ESA's Juventas CubeSat will house the smallest space radar, JuRa, for the Hera mission, aiming to image inside the asteroid Dimorphos. Developed by IPAG and EmTroniX, it builds upon technology from ESA’s previous Rosetta mission. The smallest radar to fly in space has been delivered to ESA for in
will perform the first-ever radar sounding inside an asteroid. Juventas will peer up to 100 m deep within the 160-m-diameter Dimorphos moonlet of the 780-m-diameter Didymos asteroid.
CubeSats are mini-satellites built up from standardized 10-cm boxes. Juventas is a ‘6-unit’ CubeSat, measuring 10x20x30 cm, while the Juventas radar instrument – JuRa – for short measures 9.5×9.5×9.5 cm across, able to fit within a single CubeSat unit, along with a quartet of 1.5 m-long radar antennas – which will deploy like metal tape measures and have been manufactured by Astronika in Poland.
