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 checks off 49 lunar lander milestones in push toward Artemis III
SpaceX has revealed that it has completed 49 major milestones for NASA’s Human Landing System (HLS) program, marking significant progress in the development of the Starship lunar lander that will deliver astronauts to the Moon.
The updates were detailed in SpaceX’s new blog post To the Moon and Beyond, which was recently posted on the private space company’s official website.
As noted by SpaceX, the 49 milestones that were completed by its HLS team were “tied to developing the subsystems, infrastructure, and operations” needed to safely land humans back into the lunar surface. SpaceX noted that it has only received funding on contractual milestones that have been successfully completed, the vast majority of which have been achieved on time or ahead of schedule.
Following are highlights of SpaceX’s completed milestones, as per the company’s post.
For the first time in our existence, we possess the means, technology, and, for the moment, the will to establish a permanent human presence beyond Earth. Starship is designed to make this future a reality → https://t.co/dGAZiB4rr3 pic.twitter.com/WsTg44G3oz — SpaceX (@SpaceX) October 30, 2025

SpaceX sets the record straight on Jim Bridenstine and Artemis 3
SpaceX argued that Bridenstine’s comments should be taken with a grain of salt as he is working as a paid lobbyist for companies that are competing for NASA contracts.
SpaceX pushed back firmly against former NASA administrator Jim Bridenstine after he questioned the agency’s reliance on Starship for the Artemis 3 Moon mission.
In a detailed thread on X, SpaceX argued that Bridenstine’s comments should be taken with a grain of salt as he is working as a paid lobbyist for companies that are competing for NASA contracts.
Bridenstine’s comments on Starship and Artemis 3
Bridenstine and fellow former NASA chief Charlie Bolden noted during a recent symposium that NASA’s current Artemis strategy is approaching zero chance of beating China to the Moon. Bridenstine expressed skepticism that NASA’s current architecture, which is expected to use Starship to transport astronauts to and from the lunar surface, could succeed in time.
“Starship is a tremendously important vehicle for the future,” Bridenstine said, as per Space News. “It’s going to deliver large mass to low Earth orbit for a long time, and it’s going to drive down costs and increase access. But if you need a moon lander, it’s going to take time.”
SpaceX responds to the former NASA administrator’s comments
In a series of posts on X, SpaceX noted that while the company is very thankful to the former NASA administrator for helping create the Artemis Program, his comments about Starship might not necessarily be coming from a place of objectivity.
SpaceX’s comments are as follows: “Like many Americans, we are thankful for Mr. Bridenstine’s service leading NASA at one point. He deserves credit for spearheading the creation of the Artemis Program. After departing NASA, he created a lobbying firm called the Artemis Group, representing a host of aerospace companies vying for NASA business.
“Mr. Bridenstine’s current campaign against Starship is either misguided or intentionally misleading. SpaceX was selected to design and develop a Human Landing System for Artemis along with Blue Origin and Dynetics during Mr. Bridenstine’s tenure as NASA Administrator.
“Starship was then selected by NASA for the Artemis III mission through fair and open competition after being identified as the best and lowest risk technical option – and the lowest price by a wide margin – by the civil servant team appointed to lead the agency’s exploration mission by Mr. Bridenstine himself.
“The decision to select Starship was confirmed repeatedly following protest and litigation from the companies not selected which delayed the start of work on the contract for many months. Mr. Bridenstine’s recent musings promoting a new landing system – going so far as to invoke the Defense Production Act – are being misreported as though they were the unbiased thoughts of a former NASA Administrator. They are not.
“To be clear, he is a paid lobbyist. He is representing his clients’ interests, and his comments should be seen for what they are – a paid lobbyist’s effort to secure billions more in government funding for his clients who are already years late and billions of dollars overbudget,” SpaceX wrote.
