SpaceX has been unable to catch a break in the last few weeks and CEO Elon Musk says that a Starship Raptor engine test was delayed twice in one day by minor hardware bugs and damage caused by Hurricane Hanna.

Although it quickly devolved into a tropical storm and largely missed the southernmost tip of Texas, where SpaceX has built its Starship factory and test facilities, Hanna caused significant damage just a few dozen miles to the north. Above all else, the flooding caused by Hanna has by far been the worst part of the storm. Boca Chica managed to dodge the bulk of that element but was still hit by heavy rain that lasted for a day or two, drenching everything that wasn’t covered and nearly flooding the only access road.

According to Musk, an unspecified “connector” related to Starship SN5 or the pad supporting it was damaged by Hanna’s glancing encounter with SpaceX’s facilities. The connector was ultimately fixed around 7-8 pm CDT per unofficial webcasts showing technicians working around the rocket after they returned to the pad, but SpaceX’s test window technically closed at 8 pm CDT (01:00 UTC).

Nevertheless, SpaceX must have been able to work with local sheriffs to extend that road closure into the night, and – as promised by CEO Elon Musk – testing restarted around 9:30 pm CDT. About an hour and a half later, Starship SN5 appeared to make it all the way through a partial wet dress rehearsal before its Raptor engine test fire was aborted a second time. Based on four static fires completed by Starship SN4 in May 2020, the rocket could have been just a few minutes away from ignition.

According to Musk, Starship SN5’s fuel (methane) “spin valve” – presumably a valve that opens to allow methane gas to spin up Raptor’s fuel turbopump – failed to open when it was supposed to. To ensure Raptor’s health after three inactive weeks spent installed on Starship out in the elements, SpaceX likely planned what is known as a “spin prime” test directly prior to the static fire. If Raptor successfully spun up its turbopumps, SpaceX would proceed directly into static fire operations without having to detank Starship.

During SN5’s second July 27th static fire attempt, Raptor was unable to start that spin prime test, forcing SpaceX to stand down to diagnose and fix the problem. Musk says that SpaceX will attempt to static fire Starship SN5 again tomorrow (July 28th) – assuming the issue can be quickly rectified.

Musk further noted that some “odd…behavior” was observed in the hydraulic pump powering Raptor SN27’s thrust vector control (TVC). Used to steer a rocket engine, Raptor doesn’t technically need functioning TVC to perform a static fire test on the ground, but it’s an issue that will have to be completely fixed before Starship SN5 is allowed to attempt its first flight test. If July 28th finally sees SN5 successfully ignite its Raptor engine, there’s a chance – however slim – that SpaceX will be able to turn the Starship around for its first hop just a few days later.

Tesla clears the air on Cybertruck ‘deactivation’ video that is obviously fake

Tesla has cleared the air on the viral video, stating it is fake.

Tesla has cleared the air regarding a video that has been circulating, where the owner claims his Cybertruck was “deactivated” by the company while he was driving.

The video was shared on X and showed a driver pulled over on the side of the road, claiming his Cybertruck had been deactivated by Tesla in the middle of traffic. It is very obviously fake to those who know the company, but these kinds of things have a tendency to pick up steam.

The video shows a screen that says:

“Tesla Cybertruck De-Activated. Critical Issue Detected | Contact Customer Service, Comply with Cease & Desist to Re-Activate. Update Failed, Return to Dealer.”

The same person who posted the video also shared an image of what appears to be a Cease and Desist letter from Tesla, but it is also likely fake:

The company finally responded to the video on Monday afternoon, stating that the video is, in fact, fake, reiterating that it will not disable vehicles remotely for any reason.

It is a shame that these types of things happen, especially as people are prone to believe anything they see on the internet. As there is so much misinformation circulating surrounding Tesla and its CEO Elon Musk, it is no surprise that someone would leverage the situation for their own benefit.

If that Cease and Desist letter is not real, perhaps the next one might be. These types of things can truly cause damage to a company’s reputation, and someone getting an idea that Tesla would remotely deactivate a car could prevent them from buying one.

Elon Musk is stepping up for Tesla Service in a big way

Elon Musk has stepped up to resolve a handful of customer issues regarding vehicle service.

Elon Musk is stepping up to help customers in a big way, especially when they are having issues with Tesla’s Service.

Perhaps one of the biggest advantages Tesla owners have is access to Musk through X, his social media platform. Over the years, we’ve seen Tesla add features, refine its cars’ performance, and more, all through asking Musk directly through a post.

Now, Musk is stepping up in another way by resolving a few Service complaints that customers had.

The first occurred last week when a recall on a Tesla battery was not honored by Service. The company sought $30,000 for a replacement and labor, which was not right. Musk responded that he would personally investigate the matter. The vehicle was fixed at no cost as it was a recall, and was ready for pickup the next day.

It also revealed a new strategy Tesla is using to combat service communication issues:

Tesla creates clever solution to simplify and improve its Service

The next occurred with a Cybertruck owner who was in Japan. Their car was parked at an airport in the U.S. and had lost a vast majority of its state of charge, leaving them just fifty miles of range at the time.

Musk reached out to the owner and said Service will take care of the car and will investigate the cause of the battery drain:

There are not too many companies out there where the CEO will get involved with individual issues like these. It’s pretty exclusive to Tesla, as Musk has commonly stepped up to resolve complaints with vehicles or to confront features that some owners might find useful.

Service has been a weak point of the company for some time, but it has worked to refine and resolve customer complaints by building more Service Centers across the world that can handle these issues.

Tesla CEO Elon Musk confirms Robotaxi is opening to the public: here’s when

Anyone will be able to request a Tesla Robotaxi in September, Elon Musk said this morning.

Tesla CEO Elon Musk has confirmed that the company’s Robotaxi platform is opening to the public, and he even gave a timeline for when anyone will be able to access one for a ride.

Tesla’s Robotaxi platform launched to a small group on June 22 in Austin, Texas. The company has continued to expand the number of riders and its geofence over the past month and a half.

Tesla officially launches Robotaxi service with no driver

Additionally, it launched rides in the Bay Area of California, but it differs slightly, as the Texas Robotaxi platform does not utilize a Safety Monitor in the driver’s seat. In California, the monitor sits in the driver’s seat.

As the geofence, service areas, and testing populations expand, Tesla fans are awaiting their elusive emails that enable their ability to use the Robotaxi platform. It now seems that the email will come soon, as Musk said Tesla will open up public access to Robotaxi next month:

Tesla has been prioritizing safety over anything else with the launch of the Robotaxi platform, which is why it has been slow to push invitations to new riders. It is confident in the abilities of the platform and its Full Self-Driving suite, which has been proven with data.

However, even a single accident could set Tesla back years in terms of its development of self-driving cars. It is not a risk it is willing to take.

Musk said during the recent Q2 Earnings Call:

“We need to make sure it works when the vehicles are fully under our control. It’s kind of one step at a time here. We don’t want to jump the gun. As I said, we’re being paranoid about safety. But I guess next year is I’d say confidently next year. I’m not sure when next year, but confidently next year, people would be able to add or subtract their car to the Tesla, Inc. fleet.”

As the platform will expand in Austin and the Bay Area for anyone, Tesla still continues to reiterate that Robotaxi will be available for everyone sometime next year, as Musk said in the quote above.

Things will continue to improve over time, and Tesla will likely expand its geofence in both regions in the coming weeks. It has already done that in Austin twice, with about a doubling in size occurring both times.
