Observing #Earth - ISS Expedition 46
A photo taken by NASA astronaut Scott Kelly during his One Year Mission to the International Space Station clearly shows the snow-covered east coast of the United States. Taken in January 2016, the picture also shows the line separating the land from the Atlantic Ocean shortly before sunrise.
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.
