SpaceX’s Pacific rocket recovery fleet heads to sea for Western Block 5 debut
SpaceX drone ship Just Read The Instructions was spotted by Teslarati photographer Pauline Acalin departing Port of Los Angeles on the evening of July 22, while fairing catcher Mr Steven completed final checkouts and full installation of his massive new net, hopefully just days away from the first successful fairing catch. Their call to action, Iridium NEXT-7, is scheduled to launch NET 04:39 PDT/11:39 UTC, July 25th.
Over the course of July, both vessels have been undergoing significant maintenance and upgrades. Mr Steven’s was perhaps the most extreme – his original arm and net apparatus was removed in its entirety and replaced with a massively upgraded system of arms, booms, and a brand new net, well and truly expanding the vessel’s catching area by a factor of four.
With a new net and arm span stretching at least 60 meters by 60 meters, Mr Steven’s improved fairing catching mechanism is now almost the same size as the landing area aboard SpaceX’s two autonomous spaceport drone ships – roughly 200ft x 300ft (60m x 90m). While presumably a pure coincidence, the size parallels apparently necessary to recover two very different components of Falcon 9 – the booster rocket and the payload fairings – is rather satisfying.
A last hurrah?
Intriguingly, ASDS Just Read The Instructions has stoically remained at SpaceX’s Port of San Pedro, CA berth for more than nine months, wholly unused despite the fact that the company has completed four additional missions since its last tasked booster recovery (October 2017, Iridium-3). It’s not a coincidence that all four of those Vandenberg AFB missions featured boosters that had already successfully launched and landed once before – SpaceX made a habit over the last four months of intentionally expending Falcon 9 boosters after their second missions, even when the launch conditions would allow for booster recovery.
This mission will thankfully bring an end to that understandable but still-painful practice, thanks to Iridium-7’s new Block 5 booster, B1048. Many of the months JRTI spent at berth were without the pod thrusters the drone ship needs to keep itself at the proper landing point once at sea, but JRTI departed the port with a full complement of four blue thrusters on the evening of July 22. However, it’s unclear how much SpaceX will need the vessel within just a month or two from today.

At long last, SpaceX’s planned, built, and now-patiently-waiting West Coast landing zone is finally finished, permitted, and in the green to begin supporting Falcon 9 return-to-launch-site (RTLS) recoveries at Vandenberg Air Force Base. Effectively a basic copy of SpaceX’s now well-worn landing zone pair in Cape Canaveral, Florida, the company’s VAFB LZ-1 has been hinted at in two FCC launch permits for launches as early as the first and last weeks of September. Aside from Iridium launches, of which just one will remain after Iridium-7, nearly all of SpaceX’s West Coast launches are for fairly lightweight payloads that should easily allow Falcon 9 RTLS recoveries.

Environmental conditions mean that JRTI will still be needed regularly for a handful of months (March through June) to avoid disrupting baby seals (pups, technically), but the vessel’s recovery efforts this week may be one of the last ‘off-season’ examples for months or even years to come. On the plus side, RTLS recovery at SpaceX’s VAFB landing zone will be an absolute dream for recovery technicians, as the LZ is directly beside the launch pad and hangar, where recovered Block 5 boosters can likely be refurbished or at least easily packaged and shipped to the Hawthorne factory.

A Tesla Semi caught fire in Hayward, California, which caused both directions of traffic to shut down for hours before being completely reopened early on Wednesday, the California Highway Patrol said.
The fire occurred just after 5:30 local time in Hayward on Tuesday, as the Semi caught fire in the southbound lanes of I-880 before CHP officials made the decision to shut down both lanes of traffic due to potential risks from hazardous chemical smoke.
There were no injuries reported.
🚨 A Tesla Semi reportedly caught fire, with California Highway Patrol confirming. The Semi was on I-880 SB
An estimated 5,000 to 7,000 semi-truck and large commercial vehicle fires occur on U.S. roadways every year

The cause of the fire is currently unknown, as neither Tesla nor the CHP have not determined a cause.
However, some images taken before the Semi was completely destroyed by the fire seem to indicate this might have been an older unit, as it appears to be one of the designs that Tesla shipped as part of its pilot program, before revising it and starting mass production just a month ago.
@Tslachan From on of the videos looks like it’s an old Semi (not the refresh version that recently started production) https://t.co/KzwmR2kXow

At the time of publication, CHP had not returned our request for a comment for additional details, including the Semi involved and any potential collaboration on an investigation between the CHP and Tesla. We will update this story when we hear back from them.
The southbound lanes were reopened at 3:30 a.m. on Wednesday, with the northbound lanes opening last night a few hours after the fire began. The CHP did state that the lithium batteries were “incredibly difficult to extinguish,” according to NBC Bay Area.
The truck’s driver said that the Semi caught fire, but he did not have an explanation.

Tesla’s launch of the “Emergency Drive Away” function a few months back offered owners a safe option to evacuate an area if they were in reasonable danger. The function finally got its first use in the real world, but it appears it was by mistake.
A video shared by u/Joshalander in the r/TeslaLounge subreddit recorded the instance from his vehicle and said the incident took place in Austin this past weekend during the city’s F1 Race.
“Was charging around 6 AM this past Sunday in Austin before heading to the F1 race and heard a pop. Looked over and saw the new emergency drive-away feature in action. Genuinely felt bad for the dude when he got out and realized what happened, since he looked exhausted and only seemed to half-read the prompts.”
🚨 Here’s the first look at Tesla’s Emergency Drive Away function in action:
Apparently this driver accidentally enabled it and drove forward; you can see the Supercharger pull with the car.
Tesla said previously this would cost up to $25k if not used properly. https://t.co/B4qQRrsO6B

Emergency Drive Away unlatches the Supercharger connector from the vehicle, but still causes damage to both the car and the Supercharger. Tesla has said that it will cost up to $25,000 in repairs to have everything fixed back to normal.
Additionally, the company said that if it were not used in an emergency situation, the driver of the vehicle who activated the Emergency Drive Away feature would be responsible for all repair costs.
Tesla constitutes the following situations as reasonable justifications for activating the feature:
- You face an immediate threat to your life or personal safety.
- You must leave the area immediately.
- Exiting the vehicle is unsafe.
- Unplugging the charge connector would unreasonably delay your departure or expose you to a risk to your personal safety.
After using the feature, Tesla requires the driver to schedule Service so the car can be inspected.

Tesla’s Cybercab battery design could make robotaxis even cheaper
Tesla built the Cybercab’s battery pack with spare room for a future switch to LFP.
Tesla built the Cybercab’s battery pack with empty space inside it on purpose, and the reason points to a cheaper robotaxi down the road.
Robert Sumpf, Tesla’s director of mechanical design engineering for battery modules and packs, said the extra room beside and beneath the Cybercab’s modules was left there so the company can move to lithium iron phosphate cells later. “So, we protected this pack to go to an even lower energy dense chemistry as we scale and need to bring LFP into the platform,” Sumpf said in a Cybercab deep dive with Munro Live.
The Cybercab runs on Tesla’s own 4680 cells with a nickel chemistry today. LFP cells store less energy for their size, so a straight swap would cut range. The reserved space lets Tesla add more LFP cells to make up the difference. In return, Tesla would get cells that cost less, run cooler and survive more charge cycles. LFP became the most used EV battery chemistry in the world last year.
Not all of that room was planned for a chemistry change. Lars Moravy, Tesla’s Vice President of Vehicle Engineering, said part of it exists because “we didn’t need as many batteries as we thought we did.” Tesla told Sandy Munro in early 2025 that it was targeting a Cybercab pack under 50 kWh with close to 300 miles of range.
The pack also breaks from the structural design Tesla used in some Model Y and Cybertruck builds. Instead of potting hundreds of cells into one block, the Cybercab uses four separate, individually sealed modules, so a bad module can be replaced without scrapping the whole pack. Sumpf was blunt about the older approach, giving the Model Y structural battery “a grade D” because it was hard to build and nearly impossible to repair. He estimated a fully structural pack gains about 10% more cell volume, but said “the issue is the service cost.”
That cost matters more for a car that rarely sits parked. Cybercab chief engineer Eric Earley said replacing an entire pack “before half a million miles is a killer on cost,” which is why remanufacturing and serviceability were built into the design from the start.
The same Munro Live tour produced Moravy’s admission that the Cybercab line at Giga Texas is now outpacing Robotaxi deployments, along with a look at the robotaxi’s unorthodox paint process. Tesla is aiming to deliver the first Cybercabs to outside customers by the end of 2026, though Elon Musk has said the vast majority will stay owned by Tesla and run as a transport service.
Sumpf did not give a date for an LFP version, name a cell supplier or say how a chemistry change would affect range. For now, the 4680 cars keep piling up: Texas DMV records from Tuesday list 544 Cybercabs authorized for Tesla’s Robotaxi fleet, more than the 507 Model Ys on the same roster for the first time.
