Expedition 15

Occurred 16 years ago

The Expedition 15 crew evaluated ways to measure an astronaut's exposure to cosmic radiation and explored how nutrition, vitamins, and medicine may offset the effects of living in space, as well as returning to Earth. The crew also tested a handheld device for the rapid detection of biological and chemical contamination on the space station.

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."
