About this launch
Hera is a space mission in development at the European Space Agency in its Space Safety program. Its primary objective is to study the Didymos binary asteroid system that was impacted by DART and contribute to validation of the kinetic impact method to deviate a near-Earth asteroid in a colliding trajectory with Earth. It will measure the size and the morphology of the crater created by and momentum transferred by an artificial projectile impacting an asteroid, which will allow measuring the efficiency of the deflection produced by the impact. It will also analyze the expanding debris cloud caused by the impact.

Brake! Time for ESA’s Hera asteroid mission to go slowLaunched two years ago today, the European Space Agency’s Hera mission for planetary defence has been hurtling away from Earth ever since. The small-car-sized spacecraft is now preparing for its single most challenging activity since lift-off: the sustained braking manoeuvres to slow it down to approach its target asteroids.
The Incredible Adventures of the Hera mission – The space detectives arriveMeet Hera, our very own asteroid detective. Together with two CubeSats – Milani the rock decoder and Juventas the radar visionary – Hera is off on an adventure to explore Didymos, a double asteroid system that is typical of the thousands that pose an impact risk to planet Earth.
Finding Hera’s way: ESA’s Flight Dynamics team into actionThe European Space Agency’s Hera planetary defence mission team is preparing to light a fire in the sky. On the early morning of 15 October the small-car-sized spacecraft will burn its Orbit Control Thrusters in the direction of its target asteroid system for a total of 93 minutes continuously. This braking manoeuvre will bring it near to matching the orbital velocity of the Didymos binary asteroids.

A hitchhiker’s guide to Hera’s target asteroidsCurrently speeding through deep space at 12 km/s relative to Earth, ESA’s Hera spacecraft is due to reach its target Dimorphos asteroid this November. But if an astronaut were magically teleported onto the small-car-sized Hera upon arrival, what would they be seeing, and what would it feel like to walk on the asteroid’s surface?

Name our dino – ESA’s Hera asteroid mission mascot!The European Space Agency’s Hera asteroid mission for planetary defence has a cartoon dinosaur for its mascot – because dinos were made extinct after an asteroid impact, but while they didn't have a space agency, people do! Now we’re asking you to supply our dino with a name, to win a place at November’s Hera arrival celebration.
