ESA astronaut Alexander Gerst from Germany will shortly be returning to Earth after a long-duration stay on board the International Space Station (ISS). The Horizons mission coincided with the 20th anniversary of the start of ISS construction in orbit. During the mission, Alexander carried out a wide range of scientific experiments and took part in ISS operations – as well as becoming the second European commander of a Station expedition.
