SpaceX static fires Crew-4’s Falcon 9 rocket as Axiom-1 return delay grows

(NASA)

SpaceX has successfully static fired a Falcon 9 rocket scheduled to launch another batch of NASA and ESA astronauts after the crew “completed a full rehearsal of launch day activities.”

However, poor weather and strict operational limits have prevented a separate group of private astronauts known as Axiom-1 from boarding a different Crew Dragon and returning to Earth as planned, delaying Crew-4 from April 23rd to no earlier than (NET) April 26th.

In a twist of fate that can be partially blamed on SpaceX, the ISS only has two docking ports (parking spots) capable of receiving Crew Dragon. NASA technically contracted Boeing to build three such ports but the first was destroyed when Falcon 9 failed catastrophically while attempting to launch Cargo Dragon’s CRS-7 space station resupply mission in June 2015. For unknown reasons, close to seven years later, NASA still hasn’t so much as attempted to build or launch a replacement docking adapter. As a result, most NASA cargo or crew missions have become more sensitive to the delays of other spacecraft and missions as NASA and its providers attempt to juggle a packed manifest with just two parking spots.

The lack of a third docking port and constraints on the use of one of the two remaining ports has forced NASA to repeatedly undock and redock Crew Dragons to set the stage for new arrivals and also limits the number of launch opportunities available to certain crew and cargo missions. Now, following the start of a series of Axiom Space Crew Dragon missions carrying private astronauts to the space station, NASA has yet another class of visiting vehicle to plan around.

Somewhat unsurprisingly, the close proximity of Axiom-1 and Crew-4, the presence of just two docking ports, and Crew Dragon’s fairly strict operational limits have combined to create added pressure and cause a mess of delays. Following Axiom-1’s April 8th launch, the Ax-1 Crew Dragon joined Crew-3’s Crew Dragon at the International Space Station (ISS).

To ensure a continuous US/European presence aboard the station amid Russian threats against the outpost it co-operates with NASA and other international partners, Crew-3 can’t (or shouldn’t) leave until Crew-4 arrives. Crew-4 thus can’t launch until Axiom-1 departs and frees up a docking port. Originally planned to spend around 10 days in space after their April 8th launch, the Axiom-1 crew is still aboard the ISS 12 days later after concerns about safe recovery weather have repeatedly delayed their departure. Only late on April 20th did NASA, SpaceX, and Axiom settle on a new undocking date for Ax-1, slipping from the latest target of April 20th to no earlier than 8:35 pm EDT (00:35 UTC) on April 23rd with a splashdown now on April 24th. As a result, Crew-4 has been delayed to April 26th – 11 days after the original April 15th target.

It’s unclear what particular weather concerns caused such a delay; if this is a “perfect storm” event and just a matter of bad luck; or if this situation was made worse (or possible) by apparent Crew Dragon recovery restrictions that require extremely calm seas. Regardless, it’s hard to imagine that NASA and SpaceX will attempt another private space station mission so close to an operational Crew launch after the challenges and close to two weeks of delays Axiom-1 has caused Crew-4.

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.

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 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.
