SpaceX reveals new details on Starship’s third test flight
SpaceX has revealed some new information regarding the third test flight of its massive Starship rocket.
The flight, which took place from Starbase, Texas, yesterday morning at 8:25 am CT, capitalized on previous test flights and accomplished a host of new objectives.
All 33 Raptor engines lit in a staggered sequence, and once throttled up, the world’s biggest rocket took flight for the third time.

As Starship climbed into the South Texas skies, the 33 engines continued to operate nominally until the hot stage separation, in which 30 of Super Heavy’s engines shut down as Starship lit its 3 sea-level and 3 vacuum Raptor engines and continued to space.
For the first time, the Super Heavy first stage, Booster 10, successfully performed a boost back burn and aimed for a splashdown just East of the launch pad in the Gulf of Mexico. According to the data displayed on the webcast, the booster reached a peak speed of 5750 km/h and an altitude of 106 km.

Unlike the Falcon 9, the Super Heavy is so big it does not need to do an entry burn however in one of the last bits of data available on the webcast, it showed the booster attempted to begin its landing burn around 1 km in altitude with only 3 engines lighting and 2 shutting off almost immediately after.
SpaceX has since confirmed that Booster 10 experienced a rapid unscheduled disassembly just 462 meters above the water’s surface, and it is likely that what remained of the booster hit the water at nearly the speed of sound.
While Booster 10 was meeting its fate in the Gulf of Mexico following a great performance, Ship 28 continued to burn all 6 of its Raptor engines and completed its first full-duration burn, inserting itself into its proper sub-orbital trajectory.

Ship 28 then began its coast phase and started a series of tests. The payload bay door, aka pez door, designed to eventually eject the full-size Starlink satellites, was first commanded to open 12 minutes into the flight. SpaceX has yet to confirm whether it managed to fully open/close the door. At 30:18 into the mission, the door appears to have dislodged into the payload bay, and we no longer got any live views inside the ship.
The next task was to re-light the first-ever Raptor engine in space, but due to the vehicle’s roll rates, SpaceX decided to postpone this until a future flight.
Ship 28 then began atmospheric entry, but the ship seemed to be partially out of control with the spin and eventually began to build up plasma. The heat shield was only half exposed, and the rest was bare stainless steel, taking the brunt of the forces of re-entry.

Thanks to Starlink terminals on board, SpaceX was able to provide incredible live views from a camera located on one of Starship’s flaps. The plasma began as a faint pink glow before rapidly growing and enveloping the vehicle while still maintaining a good data connection which has never before been possible.
Overall, SpaceX made many great advancements on this third test flight and will look to complete all of these on the fourth test flight, including a smooth splashdown of the Super Heavy booster and successful re-entry through the atmosphere for Starship.
When do you think the 4th test flight will occur, and will they fix the issues encountered during flight 3?

Tesla has officially launched public Robotaxi rides in Austin, Texas, without a Safety Monitor in the vehicle, marking the first time the company has removed anyone from the vehicle other than the rider.
The Safety Monitor has been present in Tesla Robotaxis in Austin since its launch last June, maintaining safety for passengers and other vehicles, and was placed in the passenger’s seat.
Tesla planned to remove the Safety Monitor at the end of 2025, but it was not quite ready to do so. Now, in January, riders are officially reporting that they are able to hail a ride from a Model Y Robotaxi without anyone in the vehicle:

Tesla started testing this internally late last year and had several employees show that they were riding in the vehicle without anyone else there to intervene in case of an emergency.
Tesla has now expanded that program to the public. It is not active in the entire fleet, but there are a “few unsupervised vehicles mixed in with the broader robotaxi fleet with safety monitors,” Ashok Elluswamy said:
Robotaxi rides without any safety monitors are now publicly available in Austin.
Starting with a few unsupervised vehicles mixed in with the broader robotaxi fleet with safety monitors, and the ratio will increase over time. https://t.co/ShMpZjefwB

Tesla Robotaxi goes driverless as Musk confirms Safety Monitor removal testing
The Robotaxi program also operates in the California Bay Area, where the fleet is much larger, but Safety Monitors are placed in the driver’s seat and utilize Full Self-Driving, so it is essentially the same as an Uber driver using a Tesla with FSD.
In Austin, the removal of Safety Monitors marks a substantial achievement for Tesla moving forward. Now that it has enough confidence to remove Safety Monitors from Robotaxis altogether, there are nearly unlimited options for the company in terms of expansion.
While it is hoping to launch the ride-hailing service in more cities across the U.S. this year, this is a much larger development than expansion, at least for now, as it is the first time it is performing driverless rides in Robotaxi anywhere in the world for the public to enjoy.
Tesla has scheduled its Earnings Call for Q4 and Full Year 2025 for next Wednesday, January 28, at 5:30 p.m. EST, and investors are already preparing to get some answers from executives regarding a wide variety of topics.
The company accepts several questions from retail investors through the platform Say, which then allows shareholders to vote on the best questions.
Tesla does not answer anything regarding future product releases, but they are willing to shed light on current timelines, progress of certain projects, and other plans.
There are five questions that range over a variety of topics, including SpaceX, Full Self-Driving, Robotaxi, and Optimus, which are currently in the lead to be asked and potentially answered by Elon Musk and other Tesla executives:
- You once said: Loyalty deserves loyalty. Will long-term Tesla shareholders still be prioritized if SpaceX does an IPO?
- Our Take – With a lot of speculation regarding an incoming SpaceX IPO, Tesla investors, especially long-term ones, should be able to benefit from an early opportunity to purchase shares. This has been discussed endlessly over the past year, and we must be getting close to it.
- When is FSD going to be 100% unsupervised?
- Our Take – Musk said today that this is essentially a solved problem, and it could be available in the U.S. by the end of this year.
- What is the current bottleneck to increase Robotaxi deployment & personal use unsupervised FSD? The safety/performance of the most recent models or people to monitor robots, robotaxis, in-car, or remotely? Or something else?
- Our Take – The bottleneck seems to be based on data, which Musk said Tesla needs 10 billion miles of data to achieve unsupervised FSD. Once that happens, regulatory issues will be what hold things up from moving forward.
- Regarding Optimus, could you share the current number of units deployed in Tesla factories and actively performing production tasks? What specific roles or operations are they handling, and how has their integration impacted factory efficiency or output?
- Our Take – Optimus is going to have a larger role in factories moving forward, and later this year, they will have larger responsibilities.
- Can you please tie purchased FSD to our owner accounts vs. locked to the car? This will help us enjoy it in any Tesla we drive/buy and reward us for hanging in so long, some of us since 2017.
- Our Take – This is a good one and should get us some additional information on the FSD transfer plans and Subscription-only model that Tesla will adopt soon.
Tesla will have its Earnings Call on Wednesday, January 28.
Elon Musk shared an incredible detail about Tesla Cybercab’s potential efficiency, as the company has hinted in the past that it could be one of the most affordable vehicles to operate from a per-mile basis.
ARK Invest released a report recently that shed some light on the potential incremental cost per mile of various Robotaxis that will be available on the market in the coming years.
The Cybercab, which is detailed for the year 2030, has an exceptionally low cost of operation, which is something Tesla revealed when it unveiled the vehicle a year and a half ago at the “We, Robot” event in Los Angeles.
Musk said on numerous occasions that Tesla plans to hit the $0.20 cents per mile mark with the Cybercab, describing a “clear path” to achieving that figure and emphasizing it is the “full considered” cost, which would include energy, maintenance, cleaning, depreciation, and insurance.
Probably true
— Elon Musk (@elonmusk) January 22, 2026
ARK’s report showed that the Cybercab would be roughly half the cost of the Waymo 6th Gen Robotaxi in 2030, as that would come in at around $0.40 per mile all in. Cybercab, at scale, would be at $0.20.

This would be a dramatic decrease in the cost of operation for Tesla, and the savings would then be passed on to customers who choose to utilize the ride-sharing service for their own transportation needs.
The U.S. average cost of new vehicle ownership is about $0.77 per mile, according to AAA. Meanwhile, Uber and Lyft rideshares often cost between $1 and $4 per mile, while Waymo can cost between $0.60 and $1 or more per mile, according to some estimates.
Tesla’s engineering has been the true driver of these cost efficiencies, and its focus on creating a vehicle that is as cost-effective to operate as possible is truly going to pay off as the vehicle begins to scale. Tesla wants to get the Cybercab to about 5.5-6 miles per kWh, which has been discussed with prototypes.
Additionally, fewer parts due to the umboxed manufacturing process, a lower initial cost, and eliminating the need to pay humans for their labor would also contribute to a cheaper operational cost overall. While aspirational, all of the ingredients for this to be a real goal are there.
It may take some time as Tesla needs to hammer the manufacturing processes, and Musk has said there will be growing pains early. This week, he said regarding the early production efforts:
“…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.”
