This image gallery features the best images taken by ESA astronaut Alexander Gerst during his Blue Dot mission as chosen by his followers on Facebook.

Alexander spent six months on the International Space Station in 2014 to run experiments for scientists on Earth and maintain the weightless research station. His tasks included a spacewalk to upgrade a power supply, overseeing the arrival of ATV Georges Lemaître and installing a new furnace to research metal alloys.

Together with crewmates NASA astronaut Reid Wiseman and Russian commander Maxim Suraev, Alexander took thousands of images of Earth from the Cupola observatory in his free time.
