Hera Mission: Why should we study the Didymos asteroid system? | ESA
The Hera Mission will fly to a unique target among the 1.3 million known asteroids of our Solar System—the first body to have had its orbit shifted by human action—to probe lingering unknowns related to its deflection. The European Space Agency Hera mission was successfully placed on an interplanetary transfer orbit by a SpaceX Falcon 9 rocket launched from Cape Canaveral in Florida, USA, on October 7, 2024.
Hera will carry out the first detailed survey of a ‘binary’—or double-body—asteroid, 65803 Didymos, that is orbited by a smaller body, Dimorphos. Hera’s main focus will be Dimorphos. Its orbit around the main body was previously altered by NASA’s kinetic-impacting DART spacecraft. Launched in 2021, NASA's DART spacecraft successfully collided with Dimorphos on September 26, 2022, at about 11 million kilometers (6.8 million miles; 0.074 astronomical units; 29 lunar distances) from Earth.
The Hera Mission has 18 participating European Space Agency (ESA) Member States plus Japan (supplying the TIRI instrument). Notably German industry is leading the mission, while Italy is providing the propulsion and Spain and Romania developed Hera’s innovative guidance, navigation and control system. The Hera Science Team involves scientists from all ESA Member States, Japan, the US and other non-European countries.
