SpaceX’s drone ships near return-to-action with Block 5 Falcon 9 landings
Teslarati photographer Pauline Acalin’s recent trips to drone ship Just Read The Instructions’ berth in Port of San Pedro shows that SpaceX technicians are nearly done preparing the hibernating vessel for a return to Falcon 9 rocket recoveries in the Pacific Ocean, a ten-month drought likely to end for good on July 20th.
Although it’s hard to believe, SpaceX’s West Coast autonomous spaceport drone ship (ASDS) has been effectively marooned at its Port of Los Angeles berth for more than nine full months, with the vessel’s last recovery occurring just after the October 9 launch of ten Iridium NEXT satellites, the fourth of five SpaceX Vandenberg launches in 2017 (and the fourth of four West Coast booster landings).

Three months after that October mission and booster recovery, SpaceX expended their next California launch and marked the beginning of a streak of eight missions where flight-proven Block 3 and 4 boosters could have been recovered but no attempts were made. While intermixed with the spectacle of Falcon Heavy’s dual side booster landings at LZ-1, the debut launch and recovery of Falcon 9 Block 5, and two other Block 4 booster recoveries, the majority of SpaceX’s launches since December 2017 have been treated as expendable – put simply, the company decided that recovering and refurbishing twice-flown boosters of older Falcon 9 blocks was not worth the effort and expense.
Instead, those well-worn boosters were expended in the Pacific and Atlantic Oceans after partially supporting a series of experimental tests designed to gather additional data on the recovery envelope of SpaceX’s partially reusable rockets. The rationale makes sense – SpaceX fundamentally sacrificed some of its older, less-reusable Falcon 9 boosters for the sake of knowledge that may allow their highly reusable Falcon 9 Block 5 predecessors a better chance of successfully landing even after exceptionally fast, hot, and high-energy recoveries, a necessity if the upgraded rockets are to be reused 10 to 100 times, as is the goal.
Although Just Read The Instructions spent several months without a full complement of maneuvering thrusters, thanks in part to efforts to keep its besieged East coast sister Of Course I Still Love You operational, photographer Pauline Acalin’s photos over the last several months show that the vessel now has four full thrusters installed and ready to bring it back into rocket recovery action in the Pacific Ocean.

Still, the abrupt return to expendable rocket launches after a year – 2017 – filled to the brim with 18 of 18 successful launches and 14 of 14 successful landings led to a decidedly fascinating vein of disapproval in the SpaceX enthusiast and broader spaceflight fan communities – people had grown accustomed to the adrenaline-soaked thrill of routine Falcon 9 rocket landings. Some expressed worries that regularly and intentionally expending large hunks of metal in the ocean could harm their ecosystems and was tantamount to littering. None the wiser, every other launch provider in the world continues to expend all of their rocket boosters without any attempts at recovery like the nearly all non-Shuttle rocket launches in the past six decades, and their tepidly reusable next-generation rockets are unlikely to even begin attempting hardware recovery until the mid-2020s at the earliest.
Frankly, SpaceX’s abrupt successes with orbital-class rocket recovery struck a chord with observers, demonstrating just how intuitive attempting to recover expensive rocket hardware really is, while also bringing into clear focus the actual insanity of failing to try and of the seemingly ad-hoc rationalization of expendable rocketry. Thankfully, we still have SpaceX, and the company’s spate of rocket booster sacrifices is likely just one expendable launch away from coming to an effective end for the indefinite future, with that particular launch – CRS-15 – scheduled less than two weeks from now, on June 29th.

After CRS-15, which will probably see its twice-flown Block 4 booster expended in the Atlantic, a combination of Block 5 Falcon 9s and Heavies will theoretically bring to an end the practice of expending orbital rocket boosters, at least on SpaceX’s watch. Considering that the upgraded boosters have been designed and built to launch as many as ten times with minimal refurbishment and potentially 100+ times with regular maintenance, the opportunity cost of an expended Block 5 rocket booster is so high that it is difficult to imagine SpaceX will be easily swayed to expend one until it’s flown at least several times prior.
We here at Teslarati eagerly await the imminent demise of expendable rockets, set to begin in earnest – at least for SpaceX – around July 19th and 20th with two Falcon 9 Block 5 launches on two coasts, one with Telstar 19V (Florida) and the other with Iridium-7 (California).

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.
An estimated 5,000 to 7,000 semi-truck and large commercial vehicle fires occur on U.S. roadways every year.
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.
