SpaceX Mars rocket test site receives first huge rocket propellant storage tank
SpaceX has delivered one of the first undeniably rocketry-related pieces of hardware to its prospective Boca Chica test and launch facility in South Texas, this time in the form of a massive 100,000-gallon liquid oxygen tank now stationed adjacent to the company’s ~600 kW Tesla solar and battery array.
In a statement provided to local paper Valley Morning Star, SpaceX spokesperson Sean Pitt filled in a few of the details and confirmed that the LOX tank had been delivered to Boca Chica as part of an ongoing effort to ready the site for initial testing – and eventually launches – of an unspecified “vehicle”
“Delivery of a new liquid oxygen tank, which will be used to support propellant-loading operations during launch and vehicle tests, represents the latest major piece of launch hardware to arrive at the [South Texas] site for installation.” – SpaceX
The official SpaceX statement may not have explicitly stated that the aforementioned “vehicle” was something other than Falcon 9 or Heavy, but it can be all but guaranteed that the testing and launching described refers to the company’s next-generation Mars rocket, a completely reusable architecture known as BFR.

A slow burn in South Texas
Over the past 6-9 months, SpaceX CEO Elon Musk and President/COO Gwynne Shotwell have repeatedly spoken on the subject of SpaceX’s South Texas ambitions, lending unambiguous credence to the idea that the Boca Chica rocket facility will be almost exclusively dedicated to testing BFR’s first flightworthy spaceship prototypes, beginning with a series of familiar suborbital “hops”.

In the early days of SpaceX’s Falcon 9 reusability program, the company completed several different phases of short flights (“hops”, hence the Grasshopper label) of a development version of a Falcon 9 booster, ranging from purely vertical jaunts just above the pad to 1000+ meter cross-range maneuvers, tests that ultimately culminated in SpaceX’s extraordinarily reliable Falcon 9 and Heavy booster recovery capabilities. Something similar – albeit somewhat more ambitious – is planned for BFR, starting with a prototype of the upper stage (spaceship). Musk described these plans in more detail in an October 2017 Reddit AMA:
Will we see BFS hops or smaller test vehicles similar to Grasshopper/F9R-Dev?
A (Elon): A lot. Will be starting with a full-scale Ship doing short hops of a few hundred kilometers altitude and lateral distance. Those are fairly easy on the vehicle, as no heat shield is needed, we can have a large amount of reserve propellant and don’t need the high area ratio, deep space Raptor engines.
Speaking a bit less than five months later after the stunningly successful debut of Falcon Heavy, Musk expanded further on the BFR test program, reiterating that spaceship hop testing would “most likely … happen at our Brownsville [South Texas] location,” perhaps as early as 2019.
“We’ll do flights of increasing complexity. We really want to test the heat shield material… like fly out, turn around, accelerate back real hard, and come in hot to test the heat shield.”

Musk also noted that he expected the first full-up orbital launch with both the Booster (BFB) and Spaceship (BFS) could happen as soon as 2021 or 2022. Shotwell, on the other hand, stated in early 2018 and again more recently that she believed BFR could begin its first orbital test missions as early as 2020, an extraordinarily rare moment where the typically pragmatic executive appeared to be more confident than Musk, often lambasted for his reliably over-optimistic timelines. About a month later, Musk’s comments were much more closely aligned with Shotwell’s BFR timeline estimates, and he enthusiastically said that that spaceship hop tests would likely begin within the first half of 2019.
The unambiguous arrival of a rocket propellant storage tank – confirmed officially by SpaceX – strongly suggests that activity is about to seriously pick up speed in Boca Chica for the first time in a year and a half, paving the way for full-scale hop tests of the first Mars spaceship prototype perhaps less than a year from today.

Tesla Cybercab gets huge nod of support from Texas DOT official
The Tesla Cybercab got a huge nod of support from a Texas Department of Transportation official, who said the all-electric ride-hailing vehicle is “a tangible example of how quickly our transportation system is evolving.”
The Cybercab was present at the Texas Department of Transportation’s Texas Innovation Invitational, an event held each year that allows innovative companies to showcase advancements in transportation.
Tesla Cybercab specs revealed: range, curb weight, range ratings, and more
Marc Williams, the Texas Department of Transportation’s Executive Director, sat in a Cybercab and shared his thoughts in an extensive post on LinkedIn.
Williams’s comments show how Tesla, with its Cybercab, is leading the charge of passenger travel and how it’s changing so rapidly. He notes the absence of traditional driving controls as a telltale sign that the Cybercab is a catalyst for major automotive change, taking controls from drivers and turning them into full-time passengers.
“Observing this vehicle firsthand–from its design and butterfly doors to the cargo trunk configuration–provides a tangible example of how quickly our transportation system is evolving. Sitting inside the cabin, the complete absence of traditional driver controls underscores a significant shift in mobility and vehicle design. No steering wheel, no accelerator, no brake. Only a single touchscreen monitor.”
Tesla has had a great relationship with the State of Texas, especially with its Robotaxi ambitions. Currently, Texas has Tesla Robotaxi operating in multiple cities: Dallas, Austin, San Antonio, and Houston. The company’s main manufacturing plant is also located just outside Austin, and Tesla moved its headquarters to the state several years ago.

The Cybercab is a purpose-built, fully autonomous, two-passenger Robotaxi vehicle designed specifically for ride-hailing services. Tesla has said for years it would be built without a steering wheel or pedals present, although there is still quite a bit of debate among the community regarding that potential.
Earlier this week, we received official word that the EPA had provided the Cybercab with a Certificate of Conformity, giving Tesla permission to enter the vehicle into the chain of public commerce. It is officially ready for roads.
The big question for Tesla remains: Can it solve self-driving before the steering-wheel-less Cybercab officially enters production?

The Boring Company just doubled its tunneling power in Nashville
The Boring Company’s Prufrock MB2 is commissioned and ready to mine beneath Nashville’s streets.
The Boring Company’s second tunnel boring machine, Prufrock MB2, is officially ready to dig in Nashville. The company confirmed the news on X, posting: “Prufrock-MB2 is ready to mine in Nashville! MB2 commissioning is complete, including the brief 11 rpm rotation shown here. Will MB2 catch up to MB1, who had quite the head start? And Prufrock-MB3 ships in August!”
MB2 arrives with meaningful improvements over its predecessor. Lessons learned from the launch and operation of MB1 have already been applied to MB2 to improve efficiency and prepare the machine for launch.
Traditional tunnel boring machines operate in a stop-and-go cycle, digging roughly five feet, halt, erect precast concrete segments to line the tunnel wall, then resume. That repeated interruption is one of the main reasons conventional tunneling is slow and expensive. Prufrock is designed to install the tunnel liner simultaneously with mining, eliminating the need to stop every five feet. The machine also skips the need for excavated launch pits. Prufrock arrives on a truck, tilts down, and launches into the ground within 24 hours. And when the tunnel is complete, it emerges from the ground and drives to its next launch site on a trailer, eliminating the need for expensive cranes or pit excavation. The machine is also fully electric and runs with zero people in the tunnel during normal operations, controlled remotely from a surface operations center.

It won’t be long before we hear of another major update on The Boring Company’s Music City Loop project – a planned underground transit network beneath Nashville that would move passengers in electric vehicles through a series of tunnels at highway speeds, and bypassing surface traffic entirely. Nashville was selected in part because of its strong rock conditions that suits the Prufrock machines well, and relatively less regulatory hurdles.
Progress has been steady on multiple fronts. All 37 permits and approvals required ahead of tunneling have been obtained, out of 45 total. Key wins include a fully executed TDOT tunnel permit authorizing 25 miles of tunnel, unanimous airport authority approval for a Nashville International Airport station, and the city’s first residential station agreement serving downtown tower residents.
With MB1 already tunneling, MB2 now commissioned, and MB3 shipping in August, Nashville is becoming something of a live proving ground for scaled tunnel boring. The broader ambition is not limited to one city. The Boring Company’s stated goal is to make underground transportation a practical alternative to surface roads across major metro areas. Nashville is one of many cities, including a successful Las Vegas tunnel system, where that idea is being put to the test at real speed.

Tesla urges New Jersey owners to oppose new bill that could block Robotaxi
Tesla has launched a direct campaign targeting its customers in New Jersey, sending emails that warn of pending legislation that could effectively block true driverless technology in the state.
The email focuses on Senate Bill S.1677 and Assembly Bill A.3968, measures intended to create a three-year autonomous vehicle pilot program but laden with requirements that Tesla argues make unsupervised Robotaxis impossible.
Tesla is sending out this email to New Jersey Tesla owners, warning them that NJ could block autonomous vehicles, and to take action.
“Proposed legislation moving through Trenton right now would impose restrictions so severe that true driverless deployment would remain illegal.… pic.twitter.com/2bmY646AUL

According to the email, the bills impose “restrictions so severe that true driverless deployment would remain illegal.” Specific hurdles include mandates for human safety drivers during operations, multimillion-dollar insurance minimums, reportedly $5 million, and thresholds like 100,000 miles of demonstrated safe autonomous driving before any driverless approval.
Tesla contends these are arbitrary barriers that ignore real-world performance data and favor entrenched competitors over innovative technologies like its Full Self-Driving (FSD) system.
The push comes as Tesla has started expanding Robotaxi operations in states like Texas, where unsupervised vehicles are already providing rides in several cities. New Jersey, by contrast, risks falling behind. The company highlights in the email communication that more than 94 percent of serious crashes result from human error, meaning impairment, distraction, or fatigue. These are all problems that Robotaxis eliminate entirely.
In 2025, New Jersey recorded 582 traffic deaths, underscoring the human cost of delayed adoption.
Tesla’s outreach stresses the transformative potential of robotaxis. For families, they could offer safer school runs without drowsy or distracted drivers. For seniors and people with disabilities, robotaxis promise independence and reliable mobility.
In areas with limited public transit, they could deliver affordable, on-demand transportation, reducing congestion, emissions, and overall transportation costs. Economically, the company warns that restrictive rules could cost New Jersey jobs, innovation investment, and billions in potential growth as autonomous ride-hailing scales elsewhere.
Supporters of the legislation, including Sen. Andrew Zwicker, describe the pilot as a cautious framework with strong safety oversight, including incident reporting, expert task forces, and restrictions in sensitive zones like school areas. They view it as balancing innovation with public protection.
Tesla and pro-AV advocates counter that the bill lacks technology neutrality, creates insurmountable entry barriers for commercial deployment, and prioritizes process over outcomes — effectively functioning as a de facto ban on services like Robotaxi.
This latest clash echoes Tesla’s past battles in New Jersey over direct vehicle sales. The email directs owners to Tesla’s advocacy platform, where they can send customized messages to legislators calling for amendments: outcome-based safety standards, open competition, and clear pathways for fully driverless commercial operations.
As hearings approach, Tesla’s campaign frames the issue as a choice between protecting the status quo and embracing life-saving progress. With robotaxi technology already proving itself in permissive states, New Jersey owners are being asked to ensure their state doesn’t lock out the future of transportation.
