SpaceX CEO Elon Musk has posted a unique, uninterrupted view of Falcon 9’s latest landing, completed by booster B1056 on July 25th after successfully launching Cargo Dragon on its 18th mission (CRS-18) to the International Space Station (ISS).

Combining four separate views, the video also happens to feature an extremely rare instance of audio clearly recorded from a microphone on Falcon 9 itself, capturing the roar and violence of engine ignition and putting sound to the booster’s hypersonic dive through Earth’s thickening atmosphere.

The synchronized videos begin somewhere in the middle of booster B1056’s atmospheric reentry, smashing head-on through the rapidly thickening air thanks to its nearly perpendicular orientation relative to the ground. During return-to-launch-site (RTLS) recoveries, Falcon 9 and Heavy boosters essentially launch themselves even higher above the point at which they separate from the rest of the rocket. This maneuver typically leads to an apogee 150+ km (100+ mi) above the Earth’s surface, at which point the booster effectively begins a free-fall all the way back to the landing zone.

The video more or less starts at the point that the heating caused by reentry becomes a concern for the booster’s health, signified by the immediate start of a three-engine reentry burn. With said burn, SpaceX quite literally uses the exhaust plume produced as a sort of brake or shield, protecting Falcon 9’s first stage from the worst of the leading-edge heating that would otherwise risk damage to its octaweb and Merlin engines.

Most recently, the potential issues that heating can cause were exemplified by Falcon Heavy center core B1057’s failed June 2019 landing attempt, likely caused by damage suffered by the Merlin 1D landing engine during SpaceX’s fastest booster reentry ever.

Falcon 9 B1056 thankfully suffered no such issues on its much lower-energy reentry and landing at LZ-1. The booster has now completed its second launch and landing a little over 80 days after its flight debut and is already being ‘broken over’ (a term used by SpaceX to describe the process of preparing a recovered booster for horizontal transport) at the Landing Zone, the first step – after landing, of course – towards reuse.

Thanks to that successful second launch and landing, itself a milestone for NASA’s acceptance of Falcon 9 Block 5 reusability, B1056 now has a strong shot at becoming the first Falcon 9 booster to launch three NASA missions. Pending a good post-launch inspection and NASA’s go-ahead, B1056’s next flight will likely be a third Cargo Dragon launch (CRS-19) set to occur no earlier than December 2019, hopefully giving SpaceX plenty of time to soothe any NASA concerns heading into the space agency’s first attempted launch on a twice-flown booster.

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.
