SpaceX Starship prototype in limbo after engine test lights rocket on fire
The fate of SpaceX’s fourth full-scale Starship prototype appears to be in limbo after a third (seemingly successful) engine ignition test unintentionally caught the rocket on fire.
Now more than 12 hours after Starship SN4 fired up its new Raptor engine, the ~30m (~100 ft) tall, 9m (~30 ft) wide prototype is apparently trapped with one or both of its propellant tanks still partially filled with liquid (or gaseous) methane and/or oxygen. An initial road closure scheduled from noon to 6pm local quickly came and went and SpaceX and Cameron County Texas have since modified the paperwork, extending the closure a full 24 hours. In other words, SpaceX has reason to believe that Starship SN4 may continue to be unsafe (i.e. pressurized) as many as ~30 hours after it technically completed its third static fire test – extremely unusual, to say the least.
There’s only one obvious conclusion to draw. Whether it was something invisible to the public eye or damage related to the off-nominal fire that burned for some 15 minutes after Raptor shut down, SpaceX appears – to some extent – to have lost control of Starship SN4.
At the moment, it’s unclear what is wrong and what SpaceX is attempting to do to resolve the problem. Based on photos of Starship SN4 taken before the fire, there is good news and bad news from what can be publicly ascertained. Controlled from the ground by unprotected wires strung up and down the rocket and connected at its base, the uncontrolled fire that burned in at least two locations around Starship’s aft may have severed some or all of those critical connections.
That would render Starship – potentially perfectly healthy and operational – almost entirely uncontrollable, while also potentially removing SpaceX’s access to telemetry. In other words, the company may currently have no idea how pressurized all or part of Starship SN4 is and may also have little to no control of some or all of the rocket. For that to be true, Starship SN4 would, however, have to have less than fully redundant control hardware. To perform hops, for example, the ship would need both wired and radio links capable of sending telemetry and receiving commands to remain both on the ground and after liftoff.
It’s possible that Starship SN4 has the necessary hardware installed but that it wasn’t activated for the static fire test (think “Starship will never leave the ground, why would we need to enable wireless controls?”). It’s also possible that the blown pipe and methane leak that appeared to cause the secondary fire damaged crucial propellant management hardware (valves, pumps, etc.) or was just a symptom of an even worse overpressure event that damaged or destroyed multiple such systems.
Given that safety is almost certainly the priority, chances are that some combination of fairly mild hardware failure and telemetry/control loss has left SpaceX with just enough uncertainty that it can’t risk sending technicians to the launch site to inspect the damage and reestablish control. As a result, the only option left is to quite literally sit and wait until it’s once again safe to approach the rocket. Thankfully, at this point, the risk of the mystery problem actually destroying Starship SN4 is very low. If, as it appears, only its methane tank is affected, leaving some unknown quantity of latent liquid methane trapped inside, it’s possible that waiting will actually solve the problem and safe the rocket.
The fact that Starship hasn’t exploded yet strongly implies either that the amount of propellant trapped is minuscule or that the vast majority of SN4’s propellant management systems (including vents) remain functional. Assuming that’s the case, any remaining cryogenic propellant will eventually boil into gas, increasing the pressure inside Starship’s tanks, while those tanks will continue to vent to prevent an explosion or rupture. Eventually, Starship SN4 will be empty once again and SpaceX will be able to approach the rocket to regain control and begin inspections and repairs.
Regardless, after such an unintentionally eventful static fire test, it’s extremely unlikely that SN4 will be ready for its inaugural flight test within the next few days. Stay tuned for updates as SpaceX works to regain control over the fourth full-scale Starship prototype.

Elon Musk: Self-sustaining city on Mars is plausible in 25-30 years
Musk noted that true self-sufficiency requires Mars to develop “all the ingredients of civilization.”

Elon Musk has stated that a self-sustaining human settlement on Mars could be established in 25-30 years, provided launch capacity increases dramatically in the coming decades.
Speaking at the All-In Summit, the SpaceX CEO said building a self-sufficient colony depends on exponential growth in “tonnage to Mars” with each launch window, highlighting Starship’s role as the company’s pathway to interplanetary initiatives.
Mars settlement goals
Musk noted that true self-sufficiency requires Mars to develop “all the ingredients of civilization,” from food production to microchip manufacturing. Starship Version 3 is expected to support the first uncrewed Mars test flights, while future iterations could reach 466 feet in height and deliver larger payloads critical for settlement. Ultimately, Musk stated that an aggressive timeline for a city on Mars could be as short as 30 years, as noted in a Space.com report.
“I think it can be done in 30 years, provided there’s an exponential increase in the tonnage to Mars with each successive Mars transfer window, which is every two years. Every two years, the planets align and you can transfer to Mars.
“I think in roughly 15, but maybe as few as 10, but 10-15-ish Mars transfer windows. If you’re seeing exponential increases in the tonnage to Mars with each Mars transfer window, then it should be possible to make Mars self-sustaining in about call it roughly 25 years,” Musk said.
Starship’s role
Starship has flown in a fully stacked configuration ten times, most recently in August when it completed its first payload deployment in orbit. The next flight will close out the Version 2 program before transitioning to Starship Version 3, featuring Raptor 3 engines and a redesigned structure capable of lifting over 100 tons to orbit.
While SpaceX has demonstrated Super Heavy booster reuse, Ship reusability remains in development. Musk noted that the heat shield is still the biggest technical hurdle, as no orbital vehicle has yet achieved rapid, full reuse.
“For full reusability of the Ship, there’s still a lot of work that remains on the heat shield. No one’s ever made a fully reusable orbital heat shield. The shuttle heat shield had to go through nine months of repair after every flight,” he said.

Tesla Model Y may gain an extra 90 miles of range with Panasonic’s next-gen battery
The Japanese company is pursuing an anode-free design.

Panasonic is developing a new high-capacity EV battery that could potentially extend the range of a Tesla Model Y by 90 miles.
The Japanese company, one of Tesla’s key battery suppliers, is pursuing an anode-free design that it says could deliver a “world-leading” level of capacity by the end of 2027.
Panasonic’s anode-free design
The technology Panasonic is pursuing would eliminate the anode during the manufacturing process, as noted in a Reuters report. By freeing up space for more active cathode materials such as nickel, cobalt, and aluminum, the Japanese company expects a 25% increase in capacity without expanding battery size.
That could allow Tesla’s Model Y to gain an estimated 145 kilometers (90 miles) of additional range if equipped with a battery that matches its current pack’s size. At the same time, Panasonic could use smaller, lighter batteries to achieve the Model Y’s current range.
Panasonic also aims to reduce reliance on nickel, which remains one of the more costly raw materials. A senior executive previewed the initiative to reporters ahead of a scheduled presentation by Panasonic Energy’s technology chief, Shoichiro Watanabe.
Tesla implications
The breakthrough, if achieved, could strengthen Panasonic’s position as Tesla’s longest-standing battery partner at a time when the automaker is preparing to enter an era of extreme scale driven by high-volume products like the Cybercab and Optimus.
Elon Musk has stated that products like Optimus would be manufactured at very high scale, so it would likely be an all-hands-on-deck situation for the company’s suppliers.
Panasonic did not share details on production costs or how quickly the new batteries might scale for commercial applications. That being said, the Japanese supplier has long been a partner of Tesla, so it makes sense for the company to also push for the next generation of battery innovation while the EV maker pursues even more lofty ambitions.

Tesla called ‘biggest meme stock we’ve ever seen’ by Yale associate dean

Tesla (NASDAQ: TSLA) is being called “the biggest meme stock we’ve ever seen” by Yale School of Management Senior Associate Dean Jeff Sonnenfeld, who made the comments in a recent interview with CNBC.
Sonnenfeld’s comments echo those of many of the company’s skeptics, who argue that its price-to-earnings ratio is far too high when compared to other companies also in the tech industry. Tesla is often compared to companies like Apple, Nvidia, and Microsoft when these types of discussions come up.
Fundamentally, yes, Tesla does trade at a P/E level that is significantly above that of any comparable company.
However, it is worth mentioning that Tesla is not traded like a typical company, either.
Here’s what Sonnenfeld said regarding Tesla:
“This is the biggest meme stock we’ve ever seen. Even at its peak, Amazon was nowhere near this level. The PE on this, well above 200, is just crazy. When you’ve got stocks like Nvidia, the price-earnings ratio is around 25 or 30, and Apple is maybe 35 or 36, Microsoft around the same. I mean, this is way out of line to be at a 220 PE. It’s crazy, and they’ve, I think, put a little too much emphasis on the magic wand of Musk.”
Many analysts have admitted in the past that they believe Tesla is an untraditional stock in the sense that many analysts trade it based on narrative and not fundamentals. Ryan Brinkman of J.P. Morgan once said:
“Tesla shares continue to strike us as having become completely divorced from the fundamentals.”
Dan Nathan, another notorious skeptic of Tesla shares, recently turned bullish on the stock because of “technicals and sentiment.” He said just last week:
“I think from a trading perspective, it looks very interesting.”
Nathan said Tesla shares show signs of strength moving forward, including holding its 200-day moving average and holding against current resistance levels.
Sonnenfeld’s synopsis of Tesla shares points out that there might be “a little too much emphasis on the magic wand of Musk.”
Elon Musk just bought $1 billion in Tesla stock, his biggest purchase ever
This could refer to different things: perhaps his recent $1 billion stock buy, which sent the stock skyrocketing, or the fact that many Tesla investors are fans and owners who do not buy and sell on numbers, but rather on news that Musk might report himself.
Tesla is trading around $423.76 at the time of publication, as of 3:25 p.m. on the East Coast.
