SpaceX’s Mr. Steven preparing for first Falcon 9 fairing catch attempt in months
SpaceX recovery vessel Mr. Steven has spent the last several weeks undergoing major refits – including a new net and arms – and testing the upgraded hardware in anticipation of the vessel’s first fairing catch attempt in more than four months.
Required after a mysterious anomaly saw Mr. Steven return to Port in February sans two arms and a net, the appearance of a new net and arms guarantees that SpaceX is still pursuing its current method of fairing recovery. Above all else, successfully closing the loop and catching fairings could help SpaceX dramatically ramp its launch cadence and lower costs, especially critical for the affordable launch of the company’s own Starlink satellite constellation.
The Saga of Steven
For a few months of 2019, it was entirely conceivable that SpaceX had all but given up on catching Falcon fairings, having spent the better part of 2018 without a single success during both post-launch and experimentally controlled catch attempts. Admittedly, a year may feel like a huge amount of time, but SpaceX has demonstrated just how hard the reliably successful recovery of orbital-class rocket hardware really is.
Depending on how one examines the history of Falcon 9, it took SpaceX anywhere from ~30 and ~70 months and either 7 or 9 failed recovery attempts before the first Falcon 9 booster successfully landed in December 2015. Excluding helicopter-based fairing drop tests, Mr. Steven and SpaceX’s fairing recovery team have made five attempts to catch fairings in the vessel’s net after Falcon 9 launches. All have been unsuccessful, with the closest miss reportedly landing in the Pacific Ocean just 50 meters away from Mr. Steven’s massive net.
In January 2019, Mr. Steven sailed ~8000 km (5000 mi) from Port of Los Angeles to Port Canaveral, passing through the Panama Canal. For unknown reasons, during a trip out to sea to catch a Falcon 9 fairing in February, Mr. Steven abruptly turned around early and arrived in port missing two of four arms, four of eight booms, and the entirety of its custom net. The remaining arms/booms were removed and the vessel spent roughly three months docked with just a handful of excursions.
In late May, technicians rapidly installed new arms and booms, as well as a new (and blue) net, bringing about the end of months of inactivity. Mr. Steven has yet to venture beyond the safety of Port Canaveral since its new ‘catcher’s mitt’ was installed, but SpaceX has been testing the new setup by repeatedly lowering a Falcon fairing half into the net. It’s too early to raise expectations but it seems plausible that the iconic recovery vessel will be ready to attempt its first fairing catch in ~4 months as part of Falcon Heavy’s next scheduled launch, currently NET June 22.
A challenger approaches…
Although Mr. Steven’s prospects look better than they have in months, SpaceX’s fairing recovery engineers and technicians have not been sitting on their hands. Begun as a check against the growing possibility that reliably catching fairings in a (relatively) small net is just too difficult to be worth it, SpaceX has been analyzing methods of reusing fairings without Mr. Steven. Most notably, despite the failure to catch fairings out of the air, the fairing halves themselves – relying on GPS-guided parafoils – have proven to be capable of reliably performing gentle landings on the ocean surface.
This consistently leaves the fairings intact and floating on the ocean but at the cost of partial saltwater immersion and exposure to surface-level sea spray and waves. At least in today’s era of highly complex large satellites, customers typically demand that payload fairings (like Falcon 9’s) offer a clean room-quality environment once the satellite is encapsulated inside. Sea water is full of salt, organic molecules, and water, all three of which do not get along well with extremely sensitive electronics. The whole purpose of recovering and reusing fairings is to make their reuse more efficient and less expensive than simply building a new fairing. The task of cleaning composite structures to clean room-standards after salt water exposure and immersion tends to be less than friendly to both aspirations.
According to SpaceX CEO Elon Musk, however, that challenge may be distinctly solvable and could even be easier than the Mr. Steven approach. After Falcon Heavy’s commercial Arabsat 6A launch debut in April 2019, Musk again confirmed that SpaceX would be ready to test that alternate method of fairing reuse very soon and plans to do so on an “internal” (i.e. Starlink) launch later this year. As noted below, this is helped by the fact that SpaceX’s internally-developed Starlink satellites apparently have no need for the acoustic insulation panels that normally protect sensitive spacecraft from the brutal acoustic environment produced by rockets while still in Earth’s atmosphere.
For fairing reusability, the lack of those panels is just one less thing to have to worry about cleaning or replacing. Intriguingly, it’s easy to imagine that – much like SpaceX has apparently designed Starlink satellites to be resistant to intense acoustic environments – the company could have also required that they be tough enough to tolerate a less-than-pristine fairing environment. With that approach, SpaceX could continue to build new fairings for every customer launch, entirely amortizing their production cost before transferring the ‘dirty’, flight-proven fairings to internal Starlink launches.
In essence, SpaceX’s customers would quite literally be paying the company to build the very Falcon 9 boosters and fairings it will ultimately use to launch its massive Starlink constellation, requiring hundreds of launches over the next decade. The faster and more efficiently SpaceX can build and launch Starlink, the faster it can develop Starship/Super Heavy and entirely transcend any concerns of salty fairings (let alone expendable upper stages). But in the meantime, Mr. Steven will return to his catching duties and SpaceX will continue to attempt to reuse payload fairings.

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.

It looks a lot like a rocket — we all remember the shape in Austin 🤣 https://t.co/cFOPEuiJ4u

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.
