Based on magnetic field and plasma measurements from the Mars Atmosphere and Volatile EvolutioN (MAVEN) mission, we present the first observation of magnetic reconnection occurring between the closed crustal magnetic field and the Ion Composition Boundry(ICB) at the dayside of Mars. Notably, distinctive typical features typical of reconnection, such as the Hall magnetic field and plasma outflow, have been unambiguously detected. Our findings robustly support the occurrence of reconnection at Mars, specifically highlighting the interaction between the interplanetary magnetic field in the induced magnetosphere and the closed crustal magnetic field. This reconnection event induces significant alterations in the magnetic field topology, exerting a profound influence on the escape dynamics of ions.
