SpaceX stacks orbital Starship sections as Elon Musk teases June 20th event
SpaceX CEO Elon Musk says he will provide a public update on the development status of Starship and Super Heavy in an official presentation later this summer, possibly as soon as June 20th.
Meanwhile, SpaceX’s South Texas team have been busy at work on both Starhopper and a newer Starship, said by Musk to be the first orbit-capable prototype. In the last week, technicians have begun stacking several sections of the vehicle’s stainless steel hull, all fabricated and welded together side-by-side. On Thursday, May 9th, this progressed to the installation of the Starship’s first gently tapered nose section atop its cylindrical tank section. Likely the second- or third-to-last major stack before its aeroshell is assembled into one piece, the orbital prototype is starting to truly resemble a real Starship.
They grow up so fast…
CEO Elon Musk revealed SpaceX’s Mars colonization architecture back in September 2016 and has since provided design and development updates every 6-12 months. Between then now, Starship/Super Heavy (formerly BFR, fore-formerly ITS) has radically changed. Originally baselined with a diameter of 12 m (40 ft), an almost entirely carbon composite design, and a spaceship with bulky tripod fins/wings, SpaceX helped design, build, and test a full-scale liquid oxygen tank.
Six months after the tank was destroyed (likely intentionally) during testing, Musk announced in Sept. 2017 that ITS was now called BFR and would feature a leaner 9m (30 ft) diameter. He also revealed tentative plans to enlist BFR in a point-to-point Earth transportation scheme offering travelers access to almost anywhere on Earth in ~30 minutes. In September 2018, the design changed once more, gaining ~10m of height and three mobile tripod fins/wings/legs. Finally, just a few months after the 2018 update, Musk revealed that SpaceX was moving almost entirely away from carbon composites and would instead use stainless steel throughout BFR’s structure. BFR was also renamed to Starship/Super Heavy.
Episode 4: Revenge of the Steel
Given SpaceX’s breakneck pace of Starhopper and Starship development, it’s possible that Musk’s “probably June 20th” event is meant to correlate with a yet-unknown Starship or Starhopper milestone. Back in early January, Musk suggested that the first orbital Starship prototype could be “complete” as early as June. However, a few weeks later, Starhopper suffered a setback when its facade/nosecone toppled over and was irreparably destroyed.
Several months distant, it’s hard to actually say if that hardware loss has impacted SpaceX’s schedule much at all. Sans nose section, SpaceX instead conducted a number of wet dress rehearsals and successfully ignited Raptor and jumped the tethered Starhopper a few feet in early April, more or less right on schedule per a December 2018 Musk tweet.
At this point in time, it’s highly unlikely that the orbital Starship prototype will be truly complete just a month or two from now. Most notably, “completion” would require seven flight-ready Raptor engines, of which SpaceX is known to have only completed 3-4 in the last four months. Despite an apparent lack of Raptors for a June completion of the orbital prototype, it may actually be possible for SpaceX to complete (in a very rough sense) the main structure of the Starship.
Major progress has been made in the last few weeks and the orbital prototype is starting to look more and more like an actual Starship. Aside from finishing the vehicle’s propellant and header tanks and engine section/thrust structure, SpaceX still needs to install avionics, wiring, plumbing, cold-gas maneuvering thrusters, COPVs, access and umbilical ports and panels, an entire heat shield, its tripod wings/fins/legs, and more. At the same time, it’s unclear if SpaceX will attempt to send Starship to orbit on its own before the first Super Heavy booster prototype is complete, an even more massive undertaking ahead of the company.
For now, all we can do is wait and watch SpaceX’s gloriously bizarre steel Starship prototype continue to grow, while Starhoppper prepares for untethered hops a few thousand feet to the east. Things could be worse!

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.
