In the coming years, fleets of orbit-policing spacecraft could zip around the planet, keeping an eye on space tech ventures by China, Russia, and ill-intentioned actors elsewhere in the world. The mobile spacecraft concept presents a major shift away from the old-school way of doing things in space, in which satellites maintain simple orbits and try to avoid one another. Soon, those simple satellites will be looked after—and possibly hunted by—more agile spacecraft.

A first-of its-kind space weather "tabletop" exercise has revealed major weaknesses in America's preparedness for severe solar storms. In May 2024, participants representing local and national government agencies gathered at the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland, and at a Federal Emergency Management Agency (FEMA) site in Denver, Colorado, to learn how ready they were for a major solar storm.

Before Russia invaded Ukraine, Dnipro-based entrepreneur Misha Rudominski was chasing his childhood space dream as he raised a funding round to scale up his rocket company Promin. Then, when Russian tanks crossed Ukraine’s borders, Promin’s investors got cold feet and Rudominski’s priorities changed.

A dramatic aircraft chase of a falling spacecraft has provided new insights into the fiery processes that accompany the atmospheric demise of retired satellites. The measurements will help scientists better understand how satellite air pollution affects Earth's atmosphere. In early September last year, a team of European scientists boarded a rented business jet on Easter Island to trace the atmospheric reentry of Salsa, one of the European Space Agency's (ESA) four identical Cluster satellites.

Helium-filled aerostats anchored along the frontlines of eastern Ukraine have become an indispensable component of the country’s defense infrastructure. They enable reconnaissance and kamikaze drones to reach more distant targets, and help Ukrainian forces find enemy drone-control ground stations tens of miles away. Projects are already underway to use these floating watch towers as hubs for interceptor drones, ready to take down the enemy’s unmanned aerial vehicles as they approach.

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
