SpaceX putting the finishing touches on Starship’s orbital launch pad

SpaceX appears to have begun tying up a number of loose ends at Starship’s first orbital launch site, potentially setting the stage for major rocket testing CEO Elon Musk has stated could begin next month.

The list of tasks started or completed in just the last week or two is significant and each one is singularly focused on similar goals: pave the way for SpaceX to finish testing the first orbital-class Starship and Super Heavy booster and prepare for the first orbital launch attempt of the largest rocket ever built. While SpaceX’s progress towards those goals over the last several months has been decidedly slow relative to the pace of similar work completed in the very recent past, the nominal timeline Musk recently sketched out suggests that things could once again start to happen at a dizzying rate.

Launch Tower

Kicking off a jam-packed two weeks of minor to major finishing touches, SpaceX rigged Starbase orbital launch tower’s rocket-catching arms to a system of pulleys, and ‘drawworks’ in a process known as “reeving.” Thousands of feet of rope were first threaded from up, down, and through the ~145m (~440 ft) tower to act as a temporary guide for the next step. Once fully rigged, anchored, and attached to the start of the steel cable actually meant to operate the system, the tower’s ‘drawworks’ was activated for the first time to reel in the guide rope – simultaneously installing the steel cable. By November 9th, the process was more or less complete, leaving the steel cable firmly attached to the tower’s giant rocket-catching arms and able to carry their significant weight.

SpaceX hasn’t quite finished installing those arms and does not appear to have picked up the slack in the cable that will eventually lift them up and down the tower, but the arm assembly’s first real move is likely just a few weeks away. Notably, a bit of scaffolding around the tower’s ‘legs’ still needs to be removed before the catch arms can freely roll up and down rails welded to their exteriors. SpaceX will also need to complete shakedown testing of the arms themselves, ensuring that the massive structures’ hydraulic, electrical, and mechanical systems are all working properly.

In the near future, those arms will be used to grab, lift, and install Super Heavy boosters and stack Starships on top of them, while SpaceX also hopes to eventually use them to catch boosters and ships out of mid-air. At least for the former role, a separate arm visible about halfway up the tower in the photo above will also be crucial. Known as the tower’s Starship quick-disconnect (QD) arm or claw, SpaceX has also made significant progress on the structure, practically completing it in the last few days.

Designed to fuel Starship and stabilize the top of Super Heavy with its claw, the Starship ‘QD arm’ is also able to swing left and right both to quickly back away during launches and to make room for the catch arms during rocket catches and ship/booster stacking operations. Last week, SpaceX technicians finished plumbing the arm, which requires thousands of feet of insulated steel tubes to connect to the pad’s propellant tanks. This week, on November 23rd, SpaceX installed the last major component of the arm – the actual quick disconnect (QD) mechanism that will connect to Starship to supply power, communications, and propellant.

A few small actuators likely still need to be installed and the QD mechanism itself will have to be fully connected to pad systems but the QD arm now appears to be more or less complete and should soon be ready to fuel Starships installed on top of Super Heavy boosters.

Launch Mount

Last but not least, SpaceX performed multiple tests of the pad’s ‘orbital launch mount’ – the giant, steel structure that will support Super Heavy, hold the booster down during testing and before liftoff, and supply it with thousands of tons of propellant. On November 21st, SpaceX completed the first of those tests, seemingly venting an unknown gas out of the mount. More likely than not, it was the first simultaneous test of all 20 of the mounts Raptor Boost engine gas supplies, which – having no need to reignite in flight – will rely on ground gas supplies for ignition. Each of Super Heavy’s 20 outer Raptor engines has a small umbilical and quick disconnect mechanism, resulting in what is likely the most mechanically complex rocket launch mount ever built.

On November 22nd, the orbital launch mount’s booster quick disconnect panel actuated for the first time, showing off the first glimpse of how it will move forward to connect to Super Heavy after a booster is installed on the mount. To prevent its sensitive components from being practically incinerated each launch, the mount’s QD panel will also need to rapidly move away from Super Heavy just before liftoff.

Aside from simply avoiding direct impingement from the several-thousand-degree plume created by 29-33 Raptor engines at full thrust, that movement will also tie into some kind of hood, seamlessly actuating hatches that will close to truly protect the device. That hood was itself spotted for the first time on November 21st and will likely be installed on the launch mount and over the naked QD mechanism in the very near future.

Finally, over the last week or so, SpaceX has begun installing a number of new pipes on and around the launch mount, likely assembling a water deluge system that will help manage the extreme thermal and acoustic environment created by the most powerful rocket in history shortly before and after liftoff. When activated, a spray bar circling the mount’s full interior circumference will likely unleash several tons of water per second in a giant artificial waterfall, hopefully preventing Super Heavy from damaging itself with the sheer sound produced by its Raptor engines or violently eroding the surrounding pad or launch mount legs with its plume.

Ultimately, once all the tower, arm, and mount work described above is completed, the only obvious thing standing between the orbital launch pad and the first Super Heavy booster testing and first orbital Starship launch will be the delivery of liquid methane fuel, which could easily begin any day now.

Tesla hints toward Premium Robotaxi offering with Model S testing

Why Tesla has chosen to use a couple of Model S units must have a reason; the company is calculated in its engineering and data collection efforts, so this is definitely more than “we just felt like giving our drivers a change of scenery.”

Tesla Model S vehicles were spotted performing validation testing with LiDAR rigs in California today, a pretty big switch-up compared to what we are used to seeing on the roads.

Tesla utilizes the Model Y crossover for its Robotaxi fleet. It is adequately sized, the most popular vehicle in its lineup, and is suitable for a wide variety of applications. It provides enough luxury for a single rider, but enough room for several passengers, if needed.

However, the testing has seemingly expanded to one of Tesla’s premium flagship offerings, as the Model S was spotted with the validation equipment that is seen entirely with Model Y vehicles. We have written several articles on Robotaxi testing mules being spotted across the United States, but this is a first:

Why Tesla has chosen to use a couple of Model S units must have a reason; the company is calculated in its engineering and data collection efforts, so this is definitely more than “we just felt like giving our drivers a change of scenery.”

It seems to hint that Tesla could add a premium, more luxury offering to its Robotaxi platform eventually. Think about it: Uber has Uber Black, Lyft has Lyft Black. These vehicles and services are associated with a more premium cost as they combine luxury models with more catered transportation options.

Tesla could be testing the waters here, and it could be thinking of adding the Model S to its fleet of ride-hailing vehicles.

Reluctant to remove the Model S from its production plans completely despite its low volume contributions to the overall mission of transitioning the world to sustainable energy, the flagship sedan has always meant something. CEO Elon Musk referred to it, along with its sibling Model X, as continuing on production lines due to “sentimental reasons.”

However, its purpose might have been expanded to justify keeping it around, and why not? It is a cozy, premium offering, and it would be great for those who want a little more luxury and are willing to pay a few extra dollars.

Of course, none of this is even close to confirmed. However, it is reasonable to speculate that the Model S could be a potential addition to the Robotaxi fleet. It’s capable of all the same things the Model Y is, but with more luxuriousness, and it could be the perfect addition to the futuristic fleet.

Rivian unveils self-driving chip and autonomy plans to compete with Tesla

Rivian, a mainstay in the world of electric vehicle startups, said it plans to roll out an Autonomy+ subscription and one-time purchase program, priced at $49.99 per month and $2,500 up front, respectively, for access to its self-driving suite.

Rivian unveiled its self-driving chip and autonomy plans to compete with Tesla and others at its AI and Autonomy Day on Thursday in Palo Alto, California.

Rivian, a mainstay in the world of electric vehicle startups, said it plans to roll out an Autonomy+ subscription and one-time purchase program, priced at $49.99 per month and $2,500 up front, respectively, for access to its self-driving suite.

CEO RJ Scaringe said it will learn and become more confident and robust as more miles are driven and it gathers more data. This is what Tesla uses through a neural network, as it uses deep learning to improve with every mile traveled.

He said:

“I couldn’t be more excited for the work our teams are driving in autonomy and AI. Our updated hardware platform, which includes our in-house 1600 sparse TOPS inference chip, will enable us to achieve dramatic progress in self-driving to ultimately deliver on our goal of delivering L4. This represents an inflection point for the ownership experience – ultimately being able to give customers their time back when in the car.”

At first, Rivian plans to offer the service to personally-owned vehicles, and not operate as a ride-hailing service. However, ride-sharing is in the plans for the future, he said:

“While our initial focus will be on personally owned vehicles, which today represent a vast majority of the miles to the United States, this also enables us to pursue opportunities in the rideshare space.”

The Hardware

Rivian is not using a vision-only approach as Tesla does, and instead will rely on 11 cameras, five radar sensors, and a single LiDAR that will face forward.

It is also developing a chip in-house, which will be manufactured by TSMC, a supplier of Tesla’s as well. The chip will be known as RAP1 and will be about 50 times as powerful as the chip that is currently in Rivian vehicles. It will also do more than 800 trillion calculations every second.

RAP1 powers the Autonomy Compute Module 3, known as ACM3, which is Rivian’s third-generation autonomy computer.

ACM3 specs include:

  • 1600 sparse INT8 TOPS (Trillion Operations Per Second).
  • The processing power of 5 billion pixels per second.
  • RAP1 features RivLink, a low-latency interconnect technology allowing chips to be connected to multiply processing power, making it inherently extensible.
  • RAP1 is enabled by an in-house developed AI compiler and platform software

As far as LiDAR, Rivian plans to use it in forthcoming R2 cars to enable SAE Level 4 automated driving, which would allow people to sit in the back and, according to the agency’s ratings, “will not require you to take over driving.”

More Details

Rivian said it will also roll out advancements to the second-generation R1 vehicles in the near term with the addition of UHF, or Universal Hands-Free, which will be available on over 3.5 million miles of roadway in the U.S. and Canada.

Rivian will now join the competitive ranks with Tesla, Waymo, Zoox, and others, who are all in the race for autonomy.

Tesla owners in California, Oregon, and Arizona can now use Lemonade Insurance, the firm that recently said it could cover Full Self-Driving miles for “almost free.”

Lemonade, which offered the new service through its app, has three distinct advantages, it says:

  • Direct Connection for no telematics device needed
  • Better customer service
  • Smarter pricing

The company is known for offering unique, fee-based insurance rates through AI, and instead of keeping unclaimed premiums, it offers coverage through a flat free upfront. The leftover funds are donated to charities by its policyholders.

On Thursday, it announced that cars in three states would be able to be connected directly to the car through its smartphone app, enabling easier access to insurance factors through telematics:

Tesla recently was offered “almost free” coverage for Full Self-Driving by Lemonade’s Shai Wininger, President and Co-founder, who said it would be “happy to explore insuring Tesla FSD miles for (almost) free.”

The strategy would be one of the most unique, as it would provide Tesla drivers with stable, accurate, and consistent insurance rates, while also incentivizing owners to utilize Full Self-Driving for their travel miles.

Tesla Full Self-Driving gets an offer to be insured for ‘almost free’

This would make FSD more cost-effective for owners and contribute to the company’s data collection efforts.

Data also backs Tesla Full Self-Driving’s advantages as a safety net for drivers. Recent figures indicate it was nine times less likely to be in an accident compared to the national average, registering an accident every 6.36 million miles. The NHTSA says a crash occurs approximately every 702,000 miles.

Tesla also offers its own in-house insurance program, which is currently offered in twelve states so far. The company is attempting to enter more areas of the U.S., with recent filings indicating the company wants to enter Florida and offer insurance to drivers in that state.
