SpaceX techs work towards Falcon 9 fairing recovery with wacky series of experiments
Over the course of the past week, Teslarati photographer Pauline Acalin has captured a multitude of unusual occurrences at SpaceX’s Port of Los Angeles dock space, each time involving a Falcon fairing recovery vessel like Mr Steven or NRC Quest, a Falcon fairing half (flight-proven or otherwise), and one of several attenuating circumstances.
More likely than not, what appears as a menagerie of weird and disconnected events on the sidelines is actually a reasonably organized leg of a larger program, in this case focused on experimentation and testing to close the fairing recovery loop and secure Mr Steven’s first successful fairing catch.

The mystery of Catalina Island
Now-iconic fairing recovery vessel (or net-boat, or claw-boat) Mr Steven has been out of commission since late August, at which point SpaceX technicians removed all four of his arms and their eight complementary shock absorber booms towards unknown ends. If SpaceX’s past is any judge, those arms are probably in the process of being upgraded, but it’s impossible to judge thanks to the fact that they have simply disappeared from the Berth 240 docks where they were briefly stored. SpaceX certainly has a way with transporting massive, ungainly objects without stirring a whisper.
Despite lacking arms for more than a month, Mr Steven has still performed a number of sea-trials, ranging from average jaunts a few miles away to a mysterious armless test described in the tweet above. Why exactly Mr Steven was involved in an experiment involving a helicopter “picking an item” – in this case a flight-proven Falcon fairing – off of a vessel while entirely lacking the arms and net he would use to catch said fairing is entirely unclear. Perhaps it was meant to test a datalink or a change to fairing recovery hardware. Whatever transpired, a group of SpaceX technicians certainly flew to Catalina Island and were working alongside or with a Blackhawk helicopter capable of externally carrying up to 3600 kg (8000 lb) of cargo.

- Mr Steven was out and about conducting high-speed maneuvers two days prior, and also joined NRC Quest near Catalina Island on the 20th. (Pauline Acalin)
- NRC Quest returned to port with a Falcon fairing aboard after a long day doing *something* at sea. (Pauline Acalin)
- Note the sooty tip of the fairing’s nose, a telltale sign that it previously flew on a Falcon 9 launch. (Pauline Acalin)
Multipurpose recovery vessel NRC Quest – nominally dedicated to Cargo Dragon spacecraft recoveries – returned to SpaceX-leased Berth 240 a few hours after the September 20th test window closed, sooty Falcon 9 fairing half in tow. Still, this certainly isn’t the weirdest Falcon fairing-related activity to occur last week.
Fairings aplenty
Meanwhile, over at Mr Steven’s old berth and drone ship Just Read The Instructions’ current berth, a different Falcon fairing half appeared sometime in the last several days in an unusual state, seemingly either fresh out of the factory or in an advanced state of disassembly. The base of this particular fairing half seems to be entirely missing the usual layer(s) of material (cork, among other things) used to waterproof and act as a lightweight heatshield. A new fairing half sitting out in the elements with zero protection would be exceptionally unusual, as CEO Elon Musk has noted that they each cost several million dollars ($3m to be precise), and exposure outside of a cleanroom could very well prevent this half from ever being operationally flown.

The next best conclusion to be drawn is that this unique fairing half is new or flight-proven (with skin and shielding removed), but sitting at SpaceX’s dock space in order to prepare for one or several active drop tests in pursuit of Mr Steven’s first successful fairing catch. But who really knows, to be honest. The fairing’s bare carbon fiber composite construction is certainly a sight to behold, one way or another.
Doing…something.
This leads us to the grand (perhaps… titanic) finale of wholly unexpected Falcon fairing activities over the last several days. Presumably making the best of an opportunity to test NRC Quest’s ability to recover Falcon fairings after splashdown (i.e. missing Mr Steven’s net), the pictures generally tell the story better than any words ever could. Keep your eyes peeled for Fairing Wrangler job openings.

- This extraordinarily unusual operation lent an opportunity to see just how flexible and structurally optimized SpaceX’s payload fairings are. (Pauline Acalin)
- After returning from a day at sea doing who-knows-what, Mr Steven’s captain attempted to use the 500 metric ton vessel to splash a fellow recovery tech. A for effort. (Pauline Acalin)
Up next for SpaceX, Mr Steven, and the West Coast recovery crew is SAOCOM-1A, scheduled to launch from California’s Vandenberg Air Force Base on the evening (Pacific Time) of October 6th.

Tesla Full Self-Driving gets first-ever European approval
Tesla owners in the Netherlands with a Full Self-Driving subscription will receive a software update “shortly,” the company said, activating the operation of the company’s semi-autonomous driving tech for the first time in Europe.
Tesla Full Self-Driving (Supervised) got its first-ever European approval, as the Netherlands gave the suite the green light to begin operation.
Tesla owners in the Netherlands with a Full Self-Driving subscription will receive a software update “shortly,” the company said, activating the operation of the company’s semi-autonomous driving tech for the first time in Europe.
The Dutch vehicle authority RDW granted the type approval after more than 18 months of rigorous testing on both closed tracks and public roads. FSD Supervised complies with UN R-171 standards and benefits from Article 39 exemptions under EU Regulation 2018/858. Importantly, it is not a fully autonomous vehicle.
The RDW stressed that the driver remains fully responsible and must maintain attention at all times. “Safety is paramount for the RDW,” the authority stated. “Proper use of this driver assistance system contributes positively to road safety.” Sensors monitor driver alertness, issuing warnings if eyes leave the road or hands are unavailable to take control immediately.
CEO Elon Musk also commented on the approval in a post on X, saying:
“First (supervised) FSD approval in Europe! Congratulations to the Tesla team and thank you to the regulatory authorities in the Netherlands for all of the hard work required to make this happen.”

Trained on billions of kilometers of real-world driving data, FSD Supervised allows the vehicle to handle residential streets, dense city traffic, and highways under constant supervision. Tesla’s post declared:
“It can drive you almost anywhere under your supervision – from residential roads to city streets & highways. No other vehicle can do this.”
The company added that it is “excited to bring FSD Supervised to more European countries soon.”
This national approval paves the way for broader EU adoption. Other member states can recognize the Dutch certification individually, with a potential bloc-wide rollout via European Commission committee vote anticipated by this Summer. The decision underscores Europe’s stricter safety and documentation requirements compared to U.S. self-certification.
Tesla Europe shares FSD test video weeks ahead of launch target
The Netherlands’ approval represents a pivotal step for Tesla in Europe, where complex regulations and mixed traffic have delayed rollout. Musk added that the RDW was “rigorous” in its assessment of FSD.
By proving the system’s safety in one of the continent’s most bicycle- and tram-heavy nations, Tesla positions itself to transform mobility across the EU—delivering greater convenience while keeping drivers firmly in control.
As the first domino falls, anticipation builds for FSD Supervised to reach additional countries soon.

Tesla is using a redesigned Cybertruck battery cell to mitigate Semi challenges
It is perhaps the most recent example of Tesla using unique engineering prowess and cross-pollinating vehicle elements to solve common problems, something it does better than most companies out there.
Tesla revealed that it is utilizing redesigned Cybertruck battery cells in its Long Range Semi to mitigate some pertinent challenges that come with long-haul logistics.
It is perhaps the most recent example of Tesla using unique engineering prowess and cross-pollinating vehicle elements to solve common problems, something it does better than most companies out there.
Tesla’s long-awaited Semi truck is entering production at its Nevada Gigafactory, and fresh factory footage reveals a clever evolution in its battery technology.
The Long Range variant, designed for up to 500 miles of real-world range, relies on a structural battery pack that uses the same 4680-form-factor cells found in the Cybertruck.
However, Tesla engineers have completely redesigned the pack’s architecture—shifting from the flat, pancake-style modules typical in passenger vehicles to a compact, vertical cubic layout. This change isn’t just about cramming more energy into the chassis; it’s a targeted solution to one of electric trucking’s biggest headaches: range loss in cold climates.
Dan Priestley, Head of the Tesla Semi program, said:
“We’re using essentially the same cell out of Cybertruck, but our cars packs are more like a pancake. Whereas these are more like a cube. You get a lot of energy stored in a small space. You can only do this if you design the vehicle to be electric from the ground up.”
Here, in all its glory, is the exclusive first look at the massive @Tesla Semi factory.
Our @corememory crew went to Nevada to see the line come to life, as it gets ready to pump out thousands of all-electric trucks. We saw the new cab and went on a drive too. Wunderbar! pic.twitter.com/a0S5zVEr87

In conventional EVs, battery packs are laid out horizontally in wide, flat arrays to fit under the floor. While this works for cars and even the Cybertruck’s structural pack, it exposes a large surface area to the elements.
Heat escapes quickly, especially overnight when the truck is parked. Cold temperatures slow chemical reactions inside lithium-ion cells, reducing available energy and forcing the vehicle to expend extra power warming the battery and cabin.
Real-world tests on vehicles like the Cybertruck show winter range losses of 20-40 percent, depending on conditions. For long-haul truck drivers operating in Canada, Scandinavia, or the northern U.S., this “silent killer” means unplanned stops, reduced payloads, and higher operating costs.
From personal experience, cold weather still impacts EV batteries even with various inventions and strategies that companies have come up with. In the cold Pennsylvania winter, charging was much more frequent for me due to range loss due to temperatures.
Tesla’s cubic battery pack flips the script. By arranging the 4680 cells in tall, dense vertical stacks, the pack minimizes external surface area relative to its volume—essentially turning the battery into its own thermal blanket.
Factory video from the Semi assembly line shows these large, yellow-green structural modules mounted directly onto the chassis, forming a near-cube shape.
The reduced exposure helps the pack retain heat generated during operation, keeping cells closer to their optimal temperature even after hours in sub-zero conditions.
The design doesn’t stop there. Tesla pairs the cubic pack with an advanced heat pump system that actively recycles thermal energy from the motors, brakes, and even ambient air.
Tesla reveals various improvements to the Semi in new piece with Jay Leno
Unlike passive systems in earlier EVs, this architecture transfers waste heat back into the battery, maintaining readiness for morning departures without draining the pack.
Executives have noted that the combination, cubic geometry plus intelligent thermal management, dramatically cuts overnight cooldown and range degradation, making the Semi viable for 24/7 fleet operations in harsh winters.
Beyond cold-weather performance, the redesigned pack integrates structurally with the truck’s frame, enhancing rigidity while simplifying assembly. Production footage shows workers installing the massive modules early in the line, signaling that the Semi’s battery is now a core chassis component rather than an add-on.
Using proven 4680 cells keeps costs down and leverages Tesla’s scaled manufacturing know-how from Cybertruck and Model Y lines.
Tesla’s focus on ramping up Semi output will lean on small innovative steps like this one. Truckers are not immune to traveling in cold weather conditions, and changes like this one will help make them more effective while also increasing output by logistics operators who choose to go all-electric with the Tesla Semi.

SpaceX is keeping the Space Station alive again this weekend
SpaceX’s Falcon 9 launches Northrop Grumman’s Cygnus NG-24 to the ISS with 11,000 pounds of cargo Saturday.
SpaceX is targeting April 11 for the launch of Northrop Grumman’s Cygnus XL cargo spacecraft to the International Space Station, carrying over 11,000 pounds of supplies, science hardware, and equipment for the Expedition 73 crew aboard. Liftoff is set for 7:41 a.m. ET from Space Launch Complex 40 at Cape Canaveral Space Force Station, with a backup window available April 12 at 7:18 a.m. ET.
The mission, officially designated NG-24 under NASA’s Commercial Resupply Services program, names its spacecraft the S.S. Steven R. Nagel in honor of the NASA astronaut who flew four Space Shuttle missions and logged over 723 hours in space before his death in 2014. Unlike SpaceX’s own Dragon capsule, which docks autonomously, Cygnus relies on NASA astronauts to capture it using a robotic arm before it is berthed to the space station’s module for unloading. When the mission wraps up around October, the Cygnus will depart loaded with station trash and burn up on reentry.
Countdown: America is going back to the Moon and SpaceX holds the key to what comes after
This is the second flight of the Cygnus XL configuration, which debuted on NG-23 in September 2025 and offers a roughly 20% increase in cargo capacity over the previous design. Northrop Grumman switched to Falcon 9 launches after its own Antares 230+ rocket was retired in 2023 following supply chain disruptions from the war in Ukraine.
The upcoming cargo includes a new module to advance quantum research, and an investigation studying blood stem cell production in microgravity with potential therapeutic applications on Earth.
The NG-24 mission is one piece of a much larger picture for SpaceX and the U.S. government. As Teslarati reported, SpaceX has become an indispensable launch provider for U.S. national security missions, picking up a $178.5 million Space Force contract in April 2026 to launch missile tracking satellites, while also holding roughly $4 billion in NASA contracts tied to the Artemis lunar program.
At a time when no other American rocket can match the Falcon 9’s combination of reliability, cost, and launch cadence, Saturday’s mission is a straightforward reminder of how much the U.S. government now depends on a single commercial provider to keep its astronauts supplied and its satellites flying.
