Each identical EscaPADE spacecraft has a mass under 90 kg. The spacecraft bus is 60 x 70 x 90 cm. The spacecraft is powered by two 480 x 70 cm solar panel wings extending from opposite sides of the spacecraft. These charge batteries and power the solar-electric propulsion system. Cold gas thrusters are used to maintain orientation. Communications are in X-band via a 60 cm diameter dish antenna. A 90 cm boom extends above the spacecraft holding some of the science instruments.
