One week after the rocket was rolled from the factory to the launch pad, SpaceX appears to have successfully put Starship serial number 9 (SN9) through two routine pre-launch tests.

On December 22nd, significantly less than two weeks after Starship SN9 suffered a significant handling or production accident that caused it to tip several degrees and impact the walls of its production facility, SpaceX wrapped up speedy repairs and transported the rocket about 1.5 miles down the road.

In some combination of a minor miracle and Starship’s exceptionally sturdy design, the rocket – standing ~50 meters (~165 ft) tall and weighing around 75 to 100 metric tons (175,000-220,000 lb) – tipped sideways onto two of its four pre-installed flaps. Despite being subjected to off-nominal forces, the far stronger structural mechanisms connecting those flaps to Starship’s main airframe were seemingly unharmed and SpaceX was able to remove and replace the crumpled control surfaces mere days after the incident.

On December 28th, that work began in earnest with what is generally known as an ambient temperature pressure test, filling Starship SN9’s propellant tanks with benign air-temperature nitrogen gas. Used to check for leaks, verify basic vehicle valve and plumbing performance, and ensure a basic level of structural integrity, SN9 appeared to pass its ambient proof test without issue – albeit late in the window.

Testing wrapped up on Monday shortly after the ambient proof and was followed by the main event – a cryogenic proof test – a bit less than a day later on Tuesday. The exterior of Starship SN9 began to develop a coating of frost after SpaceX started loading its oxygen and methane tanks with liquid nitrogen around 2:30 pm CST (UTC-6). While used similarly to verify structural integrity like an ambient pressure test, a ‘cryo proof’ adds the challenge of thermal stresses to ensure that Starship can safely load, hold, and offload supercool liquids.

In SN9’s case, it’s unclear if SpaceX fully or only partially loaded the rocket’s main propellant tanks with liquid nitrogen, while a lack of frost at the tip of its nose implies that the Starship’s smaller liquid oxygen ‘header’ tank wasn’t filled as part of the test. Altogether, Starship should be capable of holding roughly 1200 metric tons of liquid nitrogen if fully loaded.

The lack of SN9’s LOx header tank participation in Tuesday cryo proof testing is intriguing on its own, as it implies that SpaceX will either perform a second cryo proof later this week or is confident enough in LOx header tank and transfer tube performance to forgo any testing. In the latter case, SpaceX would likely just use the build-up to Starship SN9’s first Raptor static fire test as a wet dress rehearsal (WDR) and a cryo proof for the smaller tank system.

According to NASASpaceflight’s managing editor, if Monday and Tuesday’s ambient and cryo proof tests were as uneventful and successful as they seemed, SpaceX may move directly on to triple-Raptor static fire preparations. In a first, Starship SN9 was transported to the launch pad last week with two of three central Raptor engines already installed and had that missing third engine installed within a few days of arrival. SN9 is also the first Starship to attempt its first proof tests with any Raptor – let alone three – installed.

If SpaceX does move directly from cryo proof testing to a three-engine static fire, that will mark another first for the Starship program and signal growing confidence and a desire for speedier preflight tests – both of which will help accelerate flight testing. As of now, SpaceX has yet to cancel a road closure scheduled on Wednesday, December 30th but it’s far more likely that a trio of 8 am to 5 pm CST closures requested on January 4th, 5th, and 6th will host Starship SN9’s first static fire attempt(s). According to NASASpaceflight.com, Starship SN9 is expected to attempt a 12.5 km (~7.8 mi) launch similar or identical to SN8’s as early as a few days after that static fire. Stay tuned for updates!

Tesla rolls out new life-saving feature for kids in Europe

On average, 37 children die every year from being left in vehicles unattended.

Tesla is rolling out a new life-saving feature in the European market, one that has been available in the United States for some time and can be considered potentially invaluable.

One of the most preventable causes of death for children is being left in cars unattended. On average, 37 children die every year after being left in hot vehicles. The cause of death is usually heatstroke, and it is incredibly avoidable.

Tesla rolls out new crucial safety feature aimed at saving children

However, there are instances where kids are left in vehicles and lose their lives, something that many companies have tried to fight with alerts and features of their own.

Tesla is one of them, as it has rolled out features like ultrasonic sensors to detect heartbeats, interior cameras to detect movement, and alerts to notify parents if they leave someone in the car.

A few months ago, Tesla rolled out a new feature called “Child Left Alone Detection” in the United States. It was described as:

“If an unattended child is detected, the vehicle will flash the exterior indicator lights, play an alert tone, and send a notification to your Tesla app. This will repeat at regular intervals until you return to your vehicle. Cabin data is processed locally and is not transmitted to Tesla.

This feature is enabled by default. To disable, go to Controls > Safety > Child Left Alone Detection.”

This feature was only rolled out in the U.S. at the time. It is now making its way to the European market, according to Not a Tesla App, which detected the rollout in the 2025.32.6 software update.

The rollout of this feature could specifically change many unfortunate situations. For many of us, it seems hard to think about leaving something as precious as another human life in a hot car. Many of us won’t leave our vehicles without our cell phones, so it seems unlikely that someone would do it without a child.

Tesla gets another NHTSA probe, this time related to door handles

“Although Tesla vehicles have manual door releases inside of the cabin, in these situations, a child may not be able to access or operate the releases even if the vehicle’s driver is aware of them.”

Tesla is facing another investigation into its vehicles by the National Highway Traffic Safety Administration (NHTSA), this time related to an issue with its door handles.

In a new Open Investigation named “Electronic door handles become inoperative,” the NHTSA says that it has received nine complaints from owners of the 2021 Tesla Model Y stemming from “an inability to open doors.”

These issues were reported after “parents exited their vehicle after a drive cycle in order to remove a child from the pack seat or placing a child in the back seat before starting a drive cycle.” Parents said they were “unable to reopen a door to regain access to the vehicle.”

Tesla door handles become unlikely hero as they stump road rager

Four of the nine complaints ended with having to break a window to regain access to the cabin.

The NHTSA goes on to explain that, while Teslas do have a manual door release inside the cabin, a child may not be able to access it:

“Although Tesla vehicles have manual door releases inside of the cabin, in these situations, a child may not be able to access or operate the releases even if the vehicle’s driver is aware of them. As a result, in these instances, an occupant who remains inside a vehicle in this condition may be unable to be rapidly retrieved by persons outside of the vehicle.”

It appears that the agency is attributing the issue to a low voltage in the vehicle’s 12V DC battery. This would mean there needs to be some sort of notification to the driver that the battery is running low on power and should be replaced to avoid this issue.

The NHTSA estimates that 174,290 vehicles are potentially impacted by this issue. It plans to assess the scope and severity of the condition, the agency says. The NHTSA also wants to see what approach Tesla uses to supply power to door locks and the reliability of the applicable power supplies.

Tesla won’t implement strange Grok character as Musk dispels rumor

It is nice to see that Tesla is not forcing this kind of character upon owners of their vehicles, especially considering that many people had a real problem with it.

Tesla is not going to implement a strange character as a Grok assistant in its vehicles, as CEO Elon Musk dispelled the rumor, which seemed to truly invoke some quite polarizing reactions.

Yesterday, there was some controversy within the Tesla community as rumors of a Grok assistant, named Mūn (pronounced like Moon), being implemented into the vehicles started to circulate.

It had some legitimacy. It was initially posted by an employee, and it appeared to be a relatively confirmed development.

However, it really did rub some people the wrong way. Mūn was an Anime-style female dressed in promiscuous clothing, so it was not everyone’s style, and I’m sure not everyone’s significant other’s cup of tea. It seemed a very strange decision to add it, especially considering that, at the time, there was no confirmation to dispel the arrival of the Grok assistant.

That was until Tesla CEO Elon Musk stepped in to put the speculation to bed once and for all.

It was somewhat strange that this type of issue arose in the first place, but given that it was initially released by an employee, the entire situation is self-explanatory.

It is nice to see that Tesla is not forcing this kind of character upon owners of their vehicles, especially considering that many people had a real problem with it. Many owners did not shy away from the fact that they would like the option to opt out:

For now, Grok remains a part of Tesla vehicles, and personally, it is very nice to have in my Model Y to answer some quick questions I might have or even to entertain some people in the car.

Nevertheless, I am relieved I won’t have this character forced upon me in my vehicle.
