Despite a number of technical hurdles, SpaceX CEO Elon Musk believes that the company’s next-generation Starship spacecraft could eventually be capable of pad aborts in the event of a Super Heavy booster failure before liftoff.

For a vehicle as large and heavy as Starship, this would necessitate a number of compromises, but would undoubtedly serve as a major confidence-booster for prospective passengers in lieu of an established record of reliability. If Starship were capable of pad aborts like the company’s Crew Dragon spacecraft, high-profile and high-value customers like NASA and other space agencies could be far more willing to place astronauts and payloads on what they perceive to be a bizarre but high-performance launch vehicle.

Although SpaceX would almost certainly prefer that Starship and Super Heavy skip the first half of Falcon 9’s life cycle (marked by two catastrophic failures), building a new launch vehicle – particularly one with all new materials, engines, and production processes – is extremely challenging, and failures are to be expected as kinks are worked out.

On the plus side, after several lessons were learned the hard way, SpaceX has demonstrated that it can build an extremely reliable launch vehicle. Since its last catastrophic failure in September 2016, SpaceX has successfully completed 49 launches of Falcon 9 and Falcon Heavy in barely 2.5 years, compared to 29 launches (with 2 failures) from 2010 to 2016. In short, SpaceX has simultaneously proven that it can beat almost any other single provider’s launch cadence and do so with impressive reliability, all while pushing the boundaries of reusable rocketry and constantly upgrading flight hardware.

Destroying customer payloads remains unacceptable, but the ultimate success of SpaceX’s Falcon launch vehicle family – at the cost of two operational failures – is undeniable. With Starship and Super Heavy, SpaceX thankfully has several new advantages, owing to its spectacular success over the last few years. With the fruit of major fundraising in hand, an independent F9/FH launch business humming along, and the freedom to pursue significant R&D projects on its own dime, SpaceX may be able to stomach one or several Starship/Super Heavy failures and do so during internal missions.

By accepting possible (and probable) vehicle failures during development and insulating SpaceX’s external customers from any associated risk, the company should be able to develop Starship and Super Heavy in exactly the ways it wants to.

Hence CEO Elon Musk’s indication that SpaceX “is not planning for pad abort with early Starships”. In short, adding the ability for pad aborts to Starship would/will be a major challenge. Assuming a dry mass of 100 tons (220,000 lb) and a wet mass of 1000-1200 tons (2.2M-2.7M lb), Starship’s six planned Raptor engines – capable of producing up to ~1200 tons of thrust at sea level – could be barely enough to lift a fully-fueled spacecraft. In pad abort scenarios, the rocket booster would be suffering some sort of catastrophic failure, if it wasn’t already mid-explosion. As such, getting far away from said explosion as fast as possible is the name of the game, particularly if the priority is ensuring passenger/astronaut survival.

Starting a high-performance liquid rocket engine fast enough to make an abort possible is also a major challenge, though Musk says that Raptor could be capable of extremely fast start-ups in emergency scenarios. Assuming that Raptor can somehow be ignited from standstill in less than a second (preferably 0.1-0.5s) and would still be able to ignite a second time for a soft landing, SpaceX could technically give Starship the thrust-to-weight ratio needed to quickly escape a Super Heavy failure by reducing the propellant load. With the minimal propellant needed to safely reach a stable low Earth orbit (LEO) during crewed Starship launches, SpaceX would have to lean almost exclusively on rapid orbital refueling, but the combination might be enough to ensure that Starships can abort at almost any point during launch.

It’s extremely unlikely that SpaceX will pursue this capability during the prototype phase, but it may not be out of the question for the first crewed mission(s) of finalized Starships.

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.
