Following the Falcon 9 booster’s second successful NASA launch in less than three months, SpaceX recovery technicians have once again rapidly retracted B1056’s four landing legs, also reused from the booster’s May 2019 launch debut.

On the heels of Falcon 9 B1056’s first speedy, leg-retracting recovery, a repeat of the booster’s impressive landing leg retraction debut – using the same legs, no less – serves as an excellent sign that whatever hardware changes were implemented are on the right track. As part of SpaceX and CEO Elon Musk’s interim goal of launching the same Falcon 9 booster twice in 1-2 days, a speedy recovery is an absolute necessity, and landing leg retraction is just one of the dozens of ways the company will need to optimize recovery and reuse to lower average turnaround times from weeks to days.

Falcon 9 B1056 completed its successful launch debut on May 4th, 2019, landing on drone ship Of Course I Still Love You (OCISLY) to preserve an ongoing Crew Dragon failure investigation at Landing Zones 1 and 2 (LZ-1/2). Situated just a few dozen miles off the coast of Florida, OCISLY returned to port with the booster barely a day after the landing, easily the fastest drone ship return yet.

Less than two days after arriving at Port Canaveral, SpaceX technicians had already begun the landing leg retractions in what was the first actual attempt in months. Falcon 9 Block 5 debuted back in May 2018 with comments from Musk indicating that retractable legs were one of several major reusability-focused changes, but SpaceX recovery technicians never got beyond a handful of partial tests in the second half of 2018.

This ended with a truly flawless full retraction of all four landing legs on May 7th, confirmed when booster B1056 was flipped horizontally, loaded onto a powered transporter, and driven back to a SpaceX refurbishment facility with all four scorched legs installed.

Even more impressively, although it’s impossible to know if the retracted legs were removed, inspected, and reattached during refurbishment, all four of those legs were unambiguously flown again on B1056’s second launch less than three months later. Some cursory analysis of photos of CRS-18 taken by SpaceX, NASA, and others definitively identifies all four landing legs as the same ones that flew on CRS-17 – installed in the same positions, no less.

At least in the context of the Falcon family of rockets, SpaceX’s ultimate goal is to dramatically lower the cost of Falcon 9 and Heavy launches by quickly, easily, and safely reusing every part of the rocket except its orbital upper stage, which makes maybe 10-15% of hardware costs. A magnitude reduction in costs is thus out of the question for the Falcon family – a challenge that will be tackled instead by Starship and Super Heavy, a new clean-sheet launch vehicle.

Nevertheless, it’s entirely possible that Falcon 9 missions will be able to launch for 3-5 times less than their current list price ($62M) within a year or two and definitely before the family is replaced by its successor(s). In fact, according to CEO Elon Musk, SpaceX has already lowered the average base price nearly 20%, cutting it to $50M to communicate some of the financial rewards of efficient reuse to its customers.

Of course, it’s important to remember that even if SpaceX gets to a point where it could technically cut its launch prices in half (or more), breaking even on a marginal cost basis does not account for SpaceX’s desire to recoup some of the $1B+ it has spent perfecting Falcon reusability. The fact that prices have (at least according to Musk) been lowered a decent amount is a good sign that SpaceX will choose market expansion over greed, but one can never be certain and Falcon 9 and Heavy pricing may very well never reflect their true reusability.

For now, SpaceX’s rapid progress from zero landing leg retraction to retracting the same booster’s same four landing legs twice in less than three months is an excellent sign that Block 5’s capabilities continue to be refined. In terms of milestones, the first launch of a thrice-flown booster is up next for Falcon 9, as is the first reuse of a recovered Falcon fairing half (or two).

Tesla Cybercab and Robotaxi’s real advantage won’t be the ride service

Published

Concept art of a Tesla Cybercab in Las Vegas Strip as rendered via Grok

For a century, the car has asked the same thing of its owner, which is basically to pay attention. Even the best ride-hailing app like Uber or Lyft only moved the problem into someone else’s hands. You stopped driving, but you still sat in a stranger’s car, while half listening, and wondering whether to take a phone call in the car without being rude. The Cybercab has no wheel, no pedals and no driver. With Grok @bot now live inside it, it becomes something else entirely, and I think that matters more than the fleet count that everyone is tracking.

Grok @bot is an agent, not a voice assistant. A rider signs in once, and from then on can say what they need and watch it happen. Order dinner from a favorite restaurant. Fill the grocery cart. Move money, answer email, adjust a calendar, push a work project forward. Tesla engineer Yun-Ta Tsai confirmed it is enabled across every Cybercab and the rest of the Model Y fleet, and Tesla’s own pitch is that Full Self-Driving handles the commute while Grok handles the errands.

Think about what that does to a thirty minute ride. Uber sells you a trip, while Waymo sells you the same trip in a more private setting. Tesla is selling the thirty minutes themselves, returned to you with an assistant attached. Errands that used to eat a Saturday get done between pickup and drop off. The ride stops being dead time between two places and becomes a place of its own.

Tesla integrates Grok Bot into its vehicles for the ultimate personal assistant

Best of all, your Bots follow you into any Cybercab, and presumably your own Tesla, then logs you out automatically when you step out. Anyone can bolt a chatbot onto a screen, but much harder to own the vehicle, the autonomy stack and the assistant at once. It also quietly ties SpaceX’s Super Intelligence business to Tesla’s fleet, after Tesla converted its xAI stake into SpaceX equity. The relationship between those two companies is getting harder to describe as separate.

This is also where the hard questions start, because an agent that can spend your money in a vehicle other people also ride in needs some answers. How does it handle a voice it shouldn’t trust? What gets recorded, who can see it, and for how long? What happens when a rider leaves halfway through a task?

If Tesla gets those answers right, the scoreboard changes. We have been counting Cybercabs and wait times. The more telling number may be what riders accomplish per trip. That is data almost no one else will ever have, and it is the real reason to watch Grok @bot.

What do you think? Leave me a comment.

Why Elon Musk’s target date for buying an Optimus robot is harder than it sounds

Musk says China’s magnet export ban cost Optimus months, and robot hands remain shockingly hard.

Elon Musk says China’s export curbs on magnets used in electric motors set back Tesla’s Optimus program by two to three months, and that the robot’s hands remain the hardest part of the project. He made the comments Saturday during a live interview with Tesla Owners Silicon Valley at the X Takeover event at Giga Texas, in front of roughly 2,000 attendees. The Optimus discussion begins around the 49 minute mark of the stream.

On the hands, Musk was blunt and noted that a general purpose humanoid needs fine motor skills that are “incredibly difficult to get right. Shockingly difficult,” he said in the interview. He pointed to a problem he says no one has demonstrated yet: “One of the hardest things also generally is to do precision and force at the same time,” such as driving a small self tapping screw into wood. Touch sensors add another layer, since it is “actually kind of hard to get touch sensors that elastically deform and can handle high cycle life and it won’t just break after a few thousand cycles.”

He also took aim at rival robot videos. “Any complicated looking robot demo, it’s a canned demo. It’s not real,” Musk said, adding that real AI means showing a robot something it has never seen and watching it still cope, the way FSD handles a city it has never driven.

Musk expects the Optimus ramp to be slower than a new vehicle production ramp. “The initial part of that S curve of production ramp is going to be very slow at the beginning,” Musk said, partly because “unlike cars, there’s no pre existing supply chain for robot stuff.” That echoes his July reply on X that Optimus production “will be extremely slow at first, as everything is new.”

The magnet disclosure puts a number on a problem Musk first raised in 2025. He said China “prevented the export of magnets for use in electric motors” and that it “set back the Optimus program by like two or three months.” Then he added: “We had robots with no arms.” Tesla’s fix is to bring the supply chain home. “You’ve got to be able to make all the parts domestically,” he said. Teslarati reported in April 2025 that Musk tied the issue to permanent magnets in the arm actuators, where motors have to be as small as possible.

Production is moving regardless, with a reported internal goal of more than 1,000 a week by the end of 2026. Teslarati recently covered how Tesla is certifying supply partners in China for Optimus parts, while the company’s hand design has been the subject of new patent filings.

Musk has said he wants Optimus available to the public by late 2027, though Tesla has not confirmed that date or published updated production figures.

Elon Musk drops a Thanksgiving hint about Starship’s biggest test yet

Elon Musk says Starship Flight 15 will try to catch the ship itself, a first.

Elon Musk says SpaceX’s next Starship flight will try something nobody has done before, by catching the ship itself. Speaking to roughly 2,000 people at the X Takeover event at Giga Texas on Saturday, Musk said Flight 15 is about four to six weeks away and “probably launches a little bit before Thanksgiving, is my guess.”

That is a slip from earlier reporting, which had pointed to a launch as early as October 19. Musk explained why the date keeps moving. “We’re making a bunch of improvements to the rocket between every flight,” he said, adding that there are often hundreds, sometimes thousands, of small changes. This time the list is short, “but some of them take a fair bit of work and we’ve got to go inside the tank to make some of these changes.”

“We’re going to try to catch the ship, which is a super big deal,” Musk said. “If we do so, that’ll be the first time that there’s been full recovery of an orbital class rocket.” SpaceX has already caught the Super Heavy booster with the tower’s mechanical arms, and has talked about catching the ship since late 2025, but the upper stage has never been caught.

Musk also laid out what comes after. “The next big milestone would be to refly both the booster and the ship,” he said, describing a Flight 16 where “all parts of an orbital rocket are reflown.”

The reason SpaceX wants this comes down to cost and cadence. Every Starship ship so far has ended its flight in the ocean, and SpaceX expects most of those water landings to end in fireballs. A ship that returns to Starbase intact can be inspected and flown again. SpaceX’s IPO filing, says Starship V3 is designed to deliver 100 metric tons to orbit in a fully reusable configuration, that SpaceX aims to cut the cost to reach orbit by 99% or more versus the historical average, and that tower catches should allow “multiple launches per day.”

The payoff goes beyond cheaper launches. The next generation Starlink V3 satellites are too large for Falcon 9 and can only fly on Starship, which can carry up to 60 per flight. Flight 14 on September 28 deployed the first 26 of them after Starship reached orbit despite an early engine shutdown, as Teslarati reported. Musk blamed engine computer software, and said the heat shield “was extremely robust,” which he claimed in August had solved Starship’s biggest challenge.

NASA’s Moon plans depend on the same capability. NASA’s inspector general has described a lander mission that needs a propellant depot in low Earth orbit and more than 10 tanker flights, with SpaceX targeting one tanker launch every six days. That schedule only works if ships and boosters come back fast and fly again. Also, ship to ship propellant transfer has not been attempted yet.

One interesting hurdle yet to be explored is bringing the ship back to the launch site, with reentry over land, which will undoubtedly come with a lot of aviation safety reviews.
