Cupola is a module of the ISS attached to the Tranquility node and consists of a cluster of seven windows in a dome shape. Built by ESA and launched on 8 February 2010, its overall diameter is 2.95 m and its height is 1.5 m. Its central window measures 80 cm across. Cupola faces towards Earth and its windows, made from fused silica and borosilicate glass, provide the crew with excellent visibility for external ISS activities, such as the operation of the main robotic arm, Canadarm2.
