Mission Science

Learn more about the range of microgravity science encompassing human research, space phsyics, and more the Expedition 12 crew has conducted.

One of the Expedition 41 crew members aboard the International Space Station, flying at an altitude of 222 nautical miles above a point in the Atlantic Ocean several hundred miles off the coast of Africa near the Tropic of Cancer, photographed this eye-catching panorama of the night sky and the Milky Way on Sept. 27. NASA astronaut Reid Wiseman, flight engineer, tweeted the image, which was taken with an electronic still camera, set with a 24mm focal length. In his accompanying comments, Wiseman stated, "Sahara sands make the Earth glow orange."
