SpaceX’s next Falcon Heavy launch may feature record-breaking center core landing
Thanks to a temporary reopening of the US federal government, SpaceX was finally able to continue the process of filing FCC and FAA paperwork needed to acquire permits for upcoming launches, including Falcon Heavy.
One such filing related to the first operational Falcon Heavy launch has revealed a fairly impressive statistic: comprised of three first stage boosters, SpaceX indicated that Falcon Heavy’s center core will attempt to land on drone ship Of Course I Still Love You (OCISLY) nearly 1000 km (600 mi) away from its launch site, easily smashing the record for the greatest distance traveled by a Falcon booster in flight.
Of Course I Still Love You will be positioned a record ~965km downrange. That's nearly 300km further that the previous greatest distance of 681km, set during the Eutelsat-117WB mission in June 2016. (The landing was a failure, with the booster running out of LOX!) https://t.co/RECKjMtd37

The same FCC filings also revealed a No Earlier Than (NET) launch date: March 7, 2019. Originally targeted for mid to late February, the complexity and logistical challenges of building, shipping, testing, and delivering two side boosters, a center core, one upper stage, and a payload fairing from SpaceX’s California factory to its Texas test facilities and Florida launch pad unsurprisingly took a small toll on the launch’s aspirational schedule. Nevertheless, if the launch data actually holds to March 7th, SpaceX will not have missed the mark by much considering that this Falcon Heavy – based on new and more powerful Block 5 boosters – is likely a significant departure from the Block 2/Block 3 hardware that has flight heritage from the triple-booster rocket’s Feb. 2018 launch debut.

Just shy of a year after Falcon Heavy’s launch debut, it appears that the rocket’s second and third launches were pushed back by a fundamental lack of production capacity. In other words, SpaceX’s Hawthorne rocket factory simply had to focus on more critical priorities in the 6-9 months that followed the demo mission. At nearly the same time as Falcon Heavy was lifting off for the first time, SpaceX’s world-class production crew was in the midst of manufacturing the first upgraded Falcon 9 Block 5 booster (B1046) and wrapped up final checkouts just 10 days after Heavy’s Feb. 6 launch debut, sending the pathfinder rocket to McGregor, Texas for the first static fire of a Block 5 booster.
In the meantime, SpaceX’s decision to intentionally expend otherwise recoverable reused Falcon boosters after their second launches meant that the company’s fleet of flightworthy rockets was rapidly approaching zero, a move CEO Elon Musk specifically indicated was meant to make room for Block 5, the future (and final form) of the Falcon family. SpaceX’s busy 2018 launch manifest and multiple critical missions for the US government were thus balanced on the success, reliability, and rapid production of a serious number of Merlin engines, boosters, and upper stages. This included B1051 – the first explicitly crew-rated Falcon 9 – and B1054, the first SpaceX rocket rated to launch high-value US military (specifically Air Force) satellites. However, SpaceX also needed to produce a cadre of Falcon 9 boosters capable of easy reuse to support the dozen or so other commercial launches on the manifest.

That gamble ultimately paid off, with Block 5 performing admirably and supporting a reasonable – if not record-breaking – rate of reuse. SpaceX successfully launched B1054 for the USAF, completed B1051 (now at Pad 39A awaiting NASA’s go-ahead), and built enough reusable Block 5 boosters to support nine additional commercial missions in 2018. In hindsight, barring an assumption of a truly miraculous and unprecedented Falcon booster production rate, Falcon Heavy’s next launches were almost guaranteed to occur no fewer than 6-12 months after the rocket’s launch debut – SpaceX’s entire launch business depended on building 5+ unrelated Falcon 9 boosters, while Falcon Heavy customers Arabsat and the USAF were unlikely to be swayed to launch on flight-proven hardware so early into Block 5’s career.

All cylinders firing
Once Falcon 9 B1054 departed SpaceX’s Hawthorne factory (see above) in early October, it appears that the company’s production team pivoted directly to integrating and shipping the next three (or more) Falcon Heavy boosters back to back for the rocket’s second and third launches. The first new side booster departed the factory in mid-November, followed by a second side booster in early December and a (presumed but highly likely) center core at the turn of 2019. Both side boosters have been static-fired in Texas and are now at SpaceX’s Florida facilities, while the center core either just completed its Texas static fire testing or is already on its way East.

Once the center core and upper stage make their way to SpaceX’s Kennedy Space Center Pad 39A, the company’s technicians and engineers will be able to integrate the second Falcon Heavy to have ever existed in preparation for a critical static fire test. That could occur as early as February, although the launch debut of Crew Dragon (DM-1) – now NET March from Pad 39A after a relentless string of slips – will likely take precedence over Falcon Heavy and could thus directly interfere with its launch, as the launch pad and transporter/erector (T/E) has to undergo at least a few days of modifications to switch between Falcon 9 and Heavy.
Regardless, the next two Falcon Heavy launches will be well worth the wait. SpaceX’s FCC filings indicate that the center core may travel nearly 1000 km (600 mi) East of Pad 39A to land on drone ship OCISLY after launch, smashing the previous record attempt – during the June 2016 launch of Eutelsat 117WB – of ~700 km (430 mi). That Falcon 9 booster – albeit a less-powerful Block 2 variant – was unsuccessful in its landing attempt, running out of oxidizer seconds before landing. Falcon Heavy’s debut center core also happened to suffer a wholly different but no less fatal anomaly during landing, causing it to miss the drone ship and slam into the Atlantic Ocean at almost half the speed of sound (300 mph/480 km/h).

Known for their rocket performance estimates, NASASpaceflight forum user “Orbiter” first pointed out the impressive distance – gathered by mapping coordinates included in SpaceX’s Jan. 28th FCC filing – and estimated that the Falcon Heavy center booster flying a trajectory as implied could be traveling as fast as ~3.5 km/s (2.2 mi/s) at main engine cut-off (MECO), the point at which the booster separates from the upper stage and fairing. This would be a nearly unprecedented velocity for any Falcon booster, let alone a booster with plans to land after launch. Falcon 9 MECO typically occurs at velocities between 1.5 and 2.5 km/s for recoverable missions, while even the recent expendable GPS III launch saw F9 S1’s engines cut off around 2.7 km/s.
Whether that MECO velocity estimate is correct, Falcon Heavy’s NET March launch of the ~6000 kg (13,300 lb) Arabsat 6A satellite is likely to be an exceptionally hot reentry and recovery for the center core, while the rocket’s duo of side boosters will attempt a repeat of the debut mission’s spectacular double-landing at LZ-1.

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

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.
Tesla Optimus V3 hand and arm details revealed in new patents
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.
