This image of the Moon and Earth was taken by ESA astronaut Alexander Gerst from the International Space Station during his Horizons mission. He posted it on social media, commenting: "By orbiting the Earth almost 16 times per day, the International Space Station crew travel the distance to the Moon and back – every day."
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.
