“International partners, I have not been allowed to talk to yet because of the trade wars.” Gen. Michael Guetlein, the senior officer in charge of the US military’s planned Golden Dome missile defense shield, has laid out an audacious schedule for deploying a network of space-based sensors and interceptors…
These chemical oddities may explain why Earth seems to be deficient in certain elements. For close to a century, geoscientists have pondered a mystery: Where did Earth’s lighter elements go? Compared to amounts in the Sun and in some meteorites, Earth has less hydrogen, carbon, nitrogen, and sulfur, as…

“These are just the difficulties of designing a spacesuit for the lunar environment.” Crew members traveling to the lunar surface on NASA’s Artemis missions should be gearing up for a grind. They will wear heavier spacesuits than those worn by the Apollo astronauts, and NASA will ask them to…
Rice University chemists replicated Thomas Edison’s seminal experiment and found a surprising byproduct. Graphene is the thinnest material yet known, composed of a single layer of carbon atoms arranged in a hexagonal lattice. That structure gives it many unusual properties that hold great promise for real-world applications: batteries, super…
Another partially reusable Chinese rocket, the Long March 12B, is nearing its first test flight. Welcome to Edition 8.26 of the Rocket Report! The past week has been one of advancements and setbacks in the rocket business. NASA rolled the massive rocket for the Artemis II mission to its…

The Swarm Garden: An array of modular robot agents that adapt to changing conditions for living architecture. Researchers at Princeton University have built a swarm of interconnected mini-robots that “bloom” like flowers in response to changing light levels in an office. According to their new paper published in the…
