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.

Lufthansa Group to equip Starlink on its 850-aircraft fleet
Under the collaboration, Lufthansa Group will install Starlink technology on both its existing fleet and all newly delivered aircraft, as noted by the group in a press release.
Lufthansa Group has announced a partnership with Starlink that will bring high-speed internet connectivity to every aircraft across all its carriers.
This means that aircraft across the group’s brands, from Lufthansa, SWISS, and Austrian Airlines to Brussels Airlines, would be able to enjoy high-speed internet access using the industry-leading satellite internet solution.
Starlink in-flight internet
Under the collaboration, Lufthansa Group will install Starlink technology on both its existing fleet and all newly delivered aircraft, as noted by the group in a press release.
Starlink’s low-Earth orbit satellites are expected to provide significantly higher bandwidth and lower latency than traditional in-flight Wi-Fi, which should enable streaming, online work, and other data-intensive applications for passengers during flights.
Starlink-powered internet is expected to be available on the first commercial flights as early as the second half of 2026. The rollout will continue through the decade, with the entire Lufthansa Group fleet scheduled to be fully equipped with Starlink by 2029. Once complete, no other European airline group will operate more Starlink-connected aircraft.
Free high-speed access
As part of the initiative, Lufthansa Group will offer the new high-speed internet free of charge to all status customers and Travel ID users, regardless of cabin class. Chief Commercial Officer Dieter Vranckx shared his expectations for the program.
“In our anniversary year, in which we are celebrating Lufthansa’s 100th birthday, we have decided to introduce a new high-speed internet solution from Starlink for all our airlines. The Lufthansa Group is taking the next step and setting an essential milestone for the premium travel experience of our customers.
“Connectivity on board plays an important role today, and with Starlink, we are not only investing in the best product on the market, but also in the satisfaction of our passengers,” Vranckx said.

SpaceX gains favor as Pentagon embraces Musk-style defense reform
The remarks highlighted Musk’s improving relationship with the White House, as well as SpaceX’s growing role in U.S. defense.
SpaceX emerged as a clear beneficiary of the Trump administration’s renewed push to accelerate military innovation, as Defense Secretary Pete Hegseth openly praised Elon Musk’s private space enterprise during a visit to the company’s Starbase launch site in Texas.
The remarks highlighted Musk’s improving relationship with the White House, as well as SpaceX’s growing role in U.S. defense.
Hegseth embraces Elon Musk’s pace
Speaking at SpaceX’s Starbase facility in Brownsville, Texas, Hegseth criticized what he described as a “risk-averse culture” among traditional defense contractors and called for faster innovation modeled after Musk’s approach. He confirmed that the Department of Defense plans to integrate Musk’s Grok AI platform into Pentagon systems, which is part of the administration’s efforts to make the U.S. military an “AI-first warfighting force.”
Hegseth stated that the Pentagon intends to deploy AI models across both classified and unclassified networks, signaling a willingness to push past earlier efforts to limit military use of artificial intelligence. His comments aligned closely with President Donald Trump’s recent call for a $500 billion increase in defense spending, Bloomberg News noted. Trump has also warned major contractors that slower production and shareholder-focused practices could put future contracts at risk.
While Hegseth criticized legacy defense firms, SpaceX was held up as an example of how aggressive timelines, vertical integration, and iterative development could reshape defense strategies. “We need to be blunt here; we can no longer afford to wait a decade for our legacy prime contractors to deliver a perfect system. Winning requires a new playbook. Elon wrote it with his algorithm: question every requirement, delete the dumb ones and accelerate like hell,” Hegseth said.
SpaceX’s expanding defense role comes into focus
SpaceX has become one of the U.S. government’s most important aerospace partners. The company holds roughly $4 billion in NASA contracts to develop Starship into a lunar lander, while also serving as a key launch provider for sensitive national security payloads using its Falcon 9 and Falcon Heavy rockets.
During the visit, Musk highlighted that his ambitions extend beyond defense contracts, reiterating long-term goals of interplanetary travel and eventual exploration beyond the solar system. Still, the optics of the event reinforced how closely SpaceX’s capabilities now align with U.S. strategic priorities.
The appearance also marked another step in Musk’s political rehabilitation after a public falling-out with the White House last year. Since leaving his role leading the Department of Government Efficiency, Musk has gradually reengaged with the administration, reconnecting with U.S. President Donald Trump during slain conservative activist Charlie Kirk’s tribute and attending events at the White House. Trump’s also recently suggested that Starlink could help restore internet access in Iran.

Donald Trump turns to Elon Musk and Starlink amid Iran internet blackout
Donald Trump has stated that he plans to speak with SpaceX CEO Elon Musk about restoring internet access in Iran.
Donald Trump has stated that he plans to speak with SpaceX CEO Elon Musk about restoring internet access in Iran, as authorities in the country implement an internet blackout amid nationwide anti-government protests.
Trump points to Starlink
Speaking to reporters in Washington, Trump said Musk would be well-suited to help restore connectivity in Iran, citing his experience operating large-scale satellite networks, as noted in a Reuters report. “He’s very good at that kind of thing, he’s got a very good company,” Trump said.
Iran has experienced a near-total internet shutdown for several days, severely limiting the flow of information as protests escalated into broader demonstrations against the country’s rulers.
Starlink has previously been used in Iran during periods of unrest, allowing some users to access the global internet despite government blocks. Neither Musk nor SpaceX immediately commented on Trump’s remarks, but Musk has publicly supported efforts to provide Starlink access to Iranians during earlier periods of unrest.
Renewed Trump–Musk ties
Trump’s comments come amid a thaw in his previously strained relationship with Musk. The two had a public falling-out last year over domestic policy disagreements but have since appeared together publicly, including at Trump’s Mar-a-Lago resort. The renewed ties now intersect with foreign policy, as Starlink has become a strategic tool in regions facing censorship or conflict.
The satellite service has also played a prominent role elsewhere, most notably in Ukraine, highlighting both its potential impact and the political sensitivities surrounding its use. In Iran, Starlink support previously followed coordination between Musk and U.S. officials during protests in 2022.
The current internet blackout in Iran has drawn international attention, with rights groups estimating hundreds of deaths and thousands of arrests since demonstrations intensified late last year. Iranian authorities have not released official casualty figures, and outside verification remains limited due to restricted communications.
