Follow a SpaceX Falcon 9 Block 5 booster recovery from start to finish [video]
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.

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.
Good observations by @USLaunchReport. The lifting cap was stripped of the leg retraction hardware, so SpaceX is presumably changing the design of the retraction system.https://t.co/WRwLNbLKqF

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 shows what Roadster drivers will see on screen before thruster activation
Tesla’s Roadster video reveals a fighter jet inspired cockpit with a 5,500 PSI thruster gauge.
Tesla has given future owners their clearest look yet at the cockpit of its next generation Roadster. In a 34 second video posted to X on Friday afternoon, the company walked through the car’s touchscreen with a caption: “Inspired by fighter jet cockpits, Roadster’s interface was designed around the pilot.”
The clip opens on a black screen with red graphics and a 3D wireframe of the car, which sits beside the Roadster’s squared off yoke. Tapping parts of the model brings up controls for the rear wing, including low drag and high downforce positions, along with a charging page with a charge limit bar and a small music player. A row of tabs along the bottom reads Home, Vehicle, Listen, Climate and Navigate.
Most of the video is spent in Track Mode. The dashboard shows a live circuit map, a list of session lap times, brake and motor temperatures, and pressure and temperature readouts for each tire. A setup page lets the driver pick Auto, Low Drag, High Downforce or Custom aero modes, adjust aero balance and brake balance, and switch stability and traction control off. Along the bottom, a status bar reads “Thruster · 5,500 PSI” next to a “Boost Ready” indicator.
That gauge ties the software to the hardware Tesla showed off near Waco, Texas on October 15. The Thrust and Rocket versions use cold gas thrusters fed by carbon overwrapped pressure vessels, and Tesla lists 0 to 60 mph times of under 0.9 seconds and under 0.59 seconds for them, as Teslarati detailed in its breakdown of the three Roadster configurations. The base Performance car relies on a fan and ground sealing system for grip, and the aero settings on screen match the active wings and suction setup covered in our look at how the Roadster generates downforce.
The Roadster layout is a departure from the rest of Tesla’s lineup. Instead of a map centered screen, the Roadster puts the car itself at the center of the home page, and Tesla’s Roadster page lists two smaller forward displays alongside the main touchscreen. Tesla has not said whether any of the Track Mode telemetry will make its way to the Model 3 Performance or other vehicles.
The interface could still change before deliveries. Elon Musk said at the event that Roadster production will begin in 2028, and Tesla says the flagship Rocket version is not approved for public road use. Reservations are open with a $50,000 payment, while Thrust is listed as a limited release and Rocket is invite only.
Those who want to see the car in person will get their first chance this weekend. The Roadster goes on display in the lobby of the Petersen Automotive Museum in Los Angeles from October 24 to 27, according to Sawyer Merritt, the first time the public will be able to view it up close.

Tesla reveals Optimus Academy, where robots teach themselves
Tesla has begun building production quality Optimus robots in Fremont and revealed its training plan.
Tesla has started building Optimus on the high volume line it set up inside its Fremont factory, and the company says the robots coming off it are the first that meet the bar for a real product. “The bots coming off this line are the first production-quality bots that we have manufactured,” Tesla wrote in its third quarter shareholder letter, adding that it has “proven that the current manufacturing process for Optimus is suitable for a commercial product.”
The line sits in space that built the Model S and Model X until this spring. Tesla cleared the old vehicle line in 46 days, as Teslarati reported in July, to make room for robot production sized for one million units a year. On Wednesday’s earnings call, Elon Musk said most of the equipment for that capacity is already in Fremont, with output set to climb toward roughly 20,000 robots a week as the line ramps.
Musk described the ramp as a classic S curve. “The growth of Optimus is an S curve, but the initial curve is a shallow slope,” he said. The team is now refining the robot’s AI, electromechanical design, reliability and service life, and Musk expects that work to be finished by the end of next year, when Tesla plans to start delivering Optimus to outside companies for dangerous, repetitive and around the clock jobs.
The most interesting part of the call was how Tesla plans to teach the robots. Its cars send real driving data back to the AI team from millions of vehicles, but Optimus has no fleet like that yet. “A big difference with Optimus versus the cars is we don’t have this vast fleet of cars from which we can gather training data,” Musk said. Tesla’s answer is an Optimus Academy, where 10,000 to 20,000 robots will practice a wide range of tasks and feed what they learn into the next version of the model. Every unit off the Fremont line becomes a source of that training data.
Smarter hardware is on the way too. Tesla plans to put its AI5 chip into Optimus next year, and Musk said a new Optimus video should arrive within one or two months showing the robot completing tasks driven by AI rather than preprogrammed motions. He took aim at rival humanoid demos that only run scripted routines, saying those would not hold up in the real world.
The supply chain is lining up behind the program. In September, Tesla certified Tuopu, Joyson and Sanhua as mass production partners for Optimus components. A far larger Optimus factory is also rising at Giga Texas, where drone footage from Joe Tegtmeyer showed the steel frame nearing completion, and Musk has pegged that plant’s long term target at 10 million robots a year.
Tesla executives also said Optimus production costs are trending toward the expected manufacturing cost of Cybercab, a sign the robot is being engineered for volume from the start. The hands remain the toughest piece of the design, a point Musk also made at the X Takeover event earlier this month, as Teslarati covered at the time, and that is where much of the current engineering effort is focused.

The Starship moon landing number NASA and Elon Musk can’t agree on
Musk disputes NASA estimate of 22 Starship launches for Moon landing, predicting 6 to 8.
Elon Musk is disputing a new NASA safety panel estimate of how many Starship launches it will take to put astronauts on the Moon, saying the real number will be less than half the panel’s figure.
On Thursday, NASA’s Aerospace Safety Advisory Panel held its quarterly public meeting. Panel member Charlie Precourt, a former NASA astronaut, flagged the fueling process for SpaceX’s lunar lander as a major risk for Artemis IV, the mission planned to land a crew on the Moon in 2028. “We need to keep our eyes on numerous required fuelings for the lander,” Precourt said, according to Ars Technica. “I think the last estimate is around 22 flights.”
Ars Technica’s Eric Berger posted the comment on X, and Musk replied. “That’s way too high,” Musk wrote. “Actual number will be more like 6 to 8.”
The disagreement comes down to a basic problem with sending a ship as large as Starship to the Moon. Starship burns nearly all of its propellant just reaching Earth orbit, so it cannot continue on to the Moon without stopping for a refill. SpaceX’s answer is a gas station in space. First, a Starship that works as a storage tank, called a depot, is launched into orbit. Then a series of tanker Starships launch one at a time, dock with the depot and pump their leftover propellant into it. Once the depot is full, the lunar lander version of Starship launches, docks, fills up and heads for the Moon.
Every tanker trip is its own full rocket launch, which is why the count matters. More launches mean more time, more cost and more chances for something to go wrong before astronauts ever leave Earth. Berger estimated that even if SpaceX reaches twice weekly Starship launches by the end of 2027, filling a depot at the panel’s number would still take roughly three months.
How many tankers are needed depends mostly on how much propellant each one can carry to orbit and how much is lost along the way. Starship’s fuel and oxygen are stored at extremely cold temperatures, and some of it slowly boils off while waiting in orbit. More is lost in each transfer. NASA appears to be working from what Starship can lift today, while Musk’s range assumes a more capable rocket.
Musk has pushed back on higher counts before. In 2021, after a government document suggested 16 launches, he called that “extremely unlikely” and said eight tankers would be the most required.
Much of the answer depends on hardware SpaceX has not finished flying. As Teslarati noted earlier this year, the company plans to carry out the refueling process with its upgraded V3 Starship, and Precourt described Artemis IV as carrying “a large number of firsts.” He also praised NASA Administrator Jared Isaacman’s team for working to clear obstacles for both SpaceX and Blue Origin, whose Blue Moon lander does not rely on orbital refueling for its first mission.
