SpaceX has rolled Falcon 9 and Crew Dragon out to Pad 39A for the second time ever in preparation for a full wet dress rehearsal (WDR) and static fire – no earlier than Jan. 23 – of booster B1051’s nine Merlin 1D engines, preparing for an orbital launch attempt that slipped from NET Feb. 9 to Feb. 16 earlier this week.

While this milestone is important for myriad other reasons, it happens to be exceptionally unique thanks to one particularly surprising feature: Falcon 9 rolled out for its static fire with Crew Dragon (the rocket’s payload) still attached. This will be the first time in more than 28 months – since Amos-6, the last catastrophic Falcon 9 failure – that SpaceX has performed its routine on-pad static fire with a valuable payload attached to the rocket.

On September 1st, 2016, a SpaceX Falcon 9 experienced the rocket family’s second catastrophic failure ever when supercool liquid oxygen froze around a COPV’s carbon fiber wrappings, expanding just enough to breach the ultra-high-pressure vessel. Falcon 9 and its ~$200M Amos-6 satellite payload were completely destroyed, while Launch Complex 40 (LC-40) suffered tens of millions of dollars of damage that would effectively require it to be completely rebuilt over the course of more than a year.

After Amos-6, SpaceX immediately halted the practice of including customer payloads on Falcon 9 during static fires, used to save 24-48 hours of time between static fire and launch. SpaceX nevertheless retained the option if customers were to explicitly request it, otherwise wisely concluding (likely with more than a little encouragement from insurance companies) that expediting schedules by a few dozen hours was not worth the entirely unnecessary risk to satellite payloads that often cost hundreds of millions of dollars and take years to build.

Given that SpaceX has stuck to that practice for all 38 Falcon 9 launches it has performed between Amos-6 and the present day, it seems all but guaranteed that the first orbit-ready Crew Dragon’s presence on Falcon 9 during its static fire has been done only at the specific request of the launch customer – in this case, NASA. It’s probably not hyperbolic to argue that Demo-1’s (DM-1) Crew Dragon is the most valuable, important, expensive, and irreplaceable spacecraft SpaceX has ever attempted to launch, having likely spent millions of work hours building, changing, refining, and testing it to meet NASA’s exacting and sometimes absurd requirements.

If Falcon 9 B1051 were to fail with Crew Dragon atop it during its Pad 39A static fire, it might be possible for the DM-2’s Crew Dragon to be completed and modified for an uncrewed test flight with just six months of delay, assuming Falcon 9’s mode of failure could be investigated and repaired to NASA’s satisfaction. However, the destruction of the DM-1 capsule and trunk could almost indefinitely delay SpaceX’s first crewed launch, dependent upon an inflight-abort test that is supposed to use the refurbished DM-1 capsule, while the Crew Dragon currently supposed to launch after DM-2 is unlikely to be ready before August or September 2019.

 

Ultimately, NASA likely requested that Crew Dragon remain atop Falcon 9 for this static fire out of some desire for a full-fidelity test environment and complement of data. There is perhaps a very limited chance that Crew Dragon will be fully fueled with hydrazine (MMH/NTO) and have its launch escape system (LES) active and ready to go in the event of a rocket failure.

Why they deemed the immense potential risk to be worthwhile is far less clear. Whether it is being done out of complacency or a desire for expediency or ultra-realistic test data, the risk is the same. In theory, Falcon 9 has been tested extensively and should operate perfectly, just as expected. So was Amos-6’s Falcon 9.

SpaceX is gearing up for the 13th Starship integrated flight test, which is currently scheduled for Thursday, July 16, with the launch window opening up at 6:30 PM E.T. from Starbase in South Texas.

This mission, the second with the V3 Starship and Super Heavy vehicles, builds directly on the foundation of Flight 12 while introducing ambitious new objectives, including the debut deployment of next-generation Starlink V3 satellites.

The rapid iteration between flights underscores SpaceX’s “fail fast, learn faster” philosophy, with engineers addressing specific anomalies from the previous test to push reusability and payload capabilities further.

Flight 12 occurred earlier in 2026 and encountered notable challenges that became catalysts for Flight 13’s improvements. Issues included booster course deviations during the flip maneuver after stage separation, reusability problems with Super Heavy’s Raptor engine relights for the boostback burn, and an engine-out event on the Starship upper stage during its propulsion phase.

These hiccups, while they did not prevent overall mission success, highlighted areas needing refinement for more consistent performance and higher safety margins in future operational flights.

In response, SpaceX implemented a comprehensive suite of both hardware and software upgrades.

For the booster, engineers developed a more robust stage separation flip sequence to maintain stable orientation and prevent off-course rotation. Hardware modifications have enhanced Raptor re-light reliability during the boostback burn, complemented by updated engine alarms and abort logic tailored for multi-engine operations. On the Starship side, propulsion system changes directly tackle the Flight 12 engine-out scenario, improving redundancy and operational resilience.

Another major focus of SpaceX for Flight 13 was the advancements in the heat shield. New tile designs and attachment mechanisms, including tests of aft flaps and skirts, aim to boost durability.

Load-sensing tiles will measure real-time stresses during atmospheric entry, while white-painted tiles simulate missing ones as imaging targets. Six of the 20 Starlink V3 satellites carried aboard will feature specialized cameras to scan and transmit heat shield imagery back to ground teams, providing critical data for future return-to-launch-site attempts.

The mission profile also includes a higher dynamic pressure ascent to stress-test the thermal protection system and increase payload potential, alongside a planned in-space Raptor engine relight demonstration.

The V3 Starlink satellites themselves mark a leap forward, equipped with laser links, deployable solar arrays, and improved antennas to expand network capacity and speeds.

The company wrote:

“For the first time, Starship will carry V3 Starlink satellites to space, which aim to greatly expand the network’s capacity and user speeds. As part of this initial test, Starship is planned to deploy 20 satellites which will extend solar arrays and antennas and will attempt to connect with ground stations in South Africa and the larger Starlink constellation via high-capacity lasers. Six of the satellites have been modified with a suite of cameras to scan Starship’s heat shield and transmit imagery down to operators to continue testing methods of analyzing Starship’s heat shield readiness for return to launch site on future missions. Several tiles on Starship have been painted white to simulate missing tiles and serve as imaging targets in the test.”

This dual-purpose flight tests both vehicle reliability and satellite tech in one integrated operation.

These iterative changes, catalyzed by Flight 12’s data, position Starship closer to rapid reusability goals essential for ambitious programs like Artemis lunar missions and global Starlink coverage.

As SpaceX continues its aggressive test cadence, Flight 13 exemplifies how targeted engineering responses to real-flight anomalies accelerate progress toward fully operational, high-cadence launches. Success here could mark another milestone in the Starship program for SpaceX.

SpaceX is preparing for the 13th integrated flight test of its Starship system, with a targeted launch as early as Thursday, July 16. The 90-minute launch window opens at 5:45 p.m. CT from Starbase in South Texas.

This comes roughly seven weeks after Flight 12 on May 22, underscoring the company’s accelerating pace in its rapid development campaign. The mission will use the latest Starship and Super Heavy V3 vehicles equipped with Raptor 3 engines. Booster 20 will attempt a controlled boostback burn, followed by a splashdown in the Gulf of Mexico, while Ship 40 will follow a suborbital trajectory.

Key objectives for Flight 13 will include demonstrating reliable stage separation, engine performance under various conditions, and controlled reentry.

A major milestone for Flight 13 is the first deployment of 20 next-generation Starlink V3 satellites. These satellites feature advanced laser links for inter-satellite communication, deployable solar arrays, and onboard cameras, six of which will capture imagery of Starship’s heat shield during flight.

Several heat shield tiles on Ship 40 will be painted white to serve as imaging targets, while additional experiments test upgraded tiles on aft flaps, modified attachments on the aft skirt, and load-sensing tiles to measure stresses. The upper stage will also attempt a single Raptor engine relight in space before a targeted splashdown in the Indian Ocean.

These tests build directly on lessons from Flight 12, which introduced the V3 configuration but encountered issues including a booster flip anomaly during boostback and an engine-out event on the ship. Hardware and software modifications on Booster 20 and Ship 40 aim to improve engine relight reliability, startup sequencing, and overall robustness.

The short interval between Flights 12 and 13 highlights SpaceX’s iterative approach. Elon Musk has repeatedly emphasized that Starship launches will become “incredibly common” in the coming years.

The company envisions scaling to rates as high as one launch per hour within 4-5 years, potentially enabling thousands of flights annually. Such cadence is essential for Starship’s goals: establishing orbital refueling for lunar and Mars missions, deploying massive satellite constellations, and making life multiplanetary.

Elon Musk posted a candid admission on his social media platform X on June 9, declaring that he had been “clearly wrong” about Anthropic. The statement marked a notable reversal from his earlier skepticism toward the AI company.

In September, Musk had written, “Winning was never in the set of possible outcomes for Anthropic,” reflecting his view at the time that the startup had lacked the foundation or even the trajectory to succeed in what is an incredibly intense race for advanced artificial intelligence.

Musk’s latest post came amid discussion of Anthropic’s reliance on external compute resources. He praised the company’s progress, stating that Anthropic is “obviously currently the leader in AI” and that “no company has released a model as good as Mythos/Fable,” with expectations of a strong follow-up in Mythos 2.

The tone shifted dramatically from dismissal to acknowledgement of superior performance.

The context of Musk’s comments added significance. Anthropic has been operating under a recent compute deal with SpaceXAI, Musk’s AI infrastructure-focused venture. The pair entered a short-term GPU lease agreement initiated in May, providing Anthropic access to critical computing power for training and deploying its frontier models.

Some observers had speculated that Musk could leverage this dependency to disadvantage a rival. Musk directly addressed the possibility, writing, “I would never cut them off in a way that hurt them badly, even as a competitor. That’s not my style.”

To support his commitment to ethical competition, Musk referenced concrete examples from his other companies. Tesla famously open-sourced its entire portfolio of electric vehicle patents in 2014. The move was designed to accelerate the global adoption of sustainable transportation technology rather than protect proprietary advantages.

Tesla also made its Supercharger network available to competing electric vehicle manufacturers, transforming what could have remained an exclusive charging ecosystem into a shared infrastructure that benefits the broader industry and reduces barriers for EV adoption.

Musk further pointed to SpaceX’s practices, noting that the company launches satellites for competing commercial systems “with no increase in price or use of unfair terms.” He extended the principle to his social platform, observing that “even my worst enemies attack me on this platform,” underscoring preference for open discourse over retaliation.

These examples have illustrated Musk’s long-standing philosophy that long-term technological progress is best served by open competition and infrastructure sharing rather than leveraging market power to stifle rivals. In the fast-evolving AI sector, where compute resources and model capabilities determine leadership, Musk’s stance suggests a willingness to compete on innovation and performance alone.

Musk’s admission arrives as SpaceXAI itself advances its own frontier models while maintaining business relationships across the ecosystem. By publicly correcting his earlier assessment and reaffirming principles of fair play, Musk highlights a model of competition that prioritizes advancement of the field over short-term tactical advantages.
