SpaceX wants to attempt Starship booster catch during first orbital launch

Published

on

An updated document submitted by SpaceX to the US Federal Communications Commission (FCC) has revealed details about the company’s plan for the first Starship booster ‘catch’ attempt.

The document follows a different batch submitted by SpaceX in June 2021, when the company detailed its plans for Starship’s orbital launch debut as background while requesting permission from the FCC to use Starlink dishes for in-flight telemetry. A month earlier, a different request focused on more standard telemetry antennas had already revealed that even if the mission went perfectly, Starship would not fully reach orbit on its first attempted spaceflight. It also confirmed that SpaceX had no intention of recovering the upper stage or Super Heavy booster assigned to Starship’s launch debut – a sort of implicit acknowledgment that success was (then) not expected on the first try.

Twelve months later, SpaceX has submitted an updated overview of Starship’s orbital launch debut in a new request for permission to use multiple Starlink dishes on both stages. While most of the document is the same, a few particular details have changed about Super Heavy’s role in the mission.

This time around, SpaceX says that the Super Heavy booster will “will separate[,] perform a partial return[,] and land in the Gulf of Mexico or return to Starbase and be caught by the launch tower.” Prior to this document, SpaceX’s best-case plans for the first Super Heavy booster to launch never strayed from a controlled splashdown in the Gulf of Mexico – potentially demonstrating that it would be safe to attempt booster recovery on the next launch but all but guaranteeing that the first booster would be lost at sea.

A year later, SpaceX appears to be a bit more confident and wants to leave itself the option to attempt to recover the first Super Heavy booster that launches. However, the company has dramatically complicated the process of testing early Super Heavy and Starship recovery (and thus reuse) by fully removing traditional and predictable landing legs and designing its latest prototypes such that the only way they can be recovered in one piece is with a giant mechanized ‘launch tower’ nicknamed Mechazilla.

The launch tower and its three mobile arms will play a crucial role in all aspects of orbital Starship launches. The first arm swings out to brace Super Heavy for Starship installation and connect the upper stage to power, propellant supplies, and other launch pad utilities. A more exotic pair of arms nicknamed ‘chopsticks’ has a more complex job. On top of using the chopsticks to lift, stack, and demate Starships and Super Heavy boosters and almost any weather and wind conditions, SpaceX wants to use the arms as an incredibly complex and precarious rocket recovery system.

For a booster or Starship “catch,” the rocket will approach the tower, enter the gap between the splayed arms, hover in place while the arms close around it, and eventually come to rest on hardpoints that appear to offer about as much surface area as a coffee table. Based on a simulation of the process shown by Elon Musk, calling it a “catch” is a misnomer, as the arms will mainly move in one dimension (open/close) and can’t actually ‘grab’ the rocket in any real sense. As built and shown, they are closer to a tiny fixed landing platform capable of minor last-second positional adjustments.

Eventually, the chopsticks could shave a small amount of time off of post-recovery processing, removing the need for a crane (or the same arms) to attach to a landed booster or ship. They could also shave off the dry mass required for landing legs, though all interplanetary ships will still need legs. However, they will also inherently make proving their own efficacy a nightmare. By all appearances, the current recovery mechanisms on the arms and the landing hardpoints on ships and boosters mean that a ‘catch’ could fail if either stage is more than a foot or two from a perfect bullseye or rotated a few degrees in the wrong direction. With the method SpaceX has devised, even the tiniest error could easily end with a massive, pressurized, partially-fueled rocket destroying the chopsticks and plummeting a few hundred feet to the ground, guaranteeing an explosion that could damage surrounding infrastructure or start fires that might.

In the event of larger anomalies during a landing attempt, Starship or Super Heavy could accidentally impact the launch tower, damaging or even outright destroying the skyscraper-sized structure. Ultimately, the immense risk posed by any catch attempt means that unless SpaceX has miraculously gotten the design of everything involved nearly perfect on its first try, the company will have to be extraordinarily cautious and expend a large number of ships and boosters to avoid rendering its only Starship launch tower unusable.

At least to some extent, SpaceX likely knows this and Super Heavy would likely need to be in excellent health and perform perfectly during the ascent and boostback portions of its launch debut to be cleared for a catch attempt. Ultimately, Starship’s first orbital launch could end up being even more of a spectacle than it’s already guaranteed to be.

Tesla supplier Samsung preps for AI5 production with 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.

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.

Tesla discloses interesting collaboration partner for Supercharging

This BOXABL collaboration would be a great way to add a rest stop to a rural Supercharging location, and could lead to more of these chargers across the U.S.

Tesla disclosed an interesting collaboration partner in an SEC filing, which looks like an indication of a potential project at Supercharger sites.

Tesla said on Tuesday in the filing that it was entering an agreement with BOXABL to design and build a Micromenity structure. Simply put, this is a modular building, usually a few hundred square feet in size, and it has been seen at Superchargers in Europe.

In Magnant, France, Tesla opened a small building at a Supercharger that is available to all EV owners. There are snacks and drinks inside, including ice cream, coffee, a gaming console, and restrooms. It gives people an opportunity to get up and out of their cars while charging.

This building was not built by BOXABL, but instead by bk World Lounges. It is likely the final Supercharging stop before people get to Paris, as it is located 250 kilometers, or 155 miles, from the City of Light.

Magnant has 56 stalls, so it is a large Supercharging stop compared to most. The building could be a sign of things to come, especially as Tesla has opened up larger Supercharger stations along major roadways.

It is for just a single building, as the Scope of Work within the filing states “a comprehensive package for one Micromenity building.”

Superchargers are commonly located at gas stations, shopping centers, and other major points of interest. However, there are some stops that are isolated from retail or entertainment.

This BOXABL collaboration would be a great way to add a rest stop to a rural Supercharging location, and could lead to more of these chargers across the U.S.

Tesla has done a lot of really great things for Supercharging this year.

Along with widespread expansion, the company launched the “Charging Passport” this week, opened the largest Supercharger in the world in Lost Hills, California, with 168 chargers, opened the Tesla Diner, a drive-in movie restaurant in Los Angeles, and initiated access to the infrastructure to even more automakers.

Tesla CEO Elon Musk confirms Robotaxi safety monitor removal in Austin: here’s when

Musk has made the claim about removing Safety Monitors from Tesla Robotaxi vehicles in Austin three times this year, once in September, once in October, and once in November.

Tesla CEO Elon Musk confirmed on Tuesday at the xAI Hackathon that the company would be removing Safety Monitors from Robotaxis in Austin in just three weeks.

This would meet Musk’s timeline from earlier this year, as he has said on several occasions that Tesla Robotaxis would have no supervision in Austin by the end of 2025.

On Tuesday, Musk said:

“Unsupervised is pretty much solved at this point. So there will be Tesla Robotaxis operating in Austin with no one in them. Not even anyone in the passenger seat in about three weeks.”

Musk has made the claim about removing Safety Monitors from Tesla Robotaxi vehicles in Austin three times this year, once in September, once in October, and once in November.

In September, he said:

“Should be no safety driver by end of year.”

On the Q3 Earnings Call in October, he said:

“We are expecting ot have no safety drivers in at least large parts of Austin by the end of this year.”

Finally, in November, he reiterated the timeline in a public statement at the Shareholder Meeting:

“I expect Robotaxis to operate without safety drivers in large parts of Austin this year.”

Currently, Tesla uses Safety Monitors in Austin in the passenger’s seat on local roads. They will sit in the driver’s seat for highway routes. In the Bay Area ride-hailing operation, there is always a Safety Monitor in the driver’s seat.

Three weeks would deliver on the end-of-year promise, cutting it close, beating it by just two days. However, it would be a tremendous leap forward in the Robotaxi program, and would shut the mouths of many skeptics who state the current iteration is no different than having an Uber.

Tesla has also expanded its Robotaxi fleet this year, but the company has not given exact figures. Once it expands its fleet, even more progress will be made in Tesla’s self-driving efforts.
