The world at large is working to stop the fast-progressing degradation of Earth's environment. In the space sector, however, one-use-only products still reign supreme. The advent of megaconstellations has, in fact, accelerated the rate at which the space industry burns through resources, shifting from big satellites with decades-long lifespans to cheaper birds designed to expire within a few short years.

After the Estonian startup KrattWorks dispatched the first batch of its Ghost Dragon ISR quadcopters to Ukraine in mid-2022, the company’s officers thought they might have six months or so before they’d need to reconceive the drones in response to new battlefield realities. The 46-centimeter-wide flier was far more robust than the hobbyist-grade UAVs that came to define the early days of the drone war against Russia.

Crucial research into the effects of rocket and satellite air pollution on Earth's atmosphere is reportedly being cut as part of Donald Trump administration's cuts to climate science budgets. Experts say the cancellation comes at the worst time and will cause a major setback for the emerging field of science.

An extreme solar storm hit Earth some 14,300 years ago, more powerful than any other such event known in human history, a new analysis of radiocarbon data has revealed. The solar storm, the only known to have taken place in the last Ice Age, long eluded scientists as they lacked appropriate models for interpreting radiocarbon data from glacial climate conditions.

As a defensive contrivance, walls are about as old as warfare itself. Think of Hadrian’s Wall, China’s Great Wall, and the castles and battlements of the Middle Ages, for starters. But can a wall be effective against modern first-person-view drones, which have killed thousands, possibly tens of thousands, in the war in Ukraine? It turns out it probably can—if it’s a “wall” consisting of thousands of jammers.

Last September, a team of European researchers executed a dramatic aircraft chase of a falling piece of #spacedebris - now they have released the first results from these observations that provide new insights into satellite #airpollution. https://t.co/HLkpbguvdP
I am in awe of Ukrainian ingenuity and honoured that I have the privilege to cover their defence-tech developments. It's mind-boggling to think how much they have achieved in three years. #Ukraine #drones #defense #innovation #airships https://t.co/yeFKbfB2Lz
I really like "tech that helps stories." In Cambodia, 40-year-old satellite images are now helping to find forgotten mine fields. https://t.co/7pzuwIXHvy #demining @TheHALOTrust
