nuclear monitoring

United States officials conducted a test in Nevada aimed at improving algorithms used to detect nuclear activity. The exercise reportedly supplied data that helps sharpen the country's capabilities for identifying nuclear tests or weapons. It highlights ongoing American investment in nuclear monitoring technology at a time of heightened global arms tensions.

A test is being conducted in Nevada aimed at improving United States nuclear-detection algorithms, according to a report from Ukrainian technology outlet Mezha. The exercise is intended to refine the software systems used to identify nuclear-related events. Further details about the test's scope, participants, or timing were not provided in the report.

The United States has decommissioned its Defense Support Program (DSP) satellites, the long-serving infrared constellation built to detect missile launches and nuclear detonations. The satellites, launched since the 1970s, are being retired as newer Space Based Infrared System (SBIRS) spacecraft take over the deterrence monitoring mission, marking the end of a decades-old strategic early-warning program.

US national security adviser Mike Waltz said President Trump will end Iran's pursuit of a nuclear weapon, renewing hardline rhetoric over Tehran's nuclear programme. The statement drew attention amid ongoing tensions over Iran's nuclear activities and international monitoring, with observers weighing whether it signals a tougher American approach toward the Islamic Republic.

NATO is moving to calm tensions ahead of a planned nuclear exercise in Italy, stressing that the drill is routine and not directed at Moscow. A senior NATO official said the alliance's aim is to keep things calm and avoid any misunderstanding with Russia, which monitors Western nuclear exercises closely amid ongoing strain over the war in Ukraine.

A new analysis argues that a nuclear crisis could start not with a dramatic event but with silence in space, such as the loss of satellite communications or early-warning capabilities. The piece examines how gaps in space-based monitoring and communication between nuclear-armed states could escalate misunderstandings into dangerous confrontations, urging better resilience and communication safeguards in orbit.

Monitors have detected what officials describe as significant activity at an Iranian nuclear facility that was damaged in strikes during the early stages of the recent war between Israel and Iran. The activity is raising questions about whether Iran is repairing the site or resuming work there, and it comes as tensions over Tehran's nuclear program remain high.

The United States is upgrading the sensors on its satellites that detect nuclear explosions, according to a report by Eurasia Review. These sensors, originally developed to monitor compliance with nuclear test bans, can spot the characteristic radiation and light signatures of an atomic blast from orbit. The modernisation comes amid renewed global attention to nuclear readiness and arms control.
