Space weather may intensify in the coming decades with more frequent solar flares and eruptions to batter the planet. Whilst Earth's technology, including satellites and power grids, is likely to feel the squeeze, some of the effects might be surprisingly positive. The current solar cycle, the 25th since records began, may have just recently passed its peak. Monthly numbers of sunspots, solar flares and eruptions are now set to gradually decline.

Axiom Space will launch two orbiting data center nodes into low Earth orbit by the end of this year, as the first step in the development of off-planet computing infrastructure. The two satellites will be part of the upcoming optical relay constellation by Canada-headquartered Kepler Communications, which is expected to begin launching in late 2025.

At least three old satellites or rocket bodies fall back to Earth every day, a new report reveals. And experts warn that the number of objects returning from space is set to increase, a possible concern for the health of Earth's atmosphere and for the safety of humans on the ground. The Space Environment Report, released by the European Space Agency (ESA) on April 1, found that some 1,200 "intact objects" reentered the atmosphere in 2024, in addition to countless space debris fragments.

From satellite TV broadcast hijacking to jamming and spoofing of satellite navigation systems, attacks on space-based services are on the rise. Experts are racing to find solutions to keep the onslaught in check. On Dec. 25 of last year, an Azerbaijani plane headed for the Chechnyan capital Grozny crash-landed in Kazakhstan after flying into a GPS jamming bubble.

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.

Within three years, #Ukraine has become the most mine-contaminated country in the world. Clearing up the lethal war residues will take decades, unless new technologies are developed. My feature in @EandTmagazine https://t.co/DgU14p1pHu
Delighted to see this story out. The war in #UkraineRussiaWar has sparked an innovation race that is making fast progress towards a sci-fi like world of autonomous killer #drones fighting similar machines made by the adversaries. https://t.co/cPJmzhWrzZ
A planned clean hydrogen plant could increase the night sky brightness above the Very Large Telescope, one of the world's most powerful sky observing machines, by a whopping 35 percent. #lightpollution #astronomy https://t.co/BjBkW798To
