SpaceX begins stacking Florida Starship launch tower
SpaceX has begun stacking Starship’s first Florida launch tower.
Less than half a year after the company restarted work on a Starship launch pad located just a few hundred feet away from existing Falcon launch facilities at NASA’s Kennedy Space Center (KSC) LC-39A pad, a massive new launch tower has begun to take shape. Once it reaches its final height, that tower will become the second tallest rocket-related structure (excluding lightning towers) on the East Coast, only beaten by NASA’s iconic Vehicle Assembly Building (VAB).
It could reach that height far sooner than later.
For Starship’s Pad 39A facilities, SpaceX faces the unique challenge of organizing a major construction operation at one of the busiest and most important active launch sites in the US. In just the first half of 2022, LC-39A is on track to support 10 Falcon 9 launches, imposing unique constraints on adjacent Starship pad construction. In a partial response to those challenges, as previously discussed on Teslarati, SpaceX has taken lessons learned from Starbase, Texas and optimized the assembly process of a number of pad components to limit the amount of work that will need to be done at the pad itself.
For the first launch tower, SpaceX and its contractors moved exceptionally quickly and took just over three months after work on the first prefabricated section began to stack the structure to its full height of ~146 meters (~480 ft). Each of the nine sections was essentially bare, however, reducing the amount of pre-stack work but drastically complicating and increasing the amount of post-stack work required to turn the tower into something useful. For Florida’s first Starship launch tower, SpaceX has spent more than three months assembling and meticulously outfitting the first six of nine prefabricated tower sections before the first stack.
The sections SpaceX began stacking on June 21st already have a variety of railings, elevator shafts, doorways, walkways, hardpoints, plumbing, and more preinstalled. While each section and all abbreviated plumbing and hardware will need to be connected after each stack, that process should be far easier and faster than the methods SpaceX used in South Texas. Offsite, SpaceX is also making excellent progress assembing the pad’s donut-like orbital launch mount and parts of the three giant arms that will eventually attach to Starship’s first Florida launch tower – two for lifting and catching rockets and a third for stabilizing and fueling Starship.
Much like the tower segments, there’s a good chance that those other Floridan components will be closer to completion than their Texas siblings were when they eventually head to the launch pad for installation. Additionally, if SpaceX’s experience in Texas is representative, Starship’s first Florida launch tower could reach its full height just a few months from now.
For the tower to be truly complete, SpaceX will need to finish and install three arms, and connect one of those arms to ground supplies of Starship gases and propellant located at Pad 39A. Because 39A has never needed methane, Starship’s fuel of choice, that step will also require the installation and activation of a new tank farm and plumbing capable of storing, rapidly ‘subcooling,’ and distributing at least a thousand tons (~2.2M lb) of liquid methane (LCH4). Starbase Florida is making great progress but a large amount of work still stands between SpaceX and launch readiness.

Tesla Semi expands pilot program to Texas logistics firm: here’s what they said
Mone said the Tesla Semi it put into its fleet for this test recorded 1.64 kWh per mile efficiency, beating Tesla’s official 1.7 kWh per mile target and delivering a massive leap over conventional diesel trucks.
Tesla has expanded its Semi pilot program to a new region, as it has made it to Texas to be tested by logistics from Mone Transport. With the Semi entering production this year, Tesla is getting even more valuable data regarding the vehicle and its efficiency, which will help companies cut expenditures.
Mone Transport operates in Texas and on the Southern border, and it specializes in cross-border U.S.-Mexico freight operations. After completing some rigorous testing, Mone shared public results, which stand out when compared to efficiency metrics offered by diesel vehicles.
“Mone Transport recently had the opportunity to put the Tesla Semi to the test, and we’re thrilled with the results! Over 4,700 miles of operations at 1.64 kWh/mile in our Texas operation. We’re committed to providing zero-emission transportation to our customers!” the company said in a post on X.

Mone said the Tesla Semi it put into its fleet for this test recorded 1.64 kWh per mile efficiency, beating Tesla’s official 1.7 kWh per mile target and delivering a massive leap over conventional diesel trucks.
Comparable Class 8 diesel semis, typically achieving 6-7 miles per gallon, consume roughly 5.5 kWh per mile in energy-equivalent terms, meaning the Semi uses three to four times less energy while also producing zero tailpipe emissions.
Tesla Semi undergoes major redesign as dedicated factory preps for deliveries
The performance of the Tesla Semi in Mone Transport’s testing aligns with data from other participants in the pilot program. ArcBest’s ABF Freight Division logged 4,494 miles over three weeks in 2025, averaging 1.55 kWh per mile across varied routes, including a grueling 7,200-foot Donner Pass climb. The truck “generally matched the performance of its diesel counterparts,” the carrier said.
PepsiCo, which operates the largest known Semi fleet, recorded 1.7 kWh per mile in North American Council for Freight Efficiency testing. Additional pilots showed similar gains: DHL hit 1.72 kWh per mile, and Saia achieved 1.73 kWh per mile.
These metrics underscore the Semi’s ability to slash operating costs through superior efficiency, lower maintenance, and zero-emission operation. As charging infrastructure scales and production ramps toward 2026 targets, participants like Mone Transport are proving electric semis can seamlessly integrate into freight networks, accelerating the industry’s shift to sustainable, high-performance trucking.
Tesla continues to prep for a more widespread presence of the Semi in the coming months as it recently launched the first public Semi Megacharger site in Los Angeles. It is working on building out infrastructure for regional runs on the West Coast initially, with plans to expand this to the other end of the country in the coming years.

SpaceX weighs Nasdaq listing as company explores early index entry: report
The company is reportedly seeking early inclusion in the Nasdaq-100 index.
Elon Musk’s SpaceX is reportedly leaning toward listing its shares on the Nasdaq for a potential initial public offering (IPO) that could become the largest in history.
As per a recent report, the company is reportedly seeking early inclusion in the Nasdaq-100 index. The update was reported by Reuters, citing people familiar with the matter.
According to the publication, SpaceX is considering Nasdaq as the venue for its eventual IPO, though the New York Stock Exchange is also competing for the listing. Neither exchange has reportedly been informed of a final decision.
Reuters has previously reported that SpaceX could pursue an IPO as early as June, though the company’s plans could still change.
One of the publication’s sources also suggested that SpaceX is targeting a valuation of about $1.75 trillion for its IPO. At that level, the company would rank among the largest publicly traded firms in the United States by market capitalization.
Nasdaq has proposed a rule change that could accelerate the inclusion of newly listed megacap companies into the Nasdaq-100 index.
Under the proposed “Fast Entry” rule, a newly listed company could qualify for the index in less than a month if its market capitalization ranks among the top 40 companies already included in the Nasdaq-100.
If SpaceX is successful in achieving its target valuation of $1.75 trillion, it would become the sixth-largest company by market value in the United States, at least based on recent share prices.
Newly listed companies typically have to wait up to a year before becoming eligible for major indexes such as the Nasdaq-100 or S&P 500.
Inclusion in a major index can significantly broaden a company’s shareholder base because many institutional investors purchase shares through index-tracking funds.
According to Reuters, Nasdaq’s proposed fast-track rule is partly intended to attract highly valued private companies such as SpaceX, OpenAI, and Anthropic to list on the exchange.

The Boring Company’s Prufrock-2 emerges after completing new Vegas Loop tunnel
The new tunnel measures 2.28 miles, making it the company’s longest single Vegas Loop tunnel to date.
The Boring Company announced that its Prufrock-2 tunnel boring machine (TBM) has completed another Vegas Loop tunnel in Las Vegas. The company shared the update in a post on social media platform X.
According to The Boring Company’s post, the new tunnel measures 2.28 miles, making it the company’s longest single Vegas Loop tunnel to date.
The new tunnel marks the fourth tunnel constructed near Westgate Las Vegas as the Vegas Loop network continues expanding across the city.
The Boring Company also noted that the new tunnel surpassed its previous internal record of 2.26 miles for a single Vegas Loop segment.
Construction of the tunnel involved moving roughly 68,000 cubic yards of dirt. The excavation process also used about 4.8 miles of continuous conveyor belt, powered by six motors totaling 825 horsepower.
The Boring Company’s Prufrock-series all-electric tunnel boring machines are designed to support the rapid expansion of company’s underground transportation projects, including the growing Vegas Loop network. Prufrock machines are designed for reusability, thanks in no small part to their capability to be deployed and retrieved easily through their “porposing” feature.
The Vegas Loop, specifically the Las Vegas Convention Center (LVCC) Loop segment, has already been used during major events. Most recently, the LVCC Loop supported the 2026 CONEXPO-CON/AGG construction trade show, which was held from March 3-7, 2026.
As per The Boring Company, the LVCC Loop transported roughly 82,000 passengers across the convention center campus during the event’s duration.
CONEXPO-CON/AGG is one of the largest construction trade shows in North America, drawing more than 140,000 construction professionals from 128 countries this year.
The LVCC Loop forms the initial segment of the broader Vegas Loop network, which remains under active development as The Boring Company continues building new tunnels throughout the city.
