SpaceX ramps South Texas activity to prepare for 2019 BFR spaceship testing

Published

on

At the same time as the hardware for SpaceX’s first BFR spaceship is entering the early stages of manufacturing, the company’s South Texas test facility is slowly taking shape after more than 18 months of what can be fairly described as hibernation.

The likeliest location for a near-future spaceship test stand or pad has also experienced a comparatively vast influx of construction workers and general activity that began earlier this month September, nearly two and half years after SpaceX began preparing the unstable coastal wetland with the addition of several hundred tons of soil.

According to a number of posts from local Texans that are also members of a small SpaceX fan group on Facebook, activity around the company’s Boca Chica, Texas facilities has exploded in recent months, and even more so over the last several weeks. SpaceX’s ground tracking facility has harbored the vast majority of attention for some time, particularly following the relatively recent arrival of a massive crane, construction of a shelter for said crane, and the appearance of two massive vacuum-insulated tanks for liquid oxygen (LOX) and liquid methane/natural gas (LNG).

Presently sat beside two large antennae on the Crew Dragon tracking facility’s plot, those propellant tanks are certainly both eye-catching and definitive evidence that something huge and nearby will soon need large quantities of liquid propellant. In the case of the LOX tank, a back-the-envelope estimate suggests that it can hold an obscene 400 metric tons (~900,000 lbs) of liquid oxygen, while the much smaller LNG tank (assumed, not guaranteed) would be capable of holding less than 25,000 kg of liquid methane, thanks mainly to the fact that liquid methane is roughly three times less dense than LOX.

Thankfully, SpaceX’s BFR Raptor engines will nominally burn oxygen and methane at a ratio of approximately 3.8 to 1, meaning that every 1 kg of methane exiting the rocket will be accompanied by 3.8 kg of oxygen. The fact that this ratio is actually larger than the density ratio of LOX and LNG means that the propellant tanks can be almost the same size

Most notably, as described above, is the abrupt return of construction and site preparation activities at what once was expected to be a Falcon 9 and Heavy launch pad. Over the last 24+ months, SpaceX has simply let the lot sit, although in this case, that sitting was rather productive. Known as soil surcharging, the site was essentially leveled, loaded with hundreds of tons of soil, plumbed with drainage pipes, and then left alone up to this point to let gravity do the rest of the work. Put simply, the unsteady soil of coastal Texas was aggressively drained and compacted into something stable enough to build expensive, long-term facilities on.

The hundreds of truckloads it took to bring in the soil will have to be repeated in reverse, removing most of the same soil to leave a level field ready for foundation-laying and series construction. Heavy machinery and construction contractors began arriving earlier this month, indicating that that process is about to begin, after which construction of the facilities that will eventually support Grasshopper-style spaceship testing can begin in earnest. Those BFR hop tests are scheduled to begin no earlier than late 2019.

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.

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.

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.
