SpaceX’s second Falcon 9 Block 5 booster, core B1047, has returned once more to Port Canaveral, Florida aboard drone ship Of Course I Still Love You (OCISLY) after a successful flight-proven launch, placing commercial communications satellite Es’hail-2 into a healthy, high-energy orbit.

SpaceX’s third reuse of a Block 5 booster since the upgraded Falcon 9 version’s May 2018 debut, the November 15 launch marks the company’s 11th mission to launch on a flight-proven rocket in 2018 alone, more than 60% of the 18 missions completed thus far.

Prior to launching Es’hailsat’s Es’hail-2 satellite, Falcon 9 B1047 placed the massive ~7000 kg (15,500 lb) Telstar 19V communications satellite into orbit while also marking the second successful launch of Falcon 9’s Block 5 iteration. Nearly a new rocket, Block 5 focused on dramatically improving the reliability and reusability of the workhorse Falcon 9 rocket, ultimately translating into the total redesign and replacement of a large number of major subsystems.

The changes range from a totally new octaweb thrust structure (bolted, rather than welded, together), a clean-sweep upgrade of first and second stage avionics, new helium and nitrogen pressure vessels (COPVs), a total revamp of thermal protection for the interstage, legs, and octaweb, significantly refined Merlin 1D sea level and vacuum engines, Fairing 2.0, and much, much more. With the extensive changes brought by Block 5, SpaceX engineers strove to fully eradicate or at least cushion several unlikely but possible failure modes while also increasing the overall usable lifespan of particularly flight-critical, wear-intensive systems and components.

How many layers of soot?

Although it’s clear that some distance must still be covered before the specific goals of Block 5 can be realized, the aspiration of the design is to enable as many as 10 booster reuses with little more than thorough inspections between launches, and perhaps 100 or more launches per booster with more extensive maintenance and repairs every 10 or so launches.

The first unprecedented step in that direction – for Falcon 9 Block 5, at least – will be the third launch of a specific booster, a feat SpaceX was not willing to attempt before Block 5’s introduction. That milestone third launch was actually meant to occur on Monday, November 19 but has since been delayed to give SpaceX time to perform additional preflight inspections of Falcon 9, be it the twice-flown booster, the upper stage, the payload fairing, or all of the above.

Given just how critical a step the launch will be for SpaceX’s long-term goal of fielding rockets with aircraft-like reusability, caution is particularly key in this case, as any partial or total failure will almost instantly soil multi-flight Falcon 9 boosters in the eyes of a number of launch customers, potentially leading customers to request launches on boosters that have previously flown less than twice. Even then, a 5-7 day delay can be extremely unsavory for many customers, as time is very frequently money for satellite operators – a satellite on the ground is essentially a black hole that devours capital and generates zero revenue, sort of like a nuclear reactor that hasn’t been connected to the grid.

B1047’s successful return to port after a second operational launch will serve as another valuable wealth of data that can be used to further optimize SpaceX’s understanding of Falcon 9 Block 5 and its capabilities.

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 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.

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.
