Hera will perform a swingby of Mars in March 2025 as a way of gathering extra momentum on its way to the Didymos binary asteroid system. The spacecraft will fly within the orbits of both Martian moons Deimos and Phobos, and perform science observations of the former body and the planet's surface, in synergy with the UAE's Hope orbiter and gathering preparatory data for JAXA-DLR's MMX Martian Moons eXploration mission due to be launched in 2026.
