SpaceX has confirmed that bad weather and an unfortunate lack of hardware has caused the second-ever Falcon Heavy center core to slide off the deck of drone ship Of Course I Still Love You, although CEO Elon Musk suggests that the rocket’s engine section could be recoverable.

Despite the fact that all three Falcon Heavy Block 5 boosters did successfully land after the rocket’s commercial launch debut, the accidental post-landing loss of center core B1055 takes a bit of the wind out of the sails of the whole recovery endeavor. Preventable hardware destruction aside, this should not detract from the critical fact that side boosters B1052 and B1053 are safe and sound at SpaceX’s Cape Canaveral Landing Zone (LZ), and should still be able to support Falcon Heavy Flight 3 without delay. This anomaly also serves as a bit of an abrupt reminder of just how hard the safe landing and recovery of giant, orbital-class rocket boosters really are.

According to Musk, the loss of Falcon Heavy B1055 was caused by a combination of bad weather and the surprising fact that SpaceX’s robotic rocket grabber had yet to be modified to support Falcon Heavy center cores. Octagrabber is used to secure Falcon boosters after drone ship landings in order to better ensure the safety of SpaceX’s recovery crew. In anything short of quiet seas, massive, emptied Falcon boosters frequently end up sliding around the drone ship deck – ironically, one of the flight-proven side boosters that flew on Falcon Heavy’s launch debut was almost lost to (apparently) the same failure mode that has now effected B1055.

Musk suggested that the Falcon Heavy booster’s Merlin 1D engines could potentially be recovered and reused “pending inspection”, indicating that B1055 may still be partially sitting on OCISLY’s deck. A similar event happened during the 2016 launch of Eutelsat 117 West B, when a Falcon 9 booster aggressively impacted OCISLY’s deck after running out of propellant but left behind its battered octaweb. In B1055’s case, the booster was almost certainly safed, detanked, and depressurized, meaning that it probably didn’t explode when it tipped over and impacted the water and drone ship guardrail. SpaceX may even be able to recover the booster’s four valuable titanium grid fins and salvage additional hardware, depending on how much of the rocket remained intact and attached to OCISLY.

In December 2018, Falcon 9 B1050 suffered a grid fin hydraulic pump failure that caused the Block 5 booster to lose control authority. Despite the struggle, it managed a soft landing and SpaceX may even attempt to reuse the booster in the future.

The sad loss of another Falcon Heavy center booster has once again preventing SpaceX recovery engineers from being able to fully analyze the unique rocket’s custom side booster attachment and separation hardware. Still, the fact that major sections (including the entire octaweb) may be recoverable means that B1055 will at least be able to produce more valuable data than center core #1, which smashed into the Atlantic at ~300 mph after its 2018 debut.

A step further, the US Air Force recently indicated that Falcon Heavy Flight 3 – carrying its Space Test Program 2 (STP-2) rideshare mission – would reuse both of this launch’s side boosters but feature a brand new center core. This was announced well before B1055’s anomaly, indicating that SpaceX and the USAF had planned for some time to use new center cores on Falcon Heavy Flights 2 and 3. This means that B1055’s untimely demise should have little to no impact on SpaceX’s launch manifest, including the imminent STP-2 mission.

Falcon Heavy Flight 3 is currently scheduled to launch the USAF STP-2 mission no earlier than late June – a major customer with satellites aboard has suggested NET June 22. Of course, SpaceX has only had a handful of days with its recovered Block 5 side boosters, the refurbishment of which will now be the critical path for the next launch. If B1052 and B1053 are in exceptionally good shape, a distinct possibility thanks to their relatively gentle return-to-launch-site (RTLS) recoveries, then that late June date may very well hold.

Elon Musk and Trump are closer than ever, and Tesla could be the big winner

Elon Musk sat beside Trump as AI leaders signed a voluntary White House safety accord.

Published

Elon Musk had the seat right next to President Donald Trump on Tuesday as the White House hosted the leaders of America’s biggest artificial intelligence companies for a lunch that ended with a voluntary industry accord on AI safety.

A seating chart Trump posted on Truth Social placed Musk at the president’s left in the East Room, with Nvidia CEO Jensen Huang on his right, according to an Associated Press reporter. Anthropic CEO Dario Amodei, OpenAI President Greg Brockman, Meta’s Mark Zuckerberg, Google’s Sundar Pichai, Microsoft’s Satya Nadella and Amazon founder Jeff Bezos also attended, along with Vice President JD Vance and House Speaker Mike Johnson.

After the lunch, Trump told reporters outside the West Wing that the executives had signed “The White House Accord on Superintelligence: A Joint Commitment on Frontier SI Responsibilities.” Johnson described it as a voluntary statement of principles built on “robust internal controls and layers of internal and external review,” while Zuckerberg said company boards would independently review reports from outside auditors. Trump called the document “morally binding,” said he would name a new AI czar within days, and signed an executive order formally renaming artificial intelligence “super intelligence,” CNBC reported.

Musk was not in the room for Tesla alone. Since SpaceX absorbed xAI, he runs the company behind Grok and one of the largest AI training operations anywhere. On September 25, he said another 220,000 Nvidia GB300 chips would come online at Colossus 2 within a week, with more expected in November and December.

SpaceX confirms third massive compute deal at Colossus data center

 

Musk also used the trip to restate his energy ambitions. “SpaceX is aiming together with Tesla to do 200 gigawatts of solar production per year,” he said at an event in Washington. It is the same combined target he laid out that feeds directly into Terafab, the Tesla and SpaceX chip venture that will need enormous amounts of power.

The showing between Musk and Trump has come a long way, since the two had the very public split in mid 2025 after Musk opposed the “Big Beautiful Bill” and left DOGE. They reconciled at Charlie Kirk’s memorial that September, and Trump later called their relationship “good”. Since then, Musk has joined Trump’s China delegation in May and attended last week’s White House state dinner for Chinese President Xi Jinping.

For Tesla, that access to government official could pay dividends. As Teslarati noted in January, federal autonomy rules, NHTSA oversight and a single national standard for driverless vehicles all run through an administration Musk can more easily reach directly as Tesla works to scale Robotaxi and Cybercab beyond Texas.

Tesla Roadster’s new patent preps white-knuckle speeds, keeping it grounded

Published

Ahead of its highly anticipated unveiling, Tesla’s upcoming Roadster received a new patent that aims to keep it grounded while enabling white-knuckle speeds.

The patent, which was granted on September 29, is titled “Electric Car Fan,” bluntly stating its design but not its purpose, which is further detailed in the text of the application. Interestingly, it comes two weeks before the Roadster event, which was delayed due to unfavorable weather on Thursday, which could cause issues, as Tesla revealed the event must be held outdoors.

The purpose is to solve a problem that is relatively unique to high-performance electric cars. Instant motor torque is useless if the tires cannot plant that force, and conventional wings and underbody tunnels generate downforce only when air is already rushing past the car. At launch, in slow corners, and under hard braking from modest speed, passive aerodynamic additions contribute essentially very little to downforce.

Tesla’s filing says that its fans can produce the downforce needed, independent of vehicle velocity, then ease off so the same hardware does not pile on drag at highway speeds, an issue that can come from excessive body modifications.

The hardware outlined in the patent is a ducted-fan package that is placed into the rear of the vehicle. An underbody inlet between the rear wheels feeds a duct that rises to a wide outlet in the diffuser. In that outlet are four axial fans, which are divided by vertical strakes. They will pull air from under the floor and press the chassis onto the pavement.

The language in the patent claims it can cut drag rather than add to it while simultaneously increasing downforce.

Tesla Roadster event requires restricted airspace, and the FAA obliges

The fans run from the high-voltage battery and a vehicle control system, so output can be modulated rather than left on as a fixed penalty.

There are additional strengths that can come from this design, like extra tire load at low speed, which can contribute to even more face-melting acceleration rates, decrease stopping distance, and sharper turn-in before a wing has air to work with. Adjustable fan speed lets the car add grip only when needed, so it can be catered to the force of a turn or acceleration.

These designs were previously used, and banned, in some competitive settings. The Brabham BT46B was banned in F1 competition for using a similar fan design and being labeled as too effective.

Tesla still lists the Roadster as having a sub-two-second 0-60 MPH time and a 250-plus-MPH top speed, and there are expectations for a SpaceX cold-gas thruster package that could not only increase acceleration but potentially cause the vehicle to hover.

It is important to note that a patent is not a production part, and packaging four fans in a rear diffuser, managing noise, and potential debris are all things Tesla must consider. With that being said, the patent being granted shows Tesla is designing the Roadster to go fast, but it is also attempting to use unique strategies to combat any issues it might have at those speeds.

SpaceX turned a heralding moment for Starship into its greatest

Starship reached orbit despite losing an engine, deployed 26 Starlink V3 satellites on Flight 14.

SpaceX’s Starship reached orbit for the first time on Monday, and for a few nail-biting minutes it looked like it wouldn’t. During ascent on Flight 14, one of Ship 41’s six Raptor engines shut down early, and SpaceX’s livestream host Dan Huot told viewers the team had decided not to commit to orbit. Minutes later, after what Huot described as a lot of conversation in the control room, the final poll came back in favor, and a roughly 19 second burn of a single Raptor pushed the ship into orbit about 170 miles up.

The reversal matters because SpaceX had written the exit ramp into the mission plan. The company said it would only fire the orbital insertion burn if flight controllers confirmed enough backup hardware remained for the deorbit burn, a condition Teslarati laid out ahead of the flight. Losing an engine was exactly the scenario that rule was built for.

Pressing forward fits Elon Musk’s history. Falcon 1 failed three straight times before its fourth launch reached orbit in 2008, with SpaceX nearly out of money, and Starship was developed by flying prototypes until they broke. What changed this year SpaceX going public, and with $SPCX sliding below its IPO price in July when Flight 13 slipped, the short interest climbed significantly, as Teslarati reported at the time. A Starship potentially lost today with revenue generating next-gen Starlink satellites aboard would have landed directly on shareholders.

That pressure showed up after orbit. SpaceX cut a flight planned to last nearly 10 hours to about three, moving splashdown from west of Chile to the North Pacific near Hawaii. SpaceX gave no reason, though Musk said this month the company was being extremely cautious about debris risk. The single Raptor for deorbit worked, and Ship 41 completed its flip and landing burn before breaking apart in the water, an outcome SpaceX expected. Musk has structured SpaceX’s governance to shield long term bets from market pressure.

The payload is the bigger business story. Musk posted that all 26 Starlink V3 satellites deployed and are “operating nominally.” Each V3 is rated for about 1 Tbps of downlink and 160 Gbps of uplink, so this single launch adds roughly 26 Tbps, about 10 times what a Falcon 9 load of V2 Mini satellites adds. The V3 is too large for Falcon 9, making Starship the only vehicle that can build out the planned 100,000 satellite constellation, at up to 60 per flight once it reaches routine service. Unlike the 20 V3 units on Flight 13, which reentered on a suborbital path, these will raise their orbits and could begin serving customers within weeks and bring in hundreds of millions of additional dollars in projected Starlink revenue.

SpaceX has already begun winding down Falcon 9 Starlink launches from Florida in favor of Starship. Reported targets put Flight 15 as early as October 19, leaving about three weeks to diagnose Monday’s engine shutdown before the next orbital attempt.
