Observing #Earth - ISS Expedition 13

A setting sun and the thin blue airglow line at Earth’s horizon was captured in this image photographed by an Expedition 13 crew member from a window on the International Space Station in April 2006.


One of the long-standing experiments on the International Space Station is called Crew Earth Observations. The unique vantage point of Earth from space has allowed astronauts to capture some of the most compelling photographs ever seen. They are not only beautiful photographs, but also offer insight into how the planet is changing over time, from human-caused changes like urban growth and reservoir construction, to natural dynamic events such as hurricanes, floods and volcanic eruptions. Crew members have been photographing Earth from space since the early Mercury missions beginning in 1961. The continuous images taken from the space station ensure this record remains unbroken.


In celebration of Earth month, Marshall has posted images on Instagram of our planet beginning with Expedition 1 from 2000 all the way through the current Expedition 47.
