SpaceX’s second Super Heavy booster might land in Mechazilla’s arms

Published

on

CEO Elon Musk says that SpaceX could attempt to catch a Super Heavy booster out of mid-air with a tower-sized ‘Mechazilla’ robot as early as Starship’s second orbital launch attempt.

Speaking on Twitter just hours after SpaceX installed said Starship launch tower’s first arms, Musk has thankfully answered a question on the minds of many: how many prototype boosters must be expended? In a move that can be only described as unexpected, SpaceX revealed plans to fully expend its first orbital-class Starship and Super Heavy booster pair in May 2021 FCC filings, confirming (or strongly implying) that no true recovery attempts would be made.

Instead, in what could be described as a quasi-orbital debut, SpaceX intends to launch the first two-stage Starship to an altitude of around 200-300 km (TBD). Like many Falcon boosters, Super Heavy will separate a few minutes after liftoff, flip around, and boost back towards the South Texas coast, where it will attempt a soft landing 20 miles offshore in the Gulf of Mexico. Reading between the lines of Musk’s latest info, depending on the results of that ocean landing attempt, SpaceX might attempt to catch the second flightworthy Super Heavy booster on the very next launch.

Heading towards a similar fate, Starship will continue onwards and upwards like a Falcon upper stage. Based on its FCC application, SpaceX seems to have implied that Starship will stop just short of true orbit – traveling slow enough to passively reenter Earth’s atmosphere before completing a full trip around the planet. Of course, it’s possible that SpaceX simply left out plans for an intentional deorbit burn, but it does make sense that the company might try to lock in safeguards for such an ambitious inaugural test flight.

In other words, if Starship were to fail during the ~80 minutes it would spend coasting in space, its launch trajectory design would more or less passively prevent a Russian roulette scenario reminiscent of China’s recent spate of uncontrolled reentries. The feats facing Super Heavy are thankfully a fair bit simpler, though Starship booster recovery does pose its own hurdles.

In an apparent effort to reduce risk, SpaceX intends to fully expend the first flightworthy Super Heavy (potentially Booster 4) and all 29 of its Raptor engines. There will be no attempt at all to land the booster or its one-of-a-kind engines at land or on a sea-based platform – partly because Elon Musk appears to have endeavored to entirely prevent the installation – and, perhaps, the design and assembly – of legs. Instead, in one of the eccentric executive’s less intuitive gambles as of late, SpaceX will entirely dispense of more than half a decade of experience landing 90+ Falcon boosters on legs to attempt to catch Super Heavy boosters out of the air with house-sized arms tacked onto a 145m (~475 ft) tall tower.

No different than a hypothetical landing with legs, Super Heavy will still have to boost back to land, coast, and fire up several Raptor engines for a final landing burn – only on tiny handle-like hardpoints and giant moving arms instead of legs and a concrete pad. If catching boosters eventually proves reliable enough to be a worthwhile reinvention of the wheel, the only apparent benefit of the approach will be a slight reduction in Super Heavy’s dry mass.

According to Musk, though, SpaceX might not have to wait long to find out just how viable a recovery method ‘Mechazilla’ really is and will “hopefully” attempt to catch Super Heavy Booster 5 (B5) after Starship’s second orbital launch attempt. Presumably, that attempt is contingent upon FAA approval and on Booster 4 successfully simulating a smooth, accurate landing in the Gulf, as even a minor issue during a catch attempt could catastrophically damage pad hardware that would take months to repair or replace.

For now, it’s almost impossible to say when Starship S20 and Super Heavy B4 will be ready for their orbital launch debut, as that now lies almost solely in the hands of the FAA. In theory, the FAA could complete environmental reviews and grant SpaceX a launch license as few as two or so months from now. In practice, SpaceX could be forced to sit and wait for at least 6-12 more months. Regardless, SpaceX has already begun assembling and staging sections of Ship 21 and Booster 5, so the company could be ready for an extremely rapid turnaround (and Mechazilla’s first catch attempt) after Starship’s orbital launch debut – whenever that may come.

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.
