ISS and CSS Space Stations brotherhood.
In a rare event and after month of planing and unsuccessful waiting it was possible to catch the ISS-International Space Station and CSS-Chinese Space Station crossing the same region of the sky at approx. the same time.
The upper trail just bellow Ursa Major is the CSS and bellow Polaris and above Cassiopeia the trail of the ISS. Both space stations travel from West to East (Clockwise).
In the foreground the remains of a dramatic landscape of the abandoned chemical complex of Achada do Gamo -Portugal.
God speed ISS and CSS.
