iss050e020100 (12/28/2016) --- European Space Agency (ESA) astonaut Thomas Pesquet preparing to take Crew Earth Observations (CEO) photos from the Service Module (SM) window. Cosmonaut Oleg Novitskiy is visible in the background. CEO imagery provides researchers on Earth with key data to understand the planet from the perspective of the ISS. Crew members have been photographing Earth from space since the early Mercury missions beginning in 1961. The images taken from the ISS ensure this record remains unbroken.
