The race to secure electricity for AI models has reached new heights: Meta has signed an agreement with the startup Overview Energy that could see a thousand satellites beam infrared light to solar farms that power data centers at night. In 2024, Meta's data centers used more than 18,000 gigawatt-hours of electricity ' roughly enough to power more than 1.7 million American homes for a year ' and its need for compute power is only increasing. The company has committed to building 30 gigawatts of renewable power sources, with a focus on industrial-scale solar power plants. Overview Energy, a four-year-old, Ashburn, Virginia, outfit that emerged from stealth in December, has a different solution: The company is developing spacecraft that collect plentiful solar power in space. It then plans to convert that energy to near-infrared light and beam it at sufficiently large solar farms ' on the order of hundreds of megawatts ' which can convert that light to electricity. By using a wide, infrared beam to power existing terrestrial solar infrastructure, Overview thinks it can sidestep the technological challenges and safety and regulatory issues that bedevil plans to transmit power to Earth through high-power lasers or microwave beams. CEO Marc Berte says you'll be able to stare right into his satellite's beam with no ill effects....

Jeff Bezos' space company Blue Origin successfully re-used one of its New Glenn rockets for the first time ever on Sunday, but the company failed at its primary mission: delivering a communications satellite to orbit for customer AST SpaceMobile. AST SpaceMobile issued a statement Sunday afternoon that the upper stage of the New Glenn rocket placed BlueBird 7 satellite into an orbit that was 'lower than planned.' The satellite successfully separated from the rocket and powered on, the company said, but the altitude is too low 'to sustain operations' and will now have to be de-orbited ' left to burn up in the atmosphere of Earth. The cost of the loss of the satellite is covered by AST SpaceMobile's insurance policy, according the company, and there are successive BlueBird satellites that will be completed in around a month. AST SpaceMobile has contracts with more than just Blue Origin, and the company said it expects to be able to launch 45 more to space by the end of 2026. But this represents the first major failure for Blue Origin's New Glenn program, which only made its first flight in January 2025 after more than a decade in development. This was the second mission where New Glenn carried a customer payload to space, after launching twin spacecraft bound for Mars on behalf of NASA last November. The company did not immediately respond to a request for comment....

Chances are, you've already used a satellite today. Satellites make it possible for us to stream our favorite shows, call and text a friend, check weather and navigation apps, and make an online purchase. Satellites also monitor the Earth's climate, the extent of agricultural crops, wildlife habitats, and impacts from natural disasters. As we've found more uses for them, satellites have exploded in number. Today, there are more than 10,000 satellites operating in low-Earth orbit. Another 5,000 decommissioned satellites drift through this region, along with over 100 million pieces of debris comprising everything from spent rocket stages to flecks of spacecraft paint. For MIT's Richard Linares, the rapid ballooning of satellites raises pressing questions: How can we safely manage traffic and growing congestion in space' And at what point will we reach orbital capacity, where adding more satellites is not sustainable, and may in fact compromise spacecraft and the services that we rely on' 'It is a judgement that society has to make, of what value do we derive from launching more satellites,' says Linares, who recently received tenure as an associate professor in MIT's Department of Aeronautics and Astronautics (AeroAstro). 'One of the things we try to do is approach these questions of traffic management and orbital capacity as engineering problems.'...

MIT Associate Professor Jacob Andreas of the Department of Electrical Engineering and Computer Science [EECS] and MIT Associate Professor Brett McGuire of the Department of Chemistry have been selected as the winners of the 2026 Harold E. Edgerton Faculty Achievement Award. Established in 1982 as a permanent tribute to Institute Professor Emeritus Harold E. Edgerton's great and enduring support for younger faculty members, this award is given annually in recognition of exceptional distinction in teaching, research, and service. 'The Department of Chemistry is extremely delighted to see Brett recognized for science that has changed how we think about carbon in space,' says Class of 1942 Professor of Chemistry and Department Head Matthew D. Shoulders. 'Brett's lab combines laboratory spectroscopy, radio astronomy, and sophisticated signal-analysis methods to pull definitive molecular fingerprints out of extraordinarily faint data. His discovery of polycyclic aromatic hydrocarbons in the cold interstellar medium has opened a powerful new window on astrochemistry. Moreover, Brett is inventing the creative and unique tools that make discoveries like this possible.'...
