Below is a youtube video about the International Space Station; really interesting and informative.
NASA astronaut Sunita Williams is a captain in the U.S. Navy. She first launched into space in 2006 and spent 195 consecutive days in space, setting a record for the longest single spaceflight by a female astronaut.
On Dec. 9, 2006, Williams launched into space for the first time on board the shuttle Discovery as part of the 14th expedition to the ISS. She remained in space until April 26, 2007. While in space, Williams participated in the Boston Marathon, clocking the 26.2-mile (42-kilometer) race on the ISS’ treadmill in 4 hours, 23 minutes, 10 seconds — the first time an entrant has competed in the race from orbit.
On July 14, 2012, Williams traveled to the International Space Station again. In September 2012, Williams became the second woman to assume command of the ISS.
In her final days as Commander of the International Space Station, Williams of NASA recorded an extensive tour of the orbital laboratory and downlinked the video on Nov. 18, 2013, just hours before she, cosmonaut Yuri Malenchenko and Flight Engineer Aki Hoshide of the Japan Aerospace Exploration Agency departed in their Soyuz TMA-05M spacecraft for a landing on the steppe of Kazakhstan. The tour includes scenes of each of the station’s modules and research facilities with a running narrative by Williams of the work that has taken place and which is ongoing aboard the orbital outpost.
The International Space Station, is a $100 billion research complex involving 15 countries and orbiting 250 miles (410 km) above Earth.
Since the retirement of the U.S. space shuttles in 2011, the United States is dependent on Russia to fly astronauts at a cost to the nation of $60 million per person.
