New Zealand startup Zenno Astronautics has completed the first orbital test of its "Supertorquer," a shoebox-sized superconducting magnet system that uses solar power and Earth's magnetic field to help control a satellite without fuel. The company says the technology could eventually support fuel-free satellite maneuvers, docking, deep-space trajectory changes, and even magnetic radiation shielding for astronauts. Space Magazine reports: The tests began shortly after Mira's launch in November last year aboard the SpaceX Transporter 12 mission and saw the shoebox-size device perform with flying colors, Zenno Astronautics CEO and founder Max Arshavsky, told Space.com. "It's a technology that allows a spacecraft to not tumble violently in space and point in the right direction," Arshavsky said. "The unit has multiple super-conducting magnets that are positioned in different axes. When we power up the magnets, they generate a magnetic field, which interacts with Earth's magnetic field, and because we can control the magnetic field on the satellite, we can control the way in which it turns with respect to Earth." Superconducting magnets are made of coils of superconducting wire that have zero electrical resistance and can therefore conduct much larger currents than normal wires. That larger current translates into a greater magnetic force. There is, however, a catch: Superconducting materials need to be cooled to extremely low temperatures to gain their wonder properties. [...] The unit housing the superconducting magnets is wrapped in layers of insulation and fitted with a heat pump that removes all the excess heat from the system. Every time the satellite needs a push, the superconducting coils power up, drawing energy from a battery charged by the satellite's solar panels. "It's converting solar energy straight into useful work," Arshavsky said. "Energy is the one thing that is abundant in space, and you can use it to energize the magnet to create a magnetic acceleration device. It gives you acceleration without fuel." In the future, Zenno Astronautics plans to launch larger systems that could enable spacecraft to dock in space or conduct close proximity operations using just the power of their solar-powered superconducting magnets. Arshavsky envisions powerful magnets that could, in the future, propel spacecraft on missions to the moon and Mars using only solar power.

Japan's Hayabusa2 probe captured rare close-up images of near-Earth asteroid Torifune, revealing a snowman-like shape made of two joined lobes. Phys.org reports: The fridge-sized Hayabusa2 skimmed asteroid Torifune on Sunday in a mission that demonstrated the ability to deflect a potentially dangerous space rock away from Earth. A new image released by the Japan Aerospace Exploration Agency (JAXA) on Monday could aid such efforts, as researchers say near-Earth asteroids vary in their size, shape and surface characteristics. "The moment I actually saw this image and the scientific data -- it really gave me goosebumps," JAXA scientist Yuya Mimasu told reporters, adding the asteroid "personally looked like a snowman." The black-and-white image, captured by a telescopic camera, showed what appeared to be two round objects joined together. "You can actually see the rocks... I really hadn't expected to be able to take a photo like this, so I'm absolutely over the moon," he said. [...] Moving at a speed of more than 18,000 kilometers (11,185 miles) per hour, the probe was due to fly within 800 meters (2,625 feet) of the asteroid, but JAXA said it would analyze the distance later. If confirmed, the mission would be one of the closest flybys of a near-Earth asteroid ever. JAXA also said Monday it succeeded in acquiring data from three other devices that can measure the distance from the asteroid and examine the existence of water.

An anonymous reader quotes a report from Wired: Meta launched its inaugural AI image model from the Meta Superintelligence Labs on Tuesday, its effort to compete with the likes of OpenAI's GPT Images 2.0 and Google's Nano Banana 2 in the AI image generation race. The new model, called Muse Image, rolled out with deep integrations woven into the Instagram app. As part of this update, public Instagram profiles are now automatically opted into being fodder for generative AI remixes. All someone has to do is tag your account's profile in a prompt -- if it's public -- and they can use Meta AI to generate an image using your likeness. Meta positions this feature as a cheeky way to personalize generations with images of real people. "Whether you want to design a custom event invitation, mock up a collaborative creative concept, or generate a personalized graphic, tagging a username lets Meta AI use public photos to build a visual that's ready to post," reads one of Meta's announcement blogs about the new AI tool. [...] Instagram's help center site includes more details about how this feature will impact users, saying that "people may be able to create content with your Instagram content using AI features at Meta" if you leave your account public and on the default settings. (A previously archived version of this page from 2025 does not include similar, AI-focused language.) Instagram users who want to stop others from using their public posts for AI images (without switching your account to private) must manually disable the options under the app's "Sharing and reuse" settings. However, turning off the setting only blocks future AI generations; any AI images already created from their content will remain. Meta also says users will not be notified when others create AI-generated content using their posts.
