SpaceX Inspiration4 astronaut shares behind-the-scenes look at largest space window’s ‘first light’
SpaceX Inspiration4 astronaut Sian Proctor has shared the first behind-the-scenes look at what it was like for the world’s first all-private astronaut crew to witness the largest window ever flown in space for the first time.
In front of the camera: Hayley Arceneaux, now the youngest American astronaut in history and the first person ever to fly in space (or orbit) with an internal prosthetic. The mission: Inspiration4, a philanthropic creation of billionaire and CEO Jared Isaacman heavily focused on raising money (and awareness) for St. Jude’s Children’s Hospital and the fight against childhood cancer. While, as many an internet-goer will be more than eager to point out, Isaacman could have technically donated ~10% – not ~5% – of his net worth and been done with it, he instead decided to commit $100M to St. Jude’s and shepherd the world’s first all-private crewed orbital spaceflight into existence.
Private orbital spaceflight is not unique – seven other paying customers have flown to orbit and back in the 21st century. What Jared conceived of, however, is. Instead of a rather less inspirational mishmash of anyone rich enough to pay ~$20-40M for a seat, Isaacman chose to invite three relatively ordinary people along for the ride and even raffled one of the three ‘tickets’ to any American willing to donate $10 or more to the fight against childhood cancer. A step further, thanks to an excellent and transparent social media presence, millions of people from around the world got to follow the mission’s progress, watch a large portion of it live, and generally be awed by an important step forward for spaceflight and inspired by one of the most simultaneously eclectic and ordinary astronaut crew of all time.
More to the point, millions of people (or at least hundreds of thousands, for now) wouldn’t have gotten to vicariously experience the sheer joy of the first orbital cancer survivor experiencing the largest, most uninterrupted window ever flown in space for the first time. Officially known as the ‘cupola,’ SpaceX conceived of, designed, built, qualified, and flew the massive dome window in less than a year from start to finish.
Measuring around 1.2m (3.9 ft) wide and around 0.8-1m (2.5-3.2 ft) wide on the inside, Inspiration4’s cupola might offer less internal volume than NASA’s decade-old International Space Station cupola, but it makes up for the tighter space with the largest seamless window ever flown in space. Likely made out of several layers of acrylic domes not dissimilar to the ‘bubbles’ one might come across at aquariums, the innermost ‘layer’ of Dragon’s cupola carries an odd brownish hue but the glass (technically plastic) is still almost completely transparent and has no ‘frame’ or interruptions save for where it attaches to the spacecraft itself.
Thankfully, by all appearances, that brownish hue – perhaps some kind of optical coating or a tint to reduce glare – isn’t easily discernable from the inside looking out. Instead, the uninterrupted window practically melts away into a crystal-clear nothing, offering what has to be one of the best views available in space.
Given that SpaceX reportedly turned Dragon’s cupola from idea to reality in the matter of a single year and for a single customer, it’s difficult to imagine what additional upgrades could be realized on future Dragon spacecraft. Already, a senior SpaceX director says that the company is seriously considering building one or several new Dragons solely for private astronaut launches after receiving a massive uptick in demand for tickets to orbit. Even before Inspiration4 had splashed down, CEO Elon Musk promised that future flights would offer in-flight internet and hot food with the addition of a small oven/heater and a connection to the company’s own Starlink satellite constellation.
If SpaceX were to build an entirely new Dragon just for private free-flyer launches, it could potentially implement significant design changes as long as they didn’t appreciably lower safety. Given that an exclusively free-flying Dragon would never need to worry about docking in orbit, SpaceX might even be able to tweak the nosecone and make the cupola wider and taller. The possibilities may be far from endless but the fact that SpaceX would consider a modification as extreme as the cupola that flew on Inspiration4 in the first place suggests that the company is quite a lot more confident – and more willing to make big changes – than one might have previously guessed.

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.
