SpaceX recovers fairing intact for the first time, Starlink communicating back to Earth

Published

on

With the launch of PAZ and two of their own Starlink demo satellites, SpaceX has completed its fourth successful launch of 2018, and continued an aggressive series of reusability-focused flight-tests.

Amazingly, the company managed to successfully recover a fairing intact for the first time ever, an absolutely crucial step towards ramping the Falcon family’s launch cadence and reusability. According to CEO Elon Musk, SpaceX’s fairing recovery vessel Mr. Steven missed the fairing by a few hundred meters, meaning that the fairing gently landed in the Pacific Ocean, rather than Mr. Steven’s now-famous fairing recovery net. This is quite possibly the first time in aerospace history that an orbital rocket’s payload fairing has been recovered intact, and the fairing in question looks very much intact.

As mentioned by Musk, that massive piece of hardware had to survive reentry into Earth’s atmosphere at no less than Mach 8, considerably more than two times faster than the famous SR-71 Blackbird spy plane. While the fairing’s parafoil appears to have sunk after being quickly detached, careful observers will note three vertical bars at its three corners, almost certainly the points where that parafoil attaches to them and allows it to gently float down to the ocean surface.  While not nearly as consequential as SpaceX’s growing expertise with Falcon booster recovery and reuse, each fairing – made largely of carbon fiber composites – takes a huge amount of time and effort to complete, and cost upwards of $3 million each ($6m for both halves). In this sense, SpaceX has managed to recover a pallet of cash, as Musk humorously likened the effort fairing reuse to in 2017.

Given just how good the fairing’s condition appears to be, as well as the calm sea states, it’s very likely that SpaceX will try to pick up the landed fairing with a crane, although that would require a different vessel – Mr. Steven has no crane! Teslarati’s Pauline Acalin will undoubtedly be checking out the Port of San Pedro once Mr. Steven has returned to shore, in hopes of capturing the first-ever photos of a recovered orbital rocket fairing.

Starlink hopes tempered despite apparent success

While only mentioned a few times during the webcast, the Falcon 9 that launched earlier today was also carrying additional co-passengers – two SpaceX demonstration satellites, in this case. Confirmed to have successfully deployed and begun communicating with SpaceX ground control, this is another huge accomplishment for SpaceX and marks their first-ever steps into dedicated satellite manufacturing and operation. Despite the significance of this event, SpaceX was keen to lower expectations for the satellite internet network, named Starlink. The following statement was provided during the webcast:

“Even if these satellites work as planned, we still have considerable technical work ahead of us to design and deploy a low Earth orbit satellite constellation. If successful, [this system] would provide people in low to moderate population densities around the world with affordable, high-speed internet access, including many that have never had internet access before.”

For all intents and purposes, this appears to be a significant departure from previous statements given about Starlink by the rocket company. The explicit mention of “low and moderate” population densities being the only focus of service contrasts heavily with a general sense that Starlink was intended from the outset to provide universal internet around the globe to anyone who could afford the service. This certainly serves as a confirmation that there are major technological hurdles that will need to be overcome for Starlink to become the universal internet many have come to hope for from SpaceX – it would appear that it will be quite difficult to serve high-density populations with SpaceX’s current choice of technologies for their constellation.

Still, the demand is undeniably there. Even readers of Teslarati expressed an immediate desire to ditch their cable companies and ISPs, both in the US and abroad. If SpaceX can make it happen, they will have hordes of eager ISP-hating internet users desperate for any alternatives, and your author is proudly among them. The badly served aside, it sounds like SpaceX may be pivoting towards Starlink as a method of connecting the underserved – mainly those in rural or undeveloped areas. Even in the US, this is a major problem for those that do not live near large cities, and US ISPs are exceptionally anti-consumer in these situations – often times charging obscene costs for cable installation or outright refusing to provide coverage. Starlink could be a boon for those individuals in the US and elsewhere, especially where a simple lack of infrastructure is the cause. Much of Africa suffers from this, although mobile networks have become a backbone for a relatively unique pattern of mobile phone usage.

Here’s to hoping that SpaceX manages to once again rise to an exceptional technological challenge. As with all R&D efforts, the company’s satellite effort would be helped immensely with additional funds, and thankfully Falcon 9 Block 5 is very nearly ready to fly its first missions. This highly reusable iteration of the rocket could enable SpaceX to fly dozens of missions with a single Falcon 9 booster, and would thus enable unprecedented profit margins for a launch company, at least in the interim. Eventually, SpaceX is bound to bring down its prices for the customer, but the first need to recoup their reusability and Falcon Heavy investments, while also ensuring a sound business plan to support the development of their BFR and BFS vehicles that may one day enable the colonization of space. Starlink may be another beneficiary of those profits, and could itself one day act as a source of reliable funding for SpaceX’s interplanetary endeavors.

Tesla has a Cybercab problem nobody saw coming

Tesla’s Cybercab line now builds robotaxis faster than Tesla can deploy them, Lars Moravy says.

Tesla’s Cybercab line in Texas can now build the two seat robotaxi faster than the company can put it into service, according to Lars Moravy, Tesla’s Vice President of Vehicle Engineering. “We don’t run every day because the line can run so fast. It’s currently outpacing our deployments,” Moravy said in a new Cybercab deep dive from Munro Live. “So, it’s a bit of a race right now. Who’s going to go faster? Right now the manufacturing line’s ahead.”

Tesla’s official Robotaxi account shared a Cybercab analysis video on X on Monday, calling it a “Cybercab engineering deep dive.” Moravy’s comments go further than what he told analysts on the Q3 earnings call last week, when he said the Cybercab line’s listed capacity of more than 125,000 units a year undersells what it can actually run.

The tour shows where that speed comes from. Tesla’s unboxed process splits the Cybercab into front, rear, side and center modules that are built and tested on their own before they meet on a short final line. That final line has just 25 fully automated stations, which Tesla’s team estimated is a fifth to a tenth of what a Model Y needs. The full line is about 78% automated, the framing line is already at 100%, and the layout uses roughly 50% less floor space per vehicle. The stated goal is “100% automation in 10 second cycle time,” or one finished Cybercab every 10 seconds.

Tesla also deleted the paint shop. Only the side modules are coated, and the exterior panels get their color inside the molding machine. Engineers said the car is designed to run at least 500,000 miles, which matters for a vehicle that will spend most of its day carrying riders.

The battery got the same treatment. The Cybercab uses an 88S6P pack of 4680 cells in a steel enclosure, a first for Tesla, with each module potted separately so a single failed module can be swapped instead of the whole pack. Wireless battery management boards replace a wiring harness, and new contactors are fast enough to drop the pyro fuse entirely. Tesla’s battery director graded the pack an A minus, compared with a D for the Model Y structural pack and a B minus for Cybertruck. Up front, the drive unit runs an 11:1 gear ratio versus roughly 9:1 on most Teslas, since the Cybercab does not need a high top speed.

The deployment side is now the bottleneck Moravy described. Tesla had more than 50 Cybercabs working the Formula 1 weekend in Austin, and Texas records show 463 Cybercabs registered. Tesla said on its earnings call that Cybercab service will launch in Dallas next month, and Moravy said the company is aiming to get Cybercabs to customers by the end of 2026. Every unit built so far has gone into Tesla’s own fleet since the line moved into volume production in April.

Munro Live also asked when it could get a Cybercab to tear down. Tesla’s answer: “Not yet.”

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.
