    Our Hera spacecraft can now see Didymos and Dimorphos as two separate asteroids! Coming closer, it will study the effects of NASA's 2022 DART impact and help advance asteroid deflection as a planetary defence technique. The first detailed images of Dimorphos are expected on 25 November. Follow Hera’s journey with the Hera Space Companion 👉 🔗

    Another successful step on Hera’s approach to Didymos and Dimorphos. 🎯
    ESA's Hera mission @ESA_Hera
    Hera’s second braking manoeuvre yesterday proved successful, reducing the spacecraft’s velocity relative to the Didymos and Dimorphos system by 70 m/s from a distance of 2300 km away. Some 90% of the 31-minute thruster firing took place in the early morning, followed by a cross-check of performance, with the remaining 10% occurring that afternoon. Hera is now moving at 20 m/s relative to the asteroids; a trio of smaller ‘transition’ manoeuvres this coming week will reduce Hera’s relative velocity down to near zero.
