On Sunday morning, SpaceX began the process of installing the last prefabricated section of Starship’s skyscraper-sized ‘launch tower’ around the same time as startup Blue Origin kicked off a preflight briefing for its first crewed suborbital launch.

Though both events are almost entirely unconnected and have no immediate impact on each other, the simultaneity almost immediately triggered comparisons between one of the most important media briefings in Blue Origin’s 21-year history and an average busy day at SpaceX’s South Texas Starship factory and launch site. Almost exclusively funded by Amazon founder and CEO Jeff Bezos since it was founded in September 2000, around two years before SpaceX, Blue Origin is on the cusp of its first crewed launch less than two weeks after Virgin Galactic completed its first fully-crewed test flight above 80 km (~50 mi).

Approximately 600 miles southeast of Blue Origin’s Van Horn, Texas launch and test facilities, in a different corner of the vast state, SpaceX was preparing for the latest in a long line of steps towards the completion of an orbital launch site for Starship – potentially the first fully reusable orbital rocket ever built.

First revealed more than three months ago in a cryptic post from owner Jeff Bezos, Blue Origin is scheduled to launch passengers on its New Shepard rocket for the first time ever, marking the end of an extraordinarily long development period. Designed to be fully reusable, New Shepard is a small single-stage rocket powered by one liquid hydrogen and oxygen-fueled BE-3 engine capable of producing approximately 500 kN (110,000 lbf) of thrust at liftoff. Designed exclusively for the purpose of ferrying a few tourists above a mostly arbitrary 100 km (~62 mi) line separating Earth’s atmosphere and “space,” New Shepard is about the same diameter as SpaceX’s Falcon 9 and Falcon Heavy rockets but is just 15m (~50 ft) tall.

The small rocket launched for the first time in April 2015 and reached an apogee of ~94 km but instability ultimately destroyed the first New Shepard booster during its first landing attempt. Blue Origin successfully launched and landed New Shepard on its next test flight in November 2015, culminating in Bezos’ infamous “Welcome to the club!” comment after SpaceX successfully recovered a Falcon 9 booster for the first time one month later.

As of July 2021, Blue Origin has completed just 15 New Shepard test flights – 14 of which were fully successful – in six years. In the same period, SpaceX successfully recovered an orbital-class Falcon 9 booster for the first time, reused a Falcon booster on a commercial satellite launch, debuted Falcon Heavy, reused several orbital Cargo Dragon capsules three times each, debuted Crew Dragon, became the first company in history to launch astronauts, completed its first operational astronaut launch for NASA, hopped three Starship prototypes, flew five Starship prototypes to 10-15 km, successfully landed four Raptor-powered Starship prototypes, rolled out Starship’s first completed booster prototype, completed more than 100 successful orbital launches, flown the same Falcon 9 booster ten times (versus New Shepard’s record of seven flights), reused orbital-class boosters 68 times, created the world’s largest satellite constellation, and far, far more.

Along those lines, on Saturday, July 17th, SpaceX teams attached a massive crane to the seventh prefabricated section of a ‘launch tower’ that could eventually support Starship and Super Heavy stacking – and maybe even catch ships and boosters. On Sunday, not long after daybreak and about an hour before Blue Origin’s New Shepard-16 preflight briefing, that tower section lifted off under the watchful eye of several unofficial cameras operated by NASASpaceflight, LabPadre, and others. By the end of Blue Origin’s briefing, most of which involved executives or senior employees reading from scripts and none of which offered a look at actual flight hardware or “astronaut” preparations, the eighth launch tower section was mostly in place, creating a structure some 135m (~440 ft) tall.

By the end of NASASpaceflight.com’s unofficial six-hour stream, the outlet’s excellent and unaffiliated coverage of SpaceX erecting part of a relatively simple tower for the seventh time had been viewed more than a quarter of a million times. By the end of Blue Origin’s official preflight briefing for a crewed launch set to carry the richest person on Earth, the company had accrued around 20,000 views on YouTube.

Some might see ten times as many viewers flocking to an unofficial live stream of fairly mundane SpaceX construction over a briefing for the first crewed launch of a fully-reusable suborbital rocket and scoff. For those who watched both broadcasts, it’s likely less than shocking that spaceflight and rocket fans almost universally sided with a livestream showing something – anything! – happening over what amounted to a camera pointed at five people reading (mostly stale) statements off of teleprompters.

Barely 24 hours away from Blue Origin’s most significant launch ever, the company – save for a few low-res clips from Jeff Bezos – has yet to share a single new piece of media highlighting the mission’s actual New Shepard rocket, crew capsule, astronaut preparations, flight suits, launch pad, or any of the other dozens of things most spaceflight fans – and people in general – tend to get excited about. For whatever reason, Blue Origin has also worked with Texas to shut down the only quasi-public viewing area less than 10-20 miles away from New Shepard’s launch pad despite never having done so in 15 test flights.

SpaceX, on the other hand, may not have always been a perfect neighbor in Boca Chica but the company has mostly accepted the buzzing, near-continuous presence of spaceflight fans and members of the media who come to South Texas to see Starbase in person. More recently, SpaceX has actively let at least two media outlets (NASASpaceflight and LabPadre) install and operate several robotic cameras overlooking Boca Chica’s Starship factory and pad.

It’s impossible to condense it into one or two simple differences but it’s safe to say that SpaceX’s relative openness and a general willingness to engage with media and let public excitement and interest grow uninterrupted (when possible) is part of the reason that mundane SpaceX goings-on can accumulate a magnitude more interest on unofficial channels than an official briefing for the most important event in Blue Origin’s history.

Elon Musk

How SpaceX Is raising Raptor’s sea-level thrust while holding engine mass steady

Published

on

Credit: SpaceX

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:

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 Assisted Driving expands to tenth EU country

Published

on

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’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.

Tesla starts showing how FSD will change lives in Europe

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 expands Robotaxi geofence in Houston with an ode to SpaceX merger

Published

on

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.

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.
