SpaceX’s fifth full-scale Starship prototype is fast approaching its first Raptor static fire tests after the company recently delivered one of the newest engines to the launch site.

Known as Starship SN5, the ship is the fifth SpaceX has built since full-scale prototype development began in early 2019, as well as the fourth full-scale ship the company has completed since it began producing upgraded hardware in January 2020. SN5 rolled from SpaceX’s Boca Chica, Texas rocket factory to nearby test and launch facilities on June 24th, less than a month after Starship SN4 was destroyed by operator error minutes after completing its fourth Raptor static fire in four weeks.

While Starship SN5 was already more or less complete, SN4’s explosive demise damaged the launch mount (used to secure and fuel prototypes) beyond repair, forcing SpaceX to rapidly build and outfit a replacement. SpaceX finished that replacement mount around June 20th, installed SN5 on it a few days later, and then spent about a week finalizing and inspecting both components.

After barely a month of downtime, Starship SN5 kicked off its first gauntlet of tests late on June 30th, carrying on into the early morning of July 1st. As usual, SpaceX began with an ambient-temperature pressure test, filling Starship’s tanks with neutral nitrogen gas to check for leaks. This time around, SN5 must have been put together with exceptional care, as the company was able to immediately proceed into the ship’s first cryogenic proof test just a few hours later.

CEO Elon Musk has yet to offer any confirmation but the implication is that SN5 performed beautifully during its first liquid nitrogen proof test. Notably, based on NASASpaceflight.com’s excellent unofficial coverage, SN5’s cryo proof was uniquely ambitious. It’s unclear what if the test infrastructure, SN5, general confidence in the vehicle, or some combination of the above components were upgraded, but SpaceX appeared to load Starship SN5 with liquid nitrogen incredibly quickly, taking just 20-30 minutes to fully fuel the rocket. Given that all of that liquid nitrogen (some 1000+ metric tons or ~3.2 million gallons) is being loaded through a single “quick disconnect” panel, it’s no mean feat and far outweighs SpaceX’s already speedy Falcon 9 and Heavy propellant loading.

SpaceX is famously the only current launch vehicle operator known to “sub-cool” its rockets’ propellant, effectively squeezing a performance boost of 5-10% out of the same rocket hardware by making said propellant colder – and thus denser. That performance increase comes with tradeoffs, though, adding significantly tighter operational constraints, lowering delay tolerances, and necessitating an extremely quick propellant load. Sub-cooled liquid oxygen and methane has always been part of SpaceX’s plans for Starship, so fast-load tests were inevitable, but it’s a great sign that the company is starting to seriously think about capabilities that will be necessary for efficient orbital launches.

Meanwhile, labeled “27”, the engine – logically assumed to be Raptor SN27 – SpaceX has just installed on Starship SN5 is also of interest. On top of Musk’s recent confirmation that SpaceX is already building Raptor SN30 (probably SN31 or SN32, now), SN27’s assignment to Starship SN5 confirms that the company has managed to complete (and test) at least one next-generation engines every other week since the first full-scale engine shipped to McGregor, Texas in February 2019.

For a brand new engine as complex as Raptor, that’s an impressive production milestone. Per Musk, the end-goal is to produce at least one Raptor per day in the near term – a necessity given that each Starship and Super Heavy booster pair will require at least 37 engines. To feasibly build a fleet of tens – let alone hundreds or thousands – of Starships and boosters, one engine per day is arguably the bare minimum required just for early orbital launch attempts and initial operations.

According to published schedules, Starship SN5’s first live wet dress rehearsal (WDR) and static fire tests could happen as early July 8th, with backups on the 9th and 10th. Coincidentally, SpaceX’s next orbital Falcon 9 launch is also expected on the 8th, meaning that both Starship and Falcon 9 could fire up more or less simultaneously.

California city weighs banning Elon Musk companies like Tesla and SpaceX

A resolution draft titled, “Resolution Ending Engagement With Elon Musk-Controlled Companies and To Encourage CalPERS To Divest Stock In These Companies,” alleges that Musk “has engaged in business practices that are alleged to include violations of labor laws, environmental regulations, workplace safety standards, and regulatory noncompliance.”

A California City Council is planning to weigh whether it would adopt a resolution that would place a ban on its engagement with Elon Musk companies, like Tesla and SpaceX.

The City of Davis, California, will have its City Council weigh a new proposal that would adopt a resolution “to divest from companies owned and/or controlled by Elon Musk.”

This would include a divestment proposal to encourage CalPERS, the California Public Employees Retirement System, to divest from stock in any Musk company.

A resolution draft titled, “Resolution Ending Engagement With Elon Musk-Controlled Companies and To Encourage CalPERS To Divest Stock In These Companies,” alleges that Musk “has engaged in business practices that are alleged to include violations of labor laws, environmental regulations, workplace safety standards, and regulatory noncompliance.”

It claims that Musk “has used his influence and corporate platforms to promote political ideologies and activities that threaten democratic norms and institutions, including campaign finance activities that raise ethical and legal concerns.”

If adopted, Davis would bar the city from entering into any new contracts or purchasing agreements with any company owned or controlled by Elon Musk. It also says it will not consider utilizing Tesla Robotaxis.

A staff report on the proposal claims there is “no immediate budgetary impact.” However, a move like this would only impact its residents, especially with Tesla, as the Supercharger Network is open to all electric vehicle manufacturers. It is also extremely reliable and widespread.

Regarding the divestment request to CalPERS, it would not be surprising to see the firm make the move. Although it voted against Musk’s compensation package last year, the firm has no issue continuing to make money off of Tesla’s performance on Wall Street.

The decision to avoid Musk companies will be considered this evening at the City Council meeting.

The report comes from Davis Vanguard.

It is no secret that Musk’s political involvement, especially during the most recent Presidential Election, ruffled some feathers. Other cities considered similar options, like the City of Baltimore, which “decided to go in another direction” after awarding Tesla a $5 million contract for a fleet of EVs for city employees.

Tesla has launched a new Model 3 financing deal in the United States that brings awesome savings. The deal looks to move more of the company’s mass-market sedan as it is the second-most popular vehicle Tesla offers, behind its sibling, the Model Y.

Tesla is now offering a 0.99% APR financing option for all new Model 3 orders in the United States, and it applies to all loan terms of up to 72 months.

It includes three Model 3 configurations, including the Model 3 Performance. The rate applies to:

  • Model 3 Premium Rear-Wheel-Drive
  • Model 3 Premium All-Wheel-Drive
  • Model 3 Performance

The previous APR offer was 2.99%.

Tesla routinely utilizes low-interest offers to help move vehicles, especially as the rates can help get people to payments that are more comfortable with their monthly budgets. Along with other savings, like those on maintenance and gas, this is another way Tesla pushes savings to customers.

The company had offered a similar program in China on the Model 3 and Model Y vehicles, but it had ended on January 31.

The Model 3 was the second-best-selling electric vehicle in the United States in 2025, trailing only the Model Y. According to automotive data provided by Cox, Tesla sold 192,440 units last year of the all-electric sedan. The Model Y sold 357,528 units.

Tesla hasn’t adopted Apple CarPlay yet for this shocking reason

Many Apple and iPhone users have wanted the addition, especially to utilize third-party Navigation apps like Waze, which is a popular alternative. Getting apps outside of Tesla’s Navigation to work with its Full Self-Driving suite seems to be a potential issue the company will have to work through as well.

Perhaps one of the most requested features for Tesla vehicles by owners is the addition of Apple CarPlay. It sounds like the company wants to bring the popular UI to its cars, but there are a few bottlenecks preventing it from doing so.

The biggest reason why CarPlay has not made its way to Teslas yet might shock you.

According to Bloomberg‘s Mark Gurman, Tesla is still working on bringing CarPlay to its vehicles. There are two primary reasons why Tesla has not done it quite yet: App compatibility issues and, most importantly, there are incredibly low adoption rates of iOS 26.

Tesla’s Apple CarPlay ambitions are not dead, they’re still in the works

iOS 26 is Apple’s most recent software version, which was released back in September 2025. It introduced a major redesign to the overall operating system, especially its aesthetic, with the rollout of “Liquid Glass.”

However, despite the many changes and updates, Apple users have not been too keen on the iOS 26 update, and the low adoption rates have been a major sticking point for Tesla as it looks to develop a potential alternative for its in-house UI.

It was first rumored that Tesla was planning to bring CarPlay out in its cars late last year. Many Apple and iPhone users have wanted the addition, especially to utilize third-party Navigation apps like Waze, which is a popular alternative. Getting apps outside of Tesla’s Navigation to work with its Full Self-Driving suite seems to be a potential issue the company will have to work through as well.

According to the report, Tesla asked Apple to make some changes to improve compatibility between its software and Apple Maps:

“Tesla asked Apple to make engineering changes to Maps to improve compatibility. The iPhone maker agreed and implemented the adjustments in a bug fix update to iOS 26 and the latest version of CarPlay.”

Gurman also said that there were some issues with turn-by-turn guidance from Tesla’s maps app, and it did not properly sync up with Apple Maps during FSD operation. This is something that needs to be resolved before it is rolled out.

There is no listed launch date, nor has there been any coding revealed that would indicate Apple CarPlay is close to being launched within Tesla vehicles.
