Powerful X-class solar flare triggers radio blackout ahead of Artemis 2 launch

AI-summarised brief · reviewed before publication

A powerful X1.4 solar flare erupted from the sun on March 30, triggering radio blackouts on Earth and raising concerns for NASA's Artemis 2 mission preparations. The flare peaked at 11:19 p.m. EDT and caused widespread degradation of high-frequency radio signals across the sunlit side of Earth. A coronal mass ejection (CME) was also launched, with a possible Earth-directed component, potentially impacting the mission's radio communications and aurora visibility at lower latitudes.
