In sending a car-sized rotorcraft to explore Saturn’s moon Titan, NASA’s Dragonfly mission will undertake an unprecedented voyage of scientific discovery. And the work to ensure that this first-of-its-kind project can fulfill its ambitious exploration vision is underway in some of the nation’s most advanced space simulation and testing laboratories. Set for launch in in 2028, the Dragonfly rotorcraft is being designed and built at the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland, with contributions from organizations around the world. On arrival in 2034, Dragonfly will exploit Titan’s dense atmosphere and low gravity to fly to dozens of…

Tinfoil Hats Beware A lot of people have mixed feelings about current FCC Chairman Brendan Carr but the recent decision “to create a new category of unlicensed devices… that can operate outdoors and at higher power than previously authorized devices.”  These ‘Geofenced variable power’ devices will operate in the 6 GHz band and provide up to 11 dBm/MHz power spectral density and 24 dBm effective isotropic radiated power.  This is a bump up from the current 5 dBm/MHz limit for VLP devices in the USA. This would enable VLP WiFi to provide enough signal strength to handle AR/VR devices and…

Every third booth at CES showed off some new AI product or other. If you wanted to find a robotic lawn mower, throw a rock. Humanoid robots, smart locks and super thin TVs were everywhere. But if you went looking for sustainability products, you’re going to have to hunt a bit.Last year, the Sustainability section at the Las Vegas Convention Center had 20 booths. This year, there were 38, but that’s in part due to the combination of the energy and sustainability categories. So exhibitors like South Korea’s largest electric utility company, a nuclear power company from the same country…

Olivas is very credible on these issues. He was asked by the NASA leadership in late 2023, before the independent review team was formally named, to provide a second set of eyes on the space agency’s heat shield work. He saw all of the investigative data in real time. Although not formally a member, he sat in on the review team’s meetings through 2024 before that process ended. Afterward, he had some lingering questions he felt were unresolved by that process. A few weeks ago, he told Pearlman and me he would be reluctant to fly on Orion. It was…

Valve is supposed to reveal pre-order options for the Steam Machine in early 2026 but PC gaming prices are getting out of control. Ubisoft is already hyping up The Division 3. And a mystery game is set to appear at the first Xbox showcase of 2026. Pentiment 2? It’s another edition of Morning Checkpoint, Kotaku‘s daily roundup of gaming news and culture. While it’s been the case for years now that physical games come with almost nothing inside the case but the disc, I still feel a brutal pang of disappointment every time I encounter it. I recently bought a…

As booster manager for NASA’s SLS (Space Launch System), Dave Reynolds’ path to NASA is embodied by his childhood poster of the space shuttle’s Return to Flight initiative, which hangs in his office, serving as a constant reminder that his journey to the agency began decades ago. Growing up in Roy, Utah, Reynolds remembers standing outside to watch the billowing smoke rise from booster tests at Northrop Grumman’s Promontory facility. Rockets were the backdrop of his childhood, and growing up during the shuttle missions sparked his fascination for space exploration. As the booster manager for the SLS, Dave is responsible…

International launches… China, which attempted 92 orbital launches in 2025, is second, followed by Russia, with 17 launches last year, and Europe with eight. Rounding out the 2025 orbital launch manifest were five orbital launch attempts from India, four from Japan, two from South Korea, and one each from Israel, Iran, and Australia, the analysis shows. The global launch tally has been on an upward trend since 2019, but the numbers may plateau this year. SpaceX expects to launch about the same number of Falcon 9 rockets this year as it did last year as the company prepares to ramp…

Recently, the topic of 2010’s Fallout: New Vegas and Bethesda creative director Todd Howard came up during a New Year’s Eve party I attended. During the conversation, a few people, myself included, joked about how Howard doesn’t like New Vegas, a Fallout game developed not by Bethesda but by Obsidian. Look around online, and you’ll see plenty of others joking and suggesting the same thing. Howard hates New Vegas. Or is at least annoyed by its success. Here’s the thing: There’s no evidence this is true, and in fact, Bethesda’s famed creative director has stated multiple times publicly that he…

Early, ancestral members of the human lineage may have left Africa earlier than widely thought, a new study of fossil teeth suggests.Modern humans, Homo sapiens, are the only living member of the human lineage, Homo, which is thought to have arisen in Africa about 2 million to 3 million years ago and first left that continent a few hundred thousand years ago. But many other extinct human species previously roamed Earth, such as Homo habilis, suspected to be among the first stone-tool makers, and Homo erectus, the first to regularly keep the tools it made.Scientists investigated fossils excavated from the…
