The International Space Station (ISS) is once again visible in the evening skies over Europe. For several weeks the orbital outpost has only been visible from Europe early in the morning – too early for most!
Under a clear sky, the ISS is visible from the ground when it is still in the sunlight and it is dark down below – either in the dusk, shortly after sunset, or in the dawn, before sunrise. This is illustrated well in this photograph recently posted by ESA astronaut André Kuipers. From the ground the ISS appears as a star-like object moving across the nightsky.
