• The ATV is about the size of a traditional London double-decker bus.

• Propulsion Module. It has four main engines and 20 smaller thrusters for attitude control.

• Docking and refuelling system. The „nose“ contains the rendezvous sensors and Russian-made docking equipment. It also has eight thrusters to complement the propulsion system.

• Integrated Cargo Carrier. Attaches directly to the space station and can store up to eight standard payload racks.

• Four solar arrays. Provide electrical power to rechargeable batteries for eclipse periods. ATV can fully operate with the 4800 W generated by its solar wings, equivalent to the electricity used by a typical water heater at home.

• Protection Panels. Protect against micrometeoroid and orbital debris.
