MAVEN Photographed 3I/Atlas. Then NASA Lost Signal. Here's What Happened.

NASA's Mars Atmosphere and Volatile Evolution (MAVEN) spacecraft ceased communications on December 6, 2024, following routine planetary occultation. This analysis examines the timeline of signal loss, operational context, and budgetary implications surrounding the communication anomaly affecting NASA's primary Mars communications relay system. MAVEN has operated in Martian orbit since September 2014, conducting atmospheric studies and serving as critical communications infrastructure for Curiosity and Perseverance rovers. The spacecraft transmitted normal telemetry immediately prior to occultation, then failed to resume signal transmission upon emergence from Mars shadow as observed from Earth.
