SpaceX team spotted removing Block 5 landing legs prior to teardown analysis
Teslarati photographer Tom Cross has captured SpaceX technicians removing the landing legs from the first Falcon 9 Block 5 booster, signaling that the end of recovery operations are near.
Of note, it appears that SpaceX chose to conduct this recovery much like previous ones by removing the rocket’s legs instead of retracting them, a feature of the Block 5 upgrade prominently noted by CEO Elon Musk and other company officials. A brief time-lapse shows workers carefully removing the legs in a well-worn ballet of heavy machinery, skirting around the massive rocket with expertise developed over the better part of two years of sea and land recoveries of Falcon 9 and Falcon Heavy boosters.
There are a number of possible reasons for SpaceX choosing to remove B1046’s landing legs the ‘old-fashioned’ way, most relating to the fact that this particular booster is a critical pathfinder for the entire future of Falcon 9 Block 5. Musk described this attitude in a lengthy and detailed prelaunch briefing:
We are going to be very rigorous in taking this rocket apart and confirming our design assumptions to be confident that it is indeed able to be reused without being taken apart. Ironically, we need to take it apart to confirm that it does not need to be taken apart.
Both COO Shotwell and Musk have briefly discussed the new functionality of the upgraded legs in the past few weeks, indicating that they are capable of being rapidly and repeatedly stowed without being removed from the rocket, whereas all past booster reuse has required the slow removable and equally slow reattachment of landing legs, assuming Block 3 and 4 boosters even reuse their same landing legs. At a minimum, Musk’s above comment already makes it clear that SpaceX has no plans to reuse this booster immediately, instead conducting an extremely thorough teardown analysis to verify that wear and tear from high-speed atmospheric reentry is within an acceptable range.

Equally plausible, choosing to remove B1046’s landing legs instead of testing the new retraction mechanisms may better preserve the leg hardware in its post-landing state, providing engineers and technicians cleaner and more representative data. One final obvious possibility is that the process of flight-testing new Block 5 leg hardware caused damage or led to some off-nominal telemetry and other visible faults, thus preventing them from retracting.
Because the next Block 5 booster (B1047) is likely nearing its own debut after a thorough round of testing in Texas, captured by an aerial photographer, SpaceX may be pushing hard to complete its post-landing analysis of B1046 as quickly as possible to make way for the imminent launches of several new boosters. If the company hopes to maintain its impressive 2018 flight rate of one launch every two weeks throughout the rest of the year, they will need to refly Block 5 boosters at least 10 times – the last flight-proven commercial Block 4 launch (CRS-15) is currently scheduled for early July, leaving roughly half of all 2018’s upcoming launches manifested on Block 5 Falcon 9/Heavy rockets. Falcon Heavy’s second launch has in fact been pushed back by several months per The Planetary Society, indicating that the construction of the first Block 5 center booster has taken a back seat to the more pressing concerns of Falcon 9 Block 5 boosters, upper stages, and fairings needed to avoid additional customer launch delays.

Regardless, the first successful and nearly-complete recovery of a Falcon 9 Block 5 booster marks a huge milestone for SpaceX. So long as the imminent teardown analysis does not reveal anything especially unexpected, the rocket company is quickly closing in on true rapid reuse with Octagrabber/Roomba’s steady routinization of robotic rocket saving, yet another intact fairing half recovery, and the good condition of B1046 after a relatively hot reentry and landing.

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.
