This antenna will send back the first close-up images of the distant #Dimorphos #asteroid since its orbit was shifted by an impact with @NASA@twitter.com & @JHUAPL@twitter.com's #DARTMission. The High Gain Antenna of @ESA@twitter.com's #HeraMission is being tested at #ESATech centre #ESTEC https://www.esa.int/ESA_Multimedia/Images/2022/12/How_Hera_asteroid_mission_will_phone_home

This antenna will also do the radio science to measure the mass of #Dimorphos and give a better value for how efficient the #DARTMission impact was at pushing it around.
