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 completes second catch of lower stage, but loses Starship

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.

Elon Musk doubles down on Tesla Cybercab timeline once again

“Cybercab, which has no pedals or steering wheel, starts production in April,” Musk said.

CEO Elon Musk doubled down once again on the timeline of production for the Tesla Cybercab, marking yet another example of the confidence he has in the company’s ability to meet the aggressive timeline for the vehicle.

It is the third time in the past six months that Musk has explicitly stated Cybercab will enter production in April 2026.

On Monday morning, Musk reiterated that Cybercab will enter its initial manufacturing phase in April, and that it would not have any pedals or a steering wheel, two things that have been speculated as potential elements of the vehicle, if needed.

Musk has been known to be aggressive with timelines, and some products have been teased for years and years before they finally come to fruition.

One of perhaps the biggest complaints about Musk is the fact that Tesla does not normally reach the deadlines that are set: the Roadster, Semi, and Unsupervised Full Self-Driving suite are a few of those that have been given “end of this year” timelines, but have not been fulfilled.

Nevertheless, many are able to look past this as part of the process. New technology takes time to develop, but we’d rather not hear about when, and just the progress itself.

However, the Cybercab is a bit different. Musk has said three times in the past six months that Cybercab will be built in April, and this is something that is sort of out of the ordinary for him.

In December 2025, he said that Tesla was “testing the production system” of the vehicle and that “real production ramp starts in April.

Elon Musk shares incredible detail about Tesla Cybercab efficiency

On January 23, he said that “Cybercab production starts in April.” He did the same on February 16, marking yet another occasion that Musk has his sights set on April for initial production of the vehicle.

Musk has also tempered expectations for the Cybercab’s initial production phase. In January, he noted that Cybercab would be subjected to the S-curve-type production speed:

“…initial production is always very slow and follows an S-curve. The speed of production ramp is inversely proportionate to how many new parts and steps there are. For Cybercab and Optimus, almost everything is new, so the early production rate will be agonizingly slow, but eventually end up being insanely fast.”

Cybercab will be a huge part of Tesla’s autonomous ride-sharing plans moving forward.

Tesla owners explore potential FSD pricing options as uncertainty looms

We asked Tesla owners what the company should price Full Self-Driving moving forward, as now it’s going to be subscription-based. There were some interesting proposals.

Tesla is starting the process of removing the ability to purchase the Full Self-Driving suite outright, as it pulled the purchase option in the United States over the weekend.

However, there has been some indication by CEO Elon Musk that the price of the subscription will increase as the suite becomes more robust. But Tesla finds itself in an interesting situation with this: the take rate for Full Self-Driving at $99 per month is about 12 percent, and Musk needs a significant increase in this rate to reach a tranche in his new compensation package.

This leaves Tesla and owners in their own respective limbos: Tesla needs to find a price that will incentivize consumers to use FSD, while owners need Tesla to offer something that is attractive price-wise.

Price Reduction

Although people are willing to pay the $99 per month for the FSD suite, it certainly is too high for some owners. Many suggested that if Tesla would back down the price to $49, or somewhere around that region, many owners would immediately subscribe.

Others suggested $69, which would make a lot of sense considering Musk’s obsession with that number.

Different Pricing for Supervised and Unsupervised

With the release of the Unsupervised version of Full Self-Driving, Tesla has a unique opportunity to offer pricing for different attention level requirements.

Unsupervised Full Self-Driving would be significantly more expensive, but not needed by everyone. Many people indicate they would still like to drive their cars manually from time to time, but others said they’d just simply be more than okay with only having Supervised FSD available in their cars.

Time-Based Pricing

Tesla could price FSD on a duration-based pricing model, including Daily, Weekly, Monthly, and Annual rates, which would incentivize longer durations with better pricing.

Annually, the rate could be $999 per year, while Monthly would stay at $99. However, a Daily pass of FSD would cost somewhere around $10, while a $30 per week cost seems to be ideal.

These all seem to be in line with what consumers might want. However, Tesla’s attitude with FSD is that it is the future of transportation, and with it offering only a Monthly option currently, it does not seem as if it will look as short-term as a Daily pass.

Tiered Pricing

This is perhaps the most popular option, according to what we’ve seen in comments and replies.

This would be a way to allow owners to pick and choose which FSD features they would like most and pay for them. The more features available to you, the more it costs.

For example, if someone only wanted Supervised driving and Autopark, it could be priced at $50 per month. Add in Summon, it could be $75.

This would allow people to pick only the features they would use daily.

Tesla leaves a single loophole to purchase Full Self-Driving outright

Tesla has left a single loophole to purchase Full Self-Driving outright. On Sunday, the option officially disappeared from the Online Design Studio in the United States, as Tesla transitioned to a Subscription-only purchasing plan for the FSD suite.

However, there is still one way to get the Full Self-Driving suite in an outright manner, which would not require the vehicle owner to pay monthly for the driver assistance program — but you have to buy a Model S or Model X.

Months ago, Tesla launched a special “Luxe Package” for the Model S and Model X, which included Full Self-Driving for the life of the vehicle, as well as free Supercharging at over 75,000 locations, as well as free Premium Connectivity, and a Four-Year Premium Service package, which includes wheel and tire protection, windshiel protection, and recommended maintenance.

It would also be available through the purchase of a Cyberbeast, the top trim of the Cybertruck lineup.

This small loophole would allow owners to avoid the monthly payment, but there have been some changes in the fine print of the program, as Tesla has added that it will not be transferable to subsequent vehicle owners or to another vehicle.

This goes for the FSD and the Supercharging offers that come with the Luxe Package.

For now, Tesla still has the Full Self-Driving subscription priced at $99 per month. However, that price is expected to increase over the course of some time, especially as its capabilities improve. Tesla seems to be nearing Unsupervised FSD based on Musk’s estimates for the Cybercab program.

There is the potential that Tesla offers both Unsupervised and Supervised FSD for varying prices, but this is not confirmed.

In other countries, Tesla has pushed back the deadline to purchase the suite outright, as in Australia, it has been adjusted to March 31.
