SpaceX’s Florida Starship hits growth spurt as Texas Starship begins bulkhead installation

In the last week alone, SpaceX’s twin orbital Starship prototypes have made some truly jaw-dropping progress. Onlookers have witnessed Florida’s Starship push through a rapid growth spurt, while the company’s Texas team has begun to install propellant tank bulkheads and work on a triple-Raptor thrust structure.

Meanwhile, SpaceX CEO Elon Musk has suggested that one or both of the orbital-class Starship prototypes could be “almost ready to fly” by August 24th, the date of the CEO’s next official update on Starship (formerly BFR and ITS). Although the actual challenge of building a massive, orbital-class launch vehicle is far subtler than the visible steelwork needed to build its primary structure and pressure vessels, the veritable leaps forward made in both Texas and Florida in the last 7-10 days are extremely encouraging signs.

Bulkheads galore

Starting off in Boca Chica, Texas, SpaceX’s team of engineers and technicians have been simultaneously handling Starhopper’s first untethered flight test (completed on July 25th) and building the facility’s orbital-class Starship prototype. Most significantly, after a few days of preparation, what is likely the Texas Starship’s first bulkhead was lowered inside its ~25m-tall (80 ft) barrel section, composed of the spacecraft’s propulsion section and propellant tanks.

Pictured below, technicians carefully craned the first 9m (30ft) diameter dome inside the Texas Starship on July 30th. Based on its orientation and the recent arrival of a similar dome, this particular bulkhead is almost certainly the bottom dome and first of three to be installed. It will thus serve as the bottom of the Texas Starship’s liquid methane propellant tank, as well as a significant structural member of the rocket’s thrust structure, needed to safely transfer the force of 3-6 Raptors to the rest of Starship.

SpaceX Texas also accepted delivery of the first multi-engine Starship thrust structure, featuring three obvious spots for three Raptors, meshing with Musk’s August 3rd statement that “Starship Mk1” would feature three of the engines.

11 meters, 5 days

Meanwhile, at SpaceX’s similar Florida Starship facility, the similar-but-not-quite-identical spacecraft has experienced even more rapid growth. Over the course of perhaps 4 or 5 days, technicians installed a full six new rings worth of steel segments on the vehicle’s tank section, separated from the curved nose section just like SpaceX’s Texas Starship. With an individual height of almost exactly six feet (~1.8m), the six new rings combined to add more than 10.5m to the Florida Starship’s relative height in just a few days. Combined, the nose and barrel sections would likely reach a height of 45-50m (145-165 ft), roughly 10-15% shy of full height (55m).

No fewer than 7 additional rings are visible in various stages of work (c. Aug. 4) across the Cocoa campus after the recent growth spurt.

Of note, a bulkhead visible between the Florida Starship’s barrel and nose sections in mid-July disappeared around the third week of the month, a strong indicator that SpaceX’s Florida campus actually beat Texas to their first Starship tank dome installation by as much as ~10 days. The fact that SpaceX is effectively racing itself to build the first flight-ready orbital-class Starship is deeply entertaining, but it also serves as an extremely unique example of the application of A/B testing (commonly used in software dev.) to spacecraft assembly.

Per Musk, the goal is not meant to be cutthroat (i.e. two groups enter, one group leaves) and both groups (Boca Chica and Cocoa) were said to be actively cooperating and sharing important lessons learned. Still, the geographically separated groups are visibly utilizing different methods, facilities, materials, and approaches. In effect, SpaceX has encouraged two of its own groups to duel (albeit in a semi-friendly manner) as a deeply unorthodox method of getting Starship to operational readiness as fast as physically possible.

Although Musk did partially contradict himself on August 3rd, implying that the first orbital Starship prototype(s) could be “almost ready for flight” by late August, the SpaceX CEO stated on July 19th that both Florida and Texas Starships could be ready for their first (suborbital) flights in “2 to 3 months”, or September/October. The first orbital Starship launch would follow as few as 2-3 months after that (or those) first flight milestones.

In short, Musk’s official August 24th Starship presentation is likely to be downright jaw-dropping. Stay tuned!

SpaceX Starship Flight 13 faces wrath of the Texas skies

SpaceX pushed Starship Flight 13 to Friday, blaming weather instead of the previous engine issues.

Published

By

SpaceX called off Thursday’s launch attempt of Starship Flight 13, pushing the mission to Friday because of weather tied to Tropical Storm Bertha. The company confirmed the delay on X, noting “Now targeting Friday, July 24 for Starship’s thirteenth flight test, due to weather. A key objective for the flight test is to get clear imagery from the ground of Starship’s heatshield as it flies at a higher dynamic pressure during ascent, which won’t be possible with today’s weather conditions.”

This is the second delay for Flight 13 in two weeks. SpaceX first tried to launch the mission on July 16, but the countdown ended in an automated abort at T-0 when four of Super Heavy Booster 20’s 33 Raptor engines failed to ignite. Musk said at the time that two Raptors would need to be removed and replaced, as Teslarati reported. The company spent the following week destacking Ship 40 and Booster 20, swapping engines, and running leak checks before restacking the vehicle on Pad 2 Wednesday night, according to Spaceflight Now’s live coverage.

Unlike the engine problem, Thursday’s delay has nothing to do with the hardware. SpaceX wants clean footage of Starship’s heat shield captured from the ground as the vehicle flies through max dynamic pressure, something the storm’s cloud cover over South Texas would not allow. The company said visibility should improve for Friday’s attempt, with the same 90 minute window opening at 5:45 p.m. CT.

Flight 13 will be the second outing for the V3 versions of Starship and Super Heavy, following their debut on Flight 12 in May. The mission carries 20 production Starlink V3 satellites, the first time SpaceX has flown operational satellites rather than mass simulators on Starship. Six of those satellites are fitted with cameras to inspect the heat shield from a different angle during ascent, giving engineers a second data source beyond the ground imagery the weather is currently blocking.

Booster 20 will attempt a boostback burn and a splashdown landing burn in the Gulf of America, while Ship 40 follows a suborbital trajectory toward a landing in the Indian Ocean. The flight plan largely mirrors Flight 12, though the booster will run a more aggressive ascent burn after max Q this time, and the ship’s heat shield includes load sensing tiles meant to measure stress at the higher dynamic pressure SpaceX is targeting.

If Friday’s attempt succeeds, Flight 13 could be the last suborbital test in the program. SpaceX is already looking to push for an orbital flight on Flight 14.

Tesla stock (NASDAQ: TSLA) endured one of its sharpest single-day declines in years on July 23, tumbling approximately 14.5 percent and closing near $320 after opening the session around $374. The drop erased more than $140 billion in market value amid heavy trading volume and left the shares at multi-week lows.

The sell-off followed the company’s second-quarter 2026 results, released the previous evening. Tesla reported record revenue of $28.2 billion, up 26 percent year over year, driven by a Q2-record 480,126 vehicle deliveries. Energy storage deployments also rose strongly.

Tesla (TSLA) Q2 2026 earnings results: miss on EPS, beat on revenue

Yet profitability disappointed sharply. Operating income fell 57 percent to $398 million, compressing the operating margin to just 1.4 percent. Non-GAAP earnings per share came in at $0.33, well below the roughly $0.53 analysts had expected. Free cash flow turned negative by $1.1 billion as capital expenditures surged 142 percent to $5.8 billion, largely tied to accelerated spending on artificial intelligence, robotics, and autonomous systems.

The losses on capex were expected, as Tesla said it would be spending heavily in 2026.

Investors also reacted to lingering uncertainty surrounding key product timelines. During the Earnings Call, management reiterated ambitions for Robotaxi deployment and the Optimus humanoid robot, but offered limited new concrete milestones, renewing questions about execution pace that have long accompanied Tesla’s ambitious roadmap.

The magnitude of the decline places it among Tesla’s more severe one-day percentage losses since its 2010 initial public offering. Historically, the two largest single-day drops (split-adjusted) remain September 8, 2020, when shares fell 21.1 percent amid broader market volatility and valuation concerns, and January 13, 2012, with a 19.3 percent plunge during the company’s early growth struggles.

Other notable declines include an 18.6 percent drop on March 16, 2020, at the onset of pandemic-related market turmoil. Thursday’s move ranks roughly ninth on the all-time list but stands out as the steepest in more than a year.

Despite the short-term pain, Tesla’s long-term trajectory has repeatedly recovered from such volatility. The latest results underscore both the strength of its core automotive and energy businesses and the near-term costs of heavy investment in next-generation technologies.

Elon Musk is not happy about this Tesla Full Self-Driving approval delay

Published

on

Elon Musk clapped back at France’s decision to withhold the approval for Tesla’s Full Self-Driving (FSD) Supervised system, projecting a clear and blunt message to French Transport Minister Phillippe Tabarot, after he publicly rejected the technology in its current form.

Tabarot outlines several concerns with Tesla Full Self-Driving in a detailed video statement, where he said, “The safety trade-offs are not yet sufficient to authorize it as it currently stands,” he said. He emphasized that FSD is not a true self-driving system and that the driver remains fully responsible.

Key issues Tabarot also brought up included allowing speeding when surrounding traffic exceeds limits and what he believes are insufficient guarantees of driver attention during complex urban maneuvers such as lane changes, intersections, and roundabouts.

While acknowledging technological progress and France’s support for autonomous innovation, Tabarot stressed that deployment must prioritize road safety. He noted ongoing technical discussions with Tesla, the Netherlands, and other European partners, with further ecosystem meetings planned for the fall.

Musk’s rebuke highlights the human cost of regulatory caution. Tesla’s latest safety reports provide compelling data supporting accelerated adoption. In the most recent 12-month period, vehicles using FSD (Supervised) recorded one major collision per approximately 5.1 million miles driven, dramatically better than the U.S. national average of one crash per 698,000 miles.

Even Tesla vehicles driven manually with active safety features outperform the average by a wide margin. These figures come from billions of real-world miles of telemetry, showing FSD vehicles involved in far fewer incidents than both manual Teslas and the broader U.S. fleet.

Critics argue Tesla’s comparisons require careful scrutiny regarding reporting thresholds and fleet demographics, yet the data consistently positions FSD as a potential lifesaver. With road fatalities remaining a leading cause of death worldwide, Musk contends that proven safer technology should not face prolonged bureaucratic hurdles.

France’s measured approach reflects the broader European regulatory caution, which many, especially Musk, have been critical of in the past. However, as autonomous systems from Tesla and competitors like Waymo demonstrate superior safety in independent studies, pressure is mounting for harmonized approvals.

Musk’s warning carries the belief that every month of delay may equate to avoidable tragedies on European roads.
