SpaceX to launch one of its last old-gen Falcon 9s in upcoming launch
One of SpaceX’s rapidly shrinking fleet of older Falcon 9 launch vehicles has rolled out to the company’s California launch pad ahead of an expendable launch and fairing recovery attempt scheduled for no earlier than Tuesday (NET) 12:47 pm PST/19:47 UTC May 22.
Although SpaceX may have inaugurated a new era of truly reusable rocketry with the debut of Falcon 9 Block 5 earlier this month, there are still a number of older Falcon 9 boosters (all flight-proven) awaiting their second and final flights. At the moment, a minimum of four cores remain, including the sooty Falcon 9 first stage captured earlier this evening by Teslarati photographer Pauline Acalin.
Foreshadowing its imminent watery demise with a lack of landing legs, this particular booster (B1043) previously launched the mysterious and controversial Zuma mission in January 2018, a classified payload claimed (sans convincing evidence) to have failed and reentered Earth’s atmosphere mere hours after reaching orbit. While it’s possible that the mission was a failure, at the moment unsteadily blamed on the failure of a Northrop Grumman-designed payload adapter and deployment mechanism, it’s far more probable that the apparently wildly-expensive satellite is still in orbit.

Checking the pulse of Earth’s gravity
Regardless, the same SpaceX rocket booster responsible for lifting Zuma and the Falcon 9 upper stage out of the atmosphere is now ready to launch a new payload at SLC-4E, a launch pad stationed in Vandenberg Air Force Base. B1043’s second orbit-destined payload is a compliment of seven satellites: five are of the Iridium NEXT variety and the remaining satellites make up a scientific mission and technology demonstrator known as GRACE-FO (FO for Follow-On).

Following in the footsteps of the original GRACE’s (Gravity Recovery and Climate Experiment) 15 year orbital tenure, GRACE-FO is effectively the same mission with significantly upgraded hardware – the biggest experimental component is actually an advanced laser interferometer designed to measure the distance between the two satellites (roughly equivalent to the distance between LA and San Diego) with the precision of a single micrometer (10-100x smaller than the width of a human hair). At that level of precision, the pair of satellites can detect minute changes in Earth’s gravity, to the extent that they can actually observe droughts, floods, and ice melt through the change in gravity caused by the movement of large (i.e. heavy) quantities of water. If the experimental laser ranging technology works as intended, it will be at least ten times more accurate than the microwave-ranging technology also installed on the follow-on satellites.
SpaceX’s rocket fleet makes way for Block 5
On the SpaceX side of things, Falcon 9 B1043 will be expended after dutifully completing the launch of Iridium-6/GRACE-FO, although the presence of grid fins on the rocket indicates that SpaceX will likely continue a regime of soft-landing recovery tests to optimize and flesh out the limits of Falcon 9’s capabilities. At first glance, the tradeoff of expending entire rocket boosters able to be (relatively inefficiently) refurbished for considerably more than two flights seems extreme and inadvisable. However, SpaceX is presumably ravenous for data on the survivable envelope of Falcon 9 performance – particularly reuse – in advance of the complete transition to the rocket’s Block 5 iteration, a significant upgrade likely to come hand in hand with a more pronounced aversion to expendable missions given each booster’s design lifespan of 10 to 100 missions. At that level of reusability, expending Falcon 9 Block 5s would truly become comparable with the absurdity of trashing an airliner after one or a handful of flights, an (in)famous talking point used by Elon Musk over his years of public SpaceX discussions.

Thus, if SpaceX can gather data that might enable future Falcon 9 Block 5 recoveries by expending much less valuable Block 3 and 4 boosters, the payoff would be irresistible once examined with a long-term outlook. In the sense that Block 5 may be capable of magnitudes more flights with considerably cheaper refurbishment, the literal elemental value of the hardware – in the likely event that Block 5 production is more capital-intensive than Block 3/4 – is more or less irrelevant for an aversion to expending Block 5 boosters.
Rather, what is lost alongside an expendable Block 5 mission is instead the comparatively vast amount of revenue locked within dozens of additional highly-profitable launches each expended booster could have supported. From that perspective, expending Block 3s and 4s to gather data might be accurately compared to destroying single-pilot Cessnas to improve the utility of a 747 airliner.
After B1043 is expended, only three obvious flightworthy cores will remain outside of the gradually growing Falcon 9 Block 5 fleet (just two boosters, currently). In order of anticipated launch, these three missions are SES-12 (NET May 31), CRS-15 (NET June 28), and the Crew Dragon in-flight abort test (NET Q4 2018). Barring the unexpected refurbishment of an older flight-proven core for a third mission, these final three missions will bring to a close the inherently temporary era of partially-reusable SpaceX rockets – in the words of Elon Musk, Block 5 would thus signify that SpaceX has moved from “the dog that caught the bus” to, perhaps, the dog that caught the bus and then learned how to drive and maintain it. Somewhere in the middle of those final throes of old-guard Falcons will be an ever-increasing cadence of Block 5 launches and re-launches, likely including the first manifest-necessitated reuse of a Block 5 booster sometime this summer.

Meanwhile, despite the sealed fate of the rocket’s booster, tomorrow’s launch will debut fairing-catcher Mr Steven’s new and improved net. With the introduction of an upgraded net and what can only be described as back-to-back days of relentless ocean-going practice over the last two weeks, it’s entirely possible that Iridium-6/GRACE-FO will be able to lay claim to the first successful catch of a payload fairing following an orbital rocket launch. Fingers crossed.

Elon Musk’s Boring Company lands a new Middle East deal, and Nashville is about to get faster
The Boring Company signs Abu Dhabi tunnel agreement while adding more Prufrock machines in Nashville.
The Boring Company has signed an agreement with Abu Dhabi to study underground transport and utility tunnels across the emirate, adding a second UAE city to its pipeline as it prepares to also scale up tunneling back home in Nashville.
The deal was signed Thursday at the Liveability and Investment Exhibition (LIVEX 2026) by Boring Company President Steve Davis and Maysarah Mahmoud Salim Eid, director general of the Abu Dhabi Projects and Infrastructure Centre (ADPIC), according to the Abu Dhabi Media Office. Mohamed Ali Al Shorafa, chairman of the emirate’s Department of Municipalities and Transport, attended the signing.
Under the agreement, the two sides will assess feasibility, delivery and operating models for tunnels that could carry passengers or utilities. They will also look at Abu Dhabi’s potential as a regional hub for tunneling work. The current phase is exploratory, and no construction commitment or project budget has been announced.
“Abu Dhabi provides an ideal environment to explore the next generation of underground infrastructure solutions, supported by its ambitious growth vision and strong commitment to advanced technologies,”
Davis said. He added that the company wants to assess how tunnels can “expand urban capacity more efficiently, and enable better use of available space.”
The timing lines up with the money, considering last month, The Boring Company closed a $3 billion Series D led by the UAE and affiliated investors, valuing the company at $23 billion, as Teslarati reported. That round came with a commitment to build more than 150 kilometers of tunnel across the UAE, separate from the Dubai Loop pilot already under contract with Dubai’s Roads and Transport Authority. That pilot covers 6.4 kilometers and four stations linking DIFC and Dubai Mall at a cost of about $154 million.
Back home, The Boring Company projects in Nashville are also scaling up, with the company telling local NewsChannel 5 that a third Prufrock machine could start digging the Music City Loop in late October. A fourth is also targeted before the end of the year. Two machines are already mining Nashville limestone at the same time, and work is underway on a new launch site for the third.
The company said it has made more than 300 design and performance upgrades to its original Nashville machine. It is also working with property owners on more than 40 planned stations, with approvals in place for a future Nashville International Airport connection, a downtown station near the Music City Center, and stops at residential towers and the JW Marriott.
Construction on the Music City Loop began the same evening Tennessee and federal regulators approved the project’s lease in February, and the company targeted its first operational segment for late 2026. Back in Las Vegas, The Boring Company has said it plans to double its Vegas Loop station count by year’s end.

SpaceX brings four astronauts home after 8 months in space, and the return was flawless
SpaceX Crew Dragon Freedom returned four Crew-12 astronauts home after 237 days aboard the station.
Four Crew-12 members are back on Earth after 237 days at the International Space Station. SpaceX’s Crew Dragon Freedom splashed down in the Pacific Ocean about 50 miles west of Los Angeles at 11:34 a.m. ET on Thursday.
NASA astronauts Jessica Meir and Jack Hathaway, ESA astronaut Sophie Adenot, and Roscosmos cosmonaut Andrey Fedyaev landed one day after undocking from the station’s Harmony module at 8:05 a.m. ET on Wednesday. NASA confirmed the splashdown minutes later. SpaceX had flagged the 27.5 hour trip home on X while Dragon was still firing its departure burns away from the station.
The descent ran on schedule when Freedom started a nine minute deorbit burn at 10:46 a.m. ET, then hit the thicker atmosphere about 36 minutes later at nearly five miles per second. Chutes deployed at around 18,000 feet, and four main parachutes brought the capsule down to roughly 15 mph at splashdown.
SpaceX fast boats secured Dragon before the recovery ship Shannon hoisted it onto the deck with the crew still inside. Flight surgeons on board ran initial medical checks. All four crew members will be flown ashore by helicopter and then head to NASA’s Johnson Space Center in Houston for rehabilitation.

Crew-12 launched on February 13 from Space Launch Complex 40 at Cape Canaveral, a flight that also marked the first Falcon 9 booster landing at SpaceX’s new LZ-40 pad. Over the mission, the crew completed 3,792 orbits, covered nearly 101 million miles, and carried out four spacewalks to maintain and upgrade the station.
Meir now has 440 cumulative days in space, which places her in NASA’s top 10. This was the first spaceflight for Hathaway and for Adenot, a French Air Force colonel and former helicopter pilot. Fedyaev, who spent 186 days in orbit on Crew-6 in 2023, has now flown two long duration Dragon missions.
The return closes out a busy stretch of Dragon traffic. Crew-13 arrived on October 1 aboard Crew Dragon Grace, which docked just 7 hours and 55 minutes after liftoff, the fastest launch to docking of any U.S. spacecraft in ISS history. Commander Jessica Watkins, pilot Luke Delaney, Canadian Space Agency astronaut Joshua Kutryk, and cosmonaut Sergey Teteryatnikov remain aboard alongside the three person Soyuz MS-29 crew.
With Crew-12 gone, the port is clear for CRS-35, a cargo Dragon carrying the final pair of ISS Roll-Out Solar Arrays. NASA is holding a post-splashdown teleconference at 1:15 p.m. ET covering both the crew’s return and the upcoming cargo launch.

Elon Musk shuts down talk of TSMC taking over Terafab
Musk says Tesla and SpaceX will build and run Terafab, with TSMC limited to renting.
Elon Musk has drawn a firm line around who will be in charge of Terafab, the giant chip factory Tesla and SpaceX are planning in Texas.
Musk replied to a post on X arguing that Taiwan Semiconductor Manufacturing Company (TSMC) would most likely end up owning and operating the plant. “No, we will build and run the fab. Let there be ZERO doubt about that,” Musk wrote. “Maybe TSMC subleases part of the Terafab if they want, but nothing more than that.”
In plain terms, a sublease means TSMC could rent a section of the complex to make chips, similar to a tenant renting one floor of an office tower. The building, the equipment decisions and the daily operation would stay with Tesla and SpaceX.
@herbertong @thejefflutz No, we will build and run the fab. Let there be ZERO doubt about that.
Maybe TSMC subleases part of the Terafab if they want, but nothing more than that.
— Elon Musk (@elonmusk) October 7, 2026
The comment shuts down speculation that started last week. On October 2, tech journalist Tim Culpan reported that TSMC was exploring ways to help run Terafab’s factories. Musk responded the next day that it was “just discussions, but something may come of it,” as Teslarati reported at the time. That left room for a scenario where the world’s largest contract chipmaker took the wheel. Musk’s latest post closes that door.
Some background helps explain why this matters. Tesla designs its own AI chips today but pays outside companies like TSMC and Samsung to manufacture them. Musk unveiled Terafab in March as a joint project between Tesla, SpaceX and xAI, arguing that existing suppliers cannot expand fast enough to meet his companies’ future demand. The goal is to produce enough chips each year to supply one terawatt of computing power, roughly 50 times what the entire global AI chip industry produces now.
Those chips are meant for Tesla’s Optimus humanoid robots, the Cybercab and Full Self-Driving computers, along with chips for SpaceX’s planned data centers in orbit. Owning the factory means Musk’s companies would not have to compete with every other chip customer for time on someone else’s production lines.
Intel is still part of the picture. The company signed on in April to help design, build and package chips for the project, and CEO Lip-Bu Tan told Bloomberg this week that Intel will keep working on Terafab despite the TSMC chatter.
The project moved from concept to construction planning over the summer. In August, SpaceX confirmed the Grimes County site about an hour from Houston, sent the county a $10 million payment under its tax abatement deal and said civil work would begin shortly. The first phase carries a $16.8 billion price tag, and total spending across all phases could reach as much as $119 billion.
TSMC chairman C.C. Wei has said a new fab typically takes two to three years to build and another one to two years to reach full output. Tesla and SpaceX have never run one, which is why TSMC’s expertise drew so much attention. Musk’s answer suggests he would rather learn that process in house than hand control of a project this central to Tesla’s robotics and autonomy plans to an outside company.
Terafab Texas will be the largest and most valuable building on Earth by far.
And it will be stunningly beautiful. https://t.co/4NweOqTL7y
