SpaceX wraps up a decade of reusable rocketry with fastest booster recovery yet
SpaceX has completed its 13th and final launch and landing of the year and decade, marked by a Falcon 9 booster’s successful return to Port Canaveral and subsequent processing to prepare it for another orbital-class mission.
Over the course of that recovery, SpaceX broke the record for the fastest Falcon 9 processing by several hours, a small but significant step towards the company’s ultimate goal of launching and landing the same Falcon 9 booster in less than 24 hours. Additionally, SpaceX appears to have finished processing booster B1056 on December 21st, the 4th anniversary of Falcon 9’s first successful landing after an orbital-class launch.
Since that first success on December 21st, 2015, SpaceX has rapidly moved through several distinct iterations of Falcon hardware, constantly improving components, systems, and the overall fit, finish, and reliability of the rocket. Over the last four years, SpaceX has landed an incredible 47 Falcon 9 and Falcon Heavy boosters as part of 60 orbital-class launches, while the company recently launched Falcon 9 B1048 for the fourth time and flew the same two Falcon Heavy boosters in April and June. Ultimately, 2019 has been a spectacularly successful year for SpaceX, and – by the numbers – 2020 is set to be several times more ambitious, still.
On December 20th, less than a day after arriving in Port Canaveral, SpaceX technicians began the process of retracting Falcon 9 booster B1056’s four deployed landing legs. As it turns out, B1056 – returning to port for the second time after its third launch – became the first Falcon 9 booster to have all of its landing legs successfully (and semi-permanently) retracted in May 2019. To accomplish the feat, SpaceX designed a custom retraction mechanism that simultaneously serves as the crane jig used to lift the booster while vertical.
“The crux of the need for a relatively complex crane-and-jig method of leg retraction rests on SpaceX’s landing leg design. Put simply, after rapidly deploying with a combination of gravity and hydraulics, Falcon 9 landing legs have no built-in way to return to their stowed state. Each of the four legs are quite large, weighing around 600 kg (1300 lb) and stretching about 10m (33 ft) from hinge to tip. They use an intricate telescoping carbon fiber deployment mechanism to give them legs enough strength to stand up to the stresses of Falcon 9 booster landings.
Combined, the legs’ size and telescoping mechanism makes the addition of an onboard retraction mechanism impractical. All the needed hardware would struggle to find a good place for installation and would quite literally be dead weight during launches and landings, stealing from Falcon 9/Heavy payload capacity and generally serving no purpose until a booster has been lifted off the ground with a giant crane.”

Impressively, SpaceX took less than an hour and a half to successfully retract all four of thrice-flown Falcon 9 B1056’s also thrice-flown landing legs. Less than three hours after the rocket’s legs were snugly retracted, SpaceX immediately attached a second crane and brought the booster horizontal. Altogether, this made Falcon 9 B1056’s third recovery the fastest SpaceX has ever performed by 3-6 hours – seemingly small progress but still no mean feat.
SpaceX’s fastest-ever Falcon 9 recovery – from the drone ship berthing to the booster departing the port on a transporter – occurred with B1049 after its third launch and landing, taking just 2.01 days (48.25 hours). Falcon 9 B1056’s third recovery appears to have beaten that record by at least several hours, brought horizontal and installed on a SpaceX transporter perhaps less than 1.75 days (42 hours) after arriving in port – more than 10% faster than B1049’s previous record.
Meanwhile, SpaceX lifted a fairing half recovered off the surface of the Atlantic Ocean by GO Ms. Tree, appearing unharmed after having potentially been dropped when the ship’s secondary (fairing) fishing net tore while moving the Falcon 9 hardware.
With any luck, that fairing half will be in good enough shape to be reused on a future Starlink mission, seemingly unlikely but proven to be well within the realm of possibility after SpaceX’s very first fairing reuse involved two halves recovered off the ocean surface after Falcon Heavy Block 5’s April 2019 debut. B1056, however, is all but guaranteed to fly again – this time on its fourth launch – in the near future. SpaceX has dozens of launches planned in 2020, so there will be plenty of opportunities.

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.
@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.
