Sunset Over the Gulf of Mexico

From the International Space Station, Expedition 42 Flight Engineer Terry W. Virts took this photograph of the Gulf of Mexico and U.S. Gulf Coast at sunset and posted it to social media on Dec. 14, 2014. The space station and its crew orbit Earth from an altitude of 220 miles, traveling at a speed of approximately 17,500 miles per hour. Because the station completes each trip around the globe in about 92 minutes, the crew experiences 16 sunrises and sunsets each day. Image Credit: NASA/Terry Virts

Wikipedia: International Space Station (ISS)

The International Space Station (ISS) is a space station, or a habitable artificial satellite, in low Earth orbit. It is a modular structure whose first component was launched in 1998. Now the largest artificial body in orbit, it can often be seen with the naked eye from Earth. The ISS consists of pressurised modules, external trusses, solar arrays and other components. ISS components have been launched by American Space Shuttles as well as Russian Proton and Soyuz rockets. In 1984, the ESA was invited to participate in Space Station Freedom. After the USSR dissolved, the United States and Russia merged Mir-2 and Freedom together in 1993.

The ISS serves as a microgravity and space environment research laboratory in which crew members conduct experiments in biology, human biology, physics, astronomy, meteorology and other fields. The station is suited for the testing of spacecraft systems and equipment required for missions to the Moon and Mars.
