Astronaut Jessica Meir aboard ISS captured the Earth, from the window of the Cupola. The Cupola is an ESA-built observatory module of the ISS. Its 7 windows are used to conduct experiments, dockings and observations of Earth. The Cupola provides an observation and work area for the ISS crew giving visibility to support the control of the space station remote manipulator system and general external viewing of Earth, celestial objects and visiting vehicles.
