The International Space Station is an idea for an international cooperative scientific.
environment. The station maintains a low orbit around the Earth. This is 217 to 285 miles.
above the Earth. The station itself is under construction while in orbit. Construction started.
in 1998 and will take years to complete. It is estimated to be completed by the year 2006. .
Sixteen separate nations are working together to complete this massive laboratory. The.
United States is working with Russia, Japan, Canada, Brazil, the United Kingdom, France,.
Germany, Belgium, Italy, the Netherlands, Denmark, Norway, Spain, Switzerland, and.
Sweden. Each country is contributing to the construction of the station. The station is made.
up of more than 100 components and will take 44 more trips with the three main space.
vessels to complete it. It will take nearly 2000 man-hours and nearly 60 space walks to.
construct and maintain the station. After completion, the estimated lifespan of the station is .
close to ten years. The estimated cost of the station will be between 35 and 37 billion.
dollars. Once completed, the station will have several pressurized living modules and will.
house up to seven astronauts. .
The station will be comprised of several major components, such as the Control.
Module. This contains two rocket engines with command and control systems. Three Nodes.
on the station connect the sections of the station together. A Service Module contains the.
life support systems and the living space for the crew during assembly. Six different.
Scientific Laboratories contain the scientific equipment and controls a robotic arm on the.
exterior of the station. This arm can manipulate the cargo of incoming shuttles. A.
Laboratory Module is where the scientific experiments take place. The low gravity makes.
many experiments possible; in the fields of microgravity, life sciences, Earth sciences, and.
Space sciences. The Truss is a long spine used to connect modules, payloads, and systems.
