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.

CEO Elon Musk revealed that some of the engines on Starship did not start, which automatically triggers a launch abort. Two of the Raptor engines will be removed and replaced.
To be confident of a good flight, 2 Raptors will be removed & replaced. Most probable launch timing is early next week.

SpaceX officially announced the new launch window this morning.
Starship’s 13th test launch comes with a few new objectives, but SpaceX does not plan to attempt a catch of the booster, which it has done several times in the past.
For Starship’s Upper Stage, there are some adjustments to ensure engine reusability that will be assessed during the ascent, and 20 operational Starlink V3 satellites are also set to make their way into space. SpaceX also plans to attempt an in-space relight of a single Raptor engine, which is a critical demonstration for future orbital deorbit, refueling, and deep space maneuvers.
Ultimately, it will splash down in the Indian Ocean.
The continuous tests help SpaceX advance the Starship program toward eventual full reusability, operational Starlink V3 deployment, and future missions, which include NASA’s Artemis program.

SpaceX Starship Flight 13 aborted at Zero and Musk just told us what broke
Four Raptor engines failed to ignite at T-zero, forcing SpaceX to scrub Starship Flight 13 Thursday.
SpaceX scrubbed the Starship Flight 13 launch attempt Thursday evening at the last possible moment, after four of the Super Heavy booster’s 33 Raptor 3 engines failed to ignite during the startup sequence. The 90-minute window had opened at 6:45 p.m. EDT from Starbase in Boca Chica, Texas, and the countdown had proceeded without issue all day, with more than 11.5 million pounds of liquid methane and liquid oxygen being fully loaded into the rocket before the automated abort triggered. SpaceX’s launch directors posted on X, “Standing down from today’s flight test attempt,” and shut down the livestream shortly after.
Musk confirmed the root cause within hours. “Some of the engines didn’t start, triggering an automatic launch abort,” he wrote on X. “To be confident of a good flight, 2 Raptors will be removed and replaced. Most probable launch timing is early next week.” SpaceX engineers began draining propellant tanks immediately and Booster 20 was rolled back to its hangar for inspection.
The timing adds a layer of significance that did not exist during any of the previous 12 Starship flights. This is the first time SpaceX has attempted to launch Starship since the company made its stock market debut in June, listing under ticker SPCX at $135 per share. Public investors are now watching every Starship outcome in real time, and a last-second abort carries more visibility than it would have six months ago.
Flight 13 was designed to be one of the most consequential tests in the program’s history. It was set to carry 20 Starlink V3 satellites, the first operational payload Starship has ever attempted to deploy. Six of those satellites carried external cameras to photograph Starship’s heat shield from the outside during flight, which would act as a self-inspection approach SpaceX has never attempted before. The mission also needed to complete a Raptor engine relight in space, a step SpaceX skipped on Flight 12 in May after losing an engine during ascent. That Flight 12 booster also flipped 90 degrees off course during its boostback burn when five engines failed to reignite.
SpaceX has not announced an official next launch date. Musk’s “early next week” window points to July 21 or 22 at the earliest, pending the engine swap and a return to the pad.

Elon Musk’s Texas ranch to showcase the lifelong work that changed the world
Elon Musk is building a product gallery at his Texas ranch spanning his lifelong inventions.
Elon Musk took to X earlier today, noting “Am putting together a product gallery at my ranch in Texas.” in response to a resurfaced famous quote from JPMorgan CEO Jamie Dimon’s wherein he draw parallels of the Tesla CEO to legendary physicist Albert Einstein.
Dimon made the remark at the World Economic Forum in Davos, Switzerland back in January 2025, telling CNBC at the time, “SpaceX, Tesla, Neuralink, I mean, the guy is our Einstein.” The remark seemingly ended a long-time feud between the two high profile execs.
While details are thin about the exact location of Elon Musk’s Texas ranch and any pending projects that would serve as a gallery and homage to his portfolio of revolutionary product inventions spanning from 1984 to 2025, land acquisition records point to roughly a location of several thousand acres in Bastrop County, east of Austin near the Colorado River and held through an LLC called Horse Ranch LLC that’s managed by Musk’s longtime personal friend and family wealth manager Jared Birchall. Birchall also serves as the CEO of Neuralink.
Tesla’s “ecological paradise” in Giga Texas may be larger than expected
The broader Bastrop County footprint surrounding the ranch has grown significantly. Entities tied to Musk have accumulated approximately 2,000 acres in Bastrop County as of mid-2026, up from 700 acres earlier in the year, with possibly as much as 6,000 acres acquired in total across Bastrop and Travis counties based on deed records.
No completion date for the gallery has been announced and Musk has not confirmed whether it will be open to the public. As Teslarati has reported, SpaceX just completed the largest IPO in history raising $75 billion, a milestone that makes this particular moment in Musk’s career a natural inflection point for looking back at what he has built through the years.

Starting with Blastar, a simple space shooter game Musk coded at 12 years old and sold to a South African magazine for $500. From there the timeline moves through a commercial career that started with Zip2 in 1995, a city guide software company sold to Compaq for roughly $300 million in 1999. That was followed by X.com in 1999, which merged with Confinity to become PayPal, acquired by eBay in 2002 for $1.5 billion. SpaceX came in 2002, Tesla in 2003, SolarCity in 2006, the Supercharger network in 2012, Neuralink in 2016, The Boring Company in 2016, OpenAI co-founded in 2015, X acquired in 2022, xAI in 2023, Optimus in 2024, the Cybercab in 2026, and most recently SpaceXAI following the SpaceX and xAI merger. The gallery will also likely include items that blur the line between product and cultural artifact, among them The Boring Company’s Not-a-Flamethrower from 2018, Tesla Short Shorts from 2020, and Burnt Hair perfume released under X in 2022.
