SpaceX Falcon 9 rocket lands for the last time ahead of risky in-flight abort test
SpaceX’s latest successful launch and landing has wrapped up with Israeli Moon lander Beresheet on its way to Earth’s neighbor, Indonesian communications satellite PSN-6 headed to its final orbit, and the second thrice-flown Falcon 9 Block 5 booster safely returned to Port Canaveral aboard drone ship Of Course I Still Love You (OCISLY).
Known as Falcon 9 B1048, its third successful landing and recovery will almost certainly be this booster’s last after its fourth launch was officially assigned to a critical Crew Dragon launch abort test, one that the booster is very unlikely to survive. According to SpaceX CEO Elon Musk, that test could occur as early as April and will push the first flight-proven Crew Dragon space capsule to its limits.

After weathering what Musk also described as the toughest reentry and heating conditions yet experience by a Falcon 9 booster meant for recovery, Falcon 9 B1048 landing (almost) flawlessly aboard drone ship OCISLY, stationed roughly 700 km (430 mi) off the Florida coast. Hinted at by the booster’s very slight lean on the recovery vessel’s deck, B1048 most likely cut thrust (or ran out of fuel) just before the optimal stop point, causing the rocket to fall a few unintended feet onto OCISLY and eat into part of the aluminum honeycomb ‘crush-core’ present on all Falcon landing legs.

In essence, that crushable aluminum acts as a very rough form of emergency suspension meant to minimize potential damage to the fragile structure of Falcon booster propellant tanks at the cost of its landing legs. In the case of B1048’s third landing, the lean appears to be no more than a few degrees – scarcely out of the ordinary, at least relative to past leaning boosters. Most notably, Falcon 9 B1023 experienced a similar anomaly and a far worse lean after its first landing, an experience that did not apparently impact its ability to launch for the second time as a side booster for Falcon Heavy’s inaugural launch.

B1048’s slight departure from a perfect trajectory should thus pose no problem for in-place plans for the rocket’s fourth (and likely final) launch. Known as Crew Dragon’s in-flight abort (IFA) test, SpaceX specifically requested the inclusion of a second abort test (above and beyond NASA’s testing requirements) to fully verify that astronauts could be pulled to safety at any point during launch. In 2015, the company completed a pad abort test of Crew Dragon, demonstrating that the spacecraft could escape from a failing rocket while static on the launch pad. The in-flight abort is precisely what it sounds like: a demonstration that Crew Dragon can safely escape a failing rocket while in flight. More than simply being in flight, the goal is to demonstrate a successful abort at the point of peak aerodynamic stress of Falcon 9 and Dragon, known as Max Q.
For Cargo Dragon launches, Falcon 9 has typically averaged dynamic forces of about 25 kPa (~4 psi), roughly equivalent to 2.5 tons of force per square meter. During launch, either the payload fairing or Cargo/Crew Dragon are subjected directly to those forces, often requiring a significant period of lower throttle to mitigate the forces those sensitive assemblies experience. Given that Crew Dragon’s abort scenario accelerates the capsule and trunk from a relative speed of zero to nearly 350 mph (150 m/s) in five seconds, the dynamic forces (i.e. mechanical loads and heating) the spacecraft is experiencing could jump 50% or more almost instantaneously.

After Crew Dragon aborts, the Falcon 9 stack – featuring B1048 and a full-fidelity upper stage with a mass simulator in place of its MVac engine – will be instantaneously exposed to those same dynamic forces, experientially equivalent to bellyflopping from an Olympic-height diving platform. The upper stage may actually be better off than the booster thanks to the generally smooth dome at its stern, whereas Falcon 9’s booster would have its interstage – a deep, open cylinder – exposed to the same airflow if or when the upper stage is torn away. At the point of abort, Falcon 9 will most likely be in the process of shutting down its Merlin 1D engines, effectively removing the booster’s control authority and leaving it at the mercy of the atmosphere. SpaceX’s CRS-7 Cargo Dragon failure (caused by the second stage losing structural integrity mid-flight) is actually a decent representation of what is likely to happen to B1048 and its upper stage.
Given the potential destructive power B1048 will face, not to mention the fact that the booster will likely not have grid fins or landing legs installed, today’s recovery will probably be the last time the rocket returns to port and prepares for another launch. Explicitly dependent upon the refurbishment of DM-1’s Crew Dragon capsule, SpaceX’s in-flight abort is not expected to occur until June 2019, although Musk has indicated that the aspirational target is to perform the test as early as April, perhaps less than 60 days after the capsule is scheduled to land in the Atlantic Ocean.

SpaceX stock did the opposite of what most of Wall Street expected this week, when the day designed to be its most dangerous turned into a rally, and the rally kept going.
Thursday marked the first major lockup expiration since SpaceX’s June IPO, making roughly 911.5 million insider held shares eligible to trade for the first time, more than doubling the company’s public float. Analysts and short sellers had spent weeks bracing for a flood of selling, especially after the stock fell 13 percent following its first earnings report as a public company on Tuesday. Instead, shares rose 6.1 percent Thursday to close at $114.92, and by Friday they were trading near $129, up more than another 12 percent on the day.
SpaceX shorts get warned by Musk ally, echoing Tesla’s early struggles
The setup made the outcome notable. Short interest had climbed to roughly 34 percent of the float heading into earnings, among the highest of any large cap stock, with about 95 percent of available shares to borrow already on loan. CEO Elon Musk warned short sellers twice in the weeks before the lockup, writing on X that “the survival probability of firms who maintain a significant short position in SpaceX over time is very low,” then following up on the morning of earnings with “I try to warn them, but they just double down.”
When the newly unlocked shares hit the market and the selloff never showed up, some of that short position appears to have started unwinding. TipRanks reported that options activity shifted toward bullish strategies like put selling and risk reversals following the rally, with roughly $600 million in options premium trading Thursday alone. Retail buyers also stepped in during the earnings dip, according to Vanda Research.
The fundamentals behind the stock have not changed much in a week. SpaceX’s revenue nearly doubled year over year to $7.8 billion, with Starlink subscribers doubling to 12 million and the company’s AI segment growing 247 percent. What spooked investors on Tuesday was the spending side. Capital expenditures jumped to more than $18 billion for the quarter, up from $2.8 billion a year earlier, with AI investment alone rising from $749 million to $15.8 billion. Wall Street remains split on whether that spending is building infrastructure SpaceX needs or outrunning what the business can currently support, a debate Teslarati has tracked since shares first came under pressure.
None of that resolves the bigger question hanging over the stock. Thursday’s release was only the first of nine staggered lockup tranches, with roughly $800 billion worth of additional shares scheduled to become eligible through October, and Musk’s own stake stays locked until next June. If this week is any indication, the market is treating that supply as something it can absorb rather than something to fear, at least for now.

Tesla’s mysterious Robovan makes a sneak peek with Optimus in Terafab video
Elon Musk shared a new Terafab video showing Optimus, Robovans, and a stunningly futuristic campus.
Elon Musk posted a new video of Terafab on X Thursday morning, and the most eye-catching details in it were not the building itself, but two products still awaiting production: Optimus and the Robovan.
The concept render, credited to SpaceX, shows Optimus robots working the grounds of the roughly 2.5-mile-long facility planned for the Gibbons Creek site in Grimes County, while a Robovan glides along an elevated roadway cutting through the building itself, sharing the frame with a Tesla Semi and a Cybercab.
Robovan is the boxy, driverless people and cargo mover Musk unveiled alongside Cybercab at Tesla’s “We, Robot” event in October 2024. He pitched it as a way to move up to 20 passengers at once, or handle freight instead, at a target cost he claimed could fall under a dollar a mile, with no steering wheel or pedals, the same layout as Cybercab. Nearly two years later, Robovan still has no confirmed production timeline and has not shown up in any factory footage, which makes Thursday’s render one of the only recent looks at the vehicle in any form.

Optimus has moved further along. Tesla began converting Fremont’s old Model S and Model X assembly line into a Gen 3 Optimus production line earlier this year, and Musk visited the site on July 1 to mark the changeover. A second, larger Optimus plant is under construction at Giga Texas, targeting volume production in summer 2027 and eventual capacity of 10 million units a year. Tesla AI lead Ashok Elluswamy said this month the robot has “big shoes to fill” in replacing the S and X line, while Musk has repeatedly called Optimus the company’s biggest product of any kind, with a long-term price he has pegged between $20,000 and $30,000.

“Terafab Texas will be the largest and most valuable building on Earth by far,” Musk wrote alongside the clip. “And it will be stunningly beautiful.”
One quote post summed up the reaction: “Futuristic scene with RoboVan + Cybercab + Tesla Semi + Optimus.”
Beyond the vehicles, the architecture wrapped around them stands out too. The building’s facade is canted at sharp angles, with illuminated horizontal bands running through what appears to be a multi level interior visible from outside. Below the elevated roadway, pedestrians walk along a plaza next to a reflecting pool, and the skyline behind the campus is dotted with angular spires that read more like sculpture than infrastructure, a departure from the strictly utilitarian look of Gigafactory Texas or Starbase.
The timing tracks with what Terafab representative Riley Trennell told Grimes County residents on Wednesday, when he said renderings of the facility would be released “within days.” Musk’s post followed less than 24 hours later, and Texas Governor Greg Abbott’s office sent out its own release Thursday confirming the project. As Teslarati reported this morning, Terafab’s tax abatement agreements with Grimes County are now signed and active, and SpaceX has sent the county its first $10 million payment under that deal. The dollar figure tied to this phase of construction, per Reuters, is $16.8 billion, one of the first hard capital expenditure numbers attached to Terafab since Musk unveiled the joint Tesla-SpaceX-xAI venture in March.Reaction on X ranged from enthusiastic to skeptical. “God Bless Texas! Everything is bigger and better in Texas!” one reply read. Another was more measured: “Terafab in a decade…..”
Whether the finished building matches the render is a separate question from whether Musk wanted people talking about the render itself. Less than a day after posting, the video had already crossed 5.5 million views.

Space finally faced the people living next to its next Terafab mega-project
SpaceX confirmed Terafab’s Grimes County site is locked in, with construction starting within months.
SpaceX and Terafab representatives sat across from Grimes County residents for the first time on Wednesday, telling a packed Commissioners Court room that the $55 billion chip manufacturing project is now a done deal at the Gibbons Creek Reservoir site.
The meeting followed a $10 million check SpaceX sent the county earlier this week, satisfying a payment deadline built into the tax abatement agreement both sides signed in June. Elon Musk shared a post on X confirming the payment, and County Judge Joe Fauth told the San Antonio Express-News his office deposited the check after it beat its deadline.
Wednesday’s session, first reported by KBTX, moved the project from paperwork to construction. Terafab representative Riley Trennell told residents the JETI tax break agreements with Iola ISD and Anderson-Shiro CISD are signed and active, and that civil work and foundation prep are starting almost immediately. Renderings of the facility could be released within days, he said, with construction beginning within months.

Elon Musk launches TERAFAB: The $25B Tesla-SpaceXAI chip factory that will rewire the AI industry
Musk first announced Terafab in March as a joint venture between Tesla, SpaceX and xAI aimed at producing over a terawatt of AI compute annually, an amount that dwarfs the roughly 20 gigawatts the entire global chip industry produces today. Intel joined as a manufacturing partner in April. Musk has said the project needed its own day in the spotlight rather than being squeezed into an earnings call, and for months the Grimes County site remained unconfirmed even as reporting pointed there.

SpaceX attorney Buck Brannon used Wednesday’s meeting to note that the company’s abatement is roughly 78 percent, not the 100 percent some earlier reports suggested. In exchange, SpaceX will pay Grimes County a fixed $20 million a year for 35 years, a total of $710 million, which Brannon said exceeds the $14 million Tesla paid Travis County in 2025.
SpaceX also addressed environmental concerns that have followed the project since Musk’s Terafab partnership with Intel was announced. Representatives said Terafab will not raise electric bills for other ratepayers, will not deplete local water supplies and will not draw down the Navasota River. SpaceX confirmed it owns the Navasota River pumping station, which it plans to use to divert stormwater into the Gibbons Creek Reservoir, and said it will build its own natural gas plants to power the facility rather than pulling from the ERCOT grid.
Grimes County commissioners also approved an addendum letting county employees use ten approved AI chatbots for work, including Grok.
