SpaceX’s first Falcon 9 Block 5 booster casualty battered but still intact in aerial photos
Shortly after successfully sending a reused Cargo Dragon spacecraft on its way towards the International Space Station (ISS), SpaceX Falcon 9 Block 5 booster B1050 experienced an anomaly with its grid fins during a planned landing, resulting in a shockingly soft (but unintentional) landing just off the Florida coast.
By some minor miracle, the drastically off-nominal loads experienced by the booster during its unintended departure from controlled flight somehow did not rise to the bar of structural failure. Nevertheless, now floating a handful of miles east of Port Canaveral’s mouth, B1050 did not make it through the ordeal unscathed.

A little more than 24 hours after the booster found itself floating sideways in the Atlantic Ocean, B1050 had floated a solid ten miles south of its original position into waters and airspace that no longer fell under the purview of Cape Canaveral Air Force Station, technically a military outpost. As the captains of tugboat Eagle and SpaceX support vessel GO Quest discussed the logistics of returning the booster to port with the local harbormaster and US Coast Guard, Teslarati photographer Tom Cross chartered a local helicopter to get a slightly better view of the waterlogged rocket and its ad-hoc recovery operations.
A casualty of war (with the air)
Second only to the fact that the booster appears to be in disproportionately good shape considering the circumstances, by far the most noteworthy feature of the newest addition to SpaceX’s marine fleet is the sheer damage suffered by B1050’s interstage, the black carbon fiber composite structure that topsFalcon 9 Block 5 boosters and hosts its grid fins and stage separation mechanism.
Revealed from an aerial perspective, it almost looks as if one side of the composite cylinder was smashed with a giant hammer, tearing off at least 20% of the entire interstage – including one of four titanium grid fins – while leaving another large segment hanging on by only partially-figurative carbon fiber threads.

It’s not 100% clear why B1050’s interstage was so readily destroyed but a narrative can certainly be drawn from the current public record. After its grid fins lost hydraulic power and became stuck at an extreme angle, B1050 almost immediately lost control and began rapidly and quite brutally spinning and flailing, tossed around as it hurtled through the air at supersonic speeds. Being a predominately smooth cylinder, Falcon 9’s first stage is inherently prone to rotation in the presence of high-velocity air currents, which is why its grid fins are an absolute necessity for maintaining control authority during in-atmosphere “flights”.

In a show that will turn the stomach of anyone familiar with a rocket’s typically narrow load tolerances, Falcon 9 B1050 experienced extreme aerodynamic stresses during the worst of its uncontrolled tumble, to the extent that the entire booster and interstage can be seen visibly twisting at least 5 degrees left and right from the perspective of an onboard camera. In the video above, focus on the center of Falcon 9’s grid fins during the first and last 5-10 seconds to properly visualize the extreme forces at play.
It might look fairly innocent to the untrained eye, but keep in mind that Falcon 9’s interstage is no more than a couple of inches thick and is absolutely massive, stretching 3.7m (~12 ft) in diameter. Perhaps even more importantly, the damage to the interstage has almost without a doubt rendered it unusable from the perspective of SpaceX’s established methods of safely moving and manipulating Falcon 9 boosters.

All of those methods rely on adapters that attach to the interstage to lift the rocket vertically or support part of its ~30-ton dry mass horizontally. Lacking a sound interstage, it’s now entirely unclear how SpaceX might go about getting B1050 onto land without damaging it further. In simpler terms, this bodes very, very badly for any plans to safely reuse B1050 in the near (or distant) future. After suffering loads that severely weakened and ultimately tore its interstage to pieces, it’s reasonable to assume that the rest of the rocket’s lithium-aluminum propellant tanks experienced stresses that are at least roughly comparable.
If that’s the case, perhaps the only real hope for B1050’s ‘reuse’ will be the recovery of certain subcomponents and miscellaneous parts that may have made it through the ordeal unscathed or with only minor damage. The three remaining titanium grid fins are a guaranteed recovery, while COPVs, cold gas thrusters, avionics boxes, and maybe even some of its nine Merlin 1D engines could be salvageable with some level of refurbishment.
In the meantime, the tentative plan right now is to two B1050 into Port Canaveral sometime after dawn tomorrow, either ending up at drone ship OCISLY’s berth or another less-developed section of the port.

California city weighs banning Elon Musk companies like Tesla and SpaceX
A resolution draft titled, “Resolution Ending Engagement With Elon Musk-Controlled Companies and To Encourage CalPERS To Divest Stock In These Companies,” alleges that Musk “has engaged in business practices that are alleged to include violations of labor laws, environmental regulations, workplace safety standards, and regulatory noncompliance.”
A California City Council is planning to weigh whether it would adopt a resolution that would place a ban on its engagement with Elon Musk companies, like Tesla and SpaceX.
The City of Davis, California, will have its City Council weigh a new proposal that would adopt a resolution “to divest from companies owned and/or controlled by Elon Musk.”
This would include a divestment proposal to encourage CalPERS, the California Public Employees Retirement System, to divest from stock in any Musk company.
A resolution draft titled, “Resolution Ending Engagement With Elon Musk-Controlled Companies and To Encourage CalPERS To Divest Stock In These Companies,” alleges that Musk “has engaged in business practices that are alleged to include violations of labor laws, environmental regulations, workplace safety standards, and regulatory noncompliance.”
It claims that Musk “has used his influence and corporate platforms to promote political ideologies and activities that threaten democratic norms and institutions, including campaign finance activities that raise ethical and legal concerns.”
If adopted, Davis would bar the city from entering into any new contracts or purchasing agreements with any company owned or controlled by Elon Musk. It also says it will not consider utilizing Tesla Robotaxis.

A staff report on the proposal claims there is “no immediate budgetary impact.” However, a move like this would only impact its residents, especially with Tesla, as the Supercharger Network is open to all electric vehicle manufacturers. It is also extremely reliable and widespread.
Regarding the divestment request to CalPERS, it would not be surprising to see the firm make the move. Although it voted against Musk’s compensation package last year, the firm has no issue continuing to make money off of Tesla’s performance on Wall Street.
The decision to avoid Musk companies will be considered this evening at the City Council meeting.
The report comes from Davis Vanguard.
It is no secret that Musk’s political involvement, especially during the most recent Presidential Election, ruffled some feathers. Other cities considered similar options, like the City of Baltimore, which “decided to go in another direction” after awarding Tesla a $5 million contract for a fleet of EVs for city employees.

Starlink restrictions are hitting Russian battlefield comms: report
The restrictions have reportedly disrupted Moscow’s drone coordination and frontline communications.
SpaceX’s decision to disable unauthorized Starlink terminals in Ukraine is now being felt on the battlefield, with Ukrainian commanders reporting that Russian troops have struggled to maintain assault operations without access to the satellite network.
The restrictions have reportedly disrupted Moscow’s drone coordination and frontline communications.
Lt. Denis Yaroslavsky, who commands a special reconnaissance unit, stated that Russian assault activity noticeably declined for several days after the shutdown. “For three to four days after the shutdown, they really reduced the assault operations,” Yaroslavsky said.
Russian units had allegedly obtained Starlink terminals through black market channels and mounted them on drones and weapons systems, despite service terms prohibiting offensive military use. Once those terminals were blocked, commanders on the Ukrainian side reported improved battlefield ratios, as noted in a New York Post report.
A Ukrainian unit commander stated that casualty imbalances widened after the cutoff. “On any given day, depending on your scale of analysis, my sector was already achieving 20:1 (casuality rate) before the shutdown, and we are an elite unit. Regular units have no problem going 5:1 or 8:1. With Starlink down, 13:1 (casualty rate) for a regular unit is easy,” the unit commander said.
The restrictions come as Russia faces heavy challenges across multiple fronts. A late January report from the Center for Strategic and International Studies estimated that more than 1.2 million Russian troops have been killed, wounded, or gone missing since February 2022.
The Washington-based Institute for the Study of War also noted that activity from Russia’s Rubikon drone unit declined after Feb. 1, suggesting communications constraints from Starlink’s restrictions may be limiting operations. “I’m sure the Russians have (alternative options), but it takes time to maximize their implementation and this (would take) at least four to six months,” Yaroslavsky noted.

SpaceX and xAI tapped by Pentagon for autonomous drone contest
The six-month competition was launched in January and is said to carry a $100 million award.
SpaceX and its AI subsidiary xAI are reportedly competing in a new Pentagon prize challenge focused on autonomous drone swarming technology, as per a report from Bloomberg News.
The six-month competition was launched in January and is said to carry a $100 million award.
Bloomberg reported that SpaceX and xAI are among a select group invited to participate in the Defense Department’s effort to develop advanced drone swarming capabilities. The goal is reportedly to create systems that can translate voice commands into digital instructions and manage fleets of autonomous drones.
Neither SpaceX, xAI, nor the Pentagon’s Defense Innovation Unit has commented on the report, and Reuters said it could not independently verify the details.
The development follows SpaceX’s recent acquisition of xAI, which pushed the valuation of the combined companies to an impressive $1.25 trillion. The reported competition comes as SpaceX prepares for a potential initial public offering later this year.
The Pentagon has been moving to speed up drone deployment and expand domestic manufacturing capacity, while also seeking tools to counter unauthorized drone activity around airports and major public events. Large-scale gatherings scheduled this year, including the FIFA World Cup and America250 celebrations, have heightened focus on aerial security.
The reported challenge aligns with broader Defense Department investments in artificial intelligence. Last year, OpenAI, Google, Anthropic, and xAI secured Pentagon contracts worth up to $200 million each to advance AI capabilities across defense applications.
Elon Musk previously joined AI and robotics researchers in signing a 2015 open letter calling for a ban on offensive autonomous weapons. In recent years, however, Musk has spoken on X about the strengths of drone technologies in combat situations.
