SpaceX’s newest Starship spacecraft prototype unintentionally lifted off during a critical test at the company’s Boca Chica, Texas facilities – a development that was almost certainly unplanned.

On February 26th, under the cover of an incredibly thick fog bank, SpaceX carefully transported its second full-scale Starship prototype – measuring some 30m (100 ft) tall and 9m (30 ft) wide – to its Boca Chica, Texas launch and test pad, situated just a mile or so down the road from an ever-growing rocket factory. After just two days of last-second work spent outfitting the giant rocket tank with a few additional sensors and fully connecting it to ground systems (electricity, communications, and fluids), SpaceX kicked off the second cryogenic ‘proof’ test of an integrated Starship tank section.

An opaque layer of frost quickly developed on the ship’s mirror-smooth hull, effectively serving as a giant gauge for the liquid nitrogen pooling inside it. About an hour after faux-propellant (liquid nitrogen) loading began, Starship SN01’s liquid oxygen tank violently burst, causing the entirety of the vehicle’s 30-40 metric ton (65,000-90,000 lb) bulk to launch several dozen feet into the air. Stacked atop the oxygen tank, SN01’s methane tank – likely pressurized with nitrogen or oxygen gas – shot off like a house-sized bullet when the rest of the tank section impacted the ground, flying some 150-300+ meters (500-1000 ft) from the pad.

Long-time Boca Chica resident, photographer, and videographer Mary (also known as “bocachicagal” on forums) captured the seemingly unintentional Starship failure in spectacular detail on February 28th. Given how high the heavy vehicle jumped after its aft tank dome failed, as well as how fast the house-sized methane tank flew after it breached, it’s safe to say that both were significantly pressurized before the anomaly.

What’s unclear is what exactly went wrong with Starship SN01 and whether SpaceX expected it to fail during the test. Known as a cryogenic proof test, SpaceX pressurized the ship’s tanks with liquid nitrogen and a gas of some kind in an effort to verify its structural integrity and determine if it was safe to proceed to more risky tests. According to CEO Elon Musk, Starship SN01 was actually meant to support a full wet dress rehearsal (WDR) with liquid oxygen and methane, followed by a Raptor engine static fire test shortly thereafter.

That plan is clearly moot, now, and also seems to indicate that SpaceX is likely somewhat surprised about the outcome of SN01’s first proof test. Thankfully, this particular Starship was built quickly (and thus likely cheaply), coming together in an unfathomable four weeks. Additionally, SpaceX’s second serial Starship prototype (SN02) is already well on its way to the launch pad, with multiple sections of stacked steel rings in work. Based on the four or so weeks SN01 took to go from first weld to pressure test, SN02 could be just two or three weeks away from its own proof test debut.

Tesla Supercharger Diner food menu gets a sneak peek as construction closes out

What are you ordering at the Tesla Diner?

The Tesla Supercharger Diner in Los Angeles is nearing completion as construction appears to be winding down significantly. However, the more minor details, such as what the company will serve at its 50s-style diner for food, are starting to be revealed.

Tesla’s Supercharger Diner is set to open soon, seven years after CEO Elon Musk first drafted the idea in a post on X in 2018. Musk has largely come through on most of what he envisioned for the project: the diner, the massive movie screens, and the intended vibe are all present, thanks to the aerial and ground footage shared on social media.

We already know the Diner will be open 24/7, based on decals placed on the front door of the restaurant that were shared earlier this week. We assume that Tesla Optimus will come into play for these long and uninterrupted hours.

The Tesla Diner is basically finished—here’s what it looks like

As far as the food, Tesla does have an email also printed on the front door of the Diner, but we did not receive any response back (yet) about what cuisine it will be offering. We figured it would be nothing fancy and it would be typical diner staples: burgers, fries, wings, milkshakes, etc.

According to pictures taken by @Tesla_lighting_, which were shared by Not a Tesla App, the food will be just that: quick and affordable meals that diners do well. It’s nothing crazy, just typical staples you’d find at any diner, just with a Tesla twist:

As the food menu is finalized, we will be sure to share any details Tesla provides, including a full list of what will be served and its prices.

Additionally, the entire property appears to be nearing its final construction stages, and it seems it may even be nearing completion. The movie screens are already up and showing videos of things like SpaceX launches.

There are many cars already using the Superchargers at the restaurant, and employees inside the facility look to be putting the finishing touches on the interior.

It’s almost reminiscent of a Tesla version of a Buc-ee’s, a southern staple convenience store that offers much more than a traditional gas station. Of course, Tesla’s version is futuristic and more catered to the company’s image, but the idea is the same.

It’s a one-stop shop for anything you’d need to recharge as a Tesla owner. Los Angeles building permits have not yet revealed the date for the restaurant’s initial operation, but Tesla may have its eye on a target date that will likely be announced during next week’s Earnings Call.

Tesla’s longer Model Y did not scale back requests for this vehicle type from fans

Tesla fans are happy with the new Model Y, but they’re still vocal about the need for something else.

Tesla launched a slightly longer version of the Model Y all-electric crossover in China, and with it being extremely likely that the vehicle will make its way to other markets, including the United States, fans are still looking for something more.

The new Model Y L in China boasts a slightly larger wheelbase than its original version, giving slightly more interior room with a sixth seat, thanks to a third row.

Tesla exec hints at useful and potentially killer Model Y L feature

Tesla has said throughout the past year that it would focus on developing its affordable, compact models, which were set to begin production in the first half of the year. The company has not indicated whether it met that timeline or not, but many are hoping to see unveilings of those designs potentially during the Q3 earnings call.

However, the modifications to the Model Y, which have not yet been officially announced for any markets outside of China, still don’t seem to be what owners and fans are looking forward to. Instead, they are hoping for something larger.

A few months ago, I reported on the overall consensus within the Tesla community that the company needs a full-size SUV, minivan, or even a cargo van that would be ideal for camping or business use.

Tesla is missing one type of vehicle in its lineup and fans want it fast

That mentality still seems very present amongst fans and owners, who state that a full-size SUV with enough seating for a larger family, more capability in terms of cargo space for camping or business operation, and something to compete with gas cars like the Chevrolet Tahoe, Ford Expedition, or electric ones like the Volkswagen ID.BUZZ.

We asked the question on X, and Tesla fans were nearly unanimously in support of a larger SUV or minivan-type vehicle for the company’s lineup:

Here’s what some of the respondents said:

Tesla is certainly aware that many of its owners would like the company to develop something larger that competes with the large SUVs on the market.

However, it has not stated that anything like that is in the current plans for future vehicles, as it has made a concerted effort to develop Robotaxi alongside the affordable, compact models that it claims are in development.

It has already unveiled the Robovan, a people-mover that can seat up to 20 passengers in a lounge-like interior.

The Robovan will be completely driverless, so it’s unlikely we will see it before the release of a fully autonomous Full Self-Driving suite from Tesla.

Tesla has launched its first-ever Virtual Power Plant program in the United Kingdom. This feature enables users of solar panels and energy storage systems to sell their excess energy back to the grid.

Tesla is utilizing Octopus Energy, a British renewable energy company that operates in multiple markets, including the UK, France, Germany, Italy, Spain, Australia, Japan, New Zealand, and the United States, as the provider for the VPP launch in the region.

The company states that those who enroll in the program can earn up to £300 per month.

Tesla has operated several VPP programs worldwide, most notably in California, Texas, Connecticut, and the U.S. territory of Puerto Rico. This is not the first time Tesla has operated a VPP outside the United States, as there are programs in Australia, Japan, and New Zealand.

This is its first in the UK:

Tesla is not the only company that is working with Octopus Energy in the UK for the VPP, as it joins SolarEdge, GivEnergy, and Enphase as other companies that utilize the Octopus platform for their project operations.

It has been six years since Tesla launched its first VPP, as it started its first in Australia back in 2019. In 2024, Tesla paid out over $10 million to those participating in the program.

Tesla VPP program in California hits new capacity milestone

Participating in the VPP program that Tesla offers not only provides enrolled individuals with the opportunity to earn money, but it also contributes to grid stabilization by supporting local energy grids.
