Relive SpaceX’s high-altitude Starship launch debut in 4K [video]
SpaceX has published a 4K recap of Starship serial number 8’s (SN8) spectacular high-altitude launch debut, highlighting all crucial aspects of the immensely successful test flight and hinting at the next steps forward.
On December 9th, after days of anticipation and delays for the unprecedented test flight, Starship SN8 sailed through a clean preflight flow, ignited three Raptor engines, and lifted off around 4:45 pm CST – just 15 minutes before the launch window was scheduled to close. In a move that would later be confirmed to be intentional, Starship’s ascent went exactly as planned with all three Raptors sequentially shutting down over the course of almost five minutes – necessary, said Elon Musk, to keep the rocket from “[blowing] through the [12.5-kilometer] altitude limit.”
Although technical difficulties prevented a high-altitude NASA reconnaissance jet from capturing aerial footage of the spectacle from up high, SpaceX certainly seems to have made do with more mundane platforms, capturing all aspects of Starship SN8’s launch in high definition.
At apogee, Starship SN8 vented most of the remaining liquid oxygen in its main tank and shut down the last active Raptor engine, kicking off an unprecedented guided freefall back to Earth. To achieve that feat, Starship SN8 had to reach apogee more or less vertical, begin falling tail-first, activate cold-gas thrusters and actuate four giant flaps to tilt belly-down, and use those same thrusters and flaps to maintain stability.
Likely reaching speeds of around 150 m/s (~330 mph) during that freefall, Starship SN8 made it look effortless, twitching its flaps and occasionally using a burst of thrusters to elegantly and stably glide back to about 1 km (~0.6 mi) above the ground. At that point, the rocket ignited one – and then two – Raptor engines with no apparent issue, gimballing violently and firing thrusters to flip its 9m by 50m (30 ft by 165 ft) hull ~120 degrees in a handful of seconds, ending in a tail-down landing configuration.
Up to that point, more than six minutes into the flight test, Starship SN8 had all but aced the gauntlet of firsts SpaceX had thrown at it, notably surpassing CEO Elon Musk’s expectation of a successful ascent but otherwise failed descent.
Instead, SN8 made it just a dozen or two seconds away from a soft landing before things went wrong. According to Musk, who commented after the fact, the Starship’s fuel (methane) header tank – a small secondary tank used to store landing propellant at high pressures – began to exhibit lower than needed pressures in the seconds before touchdown. Whether intentional or not, one of the two Raptors ignited during SN8’s flip maneuver shut down around ten seconds later, at which point the lone remaining engine throttled up only to have its plume turn an almost solid green.
In simple terms, without enough pressure in the fuel header, Raptor’s combustion turned very oxygen-rich, dramatically ramping up the heat and literally melting the engine’s copper-rich combustion chamber liner (hence the green hue). Had that tank been able to maintain pressure, it’s reasonable to assume that SN8 would have stuck a soft landing just like SN5 and SN6 did a few months prior. Thankfully, Musk says the source of the pressure issue was “minor” and, as SpaceX notes at the end of the recap, Starship SN9 is almost ready to carry the torch forward.
Tesla (NASDAQ: TSLA) showrooms have been picked clean ahead of the end of the third quarter of the year, as demand looks to be strong and delivery estimates for new vehicles are pushed into late 2026 and early 2027.
Tesla appears to have sold out of many of its Model 3 and Model Y trim levels in the United States, as only the Model Y RWD and Model Y All-Wheel-Drive are available for delivery before the end of the year.
Additionally, many showrooms are either completely empty or void of all but just one demo unit within the buildings themselves in an effort to bolster what could be one of Tesla’s best quarters in vehicle deliveries in recent memory.
I’m at Tesla right now and when I walked into their showroom I was shocked to see it basically empty.
I asked one of the people working there where all of the cars are “Gone – it’s the end of the quarter and we’ve sold out of everything… including the display vehicles”So… pic.twitter.com/rN7s3gE6sJ

All the cars are gone from Tesla Century City!
All they have is Model Y L, a self-driving video playing on the background. I guess the best product is no product. Either that or they just sold the showroom cars. pic.twitter.com/mzCjWaXwww

Show room is empty. I asked and they have sold the demo cars too. Delivery numbers better be outstanding! pic.twitter.com/jq5N28Q6tZ

Additionally, when I spoke to the guys at Tesla Mechanicsburg two weeks ago, when I returned the Model Y L, their third hauler of the week had just arrived, and every vehicle on it, along with every vehicle in their delivery lot, was accounted for and had a name attached to it for delivery.
Talking to the guys at the Mechanicsburg showroom on Friday, they couldn’t believe they had ANOTHER hauler coming in of cars for delivery—and each was accounted for
No car just sitting in inventory. They’re expecting a BIG quarter, and this is more than just the Y L https://t.co/ce801GkKVv

Tesla saw a 25 percent increase in deliveries in Q2 compared to the same quarter the year before. The vast majority of the 480,126 units it delivered, 467,762 vehicles to be exact, were the Model 3 and Model Y.
In Q3 2025, Tesla delivered 497,099 vehicles, once again a figure that was dominated by the company’s two mass-market vehicles. Analysts have unusually wide predictions for this quarter, likely because so many firms missed the Q2 delivery figure by such a substantial margin; Wall Street predicted 408,000 cars, while Tesla delivered 480,000.
Goldman Sachs has Tesla slotted for 435,000 deliveries in Q3, while JPMorgan said it anticipates 482,000. The median guess is about 449,000 deliveries for Q3.

Tesla’s Automatic Collision Evasion feature can be seen in one of the first owner videos of it in action.
Tesla owner Spencer (@scotsrule08) posted on Monday that the feature “worked flawlessly,” saying FSD reengaged itself just as he was about to hit a curb. Ashok Elluswamy, who leads Tesla’s AI team, shared the clip and wrote, “A guardian angel always looking out for you.”
The video arrives in the middle of a staged rollout. Tesla first shipped Automatic Collision Evasion with FSD (Supervised) v14.3.9 in software update 2026.27.6 earlier this month, which Teslarati covered as it reached cars. Update 2026.27.10, which began going out on September 19, carried the feature improvements with FSD v14.3.10, according to release notes tracked by Not a Tesla App. The newer 2026.27.11 build is now reaching another wave of vehicles.

The feature only runs on HW4 vehicles, and it requires an active FSD purchase or subscription with both FSD (Supervised) and Automatic Emergency Braking enabled. HW3 owners receive FSD v14.2 Lite in the same updates, but that build does not include collision evasion.
Tesla’s release notes describe two triggers. The first is an imminent frontal collision that braking alone may not prevent, in which case the car can activate FSD to steer, brake or accelerate around the hazard. That scenario is limited to highways below 85 mph, with no pedestrians or cyclists detected and no slippery road surface. The second covers a driver who appears inattentive, such as reaching into the back seat, or who seems to have switched off FSD by accident. Spencer’s curb clip appears to fall into that second category.
Tesla plans big safety improvements for Full Self-Driving v15
Once the system takes over, the accelerator is muted and light brake input will not cancel the maneuver. Drivers need to apply firm, deliberate steering force to take back control, and the car chimes to hand control back once the danger has passed.
Elluswamy recently noted that earlier hazard prediction, faster reaction time and better collision avoidance would arrive with FSD v15, the next major version.
Tesla is delaying its event for the Roadster, moving it from this Thursday, October 1, to Thursday, October 15, due to unfavorable weather.
The company has said it has been tracking the weather for this Thursday closely with local meteorologists, and because the event can only be held outside, Tesla is making the call to delay it:
“We’ve been tracking the weather closely with local meteorologists, but given the severe conditions predicted & because this event can only be held outdoors, we’ve made the difficult decision to reschedule. New date is October 15. Additional details to follow.”

We are sure that this is bringing back PTSD for some Tesla fans, and we know it is not ideal, but this also reveals some things about the event. Tesla said that this can only be held outdoors, meaning it bodes well for the rumors that the vehicle could potentially hover.
Some believe that this was essentially confirmed by the FAA airspace restriction they were granted, but this could have been for a drone show or to keep drones from spying on the event.
Tesla Roadster is available for order once again following brief hold
The Roadster event has been long-awaited, and it is unfortunate that the weather is going to keep us all waiting a little bit longer.
The Tesla Roadster will be unveiled in Waco, Texas.
