Expedition 52

Occurred 6 years ago

The Expedition 52 crew explored ways to rebuild bone and prevent further bone loss on Earth and in space and studied the cardiovascular changes that take place on orbit. A new roll-out solar array was deployed for a demonstration and an experiment was installed outside the station to observe neutron stars for new astronomical and navigational insights.

Mission Summary

Get an overview of the Expedition, its crew and the activities they are working on during this mission to the International Space Station.

The Solid Fuel Ignition and Extinction (SoFIE) Growth and Extinction Limits (GEL) experiment aboard the International Space Station (ISS) studies flame growth and extinction in an effort to improve fire safety in space. This image shows a sequence of snapshots taken about 3 seconds apart. During this test point, the ambient oxygen concentration starts relatively high (28%). Initially, the flame is seen as yellow and sooty. As the ambient pressure is reduced, the flame becomes bluer and continues to shrink until fully extinguished. This gives researchers pressure limit data points for flame extinction that could help improve crew and spacecraft safety for future exploration missions.

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."
