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 investors will be shocked by Jim Cramer’s latest assessment

Jim Cramer is now speaking positively about Tesla, especially in terms of its Robotaxi performance and its perception as a company.

Tesla investors will be shocked by analyst Jim Cramer’s latest assessment of the company.

When it comes to Tesla analysts, many of them are consistent. The bulls usually stay the bulls, and the bears usually stay the bears. The notable analysts on each side are Dan Ives and Adam Jonas for the bulls, and Gordon Johnson for the bears.

Jim Cramer is one analyst who does not necessarily fit this mold. Cramer, who hosts CNBC’s Mad Money, has switched his opinion on Tesla stock (NASDAQ: TSLA) many times.

He has been bullish, like he was when he said the stock was a “sleeping giant” two years ago, and he has been bearish, like he was when he said there was “nothing magnificent” about the company just a few months ago.

Now, he is back to being a bull.

Cramer’s comments were related to two key points: how NVIDIA CEO Jensen Huang describes Tesla after working closely with the Company through their transactions, and how it is not a car company, as well as the recent launch of the Robotaxi fleet.

Jensen Huang’s Tesla Narrative

Cramer says that the narrative on quarterly and annual deliveries is overblown, and those who continue to worry about Tesla’s performance on that metric are misled.

“It’s not a car company,” he said.

He went on to say that people like Huang speak highly of Tesla, and that should be enough to deter any true skepticism:

“I believe what Musk says cause Musk is working with Jensen and Jensen’s telling me what’s happening on the other side is pretty amazing.”

Robotaxi Launch

Many media outlets are being extremely negative regarding the early rollout of Tesla’s Robotaxi platform in Austin, Texas.

There have been a handful of small issues, but nothing significant. Cramer says that humans make mistakes in vehicles too, yet, when Tesla’s test phase of the Robotaxi does it, it’s front page news and needs to be magnified.

He said:

“Look, I mean, drivers make mistakes all the time. Why should we hold Tesla to a standard where there can be no mistakes?”

It’s refreshing to hear Cramer speak logically about the Robotaxi fleet, as Tesla has taken every measure to ensure there are no mishaps. There are safety monitors in the passenger seat, and the area of travel is limited, confined to a small number of people.

Tesla is still improving and hopes to remove teleoperators and safety monitors slowly, as CEO Elon Musk said more freedom could be granted within one or two months.

Tesla already has nearly 12,000 Supercharger piles across mainland China. However, the company just initiated the rollout of the ultra-fast V4 Superchargers in China for the first time, bringing its quick-charging piles to the country for the first time since their launch last year.

The first batch of V4 Superchargers is now officially up and running in China, the company announced in a post on Chinese social media outlet Weibo today.

Tesla China teases arrival of V4 Superchargers in 2025

The company said in the post:

“The first batch of Tesla V4 Superchargers are online. Covering more service areas, high-speed charging is more convenient, and six-layer powerful protection such as rain and waterproof makes charging very safe. Simultaneously open to non-Tesla vehicles, and other brands of vehicles can also be charged. There are more than 70,000 Tesla Superchargers worldwide. The charging network layout covers 100% of the provincial capitals and municipalities in mainland China. More V4 Superchargers will be put into use across the country. Optimize the charging experience and improve energy replenishment efficiency. Tesla will accompany you to the mountains, rivers, lakes, and seas with pure electricity!”

Tesla has over 70,000 Superchargers worldwide. It is the most expansive and robust EV charging network in the world. It’s the main reason why so many companies have chosen to adopt Tesla’s charging connector in North America and Europe.

In China, some EVs can use Tesla Superchargers as well.

The V4 Supercharger is capable of charging vehicles at speeds of up to 325kW for vehicles in North America. This equates to over 1,000 miles per hour of charging.

Elon Musk hints at when Tesla could reduce Safety Monitors from Robotaxi

Tesla could be reducing Safety Monitors from Robotaxi within ‘a month or two,’ CEO Elon Musk says.

Elon Musk hinted at when Tesla could begin reducing Safety Monitors from its Robotaxis. Safety Monitors are Tesla employees who sit in the front passenger seat during the driverless rides, and are there to ensure safety for occupants during the earliest rides.

Tesla launched its Robotaxi fleet in Austin last Sunday, and after eight days, videos and reviews from those who have ridden in the driverless vehicles have shown that the suite is safe, accurate, and well coordinated. However, there have been a few hiccups, but nothing that has put anyone’s safety in danger.

A vast majority — close to all of the rides — at least according to those who have ridden in the Robotaxi, have been performed without any real need for human intervention. We reported on what was the first intervention last week, as a Safety Monitor had to step in and stop the vehicle in a strange interaction with a UPS truck.

The Tesla and UPS delivery truck were going for the same street parking space, and the Tesla began to turn into it. The UPS driver parallel parked into the spot, which was much smaller than his truck. It seemed to be more of an instance of human error instead of the Robotaxi making the wrong move. This is something that the driverless cars will have to deal with because humans are aggressive and sometimes make moves they should not.

The Safety Monitors have not been too active in the vehicles. After all, we’ve only seen that single instance of an intervention. There was also an issue with the sun, when the Tesla braked abnormally due to the glare, but this was an instance where the car handled the scenario and proceeded normally.

With the Robotaxi fleet operating impressively, some are wondering when Tesla will begin scaling back both the Safety Monitors and Teleoperators that it is using to ensure safety with these early rides.

CEO Elon Musk answered the inquiry by stating, “As soon as we feel it is safe to do so. Probably within a month or two.”

Musk’s response seems to confirm that there will be fewer Teleoperators and Safety Monitors in the coming months, but there will still be some within the fleet to ensure safety. Eventually, that number will get to zero.

Reaching a point where Tesla’s Robotaxi is driverless will be another significant milestone for the company and its path to fully autonomous ride-sharing.

Eventually, Tesla will roll out these capabilities to consumer-owned vehicles, offering them a path to generate revenue as their car operates autonomously and completes rides.

For now, Tesla is focusing on perfecting the area of Austin where it is currently offering driverless rides for just $4.20 to a small group of people.
