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,”…
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,…
The Parker Solar Probe has truly achieved a historic milestone in solar exploration. In July 2025, NASA released the closest-ever images of the Sun, taken just 3.8 million miles from its surface. On Dec. 24, 2024, Parker flew 3.8 million miles from the Sun’s surface, entering the outer corona. During this pass, Parker’s Wide-Field Imager…
