NASA says “nothing has changed” as US astronaut prepares to ride Russian spacecraft
An official Russian video posted on Twitter has fueled rampant speculation that the country’s beleaguered space agency intends to abandon NASA astronaut Mark Vande Hei on the International Space Station.
On March 5th, a Russian state news outlet “RIA Novosti” shared a video on Twitter that depicted Mark Vande Hei being left on the Internation Space Station, rather than departing on board the Russian Soyuz spacecraft as planned. The video was just the latest example of growing tension between Russia and the rest of the world as sanctions for the illegal invasion of Ukraine and some of the country’s own responses to those sanctions have rapidly severed many of its ties to the international space industry. So far, Russia has terminated commercial Soyuz launch operations at the European Space Agency’s launch site in Kourou, French Guiana, effectively stolen several rockets already purchased by satellite internet company OneWeb, and cut-off sales and support for Russian rocket engines used in two US rockets.
As a result, the future of the International Space Station (ISS) has never felt less certain. In recent days, these concerns have grown exponentially as many news outlets began to report on purported concerns that Vande Hei would be abandoned on the ISS.
Dmitry Rogozin, the director-general of the Russian federal space agency Roscosmos, has also been posting a number of increasingly chaotic tweets claiming that Western sanctions will “destroy their International Space Station partnership” and making threats about potential catastrophes that could unfold on the ISS without Russian contributions.
Despite these claims, NASA has reassured the public that “operations have not changed at all”.
Vande Hei is scheduled to depart from the ISS later this month aboard a Russian Soyuz spacecraft with cosmonauts Anton Shkaplerov and Petr Dubrov, ultimately touching down in Kazakhstan. However, even if Russia were to decide to leave Van Hei aboard the space station, he would not be “stranded”. Three American astronauts – Raja Chari, Kayla Barron, and Thomas Marshburn remain aboard the ISS along with German ESA astronaut Matthias Maurer. Additionally, thanks entirely to SpaceX, NASA has its own domestic transportation to and from the ISS in the form of Crew Dragon. In theory, it’s possible that NASA’s current ISS crew could somehow modify Crew Dragon to return five – not four – astronauts to Earth, allowing Vande Hei to extract himself from a tense political conundrum.
However, that may not be possible in such a short time frame, as SpaceX would need to find a way to add a fifth seat to Dragon and figure out how to accommodate Vande Hei’s Russian spacesuit. That work could easily take weeks or months to safely complete, potentially forcing Mark to stay in space for at least another half a year to return to Earth with Crew-4 instead of Crew-3. Even then, Crew-4 is scheduled to launch just one month from now, so even that alternative may not be a viable.
Regardless, given the unprovoked, irrational, and increasingly brutal nature of Russia’s second invasion of Ukraine, Russia’s international spaceflight partnerships have never been more unstable. While unlikely, it’s possible that Rogozin or Putin himself could choose to end the ISS partnership altogether, though there is a great deal of ambiguity as to whether either ISS ‘segment’ could survive on its own. Thankfully, NASA has partial alternatives to some of the services the Russian ISS segment has provided. Northrup Grumman’s Cygnus spacecraft intends to perform the first Western ISS reboost maneuver later this year. Russia has been almost exclusively responsible for ISS reboosting and maneuvering over the two-decade life of the station.
Meanwhile, in spite of the circumstances, Vande Hei is still on track to break the American record for the longest continuous stay in space, beating out NASA astronaut Scott Kelly’s 340-day streak by about two weeks. NASA associate space operations administrator Kathy Lueders stated in a press conference that NASA “[is] getting ready for Mark to return, and all of the normal operations are in place for that for us to be able to do that”.
Once on the ground in Kazakhstan, Vande Hei will be met by a team of NASA personnel tasked with bringing the astronaut back to Houston, Texas. He will then start the recovery process after living in microgravity for almost a full year.

Tesla Model Y leads South Korea’s EV growth in 2025
Data from the Korea Automobile and Mobility Industry Association showed that the Tesla Model Y emerged as one of the segment’s single biggest growth drivers.
South Korea’s electric vehicle market saw a notable rise in 2025, with registrations rising more than 50% and EV penetration surpassing 10% for the first time.
Data from the Korea Automobile and Mobility Industry Association showed that the Tesla Model Y, which is imported from Gigafactory Shanghai, emerged as one of the segment’s single biggest growth drivers, as noted in a report from IT Home News.
As per the Korea Automobile and Mobility Industry Association’s (KAMA) 2025 Korea Domestic Electric Vehicle Market Settlement report, South Korea registered 220,177 new electric vehicles in 2025, a 50.1% year-over-year increase. EV penetration also reached 13.1% in the country, entering double digits for the first time.
The Tesla Model Y played a central role in the market’s growth. The Model Y alone sold 50,397 units during the year, capturing 26.6% of South Korea’s pure electric passenger vehicle market. Sales of the Giga Shanghai-built Model Y increased 169.2% compared with 2024, driven largely by strong demand for the all-electric crossover’s revamped version.
Manufacturer performance reflected a tightly contested market. Kia led with 60,609 EV sales, followed closely by Tesla at 59,893 units and Hyundai at 55,461 units. Together, the three brands accounted for nearly 80% of the country’s total EV sales, forming what KAMA described as a three-way competitive market.
Imported EVs gained ground in South Korea in 2025, reaching a market share of 42.8%, while the share of domestically produced EVs declined from 75% in 2022 to 57.2% last year. Sales of China-made EVs more than doubled year over year to 74,728 units, supported in no small part by Tesla and its Model Y.
Elon Musk, for his part, has praised South Korean customers and their embrace of the electric vehicler maker. In a reply on X to a user who noted that South Koreans are fond of FSD, Musk stated that, “Koreans are often a step ahead in appreciating new technology.”

Samsung’s Tesla AI5/AI6 chip factory to start key equipment tests in March: report
Samsung Electronics seems to be ramping its efforts to start operations at its Taylor, Texas semiconductor plant.
Samsung Electronics seems to be ramping its efforts to start operations at its Taylor, Texas semiconductor plant, which will produce Tesla’s next-generation AI5 chip.
Preparing for Tesla’s AI5/AI6 chips
As per a report by Sina Finance, Samsung Electronics is looking to begin trial operations of extreme ultraviolet (EUV) lithography equipment at its Taylor facility in March. These efforts are reportedly intended to support the full production of Tesla’s AI5 chips starting in the latter half of 2026.
The Taylor factory, Samsung’s first wafer fabrication plant in the United States, covers roughly 4.85 million square meters and is nearing completion. Media reports, citing contractors, have estimated that about 7,000 workers now work on the factory, about 1,000 of whom are reportedly working from the facility’s office building.
Samsung is reportedly preparing to apply for a temporary occupancy permit, which would allow production to begin before the plant is fully completed.
Tesla’s aggressive AI chip roadmap
Elon Musk recently stated that Tesla’s next-generation AI5 chip is nearly complete, while early development on its successor, AI6, is already underway. Musk shared the update in a post on X, which also happened to be a recruiting message for engineers.
As per Musk, Tesla is looking to iterate its in-house AI chips on an accelerated timeline, with future generations, including AI7, AI8, and AI9, targeting a roughly nine-month design cycle. He also stated that the rapid cadence could allow Tesla’s chips to become the highest-volume AI processors in the world.
Previous reports have indicated that Samsung Electronics would be manufacturing Tesla’s AI5 chip, alongside its rival, Taiwan Semiconductor Manufacturing Company (TSMC). The two suppliers are expected to produce different versions of Tesla’s AI5 chip, with TSMC using a 3nm process and Samsung targeting 2nm production.

Elon Musk’s Boring Company studying potential Giga Nevada tunnel: report
The early-stage feasibility work was funded by a state-affiliated economic group as officials searched for alternatives to worsening traffic and accidents along Interstate 80.
Elon Musk’s tunneling startup, The Boring Company, has been studying a potential tunnel system connecting Reno to Tesla Gigafactory Nevada, as per documents obtained by Fortune. The early-stage feasibility work was funded by a state-affiliated economic group as officials searched for alternatives to worsening traffic and accidents along Interstate 80.
Potential Giga Nevada tunnel
Documents reviewed by Fortune showed that The Boring Company received $50,000 in October to produce conceptual designs and a feasibility report for a tunnel beneath a nine-mile stretch of highway leading to Gigafactory Nevada. The payment came from the Economic Development Authority of Western Nevada (EDAWN), a nonprofit that works with the state to attract and expand businesses.
The proposed tunnel was one of several transportation alternatives being explored to address rising congestion and accidents along Interstate 80, which serves the Tahoe-Reno Industrial Center. The massive industrial park houses major employers, including Tesla and Panasonic, both of which had been in contact with the Nevada Governor’s Office regarding potential transportation solutions.
Emails obtained through public records requests showed that Tesla and Panasonic have also supported a separate commuter rail study that would use existing freight rail alongside the Interstate. It remains unclear if The Boring Company’s feasibility report had been completed, and key details for the potential project, including tunnel length, cost, and if autonomous Teslas would be used, were not disclosed.
Relieving I-80 congestion
Traffic and accidents along I-80 have increased sharply as data centers and new businesses moved into the 107,000-acre industrial center. State transportation data showed that the number of vehicles traveling certain stretches of the highway during peak hours doubled between January and July 2025 alone. Roughly 22,000 employees commute daily to the industrial park, with nearly 8,000 working for Tesla and more than 4,000 for Panasonic at the Giga Nevada complex.
Bill Thomas, who runs the Regional Transportation Commission of Washoe County, shared his thoughts about safety concerns in the area. “At this point in time, there’s about (one accident) every other day,” he said. He also noted that he is supportive of any projects that could alleviate traffic and accidents on the Interstate.
“We’re not paying for it. I’m not involved in it. But I understand there are conversations exploring whether that could be done. If there’s a private solution that helps the problem and improves safety, as far as I’m concerned, more power to them,” Thomas stated.
