As the most expensive thing ever constructed by humans, this .gif makes it seem surprisingly simple.
The International Space Station is not only an orbiting laboratory, but also a space port for a variety of international spacecraft. As of November 2014, there have been:
- 100 Russian launches
- 37 Space Shuttle launches
- 1 test flight and 3 operational flights by SpaceX’s Dragon
- 1 test flight and 2 operational flight by Orbital Science’s Cygnus
- 4 Japanese HTVs
- 5 European ATVs
A total of 184 spacewalks have been conducted in support of space station assembly totaling over 1,152 hours, or approximately 48 days.
The space station, including its large solar arrays, spans the area of a U.S. football field, including the end zones, and weighs 924,739 pounds. The complex now has more livable room than a conventional six-bedroom house, and has two bathrooms, a gymnasium and a 360-degree bay window.
