Chernobyl’s containment tested as war reaches the haven of safety

The New Safe Confinement arch built to shield Reactor No. 4 at Chernobyl faces renewed jeopardy after a 2025 drone strike damaged the structure, sparking warnings from the IAEA that its safety function could be compromised and that dismantling work may be delayed by war-related disruption. Despite no immediate rise in local radiation, the incident highlights how the invasion has upended assumptions about nuclear safety and cleanup timelines, reviving memories of the 1986 disaster for staff who have endured decades of exposure and duty at the site.

Cosmic-ray “cavity” between Earth and Moon could reshape lunar missions

A study using data from China’s Chang’e-4 lander identifies a region of reduced galactic cosmic-ray radiation in Earth–Moon space—a cavity that appears during the Moon’s local morning. The lower-energy protons drop by about 20% in this window, likely caused by Earth’s magnetosphere extending farther than previously thought. If confirmed, this timing could help plan safer lunar surface operations for upcoming missions (including Artemis II) by reducing astronauts’ radiation exposure. The findings are published in Science Advances (2026).
