SpaceX Starship booster heads to launch pad for the fifth time

Published

For the fifth time in five months, SpaceX has transported its most advanced Starship booster prototype from the Starbase factory to the launch pad, setting the stage for another round of testing.

Super Heavy Booster 7 (B7) returned to the factory for the fourth time on August 12th after becoming the first prototype of any kind to perform a static fire engine test while installed on SpaceX’s orbital Starship launch mount. In the days prior, the booster completed two back-to-back static fire tests with one of the 20 Raptor engines installed on the rocket, both of which apparently gave SpaceX enough confidence to prepare for the next phase of testing.

That relatively cautious progress only came after SpaceX attempted to test all 33 of the prototype’s Raptors at once during its first engine test. Whether it was the fault of overzealous managers or executives or a genuine oversight is not clear, but the combined behavior of Super Heavy and the orbital launch pad was not properly characterized before testing began. As a result, the cloud of flammable gas the rocket released during its attempted 33-engine ‘spin-prime’ test found an ignition source and violently exploded on July 11th, causing damage throughout Booster 7’s aft engine section that required several weeks of repairs between July 15th and August 6th.

When the Super Heavy rolled to the pad for the fourth time on August 6th, it was missing all 13 center Raptors, leaving only the outer ring of 20 Raptor Boost engines partially installed for the tests that followed. Thankfully, things went much better on the second try and Booster 7 completed two spin-prime tests with a single Raptor engine, followed by two successful static fire tests on August 9th and 11th. The latter test was the longest Starbase static fire ever (by a factor of ~3) and lasted about 20 seconds, allowing SpaceX to test Booster 7’s autogenous pressurization. That system pressurizes Super Heavy’s tanks by turning small quantities of cryogenic liquid propellant into gas, ensuring that its tanks remain stable as they’re rapidly drained of thousands of tons of propellant.

On August 12th, Booster 7 returned to the factory, where workers installed the rocket’s 13 center engines for the second time. Booster 7 headed back to the orbital launch site (OLS) on August 23rd and the pad’s robotic launch tower used a pair of arms to lift the rocket off its transport stand and place it on the launch mount by the end of the day.

In addition to readying Booster 7 for its next phase of static fire testing, teams of SpaceX workers took advantage of the unplanned lull in testing to modify the orbital launch mount. It’s impossible to know what exactly was done without official confirmation, but it’s likely that SpaceX was attempting to quickly fix the shortcoming(s) that allowed the July 11th explosion to happen. Without a fix, it’s unlikely that SpaceX would want to proceed with plans to ignite large numbers of Raptor engines simultaneously – a series of tests that must be completed before Starship can safely attempt its first orbital launch.

It’s unclear what exactly that fix entails, but it could involve a system to constantly flood the engine section with fire-stopping nitrogen gas or potentially take the shape of a system of vents that will connect to every Raptor engine and remove methane gas before it can turn into flammable clouds.

It’s possible that Booster 7 has returned to the launch pad solely for fit checks or some other basic proof-of-concept testing. It’s also possible that the returns signifies that SpaceX is confident in its quick launch mount fix and ready to restart static fire testing.

As Booster 7 prepares for that next phase of testing, SpaceX may also be ready to restart static fire testing with Starship S24, which paused shortly before Super Heavy returned to the factory. SpaceX appears to be modifying the suborbital launch mount and test stand Ship 24 is installed on, which could explain the lack of ship testing since August 11th. SpaceX has 12-hour test windows tentatively scheduled on August 24th and 25th, either of which could be used to test either or both prototypes.

If all goes to plan, Ship 24 and Booster 7 will eventually complete all the qualification testing SpaceX can throw at them and be ready to support Starship’s first orbital launch attempt sometime before the end of 2022.

Google parent company Waymo has announced plans to bring its self-driving robotaxis to yet another U.S. city, adding to the list of those it plans to deploy the service to in the next several months.

On Tuesday, Waymo announced in a press release that it will be bringing its autonomous ride-hailing vehicles to Washington D.C. in 2026, after it recently announced plans to start deploying the services in Atlanta, Georgia, and Miami, Florida, sometime in 2025. The D.C. services will utilize the Waymo One app, unlike some of the cities which will roll out through a partnership agreement.

“Waymo One is making fully autonomous driving a reality for millions of people across the U.S.” said Tekedra Mawakana, Waymo Co-CEO. “We’re excited to bring the comfort, consistency, and safety of Waymo One to Washingtonians, those who work and play in the city every day, and the millions of people from around the world who travel to the District every year.”

The company says it plans to continue working closely with legislators on regulations needed to operate driverless vehicles in D.C. Additionally, Waymo says it’s currently operating over 200,000 fully autonomous, paid driverless ride-hails per week, as Tesla and others aim to enter the commercial robotaxi space in the coming months.

“I’ve experienced firsthand how safely the Waymo Driver operates around pedestrians, cyclists, and other vulnerable road users,” writes Jonathan Adkins, the CEO of the Governors Highway Safety Association. “Waymo has worked with GHSA and our first responder network as they’ve expanded their service, always putting safety first. As someone who walks to work almost every day, I’m excited to share the road with Waymo in Washington, D.C.”

Waymo also recently launched its robotaxi services will deploy in a partnership with Uber in Austin, Texas, where Tesla also has a so-called Gigafactory and plans to roll out its own robotaxi services later this year. The company currently operates paid driverless ride-hailing or early testing in the following cities, primarily in the U.S.:

The news also comes as Tesla aims to roll out its first unsupervised drives with its in-house Full Self-Driving (FSD) software this summer, along with rolling out initial robotaxi ride-hailing services. While the company doesn’t currently operate any paid ride-hailing like Waymo One, the company’s vehicles can generate real-time training data from drivers with FSD Supervised engaged.

Tesla’s Superchargers are now officially open to Hyundai’s electric vehicles (EVs) across the U.S., adding to the wave of auto brands that can now charge on the once-exclusive network.

In a press release on Tuesday, Hyundai announced that owners of the Kona electric, Ioniq hatchback, Ioniq 5, Ioniq 5 N, and Ioniq 6, can charge at Tesla Superchargers in the U.S. using a CCS to NACS adapter, which the company is offering complimentary to owners. The news is set to give access to roughly 20,000 Superchargers in the U.S., as Tesla continues to roll out access to non-Tesla EV brands across the industry.

Hyundai says that those who purchased their EVs prior to January 31, 2025 will begin receiving emails on how to claim the free NACS adapters starting the week of April 7. The news also comes after Hyundai was the first automaker to debut a native NACS port with the Ioniq 5, beginning late last year.

“Starting today, more Hyundai EV customers will have access to 20,000 Tesla Superchargers across North America, doubling their fast-charging options,” says Olabisi Boyle, Hyundai North America’s SVP of product planning and mobility strategy. “This move improves the public charging experience by giving our customers even more choice. It’s a vital part of our commitment to ease America’s transition to electric vehicle ownership.”

Currently, the news only applies to Superchargers in the U.S., though one spokesperson from the automaker told Teslarati that more details are expected to come about the launch of access in Canada later this year.

Tesla now lists Hyundai, and its subsidiary Genesis, on its website as EV brands that are able to charge at its Superchargers, along with several others which have been added in the past several months such as Polestar, Volvo, Mercedes-Benz, Lucid, and Rivian, among others.

Hyundai also had record auto sales in the U.S. in 2024, with general retail sales up 4 percent and EV sales up 13 percent year over year.

Tesla CEO Elon Musk’s simple message to vandals

Tesla CEO Elon Musk had a simple and straightforward message to the vandals who continue to damage cars, showrooms, and Superchargers that the company and its owners utilize during an All-Hands meeting last week.

For the first time, Tesla and Musk broadcasted on X an All-Hands meeting the company held with its employees.

It seemed to be a justified response to skeptics and investors who have said that Musk has spent more time worrying about the Department of Government Efficiency (DOGE) than Tesla.

During the meeting, Musk showed the company’s roadmap for the remainder of 2025 and into 2026 and aimed to resolve any sort of skepticism regarding his commitment. He told the employees to “hang onto their stock,” and commented on Tesla’s future impact:

“It’s very difficult like for people in the stock market, especially those that look in the rearview mirror — which is most people — to imagine a future where suddenly a 10 million vehicle fleet has five to ten times the usefulness. It’s so profound and there’s no comparison with anything in the past that it does not compute. But it will compute in the future.”

However, Musk did not stop there. He also had a message for those who have gone out of their way to key, damage, and sometimes even destroy Tesla vehicles and showrooms.

Several locations have been hit with gunfire, Molotov cocktails, and other things, while owners are reporting petty vandalism like keying and slashing tires more frequently now than ever.

Musk’s message to the vandals was simple:

“This is psycho. Stop being psycho!”

He continued:

“If you read the news, it feels like, you know, Armageddon. It’s like, I can’t walk past the TV without seeing a Tesla on fire. Like, what’s going on? Some people, it’s like, listen, I understand if you don’t wanna buy our product, but you don’t have to burn it down. That’s a bit unreasonable.”

Tesla’s biggest haters have continued to spew violence toward the company and owners of its cars, with some even putting on bumper stickers that read things like “I bought this before Elon went crazy!” to hopefully divert attackers.

The company also has the help of the federal government. The FBI has already established a task force to help investigate instances of vandalism and violence against Tesla. Additionally, President Trump has said attacks against the company are being considered as domestic terrorism.
