Great Wall of China

ESA astronaut Alexander Gerst took this photo from the Cupola on the International Space Station on 19 June 2018. Gerst posted the image on social media with the comment: "I think I finally found the answer to a question I've been asked a 1000 times. "Can we see the Great Wall of China from the ISS?" Next to impossible with the naked eye. But I tried with an 800 mm tele lens. Still tough to spot. What do you think, is this it?"

Alexander Gerst is currently on his second mission to the International Space Station for Expeditions 56 and 57. The mission is part of ESA’s vision to use Earth-orbiting spacecraft as a place to live and work for the benefit of European society while using the experience to prepare for future voyages of exploration further into the Solar System.
