Hera is a candidate mission that will be humankind's first probe to closely investigate a binary asteroid system. It will find out more about this type of asteroid and explore asteroid deflection. This infographic describes the Hera mission from beginning – NASA launching the partner mission, DART – to end – Hera landing on asteroid Didymos.
Along the way, Hera will carry out lots of science, including measuring the properties of the asteroid and investigating the crater left by DART crashing into the asteroid’s surface. It will also demonstrate some impressive new technologies.
