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 adds new feature that will be great for crowded parking situations

This is the most recent iteration of the app and was priming owners for the slowly-released Holiday Update.

Tesla has added a new feature that will be great for crowded parking lots, congested parking garages, or other confusing times when you cannot seem to pinpoint where your car went.

Tesla has added a new Vehicle Locator feature to the Tesla App with App Update v4.51.5.

This is the most recent iteration of the app and was priming owners for the slowly-released Holiday Update.

While there are several new features, which we will reveal later in this article, perhaps one of the coolest is that of the Vehicle Locator, which will now point you in the direction of your car using a directional arrow on the home screen. This is similar to what Apple uses to find devices:

In real time, the arrow gives an accurate depiction of which direction you should walk in to find your car. This seems extremely helpful in large parking lots or unfamiliar shopping centers.

Getting to your car after a sporting event is an event all in itself; this feature will undoubtedly help with it:

Tesla’s previous app versions revealed the address at which you could locate your car, which was great if you parked on the street in a city setting. It was also possible to use the map within the app to locate your car.

However, this new feature gives a more definitive location for your car and helps with the navigation to it, instead of potentially walking randomly.

It also reveals the distance you are from your car, which is a big plus.

Along with this new addition, Tesla added Photobooth features, Dog Mode Live Activity, Custom Wraps and Tints for Colorizer, and Dashcam Clip details.

All in all, this App update was pretty robust.

Tesla CEO Elon Musk shades Waymo: ‘Never really had a chance’

Published

Tesla CEO Elon Musk shaded Waymo in a post on X on Wednesday, stating the company “never really had a chance” and that it “will be obvious in hindsight.”

Tesla and Waymo are the two primary contributors to the self-driving efforts in the United States, with both operating driverless ride-hailing services in the country. Tesla does have a Safety Monitor present in its vehicles in Austin, Texas, and someone in the driver’s seat in its Bay Area operation.

Musk says the Austin operation will be completely void of any Safety Monitors by the end of the year.

With the two companies being the main members of the driverless movement in the U.S., there is certainly a rivalry. The two have sparred back and forth with their geofences, or service areas, in both Austin and the Bay Area.

While that is a metric for comparison now, ultimately, it will not matter in the coming years, as the two companies will likely operate in a similar fashion.

Waymo has geared its business toward larger cities, and Tesla has said that its self-driving efforts will expand to every single one of its vehicles in any location globally. This is where the true difference between the two lies, along with the fact that Tesla uses its own vehicles, while Waymo has several models in its lineup from different manufacturers.

The two also have different ideas on how to solve self-driving, as Tesla uses a vision-only approach. Waymo relies on several things, including LiDAR, which Musk once called “a fool’s errand.”

This is where Tesla sets itself apart from the competition, and Musk highlighted the company’s position against Waymo.

Jeff Dean, the Chief Scientist for Google DeepMind, said on X:

“I don’t think Tesla has anywhere near the volume of rider-only autonomous miles that Waymo has (96M for Waymo, as of today). The safety data is quite compelling for Waymo, as well.”

Musk replied:

“Waymo never really had a chance against Tesla. This will be obvious in hindsight.”

Tesla stands to have a much larger fleet of vehicles in the coming years if it chooses to activate Robotaxi services with all passenger vehicles. A simple Over-the-Air update will activate this capability, while Waymo would likely be confined to the vehicles it commissions as Robotaxis.

Tesla supplier Samsung is preparing to manufacture the AI5 chip, which will launch the company’s self-driving efforts even further, with its latest move.

According to a new report from Sedaily, Samsung is accelerating its preparation for U.S. production of the AI5 chips by hiring veteran engineers for its Customer Engineering team, which will help resolve complex foundry challenges, stabilize production and yields, and ensure manufacturing goes smoothly for the new project.

The hiring push signals that Tesla’s AI5 project is moving forward quickly at Samsung, which was one of two suppliers to win a contract order from the world’s leading EV maker.

TSMC is the other. TSMC is using its 3nm process, reportedly, while Samsung will do a 2nm as a litmus test for the process.

The different versions are due to the fact that “they translate designs to physical form differently,” CEO Elon Musk said recently. The goal is for the two to operate identically, obviously, which is a challenge.

Some might remember Apple’s A9 “Chipgate” saga, which found that the chips differed in performance because of different manufacturers.

The AI5 chip is Tesla’s next-generation hardware chip for its self-driving program, but it will also contribute to the Optimus program and other AI-driven features in both vehicles and other projects. Currently, Tesla utilizes AI4, formerly known as HW4 or Hardware 4, in its vehicles.

Tesla teases new AI5 chip that will revolutionize self-driving

AI5 is specialized for use by Tesla as it will work in conjunction with the company’s Neural Networks, focusing on real-time inference to make safe and logical decisions during operation.

Musk said it was an “amazing design” and an “immense jump” from Tesla’s current AI4 chip. It will be roughly 40 times faster, and have 8 times the raw compute, with 9 times the memory capacity. It is also expected to be three times as efficient per watt as AI4.

AI5 will make its way into “maybe a small number of units” next year, Musk confirmed. However, it will not make its way to high-volume production until 2027. AI5 is not the last step, either, as Musk has already confirmed AI6 would likely enter production in mid-2028.
