Expedition 71 Resources

For nearly a quarter of a century the International Space Station (ISS) has hosted crews and accommodated science experiments even as it has continued to evolve into the highly capable orbiting laboratory of today. With its unique vantage point, the ISS serves as an intersection for discoveries ranging from the vast, such as the search for dark matter and cosmological origins, to the near, such as detailed observation of our home planet and its atmosphere, to the microscopic, including behavior of microbial life, DNA sequencing, and molecular biology in the microgravity environment. The Expedition 71 patch celebrates this science as well as the thousands of multinational scientists and technicians that have contributed to numerous groundbreaking experiments. The ISS is the ultimate destination for the scientifically curious. The symbology represents onboard research into quantum behavior of novel states of matter, antibodies and immune function, the search for dark matter, flame and combustion physics, DNA expression, plant growth and root behavior, and direct earth observation. The human eye and microscope objectives at upper left form the apex of a cone of vision culminating in the Expedition number 71, and represents the deliberate and disciplined practice of scientific observation. Earth’s moon and Mars are also depicted as next steps for exploration, with an anticipation of further rich scientific discovery using many techniques and skills honed aboard the ISS.

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."
