Space observatory Cupola – a window to space

<p>How do astronauts take their wonderful pictures of Earth from space? ESA astronaut Alexander Gerst demonstrates the European-built Cupola observatory on the International Space Station.</p><p>Offering a full 360° view of Earth and the Space Station, its main purpose is to observe approaching spacecraft and monitor spacewalks. When the Station’s robotic arm is used to dock spacecraft or move astronauts on a spacewalk, the arm is controlled from a command centre inside Cupola. The observatory is also used for visual scientific research of Earth but naturally offers a place for astronauts to relax and take pictures, the bay windows offer the best panoramic view of our world.</p><p>The windows are protected by external shutters, which can be opened by with the simple turn of a button. The shutters are closed when not in use to protect the glass from micrometeoroids and orbital debris, and to prevent solar radiation from heating up Cupola or to avoid losing heat to space.</p><p>Each wind
