SpaceX nails reused booster launch, Falcon Heavy’s maiden flight days away

Published

on

Despite a brief 24-hour delay due to weather and minor mechanical issues, SpaceX recycled the launch opportunity and completed the mission on Wednesday afternoon, January 31. Tasked with carrying GovSat-1 to orbit, the reused Falcon 9 rocket (Booster 1032) performed flawlessly and as expected, although the stage was expended. Launch directors confirmed just before the end of the live webcast that the communications satellite, a public-private partnership between SES and Luxembourg, was placed into a good orbit a few minutes before it separated from Falcon 9’s second stage. The mission marks SpaceX’s second successful launch of 2018, its first reused flight of the year, and the last launch before Falcon Heavy’s inaugural flight – currently scheduled for Tuesday, February 6.

Perhaps most intriguingly (or at least uniquely), the to-be-expended booster was still seen outfitted with both grid fins and landing legs at the launch pad, the new legs a stark white against the dark and sooty backdrop of the Falcon 9’s recycled booster. While SpaceX’s webcast host very explicitly stated at least three times that the first stage was not going to be recovered, careful listeners may have still caught snippets of the launch and recovery directors announcing different milestones as Falcon 9 S1 landed softly in the Atlantic Ocean. Similar to the recovery operations after the launch of Iridium-4 in December 2018, S1 flew as if it were landing aboard a drone ship, although in the case of this launch that theatricality extended even to landing legs.

While it may seem quite odd that SpaceX would choose to expend an entire, recoverable rocket, it is presumed that SpaceX is simply choosing to rid itself of a stock of older boosters incapable of flying more than once or twice – preparing for the introduction of the highly reusable Block 5 of Falcon 9, in other words. As stated by the webcast host, a SpaceX engineer, the company’s goal is for boosters to last “tens of launches in the short term, and hundreds or thousands of launches in the long term.” It is worth remembering that expending rocket boosters in the ocean (or even over land for Russia and China) is the status quo of all non-SpaceX rockets, and SpaceX has only just begun to perfect booster recovery and reuse – the first successful ocean recovery was completed less than two years ago. The very fact that it already feels odd or even wrong to “throw away” hardware into the ocean after launch is a testament to just how rapidly SpaceX have changed both the figurative and literal paradigms of orbital rocketry, and it is only a matter of time before the eminently persistent company ends the practice of expendable launches internally, if not globally.

Up next, Falcon Heavy

After yet another successful mission for SpaceX, the company’s Florida efforts will now briefly focus on the imminent inaugural launch of Falcon Heavy, the company’s newest and largest rocket. Loosely penciled in for liftoff on Tuesday, February 6, the massive vehicle will become the most powerful and capable operational rocket in the world, comparable only to the likes of NASA’s Saturn V and Space Shuttle, as well as the Soviet Union’s short-lived Energia. Regardless of its place against a historical backdrop of massive state-funded rockets, Falcon Heavy will by default become the most powerful commercial launch vehicle ever developed, and that title will almost certainly remain uncontested until 2020 at the absolute earliest. If or when the first and smallest version of NASA’s SLS rocket launches, likely also no earlier than 2020, the space agency may well take the crown back for a brief year or so. Regardless, SpaceX will likely be regularly launching Falcon Heavies and nearing the tail end of the development and testing of its much larger BFR rocket and spaceship.

Falcon Heavy will be the clearest progress yet towards such a massive rocket, and will provide SpaceX with invaluable experience and expertise as the only private company to ever operate a super heavy-lift launch vehicle (SHLLV). After a solid four weeks of near-constant testing, bug-fixing, and retesting, Falcon Heavy just days ago completed its first static fire, marking the first point in its history that all 27 of its first stage engines were simultaneously ignited. The data produced by that crucial test was apparently satisfactory, and Elon Musk just yesterday reiterated that the vehicle’s first launch was still targeting February 6.

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

Published

on

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.
