SpaceX has suffered its second rocket landing failure of 2020 despite the fact that both lost Falcon 9 boosters successfully launched 60 Starlink satellites, an anomaly that CEO Elon Musk says will need a “thorough investigation”.

After a rare last-second launch abort on March 15th and a three-day range-related delay, Falcon 9 booster B1048 lifted off with 60 upgraded Starlink v1.0 satellites on its fifth orbital-class mission. At least for the first two and half minutes, the booster performed precisely as intended, carrying a fueled upper stage and its ~16 metric ton (36,000 lb) payload to an altitude of 55 km (34 mi) and a velocity of 1.8 km/s (1.1 mi/s). However, about 10 seconds before the booster reached main engine cut-off (MECO) and stage separation, something went wrong.

While there is some ambiguity in his response, according to Musk, at least one of Falcon 9 B1048’s nine Merlin 1D engines performed an early shutdown before MECO. The rocket’s computer immediately accounted for the anomaly, extending the remaining eight-engine booster burn 5-7 seconds beyond the nominal timeline to ensure mission success. While the booster’s loss is still disappointing and the premature engine shutdown more than a little concerning, it’s critical to remember that mission success was ensured. Just 15 minutes after liftoff, the rocket’s upper stage successfully spun up and deployed another 60 Starlink satellites, bringing SpaceX’s operational constellation to an incredible ~350 satellites.

Based on live views available from SpaceX’s launch webcast, it appears that Falcon 9’s “early engine shutdown” is more of a euphemism for a fairly violent engine failure that triggered an instantaneous cutoff, preventing damage elsewhere. While SpaceX would certainly rather avoid in-flight engine failures, Falcon 9’s nine Merlin 1D booster engines are installed inside an aluminum ‘octaweb’ structure that transmits their thrust to the rest of the rocket but also effectively quarantines each engine in a blast-proof bunker.

Despite the partial failure, Falcon 9 B1048 continued to fight its way through its landing trajectory until it either ran out of propellant or burnt up during reentry. (SpaceX)

Nevertheless, the rocket’s highly-attuned software and affected octaweb engine bunker did their jobs, instantly shutting the failing engine down while also preventing the explosion and resulting shrapnel from damaging the rest of the rocket. More likely than not, B1048’s autonomous decision to always put mission success before booster recovery lead the booster to expend a majority of the propellant needed for its landing attempt to make up for the 10 or so seconds operating at only ~89% thrust.

As a result, B1048 may have simultaneous subjected itself to a much more extreme atmospheric reentry and run out of propellant before it could complete (or maybe even start) its drone ship landing burn. There’s also a chance that the engine that failed was one of the three engines required for reentry and landing burns, an asymmetry that would be impossible to overcome on the fly. Ultimately, the booster likely impacted the ocean at a near-supersonic velocity, smashing it into aluminum confetti. Thankfully, the late B1048 had a record-breakingly productive career as an orbital-class booster, placing dozens of tons of payload into orbit over five successful launches. Its loss is regrettable but the booster has more than earned its keep.

Aside from two twice-flown Falcon Heavy Block 5 side boosters of unknown status and 2-3 new boosters assigned to critical NASA and US Air Force missions, SpaceX’s fleet is now down to just three flightworthy Falcon 9 boosters. This could dramatically limit its options for near-term commercial flights, as none of those rockets – even assuming flawless launch and landing debuts – will likely be ready for their first reuses until May or June. Meanwhile, B1051 and B1049 have three and four missions under their respective belt and both completed their last launches just 50-70 days ago, while B1059 flew for the second time just two weeks ago. Despite the fact that it successfully completed its fifth mission, B1048’s in-flight engine failure will almost certainly delay upcoming launches, although the degree of those delays is up for debate.

Up next for SpaceX is SAOCOM 1B, an Argentinian radar satellite set to become the first payload launched into a polar orbit from the US East Coast in half a century. Before B1048’s anomaly, the mission was scheduled to launch no earlier than March 30th and could use any of unassigned boosters described above

Tesla’s newest “Folding V4 Superchargers” are key to its most aggressive expansion yet

Tesla’s folding V4 Supercharger ships 33% more per truck, cuts deployment time and cost significantly.

Tesla V4 Supercharger installation ramping in Europe

Tesla is rolling out a folding V4 Supercharger design, an engineering change that allows 33% more units to fit on a single delivery truck, cuts deployment time in half, and reduces overall installation cost by roughly 20%.

The folding mechanism addresses one of the least glamorous but most consequential bottlenecks in charging infrastructure: getting hardware from factory floor to job site efficiently. By collapsing the form factor for transit and unfolding into an operational configuration on arrival, the new design dramatically reduces the logistics overhead that has historically slowed Supercharger rollouts, particularly at large or remote sites where multiple units are needed simultaneously.

The timing aligns with a broader acceleration in Tesla’s network strategy. In March 2026, Tesla’s Gigafactory New York produced its final V3 Supercharger cabinet after more than seven years and 15,000 units, pivoting entirely to V4 cabinet production. The V4 cabinet itself is already a generational leap, delivering up to 500 kW per stall for passenger vehicles and up to 1.2 MW for the Tesla Semi, while supporting twice the stalls per cabinet at three times the power density of its predecessor. The folding transport innovation layers logistical efficiency on top of that technical foundation.

Tesla launches first ‘true’ East Coast V4 Supercharger: here’s what that means

Tesla Charging’s Director Max de Zegher, commenting on the V4 cabinet when it launched, captured the operational philosophy behind these changes: “Posts can peak up to 500kW for cars, but we need less than 1MW across 8 posts to deliver maximum power to cars 99% of the time.” The design philosophy has always been about maximizing real-world throughput, not just peak specs, and the folding transport upgrade extends that thinking into the supply chain itself.

The Boring Company clears final Nashville hurdle: Music City loop is full speed ahead

The Boring Company has cleared its final Nashville hurdles, putting the Music City Loop on track for 2026.

The Boring Company has cleared one of its most significant regulatory milestones yet, securing a key easement from the Music City Center in Nashville just days ago, the latest in a series of approvals that have pushed the Music City Loop project firmly into construction reality.

On March 24, 2026, the Convention Center Authority voted to grant The Boring Company access to an easement along the west side of the Music City Center property, allowing tunneling beneath the privately owned venue. The move follows a unanimous 7-0 vote by the Metro Nashville Airport Authority on February 18, and a joint state and federal approval from the Tennessee Department of Transportation and the Federal Highway Administration on February 25. Together, these green lights have cleared the path for a roughly 10-mile underground tunnel connecting downtown Nashville to Nashville International Airport, with potential extensions into midtown along West End Avenue.

Music City Loop could highlight The Boring Company’s real disruption

Nashville was selected by The Boring Company largely because of its rapid population growth and the strain that growth has placed on surface infrastructure. Traffic has become a persistent problem for residents, convention visitors, and airport travelers alike. The Music City Loop promises an approximately 8-minute underground transit time between downtown and the Nashville International Airport (BNA), removing thousands of vehicles from surface roads daily while operating as a fully electric, zero-emissions system at no cost to taxpayers.

The project fits squarely within a broader vision Musk has championed for years. In responding to a breakdown of the Loop’s construction costs, Musk posted on X: “Tunnels are so underrated.” The comment reflected a longstanding belief that underground transit represents one of the most cost-effective and scalable infrastructure solutions available. The Boring Company has claimed it can build 13 miles of twin tunnels in Nashville for between $240 million and $300 million total, a fraction of what comparable projects cost elsewhere in the country.

The Las Vegas Loop, The Boring Company’s first operational system, has served as a proof of concept. During the CONEXPO trade show in March 2026, the Vegas Loop transported approximately 82,000 passengers over five days at the Las Vegas Convention Center, demonstrating the system’s capacity during large-scale events. Nashville draws millions of convention visitors and tourists each year, and local business leaders have pointed to that same capacity as a major draw for supporting the project.

The Music City Loop was first announced in July 2025. Construction began within hours of the February 25 state approval, with The Boring Company’s Prufrock tunneling machine already in the ground the same evening. The first operational segment is targeted for late 2026, with the full route expected to be complete by 2029. The project represents one of the largest privately funded infrastructure efforts currently underway in the United States.

Elon Musk demands Delaware Judge recuse herself after ‘support’ post celebrating $2B court loss

A banner on the post read “Katie McCormick supports this,” using LinkedIn’s heart-in-hand “support” icon, an endorsement stronger than a simple “like.” Musk’s lawyers argue the action creates “a perception of bias against Mr. Musk,” warranting immediate recusal to preserve judicial impartiality.

Tesla CEO Elon Musk’s legal team has filed a motion demanding that Delaware Chancellor Kathaleen McCormick disqualify herself from an ongoing high-stakes Tesla shareholder lawsuit.

The filing, submitted March 25, cites an apparent LinkedIn “support” reaction from McCormick’s account to a post celebrating a $2 billion jury verdict against Musk in a separate California securities-fraud case.

The move escalates long-simmering tensions between Musk, Tesla, and the Delaware judiciary, where McCormick previously presided over the landmark challenge to Musk’s record $56 billion 2018 compensation package.

Delaware Supreme Court reinstates Elon Musk’s 2018 Tesla CEO pay package

The LinkedIn post was written by Harry Plotkin, a Southern California jury consultant who assisted the plaintiffs who sued Musk over 2022 tweets about his Twitter acquisition. Plotkin praised the trial team for “standing up for the little guy against the richest man in the world.”

The New York Post initially reported the story.

A banner on the post read “Katie McCormick supports this,” using LinkedIn’s heart-in-hand “support” icon, an endorsement stronger than a simple “like.” Musk’s lawyers argue the action creates “a perception of bias against Mr. Musk,” warranting immediate recusal to preserve judicial impartiality.

McCormick swiftly denied intentional endorsement. In a letter to attorneys, she stated she was unaware of the interaction until LinkedIn notified her. She wrote:

“I either did not click the ‘support’ icon at all, or I did so accidentally. I do not believe that I did it accidentally.”

The chancellor maintains the reaction was inadvertent, but critics, including Musk allies, call the explanation implausible given the platform’s deliberate interface.

McCormick’s central role in the Tesla pay-package litigation underscores the stakes. In Tornetta v. Musk, in January 2024, she ruled the 2018 performance-based stock-option grant, potentially worth $56 billion at the time and now valued far higher, was invalid.

The package consisted of 12 tranches of options, each vesting only after Tesla achieved ambitious market-cap and operational milestones. McCormick found Musk exercised “transaction-specific control” over Tesla as a controlling stockholder, the board lacked sufficient independence, and proxy disclosures to shareholders were materially deficient.

Applying the entire-fairness standard, she concluded defendants failed to prove the deal was fair in process or price and ordered full rescission, an “unfathomable” remedy she described as necessary to deter fiduciary breaches.

After the ruling, Tesla shareholders ratified the package a second time in June 2024. McCormick rejected that ratification in December 2024, holding that post-trial votes could not cure defects.

Tesla appealed. On December 19 of last year, the Delaware Supreme Court unanimously reversed the rescission remedy while largely leaving McCormick’s liability findings intact. The high court deemed total unwinding inequitable and impractical, restoring the package but awarding the plaintiff only nominal $1 damages plus reduced attorneys’ fees. Musk ultimately received the full award.

The current recusal motion arises in yet another Tesla derivative suit before McCormick. Legal observers say granting it could signal heightened scrutiny of judicial social-media activity; denial might reinforce perceptions of an insular Delaware bench.

Broader fallout includes accelerated corporate migration out of Delaware, Musk himself moved Tesla’s incorporation to Texas after the first ruling, and renewed debate over whether the state’s specialized courts remain the gold standard for corporate governance disputes.

A decision is expected soon; whichever way it lands, the episode highlights the fragile balance between judicial independence and public confidence in high-profile litigation.
