SpaceX’s first orbital Starship begins assembly as steel heat shield passes tests
SpaceX CEO Elon Musk says that the company’s South Texas workforce has already begun to fabricate the first orbital-class Starship prototype, while Hawthorne engineers and technicians are in the midst of performing small-scale testing of the vehicle’s unprecedented stainless steel heat shield.
To be assembled out of hexagonal tiles of (presumably) stainless steel, Starship’s metallic heat shield will be one of the most crucial aspects of the orbital spacecraft, particularly with respect to ensuring that it’s extraordinarily easy to reuse. To survive extreme interplanetary-velocity reentry conditions at Mars, Earth, and beyond and remain in a functional, flight-ready condition after landing, SpaceX will need to implement the world’s first orbital-class, large-scale metallic heat shield with an immature technology known as transpirational cooling.
By quite literally drilling tiny holes (pores) into heat shield plates at the hottest parts of Starship’s hull, transpirational cooling effectively allows a large portion of the heat of reentry to be wicked away by the flash evaporation of a liquid, typically water. For SpaceX’s Starship, it’s likely that the coolant of choice would be either liquid water or liquid methane, the former of which offers better cooling per unit of mass at the cost of added plumbing complexity and spaceship mass, while the latter would make use of the same propellant fueling the ship at the cost of worse cooling per unit of mass. Either way, SpaceX will be heading into unproven territory, demanding extensive ground and flight testing to first ensure that the concept is truly viable and then to verify that it can be made as reliable and reusable as it simply has to be.
Tests like those shown on March 17th by Musk indicate that SpaceX is indeed deep into the process of extensive and often destructive testing, something the company has proven to be exceptionally good at. It’s unclear if the above test of Starship’s hexagonal heat shield tiles – likely made out of a variant of 300-series stainless steel – involved tiles with active or passive cooling, but Musk suggested that the hot-spots created with spin-forming torches reached temperatures as high as 1650 Kelvin (2500ºF/1400ºC. Unlike the ablative heat shields SpaceX is familiar with building and operating through its Crew and Cargo Dragon spacecraft, a stainless steel heat shield would be expected to almost entirely resist erosion (i.e. ablation) during extremely high-velocity reentries of at least 12-14 km/s (~31,000 mph, Mach 40+).

Meanwhile, Musk also confirmed that SpaceX has decided to skip constructing a replacement nosecone/fairing for Starhopper, a functional Starship prototype that will be used to conduct extremely short hop tests like Falcon 9’s development-era Grasshopper and F9R test articles. Over the last several weeks, SpaceX technicians have been rapidly assembling what was initially assumed to be the replacement fairing Musk had previously suggested would be built. Instead, the duo of stainless steel barrel sections – relying on steel much thinner than the heavy-duty stuff used to build Starhopper – are apparently the beginnings of the first orbital-class Starship prototype, said by Musk to be aiming for flight-readiness as early as June 2019 around two months ago.
While still an extraordinarily ambitious target for a vehicle that has yet to conduct any integrated hops or flight-tests in any form, the fact that SpaceX is began the process of building the first orbital Starship in late February could actually give the company’s engineers and technicians a fighting chance to complete Starhopper testing and Starship assembly over the next 90-100 days.
If stacked atop each other, the two new steel sections in work would likely stretch a solid 20-30 meters (65-100 ft) tall. Meanwhile, the first orbital-grade tank domes and/or conical nose section is also in the process of being welded together out of smaller segments, already fast approaching something ready to be installed inside the steel barrel sections.

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.

Starbase after dark: Musk’s latest photo captures a Spaceport on the brink of history
SpaceX’s Starbase city in Boca Chica, Texas is rapidly transforming the southern tip of the Lone Star State into one of the most ambitious launch complexes in history.
A striking nighttime photograph of SpaceX’s Starbase facility in Boca Chica, Texas, shared recently by Elon Musk on X, offers a dramatic glimpse of an operation that is rapidly transforming the southern tip of the Lone Star State into one of the most ambitious launch complexes in history.
The most immediately visible change in the photo is the presence of two fully erected Starship launch towers dominating the coastal skyline. The second orbital launch pad, known as Pad B, now features its fully erected tower, OLIT-3, which stands approximately 474 feet tall and incorporates an integrated water-cooled flame trench designed to minimize damage and reduce turnaround time between launches. The dual-tower silhouette against the night sky signals a decisive shift from experimental testing facility to high-cadence launch operations.

Back at Starbase, Pad 2 is approaching hardware completion, with upgraded chopstick arms, a new chilldown vent system, and all 20 hold-down arms now fitted with protective doors to shield them from the intense exhaust of up to 33 Raptor 3 engines, according to a deeper dive by NASASpaceFlight.
SpaceX has also received approval to nearly double the footprint of the Starbase launch site, with groundwork already underway to add LNG liquefaction plants, expanded propellant storage, and additional ground support infrastructure.
The photo also carries a milestone civic dimension. Starbase officially became a Texas city in May 2025 after a community vote, with SpaceX employees elected as mayor and commissioners of the newly incorporated municipality. That legal status streamlines launch approvals and gives SpaceX direct control over local infrastructure decisions.
The FAA has approved an increase in launches from Starbase in Texas from five to twenty-five per year, clearing the runway for the kind of flight frequency needed to fulfill Starship’s ultimate mission of ferrying cargo and crew to the Moon, servicing the Department of Defense, deploying next-generation Starlink satellites, and eventually establishing Elon Musk’s long sought after goal of a self-sustaining human presence on Mars.
Seen from above in the dark, Starbase looks less like a test site and more like a spaceport.

Elon Musk shares updated Starship V3 maiden launch target date
The comment was posted on Musk’s official account on social media platform X.
SpaceX CEO Elon Musk shared a brief Starship V3 update in a post on social media platform X, stating the next launch attempt of the spacecraft could take place in about four weeks.
The comment was posted on Musk’s official account on social media platform X.
Musk’s update suggests that Starship Flight 12 could target a launch around early April, though the schedule will depend on several remaining milestones at SpaceX’s Starbase launch facility in Texas.
Among the key steps is testing and certification of the site’s new launch tower, launch mount, and tank farm systems. These upgrades will support the next generation of Starship vehicles.
Booster 19 is expected to roll to the launch site and be placed on the launch mount before returning to the production facility to receive its 33 Raptor engines. The booster would then return for a static fire test, which could mark the first time a Super Heavy booster equipped with Raptor V3 engines is fired on the pad.
Ship 39 is expected to undergo a similar preparation process. The vehicle will likely return to the production site to receive its six engines before heading to Massey’s test site for static fire testing.
Once both stages are prepared, the booster and ship will roll out to the launch site for the first full stack of a V3 Super Heavy and V3 Starship. A full wet dress rehearsal is expected to follow before any launch attempt.
Elon Musk has previously shared how SpaceX plans to eventually recover Starship’s upper stage using the launch tower’s robotic arms. Musk noted that the company will only attempt to catch the Starship spacecraft after two successful soft landings in the ocean. The approach is intended to reduce risk before attempting a recovery over land.
“Should note that SpaceX will only try to catch the ship with the tower after two perfect soft landings in the ocean. The risk of the ship breaking up over land needs to be very low,” Musk wrote in a post on X.
Such a milestone would represent a major step toward the full reuse of the Starship system, which remains a central goal for SpaceX’s long-term launch strategy.
