SpaceX’s fleet of rocket recovery ships is about to get even bigger

Four months after SpaceX gave up on catching Falcon fairings and stripped and returned a pair of leased ships it had modified for that purpose, the company’s permanent fairing recovery solution has just come into focus.

The April 2021 departure of GO Ms Tree (formerly Mr. Steven) and GO Ms Chief from SpaceX’s East Coast fleet made it unambiguously clear that the company was abandoning fairing catching in favor of simply scooping the several million dollar nose cone halves off of the surface of the ocean. By the time that decision was made, SpaceX had reused fairing halves more than two dozen times on more than 15 Falcon 9 launches – practically none of which had actually been caught by Ms Tree or Ms Chief.

In fact, SpaceX had already begun to reuse ‘scooped’ fairing halves on commercial Falcon 9 launches, including two Transporter rideshare missions with dozens of different customers and SiriusXM’s SXM-7 multimillion-dollar geostationary communications satellite. Perhaps even more importantly, SpaceX was routinely flying splashdown fairing halves three or even four times and flew one particular half twice in just 49 days.

Put simply, thanks to the heroic and somewhat unexpected success of a small subset of SpaceX’s fairing recovery, waterproofing, design improvements, and refurbishment upgrades got so good even fairings that splashed down in the Atlantic Ocean could be rapidly reused and flown multiple (now 5+) times apiece. Onto its third consecutive year of only marginal success and a distinct lack of reliability, that meant that SpaceX’s long-struggling effort to catch Falcon fairings had effectively been made redundant.

While it’s likely that scooped fairing halves would never be certified to fly high-value US military or NASA payloads, SpaceX appears to have matured the technology to the point that it’s good enough for Starlink and many (if not most) of its private-sector launch customers. Along those lines, with Ms Tree and Ms Chief out of the picture by early April, SpaceX had to briefly shoehorn Dragon recovery ships GO Navigator and GO Searcher into scooping roles to continue recovering fairings and eventually decided to lease or rent two far larger ships with built-in deck cranes.

For whatever reason, those leases or rentals only lasted a handful of weeks apiece and the latest ship – Hos Briarwood – departed SpaceX’s fleet in early July. In an extremely rare impromptu hiatus, SpaceX hasn’t launched once since late June, likely explaining why Briarwood – with a 100% fairing recovery success rate over two missions – departed when it did.

Now, first reported by SpaceExplored.com, the first signs of SpaceX’s long-expected permanent fairing recovery solution have appeared at an obscure Louisiana drydock. By all appearances, for the first time in its history, SpaceX has outright purchased two decade-old offshore supply ships formerly known as Ingrid and Ella G. Thankfully, SpaceX wiped clean any hint of ambiguity with the installation of a classic SpaceX “X” and by renaming the ships “Bob” and “Doug” after the pair that became the first NASA astronauts to ride a Falcon 9 rocket and Crew Dragon spacecraft to orbit in May 2020.

Relative to any of SpaceX’s more permanent fleet, including ex-members Tree and Chief, Bob and Doug are massive ships, measuring more than 80m (260 feet) long. They’re also five or six times heavier than the likes of GO Searcher or Ms Tree. Aside from an obvious potential role as fairing ‘scoopers’ thanks to the installation of large deck cranes, Bob and Doug also appear to have had heavy-duty winches installed, implying that they could also double as drone ship towboats.

Potentially, that means that SpaceX could shrink the fleet of ships needed to support each drone ship booster landing from two to one, using Bog and Doug to both tow and service the landing platforms at sea.

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 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.

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.
