Green River grouping

ESA astronaut Thomas Pesquet spent six months on the International Space Station as part of his first mission Proxima. In his free time, like many astronauts, he enjoys looking out of the Cupola windows at Earth. This collage of pictures shows Green River, a tributary of Colorado River in Utah, USA.

Thomas asked to have the series of highly zoomed pictures aligned into this collage to show the river in detail. The International Space Station flies at roughly 400 km altitude so Thomas used the longest lens available onboard: 1150 mm.

On the ground, the images were digitally rotated and assembled into this large collage.
