After launching just once in the last ten weeks, SpaceX appears to be set to return to H1 2021 stride and has scheduled the launches of a historic all-private Crew Dragon mission and the first batch of laser-linked Starlink ‘V1.5’ satellites less than 48 hours apart.

First up, SpaceX is on track for its first dedicated Starlink launch in almost four months (~16 weeks) – this time carrying upgraded V1.5 spacecraft – as early as 8:55 pm PDT, Monday, September 13th (03:55 UTC 14 Sept). Aside from quite possibly marking the last time ever that SpaceX goes 3+ months without a Starlink launch, the “Starlink 2-1” mission will be the company’s first West Coast launch in ten months and first West Coast Starlink launch ever.

As few as ~44 hours later, SpaceX is now fully ready to launch both Dragon’s and the world’s first crew of all-private astronauts into the highest orbit reached by humans since 2009 no earlier than 8:05 pm EDT, Wednesday, September 15th (00:05 UTC 16 Sept). Known as Inspiration4, there is a real chance that the mission could mark a turning point for the future of true orbital space tourism and will be the first of at least four or five private Crew Dragon launches scheduled in the next few years.

Both missions will mark important technical milestones in their own right. As previously discussed on Teslarati, Inspiration4 will launch on a twice-flown Falcon 9 booster and with a Dragon space capsule that was in orbit less than five months prior, setting new records for crewed booster reuse and orbital space capsule turnaround. Its all-private four astronaut crew (also a first in spaceflight history) will reach altitudes as high as 575 km (357 mi) – the highest humans have traveled since 2009 and the seventh-highest crewed Earth orbit spaceflight of all time.

On the opposite side of the United States, SpaceX is also gearing up for the dedicated launch of a batch of 51 ‘Starlink V1.5’ satellites. Known as Starlink 2-1 or Starlink Group 2-1, the mission will mark the start of a new ‘shell’ of SpaceX’s low Earth orbit (LEO) Starlink constellation, the first dedicated Starlink launch since May 26th, the first dedicated Starlink launch with laser-linked spacecraft, and SpaceX’s first West Coast launch since November 2020. Additionally, Starlink 2-1 will launch on a nine-flight Falcon 9 booster – the second time a SpaceX rocket has completed ten orbital-class launches and landings if all goes to plan.

Originally scheduled to launch as early as July, SpaceX is believed to have delayed Starlink 2-1 until the design and production of upgraded V1.5 satellites were ready to support the 51-satellite launch. Until SpaceX or its CEO provide more information, all that’s known about the new V1.5 design is that its main focus was the addition of inter-satellite optical links (laser links). Those ‘space lasers’ are designed to allow Starlink satellites to route communications themselves, enabling potentially unbeatable latency, internet coverage over oceans and extremely sparse regions, and a network that doesn’t need line-of-sight ground stations to function.

Technically, SpaceX has already launched 13 Starlink satellites with laser links and has been testing those spacecraft for the last 2-9 months, hopefully meaning that the V1.5 satellites SpaceX launches later today will be more reliable than their first-of-their-kind Starlink V0.9 and V1.0 cousins.

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.
