Anomalous deformation of the Earth's bow shock in the lunar wake: Joint measurement by Chang'E-1 and SELENE

► The Earth's bow shock surface is drastically deformed in the lunar wake. ► In the lunar wake, the bow shock is not maintained due to the highly reduced density. ► The Earth's bow shock survives at 100 km altitude on the lunar dayside. ► Joint measurement by Chang'E-1 and SELENE was performed.
