NASA has formally given SpaceX permission for Crew Dragon’s second launch – a crucial test flight that should be the last before SpaceX launches NASA astronauts to the International Space Station (ISS) for the first time ever.

Known as its In-Flight Abort (IFA) test, Crew Dragon will attempt to escape a Falcon 9 rocket while airborne, a feat that CEO Elon Musk says will almost certainly destroy the rocket in the process. Technically speaking, NASA and SpaceX completed what is known as a Launch Readiness Review (LRR) sometime on Thursday, allowing SpaceX to proceed with launch preparations. By all accounts, Crew Dragon’s IFA test will likely be one of the most spectacular SpaceX launches ever, given that it is all but guaranteed to result in the intentional in-flight failure of a massive Falcon 9 rocket – “destroyed in Dragon fire” according to Musk.

Thanks to a much smoother launch flow compared to Crew Dragon’s Demo-1 orbital launch debut on Falcon 9, SpaceX’s newest Crew Dragon capsule is scheduled to lift off from Kennedy Space Center Launch Complex 39A (KSC LC-39A) as early as 8 am EST (13:00 UTC), Saturday, January 18th. The In-Flight Abort test will likely be one of Crew Dragon’s most challenging hurdles yet but success would be a major boon for the spacecraft’s demonstrated safety. While both Boeing and SpaceX will ultimately ferry NASA astronauts to and from the ISS, only SpaceX chose to prove Crew Dragon’s in-flight abort capabilities in the real world.

Effectively condemned to destruction to support a greater cause after a productive life, Falcon 9 Block 5 booster B1046 rolled out to Pad 39A – Crew Dragon mounted atop it – on January 16th after successfully performing its last routine static fire on the 11th. As previously discussed on Teslarati, B1046 is the first Falcon 9 Block 5 booster completed by SpaceX and is thus also the oldest flightworthy rocket in the company’s substantial fleet.

“After becoming the first SpaceX booster to launch three times in December 2018, B1046 spent several months at SpaceX’s Hawthorne, CA factory undergoing inspections and refurbishment. At some point, SpaceX assigned the thrice-flown booster to support Crew Dragon’s In-Flight Abort (IFA) test – effectively a death sentence – and shipped the booster to Florida, where it publicly appeared for the first time in months on October 3rd, 2019. Given that four more Falcon 9 boosters have now successfully performed three (or even four) orbital-class launches each, B1046’s now-imminent demise is certainly disappointing but remains extremely pragmatic.”

As such, there is arguably no better booster for SpaceX to expend even if its loss is still less satisfying than a successful post-launch landing. In fact, aside from NASA’s prematurely-retired Space Shuttle, the entire history of orbital-class rocketry has effectively operated on the assumption that it’s both normal and necessary for rockets to be almost entirely expendable.

Only by sheer force of will has SpaceX turned that assumption on its head, making the act of expending Falcon 9 or Falcon Heavy boosters feel suddenly morose. Even then, the practice of propulsively landing orbital-class boosters is scarcely four years old, while reusing those boosters has been ongoing for less than three years. As such, B1046’s demise should be enjoyed for what it ultimately is: the spectacular retirement of a rocket that has already helped launch three separate payloads to orbit.

Perhaps even more importantly, B1046’s sacrifice should – if things go as planned – also pave the way for Crew Dragon to launch its first NASA astronauts into orbit just a few months from now. For the test to be successful, however, Crew Dragon will have to perform an extremely precise string of maneuvers – the failure of any one of which could potentially lead to the spacecraft’s destruction.

“Traveling as fast as Mach 2.5 (860 m/s) at an altitude of 28 kilometers (17 mi), Crew Dragon will ignite its abort thrusters and attempt to escape, the very act of which will likely hammer the spacecraft’s windward surfaces with an extra dozen or so metric tons (~25,000 lb) of aerodynamic pressure. Crew Dragon C205 could thus find itself traveling almost Mach 3 (more than a kilometer per second) moments after separating from Falcon 9, eventually reaching an apogee of almost 75 km (45 mi), after which it will reenter the bulk of Earth’s atmosphere and have to deploy an array of parachutes to ensure a gentle Atlantic Ocean splashdown.”

Unfortunately, Crew Dragon escaping a supersonic Falcon 9 also means that that same Falcon 9 – basically a thin, flexible tube designed to be as light as possible – will meet a supersonic blast of air the moment Dragon’s SuperDraco abort thrusters ignite. A bit like if a hurricane on all kinds of meteorological steroids just sort of punched a soda can for fun, that airstream will almost certainly obliterate Falcon 9’s sacrificial upper stage into a sort of aluminum snow, quickly revealing – and likely then destroying – B1046’s carbon fiber interstage.

The rest of the thrice-flown Falcon 9 booster is also liable to break up after that supersonic punch. In fact, SpaceX engineers are so confident in B1046’s imminent demise that the booster will have neither landing legs or grid fins come launch. In a best-case scenario, if, against all odds, B1046 survives Dragon’s escape, the intact booster will subsequently impact the Atlantic Ocean at terminal velocity and become a nice, artificial reef off the coast of Florida. Stay tuned for updates from Teslarati and photographers Jamie Groh and Richard Angle as Falcon 9 B1046’s demise inches ever closer.

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.
