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 is going to let you guide Full Self-Driving with Grok in 3 months, CEO Elon Musk confirmed on X.
The response from Musk, which revealed Tesla plans to allow drivers to effectively control the car and its navigation more explicitly using Grok, puts the feature for about September.
A Tesla owner said that Full Self-Driving is great, but owners should be able to “converse with Grok like we can with an Uber driver.” She then used examples like, “Grok, turn right here,” and “Drop us off right here, we’ll walk due to traffic,” and finally,” Drop at entrance first, then park far away.”
Coincidentally, the final piece of dialogue would also mean features like Banish are potentially on the way soon.
This functionality will be there in about 3 months or so
— Elon Musk (@elonmusk) June 18, 2026
Banish is also referred to as “Reverse Summon,” and would enable the car to self-park while dropping occupants off at their destination.
This would be a great way to improve the overall experience while supervising FSD. Navigation is already a major painpoint that many owners complain about. Manual overrides when a maneuver is requested or canceled (like using the turn signal stalk to override a navigation route), do not always work.
The feature could be especially useful in street parking scenarios in a city, where spots are sometimes tough to come by. Many of us who grab dinner in a more populated area will park a street or two over from wherever we’re going, because sometimes you know that’s the best you will get. If a driver using FSD could say, “Hey Grok, turn right here on Queen St. and park in that open spot on the right,” it could save a lot of confusion FSD might have on its own.
Musk teased that a similar feature was “coming” back in February:
Tesla Full Self-Driving set to get an awesome new feature, Elon Musk says
It is certainly surprising that Tesla is doing it at this point. The company’s more recent moves have been more evident of taking control and inputs away from humans and putting them in the AI’s hands more frequently. The biggest example of this was taking away Max Speed in AI4 cars, giving us Speed Profiles, and not having any input on the fastest speed the car will travel.
Of course, giving navigation preferences to Grok is availble already in Teslas, but not at the drop of a hat. Instead, you can suggest a certain route at the beginning of your drive.
Here’s an example of that from December:
🚨🏈 I am taking my parents and Fiancee to the @Ravens game next weekend and asked @Grok to help me route my @Tesla through a specific neighborhood to reach the correct Lot we will park in.
This is a great example of the new @grok nav integration with the Tesla Holiday Update: pic.twitter.com/rPp4I7q8Yv
— TESLARATI (@Teslarati) December 13, 2025
Finally, the original post that Musk responded to mentioned a parking preference after dropping off the occupants, which describes the Banish feature that Tesla has teased for years.
We’re not sure if Musk was responding more to the ability to guide the car with Grok, or whether he also was including Banish in the three-month prediction timeframe.
A close-up image of a Cybercab engineering vehicle in Peabody, Massachusetts, reveals a compact triangular side repeater camera housing equipped with an integrated washer mechanism.
This seemingly small hardware addition could prove to be one of the most critical components for achieving reliable, unsupervised Full Self-Driving (FSD) — not just for the dedicated Robotaxi but potentially for existing AI4-equipped vehicles as well.
The washer system’s importance cannot be overstated in Tesla’s vision-only autonomy approach. Cameras are the sole sensory input for the neural networks powering FSD, constantly interpreting the environment for safe navigation. In real-world conditions, however, lenses quickly accumulate rain, snow, mud, dust, or road spray.
Many of us Tesla owners, especially those who deal with any sort of winter weather at all, know the all-too-common alert that pops up when cameras are obstructed:
Even brief obstructions can drop perception confidence, trigger safety disengagements, or force the vehicle to pull over, although these are relatively rare. Instead, most of the time, the camera will need a wipe from the owner next time they stop the car.
But unlike human drivers who can manually clear their view, a Robotaxi operating 24/7 without a steering wheel or mirrors must maintain pristine vision autonomously. The Cybercab’s side repeater washer delivers targeted cleaning bursts precisely where needed for merging, lane changes, and blind-spot monitoring — functions that demand uninterrupted visibility from the external cameras:

— Tobias Goebel (Unsupervised) (@tpgoebel) June 17, 2026
This hardware directly tackles a known pain point in current FSD deployments. Owners frequently report camera-related alerts during inclement weather, which is understandable, but needs to be solved for a true autonomous experience.
For a production Robotaxi fleet aiming for high utilization and minimal downtime, robust washer systems represent a foundational reliability upgrade; essentially, they’re a must-have. Early sightings suggest the design may extend to rear cameras as well, creating a comprehensive cleaning architecture that keeps the entire vision suite operational in harsh environments.
Without it, even the most advanced neural nets struggle when their “eyes” are compromised.
What Does This Mean for AI4 Cars?
This Cybercab detail raises timely questions for AI4 cars already on the road. While Hardware 4 delivers superior compute and camera resolution compared to earlier versions, production models typically lack dedicated side and rear washers. Tesla has included them on Model Y robotaxis that it is using in the fleet:
Tesla Robotaxi has a highly-requested hardware feature not available on typical Model Ys
As Tesla refines unsupervised FSD for broader release, the gap in environmental resilience becomes evident. Software improvements can help mitigate issues, but they cannot fully replace physical cleaning in heavy rain or muddy conditions. Analysts and owners increasingly speculate that AI4 vehicles may eventually require similar washer retrofits — or a future AI4.5 variant — to match the Cybercab’s all-weather readiness and support the same level of autonomy.
As testing progresses, the Cybercab’s washer mechanism highlights Tesla’s pragmatic focus on real-world robustness. It may well become the hardware piece that determines how quickly and reliably FSD scales from prototypes to everyday vehicles.

Elon Musk just upped his Tesla stake further fueling SpaceX merger conversation
Elon Musk just collected a $116 billion Tesla payday and the timing is eye-opening
Elon Musk quietly collected one of the largest single-transaction paydays in corporate history on Monday. A Form 4 filed with the SEC on June 17, 2026 disclosed that Musk exercised 303,960,630 Tesla stock options from his 2018 compensation package, with the transaction dated June 16. No shares were sold on the open market.
The numbers are straightforward but striking. Musk exercised the options at a split-adjusted strike price of $23.34, with Tesla closing at $404.66 that day, putting the spread at $381.32 per share and generating roughly $115.9 billion in paper gains in a single transaction. To cover the exercise cost, Tesla withheld 17,531,857 shares through a net share settlement, meaning Musk paid nothing out of pocket.
For perspective, in 2018, Elon Musk’s award was originally approved by Tesla shareholders on March 21, 2018, and structured entirely around performance milestones that many analysts at the time called unreachable. Every tranche eventually vested. The original grant covered 20,264,042 shares at $350.02, which after Tesla’s 5-for-1 split in 2020 and 3-for-1 split in 2022 adjusted to 303,960,630 shares at $23.34. A Delaware court rescinded the award in January 2024, ruling the board was conflicted. As Teslarati reported, Tesla shareholders voted to ratify the package anyway in June 2024 by a wide margin. The Delaware Supreme Court reversed the decision in December 2025, finding full cancellation too extreme, and Tesla’s board signed an Implementation Agreement on April 21, 2026 to formally deliver the shares.
The Tesla and SpaceX merger everyone is talking about is quietly building
The timing and structure of the Form 4 filing carries more weight than a routine stock option exercise typically would. Musk exercised his 2018 Tesla award on June 16, a week into SpaceX completing its IPO and trading publicly, and giving SpaceX a public market valuation and share currency for the first time in the company’s history. A stock-for-stock merger between two companies requires the acquiring entity to have tradeable shares it can offer to the target’s shareholders, and SpaceX now has exactly that. At the same time, Musk just increased his direct Tesla voting power to approximately 20%, giving him greater influence over any shareholder vote that a merger would require. The restricted shares he received cannot be sold until 2033, which removes any near-term incentive to cash out and instead positions this stake as long-term structural collateral in a deal. Additionally, Musk’s two companies are already deeply intertwined through shared semiconductor fabrication at their joint TERAFAB facility in Austin, cross-company supply chain transactions, and Tesla’s $2 billion investment in xAI prior to the SpaceX-xAI merger.
Wedbush analyst Dan Ives has publicly placed the odds of a Tesla and SpaceX combination at 80% to 90% by early 2027. The Implementation Agreement that made Monday’s exercise possible was signed on April 21, 2026, roughly two months before the SpaceX IPO closed. That sequencing, building Musk’s Tesla ownership to its highest point ever immediately before SpaceX gains the public currency needed to acquire it, is either an extraordinary coincidence or a carefully staged foundation for the largest corporate merger in history.
