The International Space Station (ISS) is a large space laboratory that orbits Earth. It was built by many countries working together and is used by astronauts to do science experiments in space. The ISS travels very fast and goes around the Earth many times a day. It has many parts and looks like a giant machine in the sky. People often wonder how big this space station really is.
An Overview of ISS
The International Space Station is a large space laboratory that orbits Earth. It is built and operated by five space agencies from 15 countries, including NASA, Roscosmos, JAXA, ESA and CSA. Since November 2000, astronauts have lived and worked there non-stop. Let’s explore some interesting facts and learn about the area and size of the ISS.
Size of the International Space Station
The ISS is a huge structure in space. From one end to the other, it is 356 feet (109 meters) long. This almost as long as an American football field, including the end zones. It includes large modules, long solar panels and many attached parts. The station is made of many parts that were sent into space and joined together during 42 missions.
Area and Volume of the ISS
The International Space Station is about 356 feet and 240 feet wide, making it slightly larger than a football field. Its total area is around 13,000 square feet. It takes six crew members working 356 days a year, or 52,560 crew hours, to keep the ISS running smoothly in space.
The ISS is not just long – it also has a big living and working space. The total pressurized volume (inside space with air) is 1,005 cubic meters (35,491 cubic feet). The habitable volume, where astronauts can live and move around, is 388 cubic meters (13,696 cubic feet). This is bigger than a six-bedroom house!
How Fast and Far the ISS Travels?
The ISS moves very fast – 5 miles per second (about 28,000 km/h). It orbits Earth 16 times every 24 hours, which means astronauts see 16 sunrises and 16 sunsets each day! In just one day, it travels a distance almost equal to a trip from Earth to the Moon and back.
Life on the Space Station
Up to seven astronauts live and work on the ISS. Sometimes, more are present during crew changes. They stay busy with science experiments, spacewalks and daily workouts to stay healthy in microgravity. They also take photos – over 3.5 million pictures of Earth have been taken from the ISS.
Amazing Technology and Design
- The ISS has over 50 computers running everything.
- More than 1.5 million lines of software code help manage data, temperature, air and more.
- 8 miles of wires connect the station’s power systems.
- A robotic arm called Canadarm2, which is 55 feet long, helps with repairs and experiments.
