SpaceX’s Starship, Starhopper prototypes continue slow and steady progress

Published

on

The last few weeks of SpaceX’s work on Starship and Starhopper prototypes has been marked by less visible progress relative to the past few months. The changes that are visible, however, confirm that its Boca Chica engineers are working around the clock to complete the first orbital Starship prototype.

At the same time, it appears that SpaceX’s South Texas facilities are preparing for a rapid period of expansion and build-up. New work around the ad-hoc Starhopper pad has recently begun, while construction of a second concrete jig for concurrent prototype fabrication and what will likely be a more permanent hangar and control facility are also ramping up. Things have been quiet news-wise for SpaceX’s McGregor and Hawthorne facilities but there is reason to believe that Raptor production and testing is going smoothly.

Starship Alpha

The most obvious visible progress made in April is centers around SpaceX’s first orbital Starship prototype, soon to begin its third month of active construction. As of mid-March, the shells of two large steel barrel sections – together about 18 m (60 ft) tall – were fully erected at the build site, with a handful of other sections in various states of welding. The height of those two cylinders has remained unchanged since then but it’s safe to assume that a ton of work has been going on inside them, invisible to anyone viewing from public perspectives since drones were effectively banned in March. In other words, the two pieces – most likely the barrel sections of Starship’s liquid methane and liquid oxygen (LOX) tanks – are likely being carefully transformed into actual propellant tanks.

There is also a good reason for their height differential: the larger (LOX) section is almost exactly a third larger than the small section (methane) in part because of the physical reality that Starship will need almost exactly 33% more LOX than methane by volume. Large propellant tanks – particularly those meant for cryogenic fluids and spaceflight applications – are often quite complex, with the vast majority of that complexity happening under the hood. The above render was made while SpaceX was still planning on carbon fiber tanks and also appears to be significantly simplified, but it still offers a small look at some of that complexity.

Aside from successfully completing thousands of welds throughout the assembly, a lot of the effort of building an advanced tank is put into plumbing – both internal and external – needed to load, unload, pressurize, depressurize, and generally manage cryogenic (i.e. super cold) liquid propellant. SpaceX decided to utilize a partial balloon tank design to keep the steel skins of its stainless steel Starship and Super Heavy as thin as possible, adding yet another level of internal work due to the need for stringers and longerons on top of baffles and hardware to mount COPVs or header tanks.

Adding further complexity to the internal structure of Starship is the presence of major aerodynamic surfaces and landing legs, both of which will need to survive extreme stresses if they are to function as intended. Those structures must be aerodynamically streamlined and attach to the outside of Starship’s hull, likely requiring significant structural reinforcements both inside the spacecraft’s nose and rearmost propellant tank.

Super Heavy?

SpaceX began construction of a second concrete fabrication jig just a handful of days ago. Effectively a copy of a jig occupied with the larger of the two barrel sections of the orbital Starship prototype, the simple structure acts as a mount and includes a large door that allows scissor lifts to get inside the steel structure. The new jig is being built directly adjacent to Starship’s smaller barrel section, suggesting that it could simply be a way to concurrently work on both the LOX and methane tanks. Given the inherent simplicity of a concrete jig, it could also end up being used to support the simultaneous assembly and integration of the first Super Heavy booster prototype.

Back in December 2018, SpaceX CEO Elon Musk indicated that the first Super Heavy prototype would start production in “spring” (i.e. NET April 2019). Musk has also indicated that Starship and Super Heavy will be simultaneously built both in Boca Chica, Texas and Cape Canaveral, Florida. In general, SpaceX is clearly beginning another round of expansion and improvement for its Boca Chica facilities, including the new concrete jig and an entirely new building on the same plot of land.

Starhopper

Last but not least is SpaceX’s Starhopper prototype. After completing an inaugural round of multiple wet dress rehearsals (WDRs) and two Raptor static fires/hops, SpaceX technicians removed the vehicle’s lone Raptor engine on April 8th. Starhopper has remained more or less inactive in the last two weeks, aside from some work going on inside the vehicle (per the open access hatch).

Without a Raptor engine, there is admittedly not a whole lot that SpaceX can do with Starhopper, aside from additional WDRs if the first handful of tests were not enough. Instead, some minor work has been going on around the Hopper’s ad hoc pad, mainly taking the appearance of dirtmoving. Without aerial views, its hard to tell what exactly is taking shape, but it’s safe to say that Starhopper is simply waiting for additional Raptors to be produced, tested, and delivered to Boca Chica. Once more Raptors are ready, it’s understood that SpaceX will move into multi-engine (likely 3+) hop tests, perhaps loosing Starhopper from its tethers.

SpaceX adjusts Starship Flight 13 test launch target date once again

Published

on

Credit: SpaceX

SpaceX has updated its target for the thirteenth integrated flight test of Starship, aiming for as early as Thursday, July 23. The 90-minute launch window opens at 5:45 p.m. CT from the company’s Starbase facility in South Texas.

The target flight was initially rescheduled for today, but SpaceX pushed it back again.

This latest adjustment follows an aborted attempt earlier in the week and reflects the iterative, rapid-development approach that has defined the Starship program. With the vehicle already stacked and ground teams making final preparations, the mission represents another step toward proving the full reusability of the world’s most powerful rocket system.

The original launch attempt on July 16 was scrubbed at T-0 when several Raptor engines on the Super Heavy booster failed to ignite properly. The automatic abort system triggered just as the engines began their startup sequence, preventing liftoff.

SpaceX CEO Elon Musk confirmed that some engines did not start as expected, prompting the decision to replace two Raptors on Booster 20 to ensure reliability. The issue occurred despite a successful full-duration static fire earlier, highlighting the complexities of coordinating 33 engines under flight conditions.

This cautious approach underscores SpaceX’s commitment to safety amid an aggressive test cadence.

SpaceX comes with a slew of changes for Starship Flight 13

Flight 13 builds directly on the lessons from Flight 12 in May 2026. The Super Heavy booster’s primary goals include a successful liftoff, ascent, stage separation, boostback burn, and controlled splashdown in the Gulf of America.

Hardware and software modifications address the off-nominal flip and boostback burn problems from the prior flight, where propellant slosh and engine relight issues led to an uncontrolled impact.

For the Starship upper stage, objectives include deploying 20 operational Starlink V3 satellites, the first real payload of this type, performing a single Raptor engine relight in space, and executing a controlled entry, descent, and splashdown in the Indian Ocean. Propulsion upgrades aim to improve engine-out capability after one vacuum Raptor was lost on Flight 12.

Additional test elements focus on heat shield performance. Six satellites carry cameras to image the tiles during flight, while white-painted tiles and upgraded attachments on flaps and the aft skirt will gather data for future reusability.

The FAA completed its mishap investigation into Flight 12 earlier this month, clearing the regulatory path.

This suborbital mission, the second with V3 vehicles, advances Starship toward operational missions, including potential crewed flights and support for NASA’s Artemis program. Success would mark significant progress in rapid reusability and satellite deployment from the massive system.

Elon Musk debunks $52 billion SpaceX-NVIDIA GPU deal

Elon Musk dismissed reports claiming SpaceX had placed a massive order for NVIDIA GPUs worth $52 billion. The denial came hours after Taiwanese media, citing unnamed industry sources, reported that SpaceX planned to acquire approximately 13,000 AI server racks, equating to roughly 1 million GB300 GPUs, from Foxconn.

Each rack was estimated at around $4 million, with deliveries potentially starting in late 2025.

The story suggested this would mark SpaceX’s first major foray into Foxconn-manufactured NVIDIA hardware, breaking from suppliers like Supermicro and Dell. Musk responded bluntly on X:

Despite the denial, the rumored scale aligns with SpaceX’s explosive growth in AI infrastructure. NVIDIA’s GB300 (successor to the GB200 NVL) racks deliver unprecedented performance for large-scale training and inference. A $52 billion commitment would dwarf most corporate AI budgets and provide the compute muscle needed for frontier models.

SpaceX already operates gigawatt-scale terrestrial clusters like Colossus in Memphis, Tennessee, and has monetized them aggressively through leasing deals.

SpaceX’s newest Starmind will make earth data centers obsolete

Major customers include Anthropic (paying ~$1.25 billion monthly for 220,000+ GPUs), Google (~$920 million monthly for 110,000 GPUs), and Reflection AI. These arrangements are projected to generate tens of billions in annual revenue, far outpacing traditional SpaceX businesses.

Such an investment would fuel internal AI efforts, particularly Grok models under the integrated SpaceXAI division, while supporting ambitious orbital data center plans. SpaceX envisions launching thousands of AI-optimized satellites powered by solar energy and cooled in space, bypassing terrestrial power and land constraints.

This “Starmind” constellation could position the company as a leader in space-based computing.

SpaceX as an Emerging AI Powerhouse

Once primarily known for reusable rockets and Starlink satellite internet, SpaceX has transformed into a multifaceted AI player.

The 2026 acquisition of xAI integrated Grok development directly into the company. Starlink’s low-latency global network complements massive compute clusters, enabling efficient data flow for training and serving AI models.

Musk has long argued that AI scaling demands solutions beyond Earth, citing things like real estate and electricity limits on the ground.

While the Foxconn deal may not be in the cards, SpaceX’s trajectory is continuing on the path of blending aerospace engineering with hyperscale AI to dominate both launches and intelligence infrastructure.

SpaceX has announced a new target date for the thirteenth test flight of Starship: Monday, July 20, with the launch window opening at 6:45 p.m ET/5:45 p.m. CT.

This is the first rescheduling attempt of Starship’s 13th test flight. It was set to launch last night, but SpaceX scrubbed the launch attempt.

CEO Elon Musk revealed that some of the engines on Starship did not start, which automatically triggers a launch abort. Two of the Raptor engines will be removed and replaced.

SpaceX officially announced the new launch window this morning.

Starship’s 13th test launch comes with a few new objectives, but SpaceX does not plan to attempt a catch of the booster, which it has done several times in the past.

For Starship’s Upper Stage, there are some adjustments to ensure engine reusability that will be assessed during the ascent, and 20 operational Starlink V3 satellites are also set to make their way into space. SpaceX also plans to attempt an in-space relight of a single Raptor engine, which is a critical demonstration for future orbital deorbit, refueling, and deep space maneuvers.

Ultimately, it will splash down in the Indian Ocean.

The continuous tests help SpaceX advance the Starship program toward eventual full reusability, operational Starlink V3 deployment, and future missions, which include NASA’s Artemis program.
