All major aspects of SpaceX’s most recent Falcon 9 Block 5 booster recovery have been documented from start to finish, offering a solid glimpse into the work that actually goes into getting a rocket booster from the deck of a SpaceX drone ship to one of the company’s many hangars for inspections, repairs, and refurbishment.

Filmed by USLaunchReport, a SpaceX-focused nonprofit staffed by U.S. veterans, the group’s coverage of a variety of SpaceX events may not always offer the highest production quality, but the sheer tenacity and patience of those behind the cameras allow them to capture unique and interesting events that almost nobody else is keen to wait around for.

Over the course of four videos focused on SpaceX’s recovery of Falcon 9 Block 5 booster B1047, USLaunchReport offered good views of four major events that occur during all rocket recovery operations: the drone ship’s return to port, Falcon 9’s move from ship to shore, the booster’s landing leg removal (or retraction), and the booster’s transfer from a vertical to horizontal orientation and transport by road back to a SpaceX hangar.

Of Course I Still Love You arrives at Port Canaveral

As with all of Falcon 9’s drone ship landings, B1047 came to a rest on a station-keeping OCISLY several hundred miles east of the Florida coast, coincidentally landing directly in front of a giant rainbow cued by rain clouds, both visible in the background. In theory, B1047’s second landing should by no means be the rocket’s last: if Falcon 9 Block 5’s first stage upgrades are as successful as they hoped to be, the rocket could well see a productive life of 100 launches or more between now and BFR’s complete takeover.

For at least the next 5-10 years, however, SpaceX followers will continue to be treated to spectacular Falcon 9 and Falcon Heavy booster recoveries, particularly the moment when each booster sails through the narrow mouth of Port Canaveral or Port of Los Angeles, offering spectators almost unbeatable views of just-landed SpaceX rockets.

Falcon 9’s lift from ship to shore

Soon after the drone ship docks in port, SpaceX recovery technicians install a brace and lifting jig that attaches to Falcon 9’s booster interstage, using the same mechanisms that connect the first stage to the second stage prior to stage separation. The interstage’s mechanical actuators are strong enough to support – at a minimum – the entire weight of an empty Falcon 9 booster, allowing SpaceX to simply attach the jig and lift Falcon 9 off of the drone ship with any number of large but commercially available cranes.

Rather than directly lowering the rocket and allowing it to rest directly on its landing legs again, SpaceX technicians make use of a custom-built stand that acts as a sort of barebones, static replica of the mounts Falcon 9s are attached to at SpaceX launch pads. Structurally optimized to allow Falcon 9 and Heavy to be held down on the launch pad while operating at full thrust, a series of four solid-metal attachment points interface with those hold-down clamps, attach to Falcon 9’s four landing legs, and offer an easily accessible and structurally sound method of sitting a booster upright (sans legs) and maneuvering it during recovery operations.

 

Once Falcon 9 is sat stably atop its recovery stand, SpaceX technicians remove the rocket’s four landing legs and their associated telescoping deployment assemblies. While SpaceX has recently begun to attempt the in-situ retraction and stowage of Falcon 9 landing legs once returned to land, a number of experimental retraction attempts appear to have produced less than satisfactory results. This time around, the retraction jig was visibly stripped and SpaceX technicians did not attempt any leg retractions. However, those recovery technicians are now so experienced and familiar with the optimized procedures that Falcon 9 booster can go from port arrival to horizontal transport to a SpaceX hangar in just a little over 48 hours, and that trend continued with B1047.2.

From | to __

Although Falcon 9 and Heavy rockets come into their prime once vertical, the rockets spend the vast majority of their lives horizontal, either in transport from facility to facility or stationary inside a SpaceX hangar, awaiting launch, undergoing integration, or being refurbished. Translating Falcon 9’s massive ~30-ton, 135-foot-tall (41m) booster from vertical to horizontal is a feat within itself, requiring the coordinated use of two large cranes, multiple technicians with guidelines, and one of several giant booster transport jigs owned by SpaceX.

SpaceX’s seasoned recovery technicians make it look easy, but the reality is in almost polar opposition. The fact that Falcon 9’s structure is built primarily of aluminum-lithium alloy tanks with walls maybe half a centimeter (~5 mm) thick certainly doesn’t make this process any easier, as even the slightest misstep or tank depressurization (Falcon 9 is almost always pressurized with nitrogen when horizontal) could structurally compromise the rocket and result in irreparable damage.

The cherry on top

A reliable crowdpleaser, the last critical step in any Falcon 9 or Falcon Heavy recovery is the booster’s careful transport – by road – from its port of call (or landing zone) to a dedicated SpaceX hangar (or factory), where the rocket can be far more thoroughly inspected, repaired, and maintained between launches. With Falcon 9 Block 5’s May 2018 introduction, the latter segment has become more important than ever before, as the upgraded rockets are already routinely conducting launches with as few as three months between them, bringing SpaceX closer than ever before to realizing a long-term aspiration of operating a fleet of rapidly and (relatively) easily reusable orbital-class rockets.

Often slowly driving just a few dozen feet from passing bystanders and traffic, this short few-mile trip from Port Canaveral to either Kennedy Space Center (KSC) or Cape Canaveral Air Force Station (CCAFS) is typically done with Falcon 9 boosters entirely uncovered, aside from nine small booties that cover their nine Merlin 1D engines. Without unique and easily missed moments like this, it might well be just shy of impossible to get fewer than several hundred feet away from an operational SpaceX rocket, certainly a luxury but one that would still be sorely missed.

All things considered, the crew at USLaunchReport ought to be thanked for their relentless patience and commitment to getting the shot. For those of us who mean to resist the tendency for SpaceX’s sheer inertia to rapidly make the extraordinary all but mundane, these long, highly detailed, and often esoteric videos will (hopefully) never get old.

Tesla Full Self-Driving v14.3.6 review: a rare regression, but some bright spots

Published

on

Credit: Tesla

Tesla released Full Self-Driving version 14.3.6 last week, and after what was potentially one of the best FSD releases in v14.3.5, there has been a bit of a regression. While there are some bright spots, the changes made to v14.3.6 seem to have backtracked some behaviors.

Overall, it is hard to really complain about FSD in any sense; it has revolutionized how I travel literally anywhere. According to my self-driving app, the last time I went a day without using it was 59 days ago.

However, I think it’s also important to recognize when things are just plain bad with FSD. There are times it does truly mind-boggling things, and I’ll dive into those here. Additionally, I only had these issues on local roads, not on highways. Highway operation, generally, is always incredible other than the occasional complaint about speed or left lane camping.

With those things being said, my personal experience may not represent others’ experiences. A handful of people have said they have had a similar experience on v14.3.6, while others have said it is more than normal.

Turning Hesitancy, Inaccuracy

I’ve noticed more inaccuracy turning into multi-lane stretches of road than in any version I can remember. I’ve had at least three instances of FSD turning into a stretch of roadway that has two or more lanes, and not selecting a lane confidently as it has in past versions.

Instead, the car will drive over one of the dashed road lines, and the steering wheel will jerk back and forth before picking the lane. It should be said that it has always picked the correct lane when choosing based on the navigation, but it is still very indecisive. The steering wheel jerking is reminiscent of some of the later versions of v13.

I admit I really hate to see the steering wheel jerking come back. However, I think when Tesla releases v14.3.7, it won’t be present. When there are occurrences of it in FSD versions, it is usually resolved by the following release.

FSD Disregards Manual Turn Signals

This is my biggest bone to pick with FSD other than Navigation issues, but this one seems like it would be such an easy fix.

If Tesla is going to put the word “Supervised” on the end of “Full Self-Driving,” then when I tell the car to do something, it should do it. If I input an increase in speed by pressing the accelerator, the car will immediately respond. It does not disregard my input because it feels it is traveling at the right speed.

FSD should never disobey and turn off turn signals that the driver inputs. Trying to direct the car into the correct lane, I had initiated the left turn signal not once, not twice, but three times, with the car turning it off all three times and continuing in a lane that would end in just one block. The only solution at this point would be to zipper merge.

This goes back to the fact that self-driving’s biggest bottleneck might be rider preference. A zipper merge might have been more than reasonable, might have saved me time that I spent sitting through an additional light cycle, and might be something many drivers would do. I was in no hurry, I traditionally do not try to zipper merge because it feels inconsiderate, and lastly, the car should have just followed my input.

This caused me to disengage and drive manually the rest of the way home. Sometimes I just do not need FSD to try to pass every car it can at intersections.

Bird Braking is a Thing of the Past

The big complaint with recent versions of Full Self-Driving has been what we’ve coined as “bird braking,” which is when the car will brake suddenly as a bird flies past.

There have been zero issues with this so far in v14.3.6, which is an excellent improvement.

FSD Might Already Be Taking Note of Driver Preferences

Another thing I have noticed over the past few days is that v14.3.6 seems to already be taking my preferences with navigation into account.

This is something that is supposed to be rolling out with the Summer Update, but I have a hunch it’s already present and might have been included in this v14.3.6 build. On Friday, FSD pulled into an entrance to a local convenience store that it had never attempted to go into before.

Typically, I manually pull into this entrance because it avoids heavy cross traffic at the main entrance. FSD has always chosen that congested main entrance.

Additionally, FSD has pulled into my assigned parking spot at my townhouse community on multiple occasions with this release. This is something that used to happen ocassionally, but not consistently.

It also navigated back to the same convenience store last night, drove through crazy cars scrambling to gas pumps, navigated out of the parking lot correctly, drove me home, and, once again, parked in my assigned spot.

As previously stated, this release just seems to have a few things that need to be brought to Tesla’s attention, and also to make others who use FSD aware of some things that I’ve experienced. I look forward to the next release that will remedy these issues, just as Tesla has always done in the past.

Elon Musk’s massive Terafab project, which will be the first true conglomeration between each of his major entities, is set to get its final location soon, the CEO said on Tesla’s recent earnings call.

“The Terafab, we expect to announce a location soon, and provide more details about our plans in that regard. We’ll leave that to the product, the launch announcement rather than try to squeeze it into an earnings call,” Musk said last Wednesday.

Tesla Terafab set for launch: Inside the $20B AI chip factory that will reshape the auto industry

Terafab was announced by Musk back in March and was essentially a massive, vertically integrated semiconductor manufacturing project that would provide all the chips the three companies needed for their AI initiatives without needing third-party companies.

The plant will produce over 1 terawatt of AI compute each year, and will help back up projects like Optimus, Full Self-Driving, and other AI-based projects that Musk’s companies are working on.

In April, less than a month after the project was launched, Intel announced it would join the project, contributing manufacturing expertise and consulting to Terafab as a whole. Intel is one of three chip manufacturers that produce sub-5 nanometer chips at scale. TSMC and Samsung are the other two.

However, there was no true indication of where Terafab would end up, but most believe it will likely be somewhere in Texas. Business Insider has reported that SpaceX plans to build out Terafab in Grimes County, Texas, but this is unconfirmed.

Musk confirmed recently that it would not be on Giga Texas property, as it is simply too large.

Terafab holds much of Musk’s grand ambitions for the future within its construct. It holds so much responsibility for the future and the biggest projects that Musk’s companies can imagine.

“I think this is a very big announcement and it deserves to have its own day in the spotlight and not be squeezed into an earnings call,” he said. “I do think Terafab is going to be an amazing initiative and a necessary one, and one without which we will be constrained in our ability to scale Optimus production, because we simply won’t have enough AI chips.”

He continued by stating that Terafab is necessary for scaling Optimus, which Musk said could be the biggest product of any kind of all time. “It’s crucial to solve that, and we’ll have to solve memory, logic, and packaging in order to scale Optimus.”

Elon Musk reveals SpaceX performed secret Starship test on Flight 13

SpaceX performed a secret test on a specific portion of Starship with its recent 13th test flight last week, CEO Elon Musk revealed.

Starship’s 13th test flight took place last Friday, and in many aspects, it was one of the most overwhelmingly successful launches in the project’s history.

All of the mission objectives were met without incident, both the Super Heavy Booster and Ship managed to perform safe splashdowns in the Gulf of America and the Indian Ocean, respectively, and the deployment of Starlink satellites came and went without any complications.

However, there was more on the agenda for SpaceX with Flight 13. Musk revealed an internal test of the ship’s heat shield tiles, as the space exploration company wanted to push them to the limits after previous issues.

Many noticed that Starship’s initial launch seemed to be more accelerated than normal, and that was not a mistake. Musk revealed that SpaceX decided to give Flight 13 an intentionally aggressive acceleration rate in an effort to test how well the tiles would remain attached to the ship:

SpaceX had issues with some of the heat shield tiles remaining attached early on in the Starship program. The first six test flights presented some kind of anomaly with them, so the company’s big focus with them was to figure out a way to keep them intact through the duration of the flight.

Things truly improved as Flight 10 showed that ceramic tiles generally stayed attached to the ship far better due to refined attachment, as SpaceX utilized pins instead of adhesives. Flights 10 through 13 truly showed some clear progress with the heat shield tiles, and this latest test seems to be where some real progress was noticed, especially by Musk.

The 13th Starship launch last Friday was the second with Starship V3, SpaceX’s latest and greatest iteration of the spacecraft. Goals and ambitions are getting even grander as the project continues to progress. Musk has already hinted that SpaceX will likely try to catch Starship with Flight 14.
