Despite the spectacular demise of a full-scale prototype just days ago, a senior SpaceX engineer and executive believes that Starship could still be ready for its first orbital launch attempt before the end of the year.

Even if the first launch attempt fails, that milestone – if realized – would be one of the single biggest upsets in the history of spaceflight, proving that Saturn V-scale orbital-class rockets can likely be built in spartan facilities with common materials for pennies on the dollar. Much like Falcon 1 suffered three launch failures before successfully reaching orbit, there’s a strong chance that Starship’s first shot at orbit will fall short, although each full-up launch failure would likely cost substantially more than the current prototypes being routinely tested to destruction in South Texas.

Most recently, what CEO Elon Musk later described as a “a minor test of a quick disconnect” went wrong in a spectacular fashion, causing a major liquid methane leak that subsequently ignited and created a massive explosion. Although Starship SN4 did technically complete its fifth Raptor engine static fire test just a minute or so prior, the ship and its immediate surroundings were obliterated by the violent explosion, leaving little more than steel shrapnel and the broken husk of a launch mount behind. It’s in this context that one of SpaceX’s most levelheaded, expert executives believes that an orbital launch could still happen this year.

While Starship SN4’s demise and the continued possibility of the ship’s orbital launch debut occurring less than seven months from now may seem at odds with each other, that’s actually just a side effect of the approach SpaceX has always taken when developing brand new rockets and spacecraft. Following the lead of the scrappy teams that used the exact same methods to design, test, and fly the massive Saturn rockets that took humans to the Moon, SpaceX has always preferred to learn by doing.

Inevitably, testing minimum viable products to their limits will lead to failures, but those failures are actually extremely valuable so long as they are extensively analyzed and learned from. That’s exactly what SpaceX has been doing for the last six or so months with full-scale Starship prototypes: building, testing, failing, and improving in an unending cycle. Built slowly with inferior methods, Starship Mk1 almost immediately during its first pressure test in November 2019. SpaceX took that failure, extracted all the insight it could, and dramatically improved its production methods before completing Starship SN1 barely three months later.

Starship SN4 marked the most recent failure during SpaceX’s hardware-rich development program.

Prior to SN1, SpaceX built and tested two stout test tanks to failure, ultimately achieving pressures of ~8.5 bar – sufficient for reliable human spaceflight – with the second tank on January 30th, 2020. On February 28th, Starship SN1 was unfortunately destroyed by a faulty ‘thrust puck’ (Raptor engine mount). Just 10 days later, SpaceX successfully tested a third ad-hoc test tank, proving that it had already rectified the engine section design flaw. Hardware isn’t always the only problem, however, and Starship SN3 was destroyed by human operator error during a cryogenic proof test on April 3rd.

Starship SN4 was completed and moved to the launch pad less than a month later and began testing just a few days after that, quickly racking up milestones as it became the first full-scale prototype to pass cryogenic proof testing, perform a wet dress rehearsal (WDR) with real propellant, fire up a Raptor engine, and complete a more ambitious cryogenic pressure test. Prior to the ground systems fuel leak that killed it, SN4 was possibly just days away from attempting the inaugural flight of a full-scale Starship prototype.

With Starship SN4 now steel confetti, Starship SN5 – effectively complete – will likely take over where its predecessor left off, heading to the launch pad within the next week or so before attempting a cryogenic pressure test and Raptor static fire to clear it for flight. Per Koenigsmann, that flight debut could come just a few weeks from now – likely before the end of June if replacement ground equipment can be quickly completed. If Starship SN5 survives that hop debut, it may ultimately be upgraded with a nosecone, flaps, and two additional Raptor engines to perform a dramatic 20 km (~12 mi) flight, capped with a supersonic skydiver-style reentry and landing test.

Once that capability has been successfully demonstrated, Super Heavy development and orbital Starship operation and reentry are the next critical hurdles. If Koenigsmann is correct, it’s safe to say that the first fully heat-shielded Starships and the beginnings of the first one or several Super Heavy booster prototypes will begin to appear in South Texas within the next few months.

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.
