The exterior ATV is a cylinder, 10.3 metres long and up to 4.5 metres in diameter covered in a foil layer and meteorite protection panels.
Characteristic X-shaped solar arrays extend from the spacecraft. Deployed 100 minutes after liftoff, the solar arrays reach a span of 22.3 m. The four arrays are totally independent and can rotate to get the best orientation to the Sun. They are able to produce an average of 4800 watts - providing power to rechargeable batteries which are vital for powering ATV systems when the spacecraft is in the shadow of Earth.
