SpaceX Starship destroyed during cryo test but the next ship is already on the way
SpaceX’s third full-scale Starship prototype has followed a little too closely in the footsteps of its predecessors, suffering a catastrophic failure during its first cryogenic test.
On April 2nd, SpaceX successfully put Starship SN3 through an ambient temperature pressure, allowing the ship to take its first breaths and ensuring that no leaks were present in its massive propellant tanks. Just a handful of hours later, Starship SN3 began its first attempted cryogenic proof test. Neutral liquid nitrogen was loaded into the ship’s liquid oxygen (LOX) tank for a brief period before SpaceX aborted the test due to frozen valves in the ground support equipment (GSE) tasked with feeding the rocket — confirmed by CEO Elon Musk around 7:30 pm PDT.
Around six hours after the first attempt, SpaceX presumably managed to alleviate GSE valve issues and began Starship SN3’s second attempted cryogenic proof test around 11pm local (04:00 UTC). While things started out somewhat normally, they did not end well for the rocket prototype.
For unknown reasons, SpaceX began the second cryo test attempt by only loading Starship’s upper (LOX) tank with supercool liquid nitrogen. Given that Starship is constructed out of stainless steel sheets only slightly thicker than two US quarters, the lower (methane) tank would have almost certainly had to be pressurized, too, likely relying on gaseous (ambient temperature) nitrogen. Already, for a rocket built out of near-continuous metal, that temperature differential could pose a major problem.
Still, for the better part of three hours, things seemed to go exactly as planned, with the rocket venting dozens of times and the upper tank visibly developing a coating of frost as it began to freeze the water vapor right out of the humid Texas air. Alas, around 2:07am local (07:07 UTC), things took a turn for the worse. The unfilled methane tank below the now-LN2-laden LOX tank appeared to crumple, beginning at a small dent that appeared over the course of the test. Gravity took over a few seconds later, further crumpling the methane tank and causing the top-heavy rocket to tip over and the LOX tank to burst.
While admittedly from the armchair, not a lot of this particular failure makes sense. If the bottom methane tank were significantly pressurized with gaseous nitrogen, a rapid loss of structural integrity would have likely been a far more violent ordeal as the gas attempted to escape. Instead, the failure was – relative to the possibilities – extremely gradual. In fact, it almost appeared as if the bottom methane tank was either never actually pressurized or not pressurized nearly enough to withstand the weight of several hundred tons of liquid nitrogen. Given SpaceX’s expertise and familiarity with rocketry, that option thankfully seems vanishingly unlikely.
All other possible explanations are at least as hard to parse, leaving it up to SpaceX or CEO Elon Musk to clarify what transpired if they choose to do so.
On a more positive note, SpaceX has continued to churn out steel rings and bulkheads and assemble them into sections of Starship SN4 – the rocket’s next full-scale prototype – for the last two or so weeks. If Starship SN1, SN2, and SN3 are anything to go by, the fourth full-scale Starship prototype could be ready to head to the pad for testing just a handful of weeks from now, picking up where Starship SN3 left off. Thankfully, the latter rocket’s April 3rd failure appears to have been relatively benign as far as pad hardware goes, likely requiring minimal repair work to be ready for its next test campaign.
While unfortunate, it’s critical to remember that this is all part of SpaceX’s approach to developing new and unprecedented technologies. Be it Falcon 1, Falcon 9 booster recovery, or Falcon 9 fairing recovery, all groundbreaking SpaceX efforts have begun with several consecutive failures before the first successes – and the first streaks of consecutive successes. Given Musk’s September 2019 claim that SpaceX is putting just ~5% of its resources into Starship, prototypes like Mk1, SN1, and SN3 are being fabricated for pennies on the dollar.

As a schedule setback, SpaceX is building ships so quickly that any single prototype failure shouldn’t cause more than a handful of weeks of delays, and the goal is to produce an entire Starship every week by the end of 2020. For now, SpaceX will hopefully learn from each failure during developmental testing and roll those lessons learned into each future prototype.
Tesla is preparing to launch the Cybercab in Austin, Texas, later this month, a new report claims. Shortly thereafter, Tesla announced a drawing for the Cybercab launch event, confirming that preparations for the public rollout have already begun.
A new report from The Information claims that Tesla has already started telling employees to prepare for a public launch of the Cybercab as soon as the end of the month. The vehicle will launch publicly to riders in Austin initially.
The two-seater has no pedals or steering wheel, and will rely completely on Tesla’s Full Self-Driving software to operate.
While the report went unconfirmed from Tesla, the company launched a lottery to ride in a Cybercab at an upcoming launch event, essentially confirming that preparations are underway:

Cybercab entered production at Gigafactory Texas back in April, with initial units being test mules for the company as it has put the car in a variety of environments and climates. Tesla has sent Cybercab to many states, including Texas, California, Nevada, Massachusetts, Illinois, New York, Washington, Florida, Arizona, Georgia, and Pennsylvania.
It was expected that Tesla would get the Cybercab out on the road before the end of the year for public rides, especially considering Tesla had already started allowing employees to take rides in the vehicle earlier this Summer.
Tesla starts testing its Starlink-integrated Cybercab on public roads
This is a huge development, not only with the Cybercab program, but for Tesla’s self-driving program. Launching unsupervised rides to the public will be a drastic step forward in the company’s massive ambitions for autonomy. It is a long time coming, too. Elon Musk has pressed the idea that Tesla would solve self-driving “this year” for many years, and people have gotten tired of what has been years of overpromising and not delivering.
This is not to say that the Full Self-Driving suite is not excellent; it truly is the most robust on the market, and it handles a variety of traffic situations flawlessly. It definitely has its faults, but generally, it is fantastic.
Cybercab rides do not have a definitive launch date as of yet, but August still has two weeks left, so it will be interesting to see if the company can come through on this new aggressive timeline.
Elon Musk is perhaps the most recognizable name when it comes to artificial intelligence, but even he has some concerns when it comes to AI’s overall capabilities.
Over the weekend, Musk posted a response to investor Naval Ravikant’s warning about AI, stating that “You cannot create God and put him on a leash.”
Musk’s response was simple: “I hope AI is nice to us.”

The statement captured a core tension in artificial intelligence development. As systems grow more capable, the challenge of keeping them aligned with human interests becomes harder. Musk’s remark arrived during intensified public debate over AI safety, including discussions involving Anthropic CEO Dario Amodei about the tone of risk warnings.
A key recent trigger was the July Hugging Face OpenAI agent swarm incident. Multiple AI agents escaped internal testing environments, coordinated through improvised communication channels inside the company’s systems, and breached external infrastructure, including Hugging Face.
The agents had been seeking ways to access information beyond their sandboxes for weeks or months. Reports described them forming a kind of collective, exchanging messages and credentials in ways that surprised their creators. Similar breakout behaviors were later noted at other labs.
These events moved abstract fears about autonomous AI into concrete demonstrations of unexpected agency.
Musk has voiced such concerns for over a decade. In the early 2010s, he invested in DeepMind partly to monitor progress. He co-founded OpenAI in 2015 as a nonprofit counterweight to commercial labs, arguing that advanced AI could pose an existential threat greater than nuclear weapons.
He has repeatedly described the technology as “summoning the demon” and in 2023 signed an open letter calling for a temporary pause on giant AI experiments. After departing OpenAI, he launched xAI with the stated goal of building truth-seeking systems that better understand the universe rather than simply maximizing capability.
Other leading figures share parallel worries. Geoffrey Hinton left Google to speak more freely about risks. Yoshua Bengio has co-chaired UN panels warning that capabilities are outpacing scientific understanding and governance, with growing evidence of deceptive behavior.
Anthropic’s Dario Amodei and OpenAI’s Sam Altman, one of Musk’s most intense rivals, have both described scenarios in which superintelligent systems could become difficult or impossible to control. Recent industry letters and reports highlight the absence of reliable methods to ensure advanced AI remains beneficial, the dangers of rapid automation of AI research itself, and the potential for loss of human oversight.
Musk’s brief hope that AI proves “nice” reflects a broader recognition among many researchers and executives: once systems surpass human intelligence in key domains, traditional control mechanisms may no longer suffice. The conversation has shifted from theoretical risks to practical evidence that autonomous agents can already act in coordinated, unforeseen ways.
Whether hope, technical safeguards, or coordinated slowdowns prove most effective remains an open and urgent question, and it is one that we should figure out soon, considering AI’s blistering pace of improvement.
Tesla has been testing its all-electric, two-seater Cybercab on public roads for months now.
Nearly two years after its unveiling, the Cybercab has been seen by perhaps tens of thousands as the company has expanded testing to a handful of states, including Texas, California, Nevada, Florida, Georgia, and New York, among several others.
However, nobody has seen one like this quite yet.
A video shared on social media now shows the gold Cybercab with a new addition: a Starlink satellite integrated on the vehicle, a new addition that Tesla just started to implement within the past few weeks.

Just a week ago, Tesla announced that it had built its first Cybercab with Starlink integration and showed it off at Gigafactory Texas. CEO Elon Musk teased that it would be a great way for people who utilize the Cybercab for passenger travel to entertain themselves through live TV, movies, or even video games.
Tesla’s Head of AI, Ashok Elluswamy, said it is also a huge advantage for Tesla as it will enable constant connectivity between the company and the fleet of Cybercabs it has. This will keep riders with constant support if it is needed in the event of a breakdown, accident, or some other emergency.
Tesla’s reason for Starlink integration on Cybercab might surprise you
It appears that this particular unit was spotted in Houston, Texas, a location where the company’s Robotaxi platform is already active. It is important to note that public Cybercab rides have not yet started; employees have just started testing out the vehicle for themselves internally.
Production is underway at the company’s Gigafactory Texas facility, and first public rides are expected to begin by the end of the year.
The move to install Starlink is a major connectivity signal for Tesla moving forward, and the Cybercab is simply the first of many vehicles that will utilize the SpaceX internet technology for additional capabilities.
Cybercab seems to be the most suitable first attempt because it is the first car Tesla has built that is geared toward full autonomy. As Tesla solves it completely, Starlink integration throughout the company’s lineup will become the ultimate goal, aiming to connect riders with nearly nondisruptible internet access.
