It's a shame that the spacecraft the ESA don't go at the same time that NASA, but still is one of the more important mission in next years...

Hera is not primarily known as the goddess of marriage, though indeed she was that. She is primarily known at the queen of the gods, who Zeus cheated on on a regular basis. That part ought to be amended I think, not "goddess of marriage" but "queen of the Olympian Gods"

ESA plans mission to smallest asteroid ever visited

ESA’s planet-defending Hera mission will set a new record in space. The asteroid investigator will not only be the first spacecraft to explore a binary asteroid system – the Didymos pair – but the smaller of these two worldlets, comparable in size to Egypt’s Great Pyramid of Giza, will become the smallest asteroid ever visited.

Hera is currently under study to be presented for approval by ESA’s Space19+ Council meeting of European space ministers. It is planned for launch in 2023.

Close encounters: planning for extra Hera flyby

Quote
ESA’s proposed Hera mission will already visit two asteroids: the Didymos binary pair. The Hera team hopes to boost that number by performing a flyby of another asteroid during the mission’s three-year flight.

The opportunity arises because Hera will be flying out to match Didymos’ 770-day orbit, which circles from less than 10 million km from Earth to out beyond Mars, at more than double Earth’s distance from the Sun.

In the process Hera will pass both multiple near-Earth asteroids and the inner edge of the main Asteroid Belt. Initial studies at ESA’s European Space Operations Centre have turned up dozens of candidate asteroids across different mission scenarios.

ESA's Hera asteroid mission borrows eyes of NASA's Dawn

Quote
The mission to the smallest asteroid ever explored will employ the same main camera as the mission to the largest asteroids of all. ESA’s proposed Hera spacecraft to the Didymos asteroid pair has inherited its main imager from NASA’s Dawn mission to the Vesta and Ceres asteroids.

... the Asteroid Framing Camera (AFC) Hera will use to navigate through space and survey its targeted double asteroids is already built and ready. Two of these cameras – Hera will carry a pair, for redundancy – are sitting in protective nitrogen gas inside a clean room in Göttingen, Germany.
