SpaceX reveals Falcon fairing recovery progress as Mr. Steven barely misses catch

SpaceX has offered an extraordinary glimpse into a stealthy program of Falcon fairing recovery research and development, which has utilized drop tests and iterative hardware and software upgrades to inch ever closer to fairing reuse over the last 6-9 months.

Short of a small handful of sparse comments made by executives in 2018, this is the first time SpaceX has officially acknowledged its continued attempts to optimize Falcon fairing recovery in the face of a number of missed post-launch catches. Given that the pictured fairing was so close to a successful landing that its parafoil actually became caught in Mr. Steven’s net, it seems that SpaceX has nearly solved the problems that have thus far prevented program success.

In the last six months of 2018, SpaceX has continued to tease its slow progress towards reusable Falcon fairings, originally planned to depend on a truly bizarre solution – Mr. Steven. An impressive vessel on its own, SpaceX has gradually added and extended and upgraded a range of recovery hardware on his deck, most notably including a vast net (likely tens of thousands of square feet or 2000+ square meters) supported by four huge arms and eight supporting booms. Despite increasing the usable area of the net, SpaceX has been unable to secure an operational fairing catch since it began attempts in March 2018.

In late May 2018, SpaceX provided the best look yet at the actual process of recovering Falcon fairings, showing off the guided parafoil (a wing-like parachute) and revealing that a fairing half – launched in support of Iridium-6/GRACE-FO – had splashed down just 50 meters (~165 ft) away from Mr. Steven’s net.

However, in the months that followed, info about catch attempts became increasingly sparse and it eventually became clear that SpaceX was preparing to perform a range of controlled drop tests a few hundred miles off the coast of California. Ultimately, the company’s engineers and technicians hoped to use the controlled environment and a greater number of available drop/catch attempts to refine the hardware and software needed to finesse fairing halves into Mr. Steven’s net.

It may be almost absurdly large relative to any other conceivable thing that exists in the real world, but a few thousand square meters is actually more like a needle in a haystack for a piece of rocket traversing a 500-800 km arc at top speeds of more than 2 km/s.

 

In December 2018, following another sadly unsuccessful fairing recovery attempt on the West Coast, SpaceX CEO Elon Musk revealed that engineers were also apparently looking into backup plans in case closing that last 50-meter gap turned out to be more expensive or complicated than it was worth. Most notably, he implied that SpaceX was interested in finding ways to waterproof and ultimately refly Falcon fairings even after soft-landings in seawater, whereas fairings are already capable of reliably landing intact in the ocean but cannot be reused due to seawater contamination and cracking caused by impact.

Given just how close Mr. Steven appears to be to a successful in-net fairing recovery, it now seems implausible that SpaceX will choose just one of the two options at hand, likely instead progressing both development programs to points of success. Once fairings can both be successfully waterproofed and caught in Mr. Steven’s net, SpaceX will almost certainly have itself a foolproof solution to easy and reliable recovery and reuse even in bad sea states and stormy weather.

With the company’s first launch of 2019 probably just a few days away, chances seem good that SpaceX will attempt at least one more post-launch fairing recovery with Mr. Steven. Fingers crossed!

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.

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 Full Self-Driving v14 ‘Lite’ Release Notes: new capabilities and features

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.

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.
