The logo for the Alissé mission
features the wing of a bird enclosing images of the ISS and Shuttle Discovery, either side of two sets of horizontal lines. The horizontal lines symbolise different aspects of the mission. The two sets of lines represent the two spacewalks to be undertaken by Christer Fuglesang during the mission. The bird's wing adds to this symbolism of the spacewalks as Fuglesang will seem to be flying around the ISS almost like a bird without the constraints of gravity.
The horizontal lines further evoke the wind alizé, through which the Shuttle flies in the logo to reach the ISS. The two sets of lines symbolise the Shuttle and ISS in their separate orbits as they close for docking. The lines also represent the two ESA astronauts on the Station during the mission.
The four individual lines also suggest the four space agencies of the astronauts on the Station during the mission. The bird's wing and the symbols it encompasses also suggest how a bird looks down on Earth, while floating on the alizé wind, similar to how the astronauts will be looking down on Earth from space.
The left-hand part of the ESA logo suggests the Moon as a future step for ESA, with respect to its exploration goals, built on its current and past missions to the ISS. The name of the mission is at the bottom, with the letters 'ISS' highlighted to suggest the mission's target.
