely rapidly approaching the end of what is best described as the experimental phase of testing. While this has not been communicated by SpaceX, it is a logical conclusion following several recent developments. Namely the true beginning of BFR test article fabrication and an impressively bullish level of commitment and confidence in the fully reusable launch system demonstrated in the last few months alone by CEO Elon Musk and President/COO Gwynne Shotwell. While Musk is infamous both within and beyond his companies for painfully impractical development timelines, he demonstrated some level of growing consciousness of that fallibility at 2018’s SXSW, stating that he was working on recalibrating his expectations. Without taking a breath, he reiterated his anticipation for short hop tests of the first full-scale spaceship prototype in the first half of 2019.

While anyone familiar with Musk’s timeline antics may roll their eyes and laugh, far more shocking was Shotwell’s sudden pivot towards a new sense of optimism for the BFR program. At Satellite Conference 2018, the typically reserved and pragmatic executive confirmed beyond any doubt that she had become aggressively bullish on the Mars rocket, stating that she believed the spaceship would be ready for suborbital testing in 2019, while the booster-spaceship system could potentially reach orbit by 2020. Musk and Shotwell’s suggestion that BFR’s first suborbital testing – akin to an extreme version of SpaceX’s Grasshopper and F9R programs – is expected to begin in 2019 meshes well with a recent explosion of activity at Port of San Pedro in Los Angeles, CA, thanks to a combination of land acquisition, successful bureaucracy-wrangling, and the first hints of construction and BFR production. It’s highly unlikely that SpaceX would have chosen to temporarily move BFR prototyping into a giant tent on abandoned dock space rather than waiting for port and city approvals for their permanent port factory if they were not keen on moving full speed ahead with the fully reusable launch vehicle’s development.

SpaceX’s Director of Real-Estate Bruce McHugh was less confident when he spoke before Port of San Pedro’s board of commissioners on April 19, although all in attendance expressed a huge amount of excitement at the increasingly likely prospects of a huge SpaceX rocket factory materializing in their neighborhood. Local contractors, economic development representatives, and many other community members were eager for the approval and permitting process to finish up, after which SpaceX is characteristically likely to begin demolition and construction in earnest at Berth 240, the prospective site for the company’s first dedicated BFR factory.
Early phases of in-house BFR structures prototyping is taking shape behind the flaps of a custom-ordered temporary tent, something like 60m long, 30m wide, and ~15m tall at the highest point – half an acre of eccentric but functional space for Mars rocket R&D, in other words. The primary benefit of these facilities’ dock-side locations is the minimization of the transportation hell that SpaceX would have had to suffer through to transport 9m-diameter rocket hardware through downtown Los Angeles – feats that would cost as much as $2.5 million one way each time components had to be moved from the Hawthorne factory to the Port of LA, where it would be finally shipped to Texas or Florida.

Speaking at a private talk given to MIT campus members in October 2017, attendees reported that Shotwell stated that although “[BFR’s] composite tanks [would] be a challenge [for SpaceX],” the company was already working on maturing the technologies required, and also noted that SpaceX was “building a larger [version of] Raptor right now.” Half a year later, outsiders have heard nothing of any additional carbon composite propellant tank testing at the new 9m diameter, but the existence of custom-ordered (i.e. very expensive and specialized) composite fabrication tooling of the same diameter as BFR effectively guarantees that SpaceX has settled upon and is confident in its approach to manufacturing the massive composite tankage and structures. Along with a similar line of thought, expensive tooling with a fixed diameter also indicates – albeit with less certainty – that the vehicle’s Raptor propulsion system is not expected to change significantly as BFR marches closer to suborbital and orbital testing. Raptor, in other words, is probably considerably more mature than SpaceX’s composite tankage expertise, itself fairly advanced given the mandrel and additional fabrication tooling already present at Port of San Pedro.
And yet, Shotwell’s most telling display of confidence occurred just a handful of days ago at the TED2018 conference. In a lengthy and fairly well-orchestrated interview with the session’s host Chris Anderson, Shotwell repeatedly and happily made comments indicating that she has become extremely bullish on BFR and BFS in the last several months. In her opinion, BFR (and point-to-point Earth transport) will be deployed “within a decade, for sure.” Prices would nominally be “between business and economy,” or a few thousand dollars per person. Speaking on the trip from Earth to Mars, she estimated a three-month journey with BFR Block 1, “but [SpaceX is] gonna try to do it faster.” She further confirmed that SpaceX intends to build much larger BFRs, meshing with Elon’s suggestions that 2016’s ITS concept is now perceived internally as a sort of BFR Block 2. Perhaps most importantly, she qualified her timeline estimates as “Gwynne-time” when Anderson jokingly deadpanned about the infamous Elon-time. Overall, Shotwell came across as more bullish than she has ever been before on BFR’s development and future prospects, including both point-to-point transport on Earth and crewed missions to the surface of Mars – both of which she expected to begin “within a decade, for sure.” Smirking, she quipped that she was “sure Elon would want us to go faster.”

Not one to end on a quiet note, the typically pragmatic executive finished by describing how she believed that spreading human presence throughout the Sol System was only “the first step [towards] moving to other solar systems and potentially other galaxies; I think this is the only time I ever out-vision Elon.” Interstellar travel and faster-than-light propulsion aspirations aside, Shotwell’s comments mark a fairly incredible shift in attitude toward SpaceX’s far loftier ambitions. Musk seems to be working to recalibrate his timelines to be less naive at the same time as Shotwell’s confidence is steadily growing – the two executives, in other words, appear to be rapidly converging upon a middle ground of pragmatic optimism (that or Musk-time is contagious!).

As shown above, the level of construction activity at SpaceX’s Texas testing facilities is fairly impressive and could perhaps be seen as evidence that both Musk and Shotwell are speaking from a place of something approaching pragmatism. While the purpose of the new stand (center) is not yet clear, several aspects indicate that it is unlikely to be more mundane. First, the massive water tower (one that did not exist just a month or two ago, might I add) dwarfs anything found at individual engine or upper stage test stands at the SpaceX facility. It’s possible that the existence of the flame trench alone necessitates the inclusion of such a large water suppression system for damage prevention, but the presence of the blue steel skeleton of a new flame bucket (operational iterations shown on the right) suggests otherwise. For example, the Merlin stands have no such water suppression system: they do use water suppression to avoid damaging the ground systems or the engines themselves, but that water is stored in a large ground-level tank. A tower, however, indicates that SpaceX wants much higher water pressures and flow rates to be available at the new stand, a requirement for significantly more powerful tests akin to SpaceX’s full-up Falcon 9 (and Heavy) test stand – the water towers at the S1 stand and this new stand appear to be identical in size.
In other words, it’s more probable than not that this new stand is being built to support either booster static fires or much larger tests of BFR hardware (perhaps multiple Raptors at once, akin to SpaceX’s very early tests of Falcon 9’s nine Merlins). It could, of course, be used for many different tasks, but only time will tell. Given the sheer level of physical progress made in the BFR program and the swelling confidence of Musk and Shotwell, I certainly know where I’d hedge my bets.

Tesla has finished construction at its biggest Supercharger ever in Lost Hills, California, and all 168 stalls are officially open as of today.
After several years of development, the company has officially announced that the Lost Hills Supercharger, known as Project Oasis, is officially open with 168 stalls active and available to drivers.
Tesla announced the completion of the Lost Hills Supercharger on Tuesday, showing off the site, which is powered by 10 Megapack batteries for storage and is completely independent of the grid, as it has 11 MW of solar panels bringing energy to the massive Battery Energy Storage System (BESS).

This is the largest Supercharger in the world and opens just in time for the Thanksgiving holiday, which is the most-traveled weekend of the year in the United States.
Spanning across 30 acres, it was partially opened back in July 2025 as Tesla opened just 84 of the 168 stalls at the site. However, Tesla finished certifying the site recently, which enabled the Supercharger to open up completely.
The site generates roughly 20 GWh of energy annually, which is enough to power roughly 1,700 homes. The launch of this site specifically is massive for the company as it plans to launch more Superchargers in more rural areas, making charging more available for cross-country rides that require stops in more remote regions of the United States.
This is perhaps the only weak point of Tesla’s massive charging infrastructure.
It has some features that are also extremely welcome for some owners, including things like pull-through stalls for those who tow, an idea that was extremely popular following the launch of the Cybertruck.
Tesla has over 70,000 active Superchargers across the world. The company has also made efforts to create unique experiences at some of the stops, most notably with its Tesla Diner, located on Santa Monica Boulevard in Los Angeles.
That Supercharger has two massive drive-in movie theaters and will soon transition to a full-service restaurant following the departure of its executive chef, Eric Greenspan.

Elon Musk proposes Grok 5 vs world’s best League of Legends team match
Musk’s proposal has received positive reception from professional players and Riot Games alike.
Elon Musk has proposed a high-profile gaming challenge for xAI’s upcoming Grok 5. As per Musk, it would be interesting to see if the large language model could beat the world’ best human League of Legends team with specific constraints.
Musk’s proposal has received positive reception from professional players and Riot Games alike, suggesting that the exciting exhibition match might indeed happen.
Musk outlines restrictions for Grok
In his post on X, Musk detailed constraints to keep the match competitive, including limiting Grok to human-level reaction times, human-speed clicking, and viewing the game only through a camera feed with standard 20/20 vision. The idea quickly circulated across the esports community, drawing commentary from former pros and AI researchers, as noted in a Dexerto report.
Former League pro Eugene “Pobelter” Park expressed enthusiasm, offering to help Musk’s team and noting the unique comparison to past AI-versus-human breakthroughs, such as OpenAI’s Dota 2 bots. AI researcher Oriol Vinyals, who previously reached Grandmaster rank in StarCraft, suggested testing Grok in RTS gameplay as well.
Musk welcomed the idea, even responding positively to Vinyals’ comment that it would be nice to see Optimus operate the mouse and keyboard.
Pros debate Grok’s chances, T1 and Riot show interest
Reactions weren’t universally optimistic. Former professional mid-laner Joedat “Voyboy” Esfahani argued that even with Grok’s rapid learning capabilities, League of Legends requires deep synergy, game-state interpretation, and team coordination that may be difficult for AI to master at top competitive levels. Yiliang “Doublelift” Peng was similarly skeptical, publicly stating he doubted Grok could beat T1, or even himself, and jokingly promised to shave his head if Grok managed to win.
T1, however, embraced the proposal, responding with a GIF of Faker and the message “We are ready,” signaling their willingness to participate. Riot Games itself also reacted, with co-founder Marc Merrill replying to Musk with “let’s discuss.” Needless to say, it appears that Riot Games in onboard with the idea.
Though no match has been confirmed, interest from players, teams, and Riot suggests the concept could materialize into a landmark AI-versus-human matchup, potentially becoming one of the most viewed League of Legends events in history. The fact that Grok 5 will be constrained to human limits would definitely add an interesting dimension to the matchup, as it could truly demonstrate how human-like the large language model could be like in real-time scenarios.
Tesla has passed a key milestone, and it was one that CEO Elon Musk initially mentioned more than nine years ago when he published Master Plan, Part Deux.
As per Tesla China in a post on its official Weibo account, the company’s Autopilot system has accumulated over 10 billion kilometers of real-world driving experience.
Tesla China’s subtle, but huge announcement
In its Weibo post, Tesla China announced that the company’s Autopilot system has accumulated 10 billion kilometers of driving experience. “In this respect, Tesla vehicles equipped with Autopilot technology can be considered to have the world’s most experienced and seasoned driver.”
Tesla AI’s handle on Weibo also highlighted a key advantage of the company’s self-driving system. “It will never drive under the influence of alcohol, be distracted, or be fatigued,” the team wrote. “We believe that advancements in Autopilot technology will save more lives.”
Tesla China did not clarify exactly what it meant by “Autopilot” in its Weibo post, though the company’s intense focus on FSD over the past years suggests that the term includes miles that were driven by FSD (Beta) and Full Self-Driving (Supervised). Either way, 10 billion cumulative miles of real-world data is something that few, if any, competitors could compete with.

Elon Musk’s 10-billion-km estimate, way back in 2016
When Elon Musk published Master Plan Part Deux, he outlined his vision for the company’s autonomous driving system. At the time, Autopilot was still very new, though Musk was already envisioning how the system could get regulatory approval worldwide. He estimated that worldwide regulatory approval will probably require around 10 billion miles of real-world driving data, which was an impossible-sounding amount at the time.
“Even once the software is highly refined and far better than the average human driver, there will still be a significant time gap, varying widely by jurisdiction, before true self-driving is approved by regulators. We expect that worldwide regulatory approval will require something on the order of 6 billion miles (10 billion km). Current fleet learning is happening at just over 3 million miles (5 million km) per day,” Musk wrote.
It’s quite interesting but Tesla is indeed getting regulatory approval for FSD (Supervised) at a steady pace today, at a time when 10 billion miles of data has been achieved. The system has been active in the United States and has since been rolled out to other countries such as Australia, New Zealand, China, and, more recently, South Korea. Expectations are high that Tesla could secure FSD approval in Europe sometime next year as well.

Elon Musk’s Boring Company reveals Prufrock TBM’s most disruptive feature
As it turns out, the tunneling startup, similar to other Elon Musk-backed ventures, is also dead serious about pursuing reusability.
The Boring Company has quietly revealed one of its tunnel boring machines’ (TBMs) most underrated feature. As it turns out, the tunneling startup, similar to other Elon Musk-backed ventures, is also dead serious about pursuing reusability.
Prufrock 5 leaves the factory
The Boring Company is arguably the quietest venture currently backed by Elon Musk, inspiring far fewer headlines than his other, more high-profile companies such as Tesla, SpaceX, and xAI. Still, the Boring Company’s mission is ambitious, as it is a company designed to solve the problem of congestion in cities.
To accomplish this, the Boring Company would need to develop tunnel boring machines that could dig incredibly quickly. To this end, the startup has designed Prufrock, an all-electric TBM that’s designed to eventually be fast enough as an everyday garden snail. Among TBMs, such a speed would be revolutionary.
The startup has taken a step towards this recently, when The Boring Company posted a photo of Prufrock-5 coming out of its Bastrop, Texas facility. “On a rainy day in Bastrop, Prufrock-5 has left the factory. Will begin tunneling by December 1. Hoping for a step function increase in speed,” the Boring Company wrote.
Prufrock’s quiet disruption
Interestingly enough, the Boring Company also mentioned a key feature of its Prufrock machines that makes them significantly more sustainable and reusable than conventional TBMs. As per a user on X, standard tunnel boring machines are often left underground at the conclusion of a project because retrieving them is usually more expensive and impractical than abandoning them in the location.
As per the Boring Company, however, this is not the case for its Prufrock machines, as they are retrieved, upgraded, and deployed again with improvements. “All Prufrocks are reused, usually with upgrades between launches. Prufrock-1 has now dug six tunnels,” the Boring Company wrote in its reply on X.
The Boring Company’s reply is quite exciting as it suggests that the TBMs from the tunneling startup could eventually be as reusable as SpaceX’s boosters. This is on brand for an Elon Musk-backed venture, of course, though the Boring Company’s disruption is a bit more underground.
