ESA astronaut Alexander Gerst took this image from onboard the International Space Station. He posted it on social media ten days into his mission Horizons, commenting: "Horizon. Today first day off after some of the busiest 10 days in my life. I thought long about which should be my first photo from space. When I saw this sunrise, I immediately knew this would be it. What a fascinating planet."
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.
