Astronaut Reid Wiseman on the International Space Station shared this image of Earth earlier Sunday morning tweeting, "Clouds cast thousand-mile shadows into the black of #space
. A favorite view of ours."
Beginning with the Mercury missions in the early 1960s, astronauts have taken photographs of the Earth. Today, the International Space Station (ISS) continues the NASA tradition of Earth observation from human-tended spacecraft. Operational since November 2000, the ISS is well suited for documenting Earth features and provides an excellent stage for observing most populated areas of the world. Images coming down from the International Space Station are processed on a daily basis and include over 1.2 million images through Nov. 1, 2013.
