SpaceX’s Starship to grow in height as workers prepare to stack its top section
SpaceX CEO Elon Musk has teased new details and posted several new photos of Starship Mk1, taken on September 25th as employees worked to lift the spacecraft’s lower half onto a mobile transporter. Up next: stacking the rocket’s two halves to reach its final 50m (160 ft) height.
The company is currently working around the clock to complete Starship Mk1’s assembly and integration ahead of Elon Musk’s planned September 28th presentation, meant to provide a detailed update on the state of the next-generation rocket’s design and development. A huge amount of work clearly remains but SpaceX is making major, visible progress almost every single day along the path to Starship’s first flight tests.

Taken yesterday afternoon, Musk’s photos show scenes before and after technicians placed Starship Mk1’s lower half – its tank and propulsion section – on a ‘Roll-Lift’, a small transporter. It’s unclear why exactly this was done, but SpaceX moved the spacecraft prototype about 100m and then removed it from the transporter.
The most recent movement happened just a few hours ago – technicians used a crane delivered on September 24th to lift the half-Starship onto what looked like half a dozen steel blocks on the ground, all captured live on LabPadre’s 24/7 livestream. In order to install Starship Mk1’s separate landing legs, believed to attach somewhere inside the vehicle’s aft circumference, SpaceX likely needed to lift the aft section off the concrete mount that had been its home for the past several months.
Elon Musk also confirmed that Starship Mk1 will have six landing legs, another strong indicator that the ongoing Thursday morning work is focused on preparing Starship Mk1 for leg installation. According to Musk, Starship Mk1 will weigh as much as 200 metric tons (440,000 lb) empty, which is probably why the rocket prototype’s aft – and heaviest – half had to be loaded onto a Roll-Lift and could not simply be moved by the crane itself.
Starship’s updated design remains a bit of a mystery just two days before Elon Musk is scheduled to present an update, likely including new renders from SpaceX itself. It remains to be seen if Starship’s six landing legs will be fixed (versus retractable) or if the legs on the windward side of the ship will jut out into the airstream. To ensure stability when landing on unprepared terrain, as Musk described, six legs are certainly better than three, but the actual span of those legs is a more relevant determinant of stability. Wide, Falcon 9-style legs would be optimal, indicating that the final ship will likely lean towards legs that can be retracted or at least angled behind Starship’s reentry ‘shadow’.
Still a prototype (and possibly meant solely for suborbital operation), Starship Mk1 (and Mk2) may feature simplified legs and mechanisms to speed things along, serving as more of a rough draft while Starhopper was akin to a Starship abstract or prospectus. At this rate, we won’t have to wait very long at all to find out.

Tesla revealed a major new Cybercab detail in a guide it released for First Responders, showing new territory in its beliefs and intentions for the ride-hailing-focused vehicle that entered production in April.
The First Responders Guide is released to give fire departments, paramedics, and other emergency personnel the proper guidance on what to do in the event of an accident, entrapment, or other situation that would require immediate attention.
On one of the pages of the First Responders Guide, Tesla revealed a stark detail about the Cybercab, which could help personnel enter the vehicle more easily in case of an emergency.
Tesla Cybercab has one important piece that AI4 cars might need for FSD
It shows Tesla has no intention of releasing any Cybercab units that were initially proposed for ride-hailing services for the general public with any manual controls, meaning a steering wheel or pedals:
“A Cybercab equipped with steering wheel, brake pedal, and an acceleration pedal is typically an engineering or test vehicle, and operates at SAE Level 2 autonomy. Cybercab is not typically equipped with a steering wheel or acceleration and brake pedals.”

This is a major development for those who continue to believe Tesla planned to release the Cybercab with any sort of manual controls so that passengers could take over if needed. However, when Tesla started manufacturing production versions of the Cybercab in Giga Texas earlier this year, they were spotted without a steering wheel or pedals.
It essentially confirms the company has no intentions of bringing manual controls to the car’s production versions. Some have argued that the likelihood of Tesla having something
There still are some Cybercab units out there with a steering wheel and pedals, and as Tesla said, these cars are engineering or test vehicles, which have Safety Monitors on board to help the car out of a precarious situation or emergency.
Tesla released the Full Self-Driving v14 ‘Lite’ suite to owners of Hardware 3 or AI3 vehicles today, adding several new features to the vehicles that were once believed to be capable of unsupervised self-driving.
Now, Tesla has released this modified suite to older Tesla vehicles, adding plenty of new features and capabilities.
Here are the full release notes for the suite:
- Distilled the intelligence from HW4 V14 into HW3. This allows HW3 to directly learn how to handle scenarios using HW4 V14 as a guide. This process unlocks the improvements that have been made to HW4 including Reinforcement Learning (RL) and offline models for HW3.
- Improved both proactive and reactive responsiveness across a wide variety of categories including navigation handling, merges and forks, pedestrian interactions, traffic lights, and vehicle cut-in scenarios.
- Improved general comfort in nominal scenarios through fewer false slowdowns, smoother steering and more consistent lane centering.
- Introduced parking, unparking, and reversing capabilities.
- Added Arrival Options for you to select where FSD should park: in a Parking Lot, on the Street, in a Driveway, or at the Curbside.
- Speed Profiles are now available at all times, to further customize driving style preference.
These improvements, according to Tesla’s Head of AI, Ashok Elluswamy, help distill the driving behavior from AI4’s v14 series into both the camera and compute configurations of AI3.
Tesla Full Self-Driving v14 ‘Lite’ for older cars finally gets released
He added:
“It includes destination options and speed profiles on city roads, but more importantly significantly improved safety. We hope you’ll enjoy it, once the build ships wide.”
FSD v14 Lite is now rolling out to AI3 early-access customers. Based on the feedback, will rollout to more customers over the next few weeks.

Tesla will continue to roll out the v14 Lite suite more widely in the coming weeks, the company said.
Tesla has finally released its Full Self-Driving v14 ‘Lite’ suite for older cars that equip the Hardware 3 or AI 3 chip, which have not been able to handle the newest versions of the company’s driver assistance software.
Tesla officially started releasing the v14 Lite suite to owners in the Early Access Program last night. The company’s Head of AI, Ashok Elluswamy, said that the rollout will continue over the next few weeks. The build distills the driving behavior from AI4’s v14 series into both the camera and compute configurations of an AI3 car.

It also includes a variety of new features that were available to AI4 cars running v14, including:
- Start Self-Driving from Park
- Arrival and Parking Options
- Speed Profiles
The release is highly anticipated because those owners with AI3 vehicles were early adopters into the FSD platform and were promised that their cars would be capable of achieving Full Self-Driving.
However, Tesla CEO Elon Musk admitted during the company’s recent Q1 Earnings Call that these vehicles would not be capable of achieving unsupervised Full Self-Driving, which is what Tesla had originally said.
Owners were not pleased with this answer, or the idea that their commitment to buying the suite outright for thousands of dollars would not yield the ability to drive without operating the car. Tesla gave some solutions for this, including a discount on a new car, or an upgrade to an AI4 or AI5 self-driving computer and new, upgraded cameras.
Tesla owners do not seem pleased with these options, as they require giving the company more money.
Nevertheless, it is important to note that Tesla came through for owners here by releasing v14 Lite before the end of Q2, something it had promised owners during the previous Earnings Call. Tesla has had trouble keeping up with timelines, but this is a big achievement for the team.
