INTERNATIONAL SPACE STATION(ISS)
PC - NASA
Five space agencies including NASA, JAXA, ROSCOSMOS, CSA, ESA have contributed to the space station assembly.
The International Space Station is larger than a six-bedroom house with six sleeping quarters, two bathrooms, a gym, and a 360-degree view bay window.
- In 24 hours, the space station makes 16 orbits of Earth, traveling through 16 sunrises and sunsets.
- Peggy Whitson set the U.S. record for spending the most total time living and working in space at 665 days on Sept. 2, 2017.
- To mitigate the loss of muscle and bone mass in the human body in microgravity, the astronauts work out at least two hours a day.
- The solar array wingspan (356 feet, 109 meters) is longer than the world’s largest passenger aircraft, the Airbus A380 (262 feet, 80 meters).
- The space station is 356 feet (109 meters) end-to-end, one yard shy of the full length of an American football field including the end zones.
- A spacecraft can arrive at the space station as soon as four hours after launching from Earth.
- Four different cargo spacecraft deliver science, cargo and supplies: Northrop Grumman’s Cygnus, SpaceX’s Dragon, JAXA’s HTV, and the Russian Progress.
- On-orbit software monitors approximately 350,000 sensors, ensuring station and crew health and safety.
- More than 50 computers control the systems on the space station.
