SpaceX has completed its 13th and final launch and landing of the year and decade, marked by a Falcon 9 booster’s successful return to Port Canaveral and subsequent processing to prepare it for another orbital-class mission.

Over the course of that recovery, SpaceX broke the record for the fastest Falcon 9 processing by several hours, a small but significant step towards the company’s ultimate goal of launching and landing the same Falcon 9 booster in less than 24 hours. Additionally, SpaceX appears to have finished processing booster B1056 on December 21st, the 4th anniversary of Falcon 9’s first successful landing after an orbital-class launch.

Since that first success on December 21st, 2015, SpaceX has rapidly moved through several distinct iterations of Falcon hardware, constantly improving components, systems, and the overall fit, finish, and reliability of the rocket. Over the last four years, SpaceX has landed an incredible 47 Falcon 9 and Falcon Heavy boosters as part of 60 orbital-class launches, while the company recently launched Falcon 9 B1048 for the fourth time and flew the same two Falcon Heavy boosters in April and June. Ultimately, 2019 has been a spectacularly successful year for SpaceX, and – by the numbers – 2020 is set to be several times more ambitious, still.

On December 20th, less than a day after arriving in Port Canaveral, SpaceX technicians began the process of retracting Falcon 9 booster B1056’s four deployed landing legs. As it turns out, B1056 – returning to port for the second time after its third launch – became the first Falcon 9 booster to have all of its landing legs successfully (and semi-permanently) retracted in May 2019. To accomplish the feat, SpaceX designed a custom retraction mechanism that simultaneously serves as the crane jig used to lift the booster while vertical.

The crux of the need for a relatively complex crane-and-jig method of leg retraction rests on SpaceX’s landing leg design. Put simply, after rapidly deploying with a combination of gravity and hydraulics, Falcon 9 landing legs have no built-in way to return to their stowed state. Each of the four legs are quite large, weighing around 600 kg (1300 lb) and stretching about 10m (33 ft) from hinge to tip. They use an intricate telescoping carbon fiber deployment mechanism to give them legs enough strength to stand up to the stresses of Falcon 9 booster landings.

Combined, the legs’ size and telescoping mechanism makes the addition of an onboard retraction mechanism impractical. All the needed hardware would struggle to find a good place for installation and would quite literally be dead weight during launches and landings, stealing from Falcon 9/Heavy payload capacity and generally serving no purpose until a booster has been lifted off the ground with a giant crane.”


Teslarati — May 7th, 2019

Impressively, SpaceX took less than an hour and a half to successfully retract all four of thrice-flown Falcon 9 B1056’s also thrice-flown landing legs. Less than three hours after the rocket’s legs were snugly retracted, SpaceX immediately attached a second crane and brought the booster horizontal. Altogether, this made Falcon 9 B1056’s third recovery the fastest SpaceX has ever performed by 3-6 hours – seemingly small progress but still no mean feat.

SpaceX’s fastest-ever Falcon 9 recovery – from the drone ship berthing to the booster departing the port on a transporter – occurred with B1049 after its third launch and landing, taking just 2.01 days (48.25 hours). Falcon 9 B1056’s third recovery appears to have beaten that record by at least several hours, brought horizontal and installed on a SpaceX transporter perhaps less than 1.75 days (42 hours) after arriving in port – more than 10% faster than B1049’s previous record.

Meanwhile, SpaceX lifted a fairing half recovered off the surface of the Atlantic Ocean by GO Ms. Tree, appearing unharmed after having potentially been dropped when the ship’s secondary (fairing) fishing net tore while moving the Falcon 9 hardware.

With any luck, that fairing half will be in good enough shape to be reused on a future Starlink mission, seemingly unlikely but proven to be well within the realm of possibility after SpaceX’s very first fairing reuse involved two halves recovered off the ocean surface after Falcon Heavy Block 5’s April 2019 debut. B1056, however, is all but guaranteed to fly again – this time on its fourth launch – in the near future. SpaceX has dozens of launches planned in 2020, so there will be plenty of opportunities.

Elon Musk

Tesla Phone? Not quite, but close: analyst

For years, there have been images and videos across social media platforms that have reminded me of when I was a 15-year-old kid teased by “Xbox 720” videos on YouTube. These videos are of the supposed “Tesla Phone” that Elon Musk was secretly developing in between leading Tesla with its electric cars and SpaceX with its reusable rockets.

Although Musk has put those rumors to bed several times, it was never completely out of the realm that he could get involved in cell phones in some capacity. Think outside the box and more macro-level, though. Instead of reinventing the computer, Musk reinvented connectivity by developing Starlink with SpaceX.

It could be something similar, TD Cowen analyst Gregory Williams said in a note last week, where he hinted SpaceX could be gathering some steam to acquire T-Mobile.

Williams said it would be the “clear choice” for SpaceX if it decided to go through with a network acquisition. He also suggested AT&T.

The move would be possible through selling more of its own stock, which would help SpaceX raise the money to purchase T-Mobile, which would cost roughly $300 billion. It could be one of the moves SpaceX makes post-IPO in terms of an acquisition: it already acquired Cursor AI for $60 billion.

Other analysts, like Dan Ives of Wedbush, believe SpaceX and Tesla will eventually merge into one anyway, and that conglomeration could come as soon as this year, some have said.

The implications of SpaceX purchasing T-Mobile are massive. A combined entity would create a truly ubiquitous network: T-Mobile’s terrestrial 5G towers and Starlink’s growing constellation of Direct-to-Cell satellites. This would essentially eliminate dead zones across the U.S. and potentially globally.

SpaceX would instantly become a full-scale facilities-based carrier with satellite differentiation; a huge advantage. This would pressure AT&T and Verizon heavily.

There are also concerns like a potential reduction in long-term competition, and of course, a deal of that size would face intense scrutiny from government agencies.

The strategic fit is compelling due to the existing Starlink–T-Mobile partnership and complementary technologies (space + terrestrial). It could create a dominant integrated communications player. However, the regulatory, financial, and execution hurdles are enormous — this remains highly speculative with no indication SpaceX is actively pursuing it right now.

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.
