2. The international Space Station is a microgravity laboratory. A crew of six occupies the station at all times, traveling at the speed of five miles a second, orbiting the Earth every 90 minutes. The ISS was first Launched in 1998.

3. The space station has been continuously occupied since 2000. More than 200 people from 15 countries have visited the station. Partner ships Include the US, Russia, Japan and Canada.

4. The crew spends about 35 hours each week performing research about the Earth, Space, Physical, and Biological sciences.

5. The station operates as a national laboratory for scientific research.

6. More than an acre of solar arrays provide power to the station, making it the second brightest thing in the night sky other than the Moon. It has taken 13 years and about $150 billion to build and fly the ISS. Periodically, the ISS will have to be boosted to maintain its height, due to atmospheric drag.

7. The space station allows research and technology developments that will benefit human and robotic exploration beyond low-orbit Earth such as asteroids and Mars.

8. The space station has an internal pressurized volume of 32,333 cubic feet. The solar array is 240 feet long. The space station weighs approximately 925,000 pounds. The space station measure 357 feet end to end.

9. Fifty-Two computers run the systems on the ISS. There is 3.3 million lines of software code on the ground support 1.8 million lines of flight software code. Eight miles of wire connects the electrical power.
