Buenos Aires big picture

ESA astronaut Thomas Pesquet is spending six months on the International Space Station on his Proxima mission. In his free time, like many astronauts, he enjoys looking out of the Cupola windows at Earth. This collage shows Buenos Aires in Argentina. 

Thomas asked to have the series of highly zoomed pictures aligned into this mosaic to show the city in detail. The 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. Download the high-resolution versions to zoom in and explore.
