The Planck spacecraft mated with its launcher
Date: 23 Apr 2009
Still attached to the arms of the vertical lifting device, this image was taken just after mating of the Planck spacecraft on top of the Ariane 5 ECA launcher. The golden-yellow ring attached to the base of the spacecraft's service module is the launcher adapter ring (Adaptateur Charge Utile, or ACU). The ACU has a diameter of 2.624 m and is secured to the launcher through a 0.78m-high adapter cone, composed of a strong carbon structure and two aluminium rings. Seen running as an iris around the adapter cone is the top of the Vehicle Equipment Bay (VEB).
