Completed on May 30th, SpaceX’s latest Falcon 9 booster recovery smashed several internal speed records, unofficially cataloged over the years by watchful fans.

In short, as the company’s experienced recovery technicians continue to gain experience and grow familiar with Falcon 9 Block 5, the length of booster recoveries have consistently decreased in the 12 months since Block 5’s launch debut. Already, the efficiency of recovery processing has gotten to the point that – once SpaceX optimizes Block 5’s design for refurbishment-free reuse – there should be no logistical reason the company can’t fly the same booster twice in ~24-48 hours.

The road to rapid reusability

Rarely will it make headlines, but the fact remains that SpaceX’s ultimate goal is not just to reuse Falcon 9 (and other) boosters, but to do so with a level of routine efficiency approaching that of modern passenger aircraft. It’s reasonable to assume that chemical rockets might never reach those capabilities, but they may certainly be able to improve enough to radically change the relationship between humans and spaceflight.

Along that line of thinking, SpaceX CEO Elon Musk decided years ago that an excellent representative goal for Falcon 9 would be to launch the same booster twice in 24 hours. In the last year or so, that largely arbitrary target has changed a bit and is now believed to be a bit wider, aiming for booster reuse within a few days of recovery. This is a pragmatic adjustment more than a technical criticism of Falcon 9.

In general, Falcon 9 simply doesn’t have the performance necessary for routine reusability timelines measured in hours. The majority of SpaceX launches need enough of Falcon 9’s performance to necessitate recovery aboard one of SpaceX’s two drone ships, typically stationed at least a 200-300 km (100-200 mi) offshore. That fact alone almost single-handedly kills any chance of sub-24-hour booster reuse, given that the process of towing the booster-carrying drone ship back to port happens at a max speed of ~10 mph (15 km/h). Just gaining permission to enter the port itself often involves waits of 6+ hours a few miles offshore.

Low orbit, low mass Falcon 9 missions are much more promising for extremely rapid reusability, given that both of SpaceX’s West and East coast landing zones are located just a few miles (or less than 1500 feet, in the case of LZ-4) from their corresponding launch pads and processing facilities. However, these missions are quite rare, while SpaceX’s own low Earth orbit (LEO) Starlink launches will likely involve payloads so heavy that long-distance drone ship recoveries will be necessary.

Finally, there are Falcon Heavy launches, most of which will allow for both side boosters to return to the Florida coast for landings at LZ-1/LZ-2. However, these pose their own barriers to rapid reuse, mainly due to the fact that side boosters – while technically just Falcon 9 boosters – would need major changes to support a single-stack Falcon 9 launch. Falcon Heavy launches simply aren’t going to happen back-to-back over a period of 24-48 hours, so that option is also out of the question.

This means that SpaceX’s only real option for practical rapid reuse is to instead focus on something closer to a weekly launch capability for Block 5 boosters, meaning that the same booster would be able to launch, land, return to shore, and prepare for the next launch in the same week. Even then, launch site readiness may still stand in the way of truly radical improvements in booster reuse and launch frequency. After each launch, SpaceX’s pads and transporter/erectors take a significant beating, requiring routine repairs and maintenance before returning to flight-readiness. Barring major improvements, SpaceX has demonstrated minimum launch-to-launch times of roughly 10 days, and cutting that figure by 50-90% will be a major challenge for a rocket as powerful as Falcon 9.

B1049 takes a step forward

Despite the many logistical reasons that Falcon 9 will likely never lend itself to routine ~24-hour reusability, having that latent capability would still mean that the hardware is advanced enough to offer that efficiency. Even if SpaceX can’t literally fly each booster at its operational capacity, nearly refurbishment-free reflights will still translate into dramatically lower launch costs. Modern civilian aircraft need not fly every second of every day to still be affordable to operate (excluding amortization costs).

Ultimately, SpaceX has been taking small steps in that direction ever since the company began recovering (and reusing) Falcon 9 boosters. Falcon 9 B1049’s third recovery has been one of the best (and most record-breaking) steps yet, but those records were only just broken The most significant statistic to come out of the post-Starlink v0.9 recovery is that B1049.3 took less than 30 hours to go from docking in port to being horizontal on a SpaceX booster transporter. The previous record-holder was Falcon 9 B1046.2, requiring approximately 40 hours for the same feat. B1049.3 also holds the record for fastest recovery overall – just 48 hours from docking to being transported to a SpaceX hangar – but only beat B1051 by about half an hour. In general, Falcon 9 Block 5 has been privy to consistently quick recovery operations and B1049 is just the latest in a long line of reusable SpaceX rockets.

Tesla Semi catches fire in California: what we know

Published

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.

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.

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 ‘Emergency Drive Away’ function gets its first use in the real world

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.”

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.

Published

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.
