SpaceX is set to launch its eighth test flight of the Starship rocket this Friday. Ahead of the most recent test in what could be the most revolutionary spaceflight program since NASA’s Apollo, SpaceX is clearing the air about what went wrong during its previous test flight, which resulted in the loss of the second stage during its ascension.

On January 16, SpaceX successfully launched Starship while also completing its second successful catch of the lower-stage booster.

However, the flight did not go as smoothly as initially anticipated, as the company lost Starship’s upper stage roughly eight minutes and twenty seconds into flight.

Now, the company is clarifying what happened that led to the demise of the upper stage, which SpaceX has identified with the recognition of “flashes” that occurred after vehicle separation.

SpaceX says that a flash was observed roughly two minutes into its burn after vehicle separation. The flash, along with sensors that was a pressure rise in the attic, indicated a leak:

“Approximately two minutes into its burn, a flash was observed in the aft section of the vehicle near one of the Raptor vacuum engines. This aft section, commonly referred to as the attic, is an unpressurized area between the bottom of the liquid oxygen tank and the aft heatshield. Sensors in the attic detected a pressure rise indicative of a leak after the flash was seen.”

This was not the only flash that was observed. Two minutes after the first, another flash was seen, but this one was followed by sustained fires in the attic. These fires caused Starship’s engines to perform a controlled shutdown:

“These eventually caused all but one of Starship’s engines to execute controlled shut down sequences and ultimately led to a loss of communication with the ship. Telemetry from the vehicle was last received just over eight minutes and 20 seconds into flight.”

SpaceX clarified that Starship was destroyed and communication with the ship was lost before it was able to initiate any destruct rules for its Autonomous Flight Safety System. The company said this was “fully healthy when communication was lost.”

It went on to say that the “most probable root cause” of the loss was likely due to an environment not seen during testing:

“The most probable root cause for the loss of ship was identified as a harmonic response several times stronger in flight than had been seen during testing, which led to increased stress on hardware in the propulsion system. The subsequent propellant leaks exceeded the venting capability of the ship’s attic area and resulted in sustained fires.”

Nevertheless, Starship will launch for the eighth time soon, with CEO Elon Musk noting that the most likely date will be Friday. This could be the second of potentially 25 Starship launches planned for 2025.

Tesla (NASDAQ:TSLA) has gained fresh institutional support, with Nomura Asset Management expanding its position in the automaker. 

Nomura boosted its Tesla holdings by 4.2%, adding 47,674 shares and bringing its total position to more than 1.17 million shares valued at roughly $373.6 million. The move makes Tesla Nomura’s 10th-largest holding at about 1% of its entire portfolio.

Institutional investors and TSLA

Nomura’s filing was released alongside several other fund updates. Brighton Jones LLC boosted its holdings by 11.8%, as noted in a MarketBeat report, and Revolve Wealth Partners lifted its TSLA position by 21.2%. Bison Wealth increased its Tesla stake by 52.2%, AMG National Trust Bank increased its position in shares of Tesla by 11.8%, and FAS Wealth Partners increased its TSLA holdings by 22.1%. About 66% of all outstanding Tesla shares are now owned by institutional investors.

The buying comes shortly after Tesla reported better-than-expected quarterly earnings, posting $0.50 per share compared with the $0.48 consensus. Revenue reached $28.10 billion, topping Wall Street’s $24.98 billion estimate. Despite the earnings beat, Tesla continues to trade at a steep premium relative to peers, with a market cap hovering around $1.34 trillion and a price-to-earnings ratio near 270.

Recent insider sales

Some Tesla insiders have sold stock as of late. CFO Vaibhav Taneja sold 2,606 shares in early September for just over $918,000, reducing his personal stake by about 21%. Director James R. Murdoch executed a far larger sale, offloading 120,000 shares for roughly $42 million and trimming his holdings by nearly 15%. Over the past three months, Tesla insiders have collectively sold 202,606 shares valued at approximately $75.6 million, as per SEC disclosures.

Tesla is currently entering its next phase of growth, and if it is successful, it could very well become the world’s most valuable company as a result. The company has several high-profile projects expected to be rolled out in the coming years, including Optimus, the humanoid robot, and the Cybercab, an autonomous two-seater with the potential to change the face of roads across the globe.

Tesla rolls out fresh Supercharger pricing strategy to more locations

Live Pricing aimed to resolve some of the shortcomings of the off-peak and on-peak system, aiming to keep prices low and base them on current utilization instead of a set time when prices change.

Tesla has rolled out a fresh Supercharger pricing strategy to more locations, as it confirmed it has added 550 additional sites in the United States to its “Live Pricing” strategy.

Live Pricing for Superchargers launched back in May, and was the company’s latest strategy to keep charging your EV cheap, affordable, and easy to understand.

Tesla has adjusted its pricing strategy at Superchargers several times over the past few years, with the most notable being the 2020 introduction of off-peak and on-peak Supercharging rates.

Live Pricing aimed to resolve some of the shortcomings of the off-peak and on-peak system, aiming to keep prices low and base them on current utilization instead of a set time when prices change.

Tesla explained the program when it launched:

“We are piloting on-peak and off-peak pricing based on live Supercharger utilization rather than estimations. The average price remains unchanged, but this live feedback loop improves accuracy. This corrects off-peak pricing during times of congestion, or on-peak pricing when Superchargers are plentiful. You’ll always see the price before your session begins, and prices do not change mid-session. A small-scale pilot is launching at 10 sites and will expand based on feedback and success.”

The initial rollout only included Superchargers in California, but it was not all of them, only a handful instead. Tesla was attempting to launch it in a very controlled manner by using a Pilot Program that would iron out all the early bugs and potential issues it might run into.

However, the company expanded the program by launching it at an additional 550 sites in California, New Jersey, New York, Florida, and Illinois:

The price you pay is locked in when you plug in, so if the Supercharger station you are charging at becomes more crowded and the program bumps up the rates because of high utilization rates, you will still receive the cheaper price that was enabled when you arrived.

Tesla Robotaxi was just spotted in a new state for the first time

The company is still attempting to expand and has explicitly stated that it plans to offer rides in Nevada, Arizona, and Florida in the near future. However, a pair of Robotaxi mules, fitted with LiDAR equipment for ground truth validation, was spotted in a new region for the first time.

Tesla Robotaxi mules were spotted in a new state for the first time as the company plans to expand the ride-sharing service to new areas of the United States in the coming months.

Tesla is offering Robotaxi rides in Austin already, where nobody is present in the driver’s seat except for on freeway routes. In California, Tesla refers to its platform as a ride-hailing suite, and a “Safety Monitor” is present in the driver’s seat at all times, but the vehicle operates on Full Self-Driving.

The company is still attempting to expand and has explicitly stated that it plans to offer rides in Nevada, Arizona, and Florida in the near future. However, a pair of Robotaxi mules, fitted with LiDAR equipment for ground truth validation, was spotted in a new region for the first time.

Over the weekend, Tesla Robotaxi mules were spotted in Enola, Pennsylvania, just about ten minutes from downtown Harrisburg:

Enola is situated to the northwest of Harrisburg, Pennsylvania’s State Capitol. Interestingly, you’d expect Tesla to be testing these types of vehicles in other, more populated areas; Philadelphia is about two hours East, and Pittsburgh is about three hours west. State College is about an hour North of Enola.

Looking at the location of where the vehicles were spotted tells an interesting story, as Enola, located right outside of the State Capitol, could be a move to nudge legislators to consider looking at some of the laws that deal with driverless and autonomous vehicle operation.

Pennsylvania’s Act 130 of 2022 and subsequent guidelines permit the testing of driverless vehicles in the Commonwealth, but PennDOT requires a permit from Tesla or any other company that wants to operate a ride-hailing service in PA.

It’s also important to note that the cars could have simply been stopping through, as they were spotted at a Supercharger location along Interstate 81, which spans from Tennessee to New York.

It is not to say the vehicles are testing along the entire route, but likely a segment of it. The fact that they were spotted in Pennsylvania does bode well for Tesla’s expansion efforts moving forward.
