Four astronauts from the U.S., France and Russia successfully arrived at the International Space Station via SpaceX rocket on Saturday, restoring full crew capacity.

Despite these successes, the highly technical nature of financial texts requires domain-specific LLMs to understand complex financial language and concepts effectively.

A key part of the SpaceX-xAI deal's rationale is to move datacentres - the central nervous system of AI tools - into space. A key part of the SpaceX-xAI deal's rationale is to move datacentres - the central nervous system of AI tools - into space. Why has Elon Musk merged his rocket company with his AI startup? SpaceX's acquisition of xAI creates business worth $1.25tn but whether premise behind deal will work is questioned The acquisition of xAI by SpaceX is a typical Elon Musk deal: big numbers backed by big ambition. As well as extending "the light of consciousness to the stars", as Musk described it, the transaction creates a business worth $1.25tn (£920bn) by combining Musk's rocket company with his artificial intelligence startup.

Most of the state may be fighting the invasive species by 2050. Breakthroughs, discoveries, and DIY tips sent six days a week. Termites have plagued southern states like Florida for decades, but a new study indicates that the problem is even worse than researchers previously believed. After reviewing over 30 years of monitoring data, entomologists at the University of Florida (UF) now say both the Formosan and Asian subterranean termites ( and) are expanding their range of destruction. They've already traveled farther north than scientists initially predicted.

Why did SpaceX just apply to launch 1 million satellites? We are only a month into 2026, yet it's already clear what one of the major space stories of the year is going to be: mega-constellations, and the ongoing attempts to launch thousands of satellites into Earth's orbit. The latest development is that SpaceX has asked the US Federal Communications Commission (FCC) for permission to launch 1 million orbital data centre satellites. The previous largest filing with the FCC, also by SpaceX, was for 42,000 Starlink satellites in 2019. "This is beyond what's been proposed by any constellation," says Victoria Samson at the Secure World Foundation in the US.

Each of these enormous collections of spacecraft, dubbed CTC-1 and CTC-2, would contain 96,714 satellites spread over 3,660 different orbits. If completed, China's new mega-constellation would dwarf even SpaceX's bold ambition to put 49,000 Starlink satellites in orbit. Together, CTC-1 and CTC-2 would be the largest assembly of satellites ever put in orbit, and would effectively lock competitors out of a region of low-Earth orbit. With Chinese authorities remaining quiet about the satellites' intended use, experts have raised concerns that the constellation may pose a security or defence threat. As reported by China in Space, the Nanjing University of Aeronautics claims that the satellites will focus on: 'Low-altitude electromagnetic space security, integrated security defence systems, electromagnetic space security assessment of airspace, and low-altitude airspace safety supervision services.'

NASA Artemis II plans to launch Feb. 6, 2025, sending astronauts Reid Wiseman, Victor Glover, Christina Koch and Jeremy Hansen on the first crewed lunar mission in 50 years.

Apple and Google have confirmed that Gemini's models power the new version of Siri and other generative AI features. Here's part of it: "Apple determined that Google's Al technology provides the most capable foundation for Apple Foundation Models Apple Intelligence will continue to run on Apple devices and Private Cloud Compute, while maintaining Apple's industry-leading privacy standards." In June, it was reported that Apple was considering partnerships with OpenAI and Anthropic for Siri (the voice assistant can currently tap ChatGPT for certain queries as part of Apple Intelligence). Two months later, Google emerged as a contender. Another report suggested Apple might build the new Siri using a custom version of Gemini -- and that it would pay Google around $1 billion a year for the privilege.

America's great journey in space is about to face its most consequential moment in half a century. Everyone agrees: It's a complete disaster. I. Artemis, We Have a Problem As you may have heard, NASA plans to send a crew of astronauts around the moon in early 2026, followed by a lunar landing in 2027. Or maybe you haven't heard. When I told one of my daughters about this plan to send people to the moon, she said, after a long silence: "But I thought we already sent a bunch of people there a long time ago." This is a standard response when I quiz people about Artemis, NASA's program to return to the moon, and this time to stay . It's named for Apollo's twin sister and the goddess of the moon and the hunt. The other day, I was in a gaggle with six neighbors, all highly informed professional people--two of them with long careers at the National Science Foundation--and none knew anything about Artemis except one thing: It's a plan to send people to Mars. Artemis is a moon mission. There is no Mars mission NASA has no Mars rocket, no Mars capsule, no Mars mission crew. What it does have is a very troubled moon program. Artemis faces fundamental engineering challenges that have called into question the program's basic architecture. Reconfiguring a mission this important is hard in the best of times, but the agency is being forced to do it during a year of unprecedented internal turmoil. A new administration always means turnover, but NASA has been in an uncontrolled spin every bit as alarming as the one Neil Armstrong famously pulled out of during in 1966. More than a year ago, President-elect Donald Trump nominated a billionaire entrepreneur and Elon Musk ally, Jared Isaacman, to become NASA administrator. It was an unconventional choice, but Isaacman drew support from many quarters in the space community. Then, right before Isaacman was poised for confirmation by the Senate, Trump and Musk had a nasty falling-out, and Trump yanked Isaacman's nomination. Since Inauguration Day, NASA had been run by acting administrator Janet Petro, a veteran agency official, and with Isaacman out, she remained in charge until one day in July when Trump suddenly named Secretary of Transportation Sean Duffy as interim administrator.

LLMs can be unpredictable, as even slight alterations to the prompt can cause the output to change in unexpected ways. Thus, the ability of models to accurately explain their behavior is critical, especially in high-stakes settings. One approach for evaluating explanations is counterfactual simulatability, how well an explanation allows users to infer the model's output on related counterfactuals. Counterfactual simulatability has been previously studied for yes/no question answering tasks. We provide a general framework for extending this method to generation tasks, using news summarization and medical suggestion as example use cases. We find that while LLM explanations do enable users to better predict LLM outputs on counterfactuals in the summarization setting, there is significant room for improvement for medical suggestion. Furthermore, our results suggest that the evaluation for counterfactual simulatability may be more appropriate for skill-based tasks as opposed to knowledge-based tasks.
