After a brisk week of no fewer than three lengthy static fire tests, SpaceX has effectively confirmed that a critical vibration-related fault was solved, delivering the company’s latest completed Raptor engine to Boca Chica, Texas earlier today.

SpaceX technicians are now in the process of installing the engine – believed to be Raptor SN06 – on Starhopper, a low-fidelity prototype meant to act as a sort of flying testbed for Starship technologies and a mobile test stand for Raptor test fires. According to SpaceX CEO Elon Musk, if Raptor SN06 is installed, successfully checks out, and supports Starhopper’s first untethered hover test within the next 3-7 days, he will deliver an updated presentation on SpaceX’s Starhip/Super Heavy launch vehicle and (hopefully) the company’s plans for the Moon and Mars around the end of July.

This Raptor is the third to be installed on Starhopper. The first engine (SN02) was installed in March 2019 and became the first Raptor to ignite as part of a vehicle meant to eventually fly. During a duo of more or less successful test fires, Starhopper strained against its tethers, lifting a few inches off the ground. Although it did technically mark Starhopper’s inaugural hop, Raptor SN02 also suffered damage during the tests that demanded its removal.

Starhopper’s first static fire test with Raptor SN02 occurred on April 3rd, 2019.

As recently noted by observant fans after Musk revealed that SpaceX had been dealing with a “600 Hz” vibration issue, the horn-like noise during shutdown actually happens to be in the 600 Hz range, with an additional spike at 300 Hz a likely sign of an issue with acoustic and/or mechanical resonance. With SN06, SpaceX engineers and test/production technicians have managed to rapidly implement a fix for that undesirable resonance, powering through several successful static fires with durations as high as 80+ seconds, approaching the propellant storage limits of SpaceX’s McGregor test facilities.

Raptor SN04?

Shortly after its static fire tests in Boca Chica, Raptor SN02 was removed. According to a source familiar with the test process, the engine was brought up to McGregor, TX and repaired before SpaceX technicians – urged by CEO Elon Musk – effectively ran the engine until it failed catastrophically. Some two months after its removal (early June), a new Raptor engine – this time believed to be Raptor SN04, effectively an inert test article – was installed on Starhopper for a handful of days.

SN04 was exclusively used to check fitment and verify Raptor’s thrust vector control (TVC) gumball capabilities – quite successfully, by all appearances. A few days after installation, it was removed and shipped elsewhere. Subsequently, Raptor SN05 was tested in McGregor with the hopes that it would be able to support the first Starhopper hover tests, but the vibration issue described by Musk caused damage or at least killed confidence that the engine (a single point of failure on Starhopper) was reliable enough to support hover tests.

Raptor SN06 thus entered our story, arriving at McGregor around July 4th. SpaceX’s world-class team of engineers and technicians demonstrated their famous speed and agility, firing up SN06 less than 24 hours after its arrival. This initial test showed nothing out of order and was followed by no less than 3-4 30-80-second static fire tests, all of which were more or less successful. Per Musk, things were looking good as of July 8th, and Raptor’s July 11th arrival at Boca Chica is a foolproof confirmation that the engine is healthy and ready for the Raptor family’s first true flight.

Tesla launches Cybertruck orders in a new market with a catch

Tesla is launching Cybertruck orders in a new market, but there’s a bit of a catch.

The Cybertruck was launched in the Middle East earlier this year, as Tesla launched the ability to place a reservation for the all-electric pickup in the United Arab Emirates. It would be the first market outside of North America that would have the ability to place an order for the Cybertruck.

Tesla confirms Cybertruck will make its way out of North America this year

Other markets where the vehicle has been widely requested, like Europe and Asia, have still not approved the vehicle to be sold to the public, mostly because of size and design restrictions.

However, in the UAE, Tesla is opening up the ability for those who placed reservations for the vehicle to finally put in their order. The Order Configurator is only available to those who have already placed a reservation; it is not yet available to the public.

Tesla said it would open up the public online configurator across the Middle East in the coming weeks:

The UAE is not the only country that will have access to the Cybertruck, as fans in other Middle Eastern countries will also be able to place orders soon. Tesla announced back in April that Saudi Arabia and Qatar would also have Cybertruck deliveries.

These vehicles will be built at Tesla’s Gigafactory Texas plant just outside of Austin, as Gigafactory Berlin and Gigafactory Shanghai, two factories located in the same hemisphere as the Middle East, do not have established lines for Cybertruck production.

As for the other markets, Tesla CEO Elon Musk has hinted that the company could develop a smaller Cybertruck for those markets, as he admitted that in the long term, it likely made sense to build a more compact version for regions where roads are traditionally tighter.

There has been no evidence of Tesla developing this more compact version, but it could eventually happen.

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.
