SpaceX could begin testing its Mars rocket in Texas by late 2018, early 2019
On the heels of a successful wet dress rehearsal for Falcon Heavy, SpaceX’s President and COO Gwynne Shotwell spoke briefly about SpaceX for an aerospace conference located at Texas’ Academy of Medicine, Engineering & Science. Ars Technica’s senior spaceflight editor Eric Berger was in attendance and provided a rough outline of live tweets during the first group of presentations.
While the phrasing cannot provide absolute confirmation, Berger summarized a statement by Shotwell suggesting that SpaceX’s Boca Chica, Texas launch site, currently in the early stages of construction, could be ready to host “vehicle tests” as soon as late 2018, early 2019. At this point in time, based on comments from Shotwell and CEO Elon Musk, it can be reasonably assumed that SpaceX’s Texas launch facilities will be dedicated mainly to the company’s interplanetary colonization efforts, and will probably be tailored to support the testing and eventual launches of BFR/BFS.
Some news from Shotwell: Brownsville launch site ready for vehicle tests in late 2018, early 2019. Move to launch site after that.

After nine months of earnest construction and rehabilitation, SpaceX’s LC-40 pad was recently reactivated and has since supported two launches without any major hitches. At the same time, LC-39A in flux in order to support launches of SpaceX’s new Falcon Heavy rocket, the size of which required some concomitant upgrades to multiple ground systems. With both of those major tasks now effectively complete, SpaceX’s pad construction team is free to either refocus their efforts towards Boca Chica. Over the past several months, Boca Chica has seen a gradual but consistent level of development, mainly by way of unaffiliated SpaceX contractors. These changes have been dutifully tracked over the last several years on NASASpaceflight.com forums by a handful of friendly local residents interested in the changes coming to Boca Chica and Brownsville, Texas, a nearby town.

Most significantly, the last several months have seen three major developments. First and most prominently, a permanent facility called STARGATE externally appears complete and its two large radio communication dishes have been installed nearby. The STARGATE facility is a public-private partnership between the University of Texas at Brownsville (now part of University of Texas Rio Grande Valley) and SpaceX, with the academic components focusing on research that SpaceX undoubtedly has interest in: improved orbital spacecraft tracking and communications. Operationally, SpaceX will use the facilities to communicate with and operate its Crew Dragon spacecraft during launches, set to begin with an uncrewed demonstration mission as early as August 2018.
Second, an absolutely massive trolley crane appeared on SpaceX’s land and was eventually housed in an apparently purpose-built shed. The crane dwarfs anything currently used at SpaceX’s launch facilities and is almost certainly a custom-ordered piece of equipment, and thus would be both expensive and explicitly purposeful. What that purpose might be is currently unknown, but it is entirely plausible that the crane is intended to support initial testing (or even limited manufacturing) of SpaceX’s first BFS prototype rockets. This speculation has now been strengthened by Shotwell’s January 11 2018 comment on potential “vehicle tests” occurring at the site within a year or so, and also meshes with a presentation she gave in October 2017 at MIT. It also fits with Elon Musk’s 2017 IAC comments that BFR construction tooling and facilities were respectively already ordered and under construction.

Third and last, the aforementioned SpaceX-following locals observed the early stages of a solar power install beginning on some of SpaceX’s Boca Chica land in late 2017, and also noted that at least some of its contractors were part of Tesla Solar. Plans and permits for solar power were acknowledged as far back as 2014, although at that point the contractor was Solar City (now a part of Tesla). A handful of months later, NASASpaceflight user and all-around awesome guy Nomadd has installed a webcam on a tall pole with a wonderful view of both the solar installation (now nearly completed) and STARGATE. The acre of solar panels can be expected to produce as much as half a megawatt (MW) at peak sun, likely more than enough to offset a considerable amount of the facilities’ electricity usage even after it begins to be see serious use.

Originally announced as an additional Falcon launch facility in 2014, Boca Chica has remained relatively dormant over the last three years, and it is truly exciting to see activity ramping up. There are admittedly significant barriers that will prevent SpaceX from effortlessly repurposing its Boca Chica pad for BFR, a much larger rocket. If SpaceX intends to do that, they will almost certainly need to pass a significantly updated FAA environmental impact review and account for any remediations that might be required. Still, that is a small ask for for Brownsville’s local government and Texas as a whole, both of which have clearly enjoyed and begun to benefit from SpaceX’s presence in the otherwise unknown area. SpaceX is unlikely to give up on Boca Chica in the near term, so long as Ms. Shotwell maintains her belief that it is effectively the perfect location for BFR launches.
Overall, Shotwell’s comments over the last several months and today in particular are increasingly encouraging, and things are likely to only speed up as 2018 progresses, allowing SpaceX to focus more and more of its expertise on BFR, BFS, and its South Texas testing and launch facilities.
Full disclosure: As Shotwell did not specify which vehicle or vehicles could be expected to begin testing in 2018/2019, it is possible that Falcon 9, not BFR, was the statement’s target. This article should be taken with a grain of salt, as it is educated speculation based upon public information from SpaceX executives and Texas contractors. Teslarati reached out to SpaceX for additional information, but the company was unable to comment further on Shotwell’s presentation at the moment.
SpaceX’s Raptor engine family has steadily increased sea-level thrust while simultaneously reducing mass, turning iterative engineering gains into substantially higher performance for the Super Heavy booster. CEO Elon Musk shed more light on how powerful Raptor 4 will be, and it’s pretty crazy.
Raptor 1 delivered 185 metric tons of thrust at roughly 2,080 kilograms, while Raptor 2 raised that to 230 tons while cutting mass to about 1,630 kilograms. SpaceX data for Raptor 3 lists a target of 280 tons at 1,525 kilograms (with further reductions in associated vehicle hardware), while operational flight ratings have been cited near 250 tons.
This morning, Elon Musk stated that Raptor 4 is expected to reach 300 tons of sea-level thrust at roughly the same mass as Raptor 3. Across these versions, thrust has risen by more than 60 percent from the first engines while engine mass has fallen, producing a sharp improvement in thrust-to-weight ratio. This is a true testament to how great SpaceX engineering has been:
🚀 Elon says Raptor 4 will make 300 tons of thrust at sea level at roughly the same mass as Raptor 3.
How far Raptor has come:
Raptor 1: 185 tf, 2,080 kg
Raptor 2: 230 tf, 1,630 kg
Raptor 3: 250 tf, 1,525 kg
Raptor 4: 300 tf33 on Super Heavy = ~9,900 tf, nearly 3x Saturn V https://t.co/HQDswZhyvL

With 33 engines on SuperHeavy, the jump from earlier versions to a 300-ton Raptor 4 would produce roughly 9,900 metric tons of total liftoff thrust, nearly three times the Saturn V’s approximately 3,400 metric tons from its five F-1 engines.
This is not just a larger number on a data sheet, either, as sea-level thrust is the force available the moment the vehicle leaves the pad. This is when it is heaviest and still deep in Earth’s gravity well and dense atmosphere.
Higher levels of sea-level thrust directly improves the initial thrust-to-weight ratio of the full stack. A higher ratio produces faster acceleration off the pad, which shortens the time the rocket has to spend fighting gravity, and gravity losses during the first minute or two of the flight are a major drain on total available delta-v. Every second shaved off of that early climb preserves more propellant energy for reaching orbital velocity or for carrying extra payload.
Because Super Heavy’s engine count is constrained by vehicle diameter and packing density, increasing thrust per engine is the most straightforward way to raise total liftoff performance without redesigning the booster structure or design.
The same-mass target for Raptor 4 is equally important. Holding engine mass roughly constant while raising thrust improves the engine’s own thrust-to-weight ratio and reduces the structural and propellant mass fraction that must be carried solely to support the engines.
Earlier Raptor iterations also simplified or eliminated extensive vehicle-side hardware such as heat shields. These gains compound: more force for less installed mass leaves additional capacity for propellant, payload, or operational margins such as engine-out capability.
For Starship’s architecture, the practical effects are large. Greater liftoff thrust supports heavier vehicles, larger propellant loads, and higher payloads to low Earth orbit, figures SpaceX has targeted in the 100-plus-ton reusable range. That capacity underpins orbital refueling, lunar missions, and eventual Mars cargo and crew flights.
Continued growth in sea-level thrust therefore tightens the gap between theoretical rocket performance and the high flight rates and reusability needed to make large-scale space transport practical.
Tesla has expanded its Tesla Assisted Driving (TAD) suite to its tenth European country, as Latvia joined a growing list of European Union member states authorizing the company’s advanced driver assistance technology.
Tesla Europe announced this morning that the system is now approved in Latvia, with a software rollout to begin soon.
The approval and rollout follow recognition of a provisional European type approval originally granted by the Netherlands’ RDW authority on April 10.
🚨 Latvia has just received approval for Tesla Full Self-Driving (Supervised)
This is the 10th country in the EU to gain approval:
1. Netherlands — 10 April 2026 (original RDW approval)
2. Lithuania — 20 May 2026
3. Estonia — 29 May 2026
4. Denmark — 9 June 2026
5. Belgium — 10 June 2026
6. Slovenia — 7 September 2026
7. Czechia — 21 September 2026
8. Croatia — 29 September 2026
9. Slovakia — 16 October 2026— TESLARATI (@Teslarati) October 26, 2026
Latvia’s Road Traffic Safety Directorate (CSDD) evaluated the Dutch documentation, coordinated with the other national authorities, and reviewed updates from Tesla. These included tightened limits on speed offsets, automatic resets of any manual speed adjustments after each trip, and stronger driver monitoring.
In Europe, the feature is marketed as Tesla Assisted Driving after a recent rule change that labeled the name “Full Self-Driving” as misleading.
The system remains an SAE Level 2 driver assistance tool, not unsupervised autonomy. It can control speed, steering, braking, lane changes, and intersections while following a navigation route. Drivers need not keep their hands on the wheel at all times, yet they must continuously monitor the road and be prepared to intervene immediately.
The sequence of EU recognitions began with the Netherlands in April and continued through Lithuania, Estonia, Denmark, Belgium, Slovenia, Czechia, Croatia, and Slovakia. Most have relied on mutual recognition of the single Dutch provisional approval rather than independent national testing.
These national clearances do not yet constitute bloc-wide authorization. An EU-wide decision requires a qualified majority in the Technical Committee on Motor Vehicles: at least 15 of 27 member states representing 65 percent of the EU population. Larger markets, like Germany, France, and Italy, remain under review, and a vote is expected this December.
However, for Latvian Tesla owners with compatible vehicles and software, the imminent rollout expands access to the supervised system while underscoring that attentive human oversight remains essential.
Tesla expanded its Robotaxi geofence in Houston, Texas, today, enlarging the service area and drawing a new rocket-shaped boundary across the city’s northwestern and central parts.
Although CEO Elon Musk said it was just a coincidence, the expansion seems to be an ode to SpaceX and its potential merger with Tesla.
🚨 Tesla has just expanded its Robotaxi geofence in Houston
It looks a lot like a rocket — we all remember the shape in Austin 🤣 https://t.co/cFOPEuiJ4u
— TESLARATI (@Teslarati) October 26, 2026
The official Tesla Robotaxi account announced the change with the lines “Houston, we have liftoff” and “Bigger service area now live,” pairing them with a map overlay.
The prior white geofence, roughly 25 square miles covering Jersey Village, Harvest Bend, and the Willowbrook corridor along U.S. 290 and State Highway 249, now sits inside a larger blue zone that stretches southeast toward Bellair and closer to central Houston.
Houston’s Robotaxi service launched on April 18, 2026, the same day as Dallas, as Tesla’s first unsupervised public expansion beyond Austin. From the start, the vehicles were Model Ys running without anyone in the front seats, booked through the dedicated Tesla Robotaxi app and open to the public inside the geofence.
Trackers measured the initial zone at about 25 square miles; by late September it had not grown substantially. Community and registry data indicated a modest local fleet of unsupervised Model Ys, while dozens to nearly 200 Cybercabs, the purpose-built, steering-wheel-free two-seaters, have been spotted staging and testing in Houston lots, though public Cybercab rides remain limited to Austin for now.
Across the broader Robotaxi program, Tesla began public Robotaxi rides in Austin in June 2025, as a small geofence and vehicles with safety monitors became available for a ride-hailing service. Later on, Tesla removed the monitors and steadily expanded the service area until it covered most of the Austin metro area.
Unsupervised Robotaxi services now run in six cities: Austin, Dallas, Houston, Miami, Orlando, and Tampa. Cumulative driverless miles reported by the company have reached several million. The Cybercab entered public service in Austin in early September 2026 and has scaled rapidly there. The company has also said that Dallas is next for Cybercab rides in November, with further cities and 24/7 hours targeted by year-end, plus fleet-operator sales of the vehicle.
Waymo also operates a fully driverless service in Houston, which has been open to the public since August of this year.
The Houston expansion continues Tesla’s pattern of starting with tightly controlled validation zones before widening coverage as real-world data accumulates, while the rocket motif on the map underscores the company’s habit of injecting visual flair into its autonomy rollout.
Riders inside the new boundary can request unsupervised Model Y trips in the Robotaxi app; exact operating hours and further Cybercab availability remain subject to app updates and company statements.
