NASA’s TRACERS Satellites Begin Solar Wind Study Despite SV1 Glitch

NASA’s TRACERS mission twin satellites were launched on July 23, 2025, to study how solar activity causes magnetic reconnection in Earth’s atmosphere. After launch, a power subsystem anomaly had affected one of the satellites (Space Vehicle 1, SV1) on July 25, causing periodic communication loss. NASA said satellite 2 (Space Vehicle 2, SV2) is “healthy,” […]

Solar Sail Spacecraft Could Boost Space Weather Warnings by Nearly 60 Minutes

A potential new solar sail-powered satellite mission is offering an extended early warning of extreme space weather events to safely shut down the most vulnerable pieces of our tech — without waiting for them to fail mid-activity and then figuring out why. Going far beyond Earth in the traditional sense of this type of satellite,
