For the second time ever, a SpaceX Falcon 9 booster is set to launch for the fifth time, supporting the company’s sixth Starlink satellite launch this year and offering a second opportunity to secure a big rocket reusability record.

Somehow less than three months ago, Falcon 9 booster B1048 lifted off for the fifth time, becoming the first SpaceX rocket to do so since the company began reusing boosters in March 2017 and debuted Falcon 9’s 10-flight Block 5 upgrade in May 2018. Two years after Block 5’s debut, SpaceX has built 14 of the boosters – four for Falcon Heavy – and they’ve successfully completed 31 launches and 29 landings. Unfortunately, although B1048’s fifth launch was technically a success, the booster suffered SpaceX’s first in-flight engine failure in ~8 years.

SpaceX’s Starlink-8 launch will be streamed live starting around 9:05 pm EDT (01:05 UTC).

While B1048 was able to account for that engine shutdown on the fly, expending extra propellant meant for its reentry and landing burns to ensure that its payload of 60 Starlink satellites could still reach orbit, that correction removed the possibility of a successful landing. As a result, SpaceX has technically launched a booster five times but it has yet to launch and land a booster five times.

Now scheduled to launch no earlier than 9:25 pm EDT, June 3rd (01:25 UTC, June 4), SpaceX’s eight 60-satellite Starlink mission will see Falcon 9 B1049 become the second booster to launch five times, providing another opportunity to set the record for orbital-class booster landings.

If successful, B1049’s fifth launch and landing will set the booster up to become the first SpaceX rocket to fly six times (and hopefully seven or more beyond that), making it the company’s fleet leader after B1048’s failed March 2020 landing attempt destroyed the booster before it could be crowned. Impressively, according to comments recently made by SpaceX COO and President Gwynne Shotwell, the condition of Falcon 9 Block 5 boosters after multiple orbital-class launches and landings is so encouraging that she believes each booster should be able to fly more than 10 times each.

The first double-digit booster could come much sooner than later thanks to SpaceX’s ambitious Starlink launch schedule and the small fleet of rockets it’s likely to have for the rest of the year. In June alone, SpaceX has three Starlink launches and its second US military GPS III satellite mission planned, one of which will likely see Falcon 9 B1051 become the third booster to complete five launches. With as many as 18 additional launches scheduled in the next seven months, B1049 or B1051 could easily be up to 7, 8, 9, or even 10 flights by the end of 2020.

Regardless, tune in around 9:05 pm EDT (01:05 UTC) to watch SpaceX’s 8th Starlink launch live.

Nvidia CEO Jensen Huang explains difference between Tesla FSD and Alpamayo

“Tesla’s FSD stack is completely world-class,” the Nvidia CEO said.

NVIDIA CEO Jensen Huang has offered high praise for Tesla’s Full Self-Driving (FSD) system during a Q&A at CES 2026, calling it “world-class” and “state-of-the-art” in design, training, and performance. 

More importantly, he also shared some insights about the key differences between FSD and Nvidia’s recently announced Alpamayo system. 

Jensen Huang’s praise for Tesla FSD

Nvidia made headlines at CES following its announcement of Alpamayo, which uses artificial intelligence to accelerate the development of autonomous driving solutions. Due to its focus on AI, many started speculating that Alpamayo would be a direct rival to FSD. This was somewhat addressed by Elon Musk, who predicted that “they will find that it’s easy to get to 99% and then super hard to solve the long tail of the distribution.”

During his Q&A, Nvidia CEO Jensen Huang was asked about the difference between FSD and Alpamayo. His response was extensive:

“Tesla’s FSD stack is completely world-class. They’ve been working on it for quite some time. It’s world-class not only in the number of miles it’s accumulated, but in the way it’s designed, the way they do training, data collection, curation, synthetic data generation, and all of their simulation technologies.

“Of course, the latest generation is end-to-end Full Self-Driving—meaning it’s one large model trained end to end. And so… Elon’s AD system is, in every way, 100% state-of-the-art. I’m really quite impressed by the technology. I have it, and I drive it in our house, and it works incredibly well,” the Nvidia CEO said. 

Nvidia’s platform approach vs Tesla’s integration

Huang also stated that Nvidia’s Alpamayo system was built around a fundamentally different philosophy from Tesla’s. Rather than developing self-driving cars itself, Nvidia supplies the full autonomous technology stack for other companies to use.

“Nvidia doesn’t build self-driving cars. We build the full stack so others can,” Huang said, explaining that Nvidia provides separate systems for training, simulation, and in-vehicle computing, all supported by shared software.

He added that customers can adopt as much or as little of the platform as they need, noting that Nvidia works across the industry, including with Tesla on training systems and companies like Waymo, XPeng, and Nuro on vehicle computing.

“So our system is really quite pervasive because we’re a technology platform provider. That’s the primary difference. There’s no question in our mind that, of the billion cars on the road today, in another 10 years’ time, hundreds of millions of them will have great autonomous capability. This is likely one of the largest, fastest-growing technology industries over the next decade.”

He also emphasized Nvidia’s open approach, saying the company open-sources its models and helps partners train their own systems. “We’re not a self-driving car company. We’re enabling the autonomous industry,” Huang said.
