SpaceX bids goodbye to older Falcon 9s with Florida ‘jellyfish’ launch spectacle
SpaceX’s final Block 4 Falcon 9 has completed its second and last orbital mission with a spectacular sendoff visible for hundreds of miles along the East Coast, harkening back to “alien invasion” comparisons that followed an equally stunning SpaceX launch from California last December.
Although the Falcon 9 booster was expended in the Atlantic Ocean minutes after launch, its upper stage remains in orbit in an experimental test of its lifespan, while the mission’s flight-proven Cargo Dragon spacecraft separated from the rocket and headed to the International Space Station with a promise of a possible third orbital reuse in 2019. This mission’s Dragon capsule flew for the first time in late 2016 for the CRS-9 mission and spent the two years since then having its heat shield and other major components refurbished or replaced, likely at a cost to SpaceX less than half that of constructing a brand-new Dragon spacecraft.

According to Jessica Jensen, SpaceX’s Director of Dragon Mission Management, SpaceX’s Dragon refurbishment team has also gotten considerably more efficient over several years of experience reusing the orbital spacecraft, now up to three reflights of three separate capsules. She noted in the postlaunch conference that – if all major components are healthy upon CRS-15’s early-August return to Earth – this capsule could be refurbished for its third mission in as few as months, which would make it one of the last Dragon 1 launches before the upgraded Dragon 2 begins crewed flights and takes over all cargo missions. After CRS-15, five more of those Cargo Dragon flights remain until CRS-2’s 2020 takeover, all of which will utilize flight-proven capsules.

Falcon 9, on the other hand, reached a truly historic milestone today for SpaceX – B1045’s second and final flight marks the last rocket SpaceX will fly that does not feature a number of upgrades designed to dramatically improve booster reusability. Known as Falcon 9 Block 5, all future SpaceX missions (at least until BFR’s debut sometime in the early 2020s) will be launched aboard the upgraded rocket. If it works as intended, Block 5 should theoretically enable a rapid and affordable level of reusability never before achieved by Falcon 9 or any other rocket, for that matter.

While still more than a little disheartening to see a Falcon 9 booster intentionally expended after launch, the spectacle created by B1045’s final flight was fitting, to say the least. Thankfully, the Block 5 takeover of all future SpaceX Falcon 9 and Falcon Heavy launches is likely to also result in a dramatic reduction in SpaceX’s willingness to expend flight-proven rockets after launch. Whereas Block 3 and 4 Falcon 9s were never designed to affordably and safely fly more than two or three times total, minimizing any opportunity cost from expending twice-flown rockets after launch, Block 5 has been purpose-built to allow individual boosters to fly a bare minimum of 10 times with minimal refurbishment and as many as 100 times with regular maintenance. Unless Block 5’s design fails to achieve that level of reusability, SpaceX is extremely unlikely to expend Block 5 boosters unless they have flown a number of times to extract as much value as possible from them.
Up next on SpaceX’s manifest are two back-to-back Falcon 9 Block 5 launches, Iridium-7 from California on July 20 and Telstar 19V from Florida less than 18 hours later. Both Block 5 boosters will be recovered aboard SpaceX’s fleet of drone ships, Just Read The Instructions (JRTI) to the West and Of Course I Still Love You (OCISLY) to the East.

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.
