ISS038-E-000246 (12 Nov. 2013) --- Equipped with seven windows, the Cupola aboard the International Space Station probably has exponentially more beneficial facets than it has windows. Seldom seen without at least two or three heads and bodies near the windows, the facility is either temporary or permanent home to robotics controls, computers and cameras among other hardware. And needless to say, it affords spectacular viewing ports for crew members.

ISS039-E-005744 (30 March 2014) --- By the rationale of some observers, this image of Expedition 39 Flight Engineer Steve Swanson could be titled "Return to the Old Stomping Grounds, Five Years Hence," except for the fact that it is difficult to stomp in a weightless environment and the fact that the Cupola was not part of the orbital outpost in March of 2009, the last time Swanson visited it. The NASA astronaut and two Russian cosmonauts arrived at the station on March 27, 2014, and this image of a jubilant Swanson was one of the first showing members of the second aggregate of the Expedition 39 crew.

iss038e013587 (12/8/2013) --- A view of the Cupola module aboard the International Space Station (ISS). The cupola is a small module designed for the observation of operations outside the station such as robotic activities, the approach of vehicles, and spacewalks. Its six side windows and a direct nadir viewing window provide spectacular views of Earth and celestial objects. The windows are equipped with shutters to protect them from contamination and collisions with orbital debris or micrometeorites. The cupola house the robotic workstation that controls the Canadarm2.
