Axiom-2 consists of 4 astronauts, Commander Peggy Whitson, a retired NASA Astronaut and now Director of Human Space Flight for Axiom Space, has spent 665 days in space, including numerous spacewalks while living aboard the International Space Station. The designated pilot for this mission is John Shofner, an American race car driver and pilot, who paid for his seat.
There are two Mission Specialists flying as well. First is Rayyanah Barnawi, who holds a bachelor’s degree in biomedical research and is the first Saudi female Astronaut. Flying alongside her is Ali AlQarni, who also holds a bachelor’s in aeronautical sciences and is a Captain in Royal Saudi Air Force. The Saudi Space Commission paid for both seats.

It is estimated that the cost for each seat is roughly $55 million, this includes the ride to space, food, and using the facilities aboard the International Space Station.
The 4 crew members will spend 8 days aboard the orbiting outpost conducting numerous experiments and media outreach. Originally the mission was to be ten days, but due to the scheduling of supply missions to the International Space Station, the mission was shortened to 8 days. The crew is expected to arrive at the International Space Station roughly 16 hours after launch from Kennedy Space Center, where they will be greeted by the 7 current astronauts and cosmonauts living aboard the ISS.
This launch also was the first time a Falcon 9 performed a Return to Launch Site (RTLS) for a Crewed mission. Thanks to their numerous Starlink launches, SpaceX has been able to show the Falcon 9 has the capabilities to complete the RTLS safely, which will also help with a quicker turnaround time for the boosters used on Crew and Resupply missions to the ISS.

The first stage that completed this flight is a rookie amongst the Falcon 9 fleet, B1080, completing its first flight. It may have showed a few nerves at first, with a small leak in its attitude control system that is used during the landing sequence of its flight. However, the leak proved to not be an issue, as B1080 performed a perfect landing at LZ-1 at Cape Canaveral Air Force Station.
Following their stay aboard the ISS, the Crew disembark and make a fiery plunge through the atmosphere with a parachute-assisted landing off of the Florida coast.

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.

Elon Musk confirms xAI’s purchase of five 380 MW natural gas turbines
The deal, which was confirmed by Musk on X, highlights xAI’s effort to aggressively scale its operations.
xAI, Elon Musk’s artificial intelligence startup, has purchased five additional 380 MW natural gas turbines from South Korea’s Doosan Enerbility to power its growing supercomputer clusters.
The deal, which was confirmed by Musk on X, highlights xAI’s effort to aggressively scale its operations.
xAI’s turbine deal details
News of xAI’s new turbines was shared on social media platform X, with user @SemiAnalysis_ stating that the turbines were produced by South Korea’s Doosan Enerbility. As noted in an Asian Business Daily report, Doosan Enerbility announced last October that it signed a contract to supply two 380 MW gas turbines for a major U.S. tech company. Doosan later noted in December that it secured an order for three more 380 MW gas turbines.
As per the X user, the gas turbines would power an additional 600,000+ GB200 NVL72 equivalent size cluster. This should make xAI’s facilities among the largest in the world. In a reply, Elon Musk confirmed that xAI did purchase the turbines. “True,” Musk wrote in a post on X.
xAI’s ambitions
Recent reports have indicated that xAI closed an upsized $20 billion Series E funding round, exceeding the initial $15 billion target to fuel rapid infrastructure scaling and AI product development. The funding, as per the AI startup, “will accelerate our world-leading infrastructure buildout, enable the rapid development and deployment of transformative AI products.”
The company also teased the rollout of its upcoming frontier AI model. “Looking ahead, Grok 5 is currently in training, and we are focused on launching innovative new consumer and enterprise products that harness the power of Grok, Colossus, and 𝕏 to transform how we live, work, and play,” xAI wrote in a post on its website.
