NASA astronauts will venture outside the International Space Station on Tuesday, June 30, to replace a wrist joint on the orbital complex’s Canadarm2 robotic arm. The spacewalk is scheduled to begin at approximately 8:35 a.m. EDT.
Experts from NASA and CSA (Canadian Space Agency) will preview the upcoming spacewalk during a news conference at 2 p.m. on Thursday, June 25, on the agency’s YouTube channel. The briefing will take place at NASA’s Johnson Space Center in Houston. Learn how to watch NASA content through a variety of platforms, including social media.
Starfall is SpaceX’s mass-produced reentry vehicle designed to autonomously transport valuable customer experiments and other payloads safely back from space to Earth, including for in-orbit manufacturing. Starfall is a cylindrical-shaped capsule approximately 0.75 meters tall with a diameter of 3.1 meters, weighing approximately 2,100 kilograms, and capable of carrying 1,000 kilograms of payload. It is designed to be carried on Starship flights.

What neuroscience reveals about how intelligence actually works — and how those insights are informing the next generation of AI architectures.

MIRA, an autonomous AI agent tested in a sandboxed electronic health record, diagnosed 574 real emergency department cases with 88.9% accuracy and outperformed physicians in a matched 311-case comparison. The system ordered tests, generated medication plans, and made admission decisions in simulation, but the authors stress that prospective validation, governance, and physician oversight are still essential.
That was Tracy R. Atkins’ message when I sat down with him 14 years ago, and it lands harder now than it did then.
While almost every story about #ArtificialIntelligence was busy imagining the apocalypse, Tracy wrote a novel that flatly refused to. Aeternum Ray is unapologetically utopian: a series of letters from a 240-year-old father to his newborn son, looking back across centuries of love, loss, and a world watched over by an AI named Ray.
In our conversation, we get into what the #Singularity actually means to him, why he chose to write utopia when dystopia sells, whether humanity’s future is digital or whether biology still matters, and the uncomfortable question of whether we even survive the road to get there.
Fourteen years on, the technology has caught up to much of what we talked about. The harder question is whether our reasons for building it have, and that is the part I keep coming back to.
So is openly imagining a good future naive, or is it the most radical thing a #futurist can do? Watch the interview and decide for yourself.

SpaceX may have just dropped its biggest hint yet about what comes after Starship Flight 13. Indeed, FINALLY! Starship’s Next Giant Leap may be here as the new filings point toward an Orbital Return Demo that could mark the next major milestone on the road to full reusability. With that work continues at Starbase on Pads 1 and 2, the Gigabay, and future launch infrastructure. Elsewhere this week, we cover Falcon 9 launches carrying BlueBird satellites, Starlink, and another classified NRO mission, Cargo Dragon’s return from the International Space Station, Astrobotic’s Griffin lunar lander preparing for launch, Ariane 6’s impressive upgraded debut with its heaviest payload yet, and the dramatic demolition of historic structures at Space Launch Complex 6.
The first human clinical trial of a universal Sarbeco coronavirus vaccine, developed by the University of Cambridge and spin-out DIOSynVax (DVX) Ltd, has shown that the vaccine is safe and has no significant side effects.
The trial, involving 39 healthy volunteers, tested a vaccine designed to provide protection against multiple Sarbeco coronaviruses—the large group of viruses that occur in nature including SARS-CoV-2, which caused the COVID pandemic.
The vaccine triggered immune responses in the volunteers not only to SARS-CoV-2 and SARS, but to related bat viruses that could potentially jump from animals to humans and cause future pandemics.
What if memory isn’t storage at all — but a message from your past self that has to be interpreted?
In this episode, biologist Michael Levin and cognitive neuroscientist Katrina Schleisman join me to take apart one of the most quietly broken ideas in science and AI: that memory works like a hard drive. It doesn’t. And once you see why, a lot of assumptions about minds, machines, and what it means to \.
For the first time, new algorithms may be able to automatically explain why some self-driving cars crash—a question crucial to answer as more autonomous vehicles take to the roads. This new approach, developed by researchers at King’s College London, reviews past events to explain why specific instances of failure happened, in the hope that this can be used to make improvements in the future.
The research was presented at the 2026 IEEE International Conference of Robotics and Automation.
Self-driving vehicles are increasingly being rolled out across the globe, in cities like London and San Francisco, but collisions and serious breaches of road safety have put pressure on manufacturers to explain why they make the mistakes they do. This is often hard to do, and current methods only provide limited explanations for these.
