SpaceX Starship rocket set to reach full height for the second time ever

A SpaceX Starship prototype is on track to become the first to reach its full, operational height in a permanent fashion, following in the footsteps of a much earlier prototype that had its nose section temporarily installed last year.

Known as Starship Mk1, that prototype served as more of a learning experience, pathfinder, and mockup over the ~8 months it took to build it and the few weeks it took to destroy it. While its conical nose section was partially outfitted with smaller ‘header’ propellant tanks, it was never fully installed, with SpaceX only temporarily stacking it on top of Starship Mk1’s tank section to serve as the centerpiece of CEO Elon Musk’s October 2019 update event. Mk1’s nosecone was removed shortly after the event was over, while the rocket’s more important tank section was rolled to a nearby launch pad for testing.

More than six months later, Starship SN5 appears to be firmly on its way to becoming the first of SpaceX’s next-generation launch vehicle prototypes to have a (mostly) functional nose section permanently installed. If that ends up being the case, SpaceX’s fifth full-scale Starship prototype may become the first to have multiple Raptor engines installed and the first to perform a high-altitude flight test. Of course, that will depend quite heavily on the fate of Starship SN4, currently trapped in limbo after a May 19th static fire caused SpaceX to partially lose control of the rocket.

While not immediately clear, comments made by CEO Elon Musk and SpaceX officials suggested that the company was aiming to perform low-altitude hops with Starship SN4 and graduate to high-altitude testing with the next prototype off the assembly line (SN5). With a development program as agile as SpaceX’s Starship effort, however, plans are liable to change at almost any moment.

On May 17th, however, it became clear that – at least for the time being – SpaceX fully intends for Starship SN5 to become the first serially-produced ship to have a nosecone installed. On that Sunday, a brand new steel nose section – the fourth built by SpaceX in the last few months – was rolled out of a massive factory tent, revealing labels that rather unambiguously read “SN5”.

SN5 refers to Starship serial number 5, the fifth full-scale rocket prototype overall and fourth built since the start of 2020. Over the last six or so months, SpaceX has dramatically expanded its production footprint in South Texas, reaching a point now where it’s churning out a rough Starship prototype every month, on average. Starship SN5 is no different, with its tank section largely completed as of May 15th, give or take a day or two.

Now, on May 19th, a new collection of five stacked steel rings appeared alongside Starship SN5’s largely completed tank and engine section. Combined with the new nosecone labeled “SN5”, it’s now readily and unequivocally apparent that the prototype is probably a matter of days away from having a nosecone installed. Unless SpaceX has adopted different methods for Starship SN6 production and assembly, a stack of five steel rings – lacking any sign of a tank dome welded inside it – will serve as the base that SN5’s nosecone can be stacked on top of. Once stacked with its nose section, Starship SN5 will measure some 50m (~165 ft) tall – at least several meters taller than a Falcon 9 booster.

The nosecone itself is also quite interesting, featuring two sets of four mysterious thruster nozzles, signs of interior components and reinforcements, and two recessed struts presumably meant to attach to Starship’s forward flaps.

While exciting, there is certainly still a chance that Starship SN4 – trapped at the launch pad – will have to be destroyed or will be unsalvageable even if SpaceX is able to finally access and safe the prototype. If so, Starship SN5 will likely take its place, performing a Raptor static fire, a ~150m (~500 ft) hop test, and an additional ~3 km (~1.9 mi) flight test before potentially moving on to triple Raptor operations and high-altitude flights. Stay tuned for updates on SN4’s fate and SN5’s production status.

Tesla reveals huge Cybercab detail in new guide for First Responders

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.”

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.
