SpaceX’s Starship prototype proceeds at breakneck pace towards hop tests
Well illustrated by recent drone photos of SpaceX’s up-and-coming Boca Chica, Texas facilities, dozens of SpaceXers and local contractors have congregated at the company’s Starship prototype work site over the last few weeks, progressing it from an empty tent and a collection of parts to a handful of large assemblies for what appears to be the first full-scale Starship hopper.
Much like Falcon 9’s Grasshopper and F9R (Reusable) hop test articles, this ungainly Starship hopper – standing an impressive 9m (29.5 ft) wide and ~40m (131 ft) tall – appears all but guaranteed to become the first integrated BFR hardware to take flight, hopefully supporting a productive series of low-altitude hop tests from a roughly-prepared South Texas pad.

Since SpaceX CEO Elon Musk took to Twitter to provide a number of updates on and photos of the company’s dramatically refigured approach to BFR (now Starship and Super Heavy), employees and local contractors have been working almost around the clock to keep building the first full-scale, integrated Starship test article. To be dedicated to low-speed, low-altitude hop tests, Starhopper has been a spectacle and scandal from the start thanks to an unshakable visual aesthetic reminiscent of 1950s science fiction or an elaborate and slow-burning April Fool’s prank.

As of now, several dozen tweets and tweet replies from Musk in just the last week offer extensive support for the unorthodox new design – replacing carbon composites and an ablative heat shield for a new stainless steel alloy and liquid cooling – while also firmly indicating that the object taking shape in South Texas really is a Starship hopper that will eventually take to the skies on a pillar of Raptor engine exhaust. Those inaugural hop tests could apparently begin as early as March or April 2019. Given Musk’s statements, it seems that this highly unusual Starship hop test program simply cannot be judged accurately by its cover, at least not easily.
Even for SpaceX, building an aerospace-grade prototype of a massive orbital spaceship outdoors – adjacent to soggy Texan marshland and Gulf of Mexico sea spray, no less – is utterly and completely unexpected, especially in an industry where rocket hardware is routinely fabricated indoors, if not in medical-grade clean rooms. The most likely explanation here is that we are seeing something more akin to the aeroshell or cocoon of a Starship hopper, with a huge amount of thought and debate ultimately landing on this oddity as the fastest, most affordable, and most data-rich path forward for full-scale BFR testing.

- A lifting sling is seen here attached to Starhopper’s bottom half prior to its first lift and move. (NASASpaceflight /u/bocachicagal)
- Before the move… (NASASpaceflight /u/bocachicagal)
- And after the move. (NASASpaceflight /u/bocachicagal)
- The leftmost mockup was stitched together from NASASpaceflight user bocachicagal’s on-site photos by Thomas Lacroix. The TL;DR of this is that Starhopper appears to be a solid three-quarters the height of a full 2018 BFS. (SpaceX, NASASpaceflight, Thomas Lacroix)
In this speculative instance, the sensitive liquid methane and liquid oxygen propellant tanks – as well as Starhopper’s triple-Raptor thrust structure and spaghetti plumbing – would be fabricated in SpaceX’s Hawthorne, CA factory or McGregor, TX test facilities before being shipped to Boca Chica for integration with the large structures already in work there. Those Raptors, propellant tanks, and a general program of fit-and-finish optimizations are next on the list of significant Starhopper-related events expected to occur within the next several months.
The latter task has already begun, showing up in the form of sheet metal refinement by way of essentially stitching together loose panel gaps between and within sheet-covered sections of Starhopper’s shiny silver nose. SpaceX workers also conducted the first move of the fully-integrated hopper’s base section, previously built and then sat atop a ready-made concrete stand that may or may not have come from a water tank design. While the move was slight, the base and nose sections are now roughly side-by-side along the apron of SpaceX’s temporary tent, where a third Starhopper hull segment is being built up.
2019 is going to be wild and March/April simply cannot come soon enough.

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.
