Completed International Space Station and its primary elements

Requires a football field to accommodate ISS on the ground.
Huge construction flies in space !

Maximum of six people.
ISS incorporates various functions and ideas to allow astronauts to work safely.
The primary areas the astronauts utilize are five "experiment modules" which are for working, and research, and a habitation module where they live. Inside the module, the atmosphere is kept almost the same as on the ground so that astronauts can survive in shirts sleeve style. Solar panels are attached to generate power, and a robot arm will be used to support the tasks outside the ISS. A maximum of seven astronauts can be accommodated.

Remote Manipulator System
Remote Manipulator System will be utilized to mate large parts, such as modules, to ISS.
It moves along the truss structure located in the center of the ISS.

A node is a joint which connects modules to each other.
Until the habitation module (Service Module) is available, the node-1 will be used as a living area.
Later it will be used as a storage area so that it will be fully utilized.
In addition to the Node, a docking module is also used to connect parts.

Photovoltaic Arrays
Photovoltaic Arrays are used daily on Earth. In space, solar panels also receive sunlight and generates power. The panel will be rotated to face the sun all the time.

Habitation Module
This is where astronauts live. Astronauts from participating countries use this area in common.

Experiment Module
Astronauts conduct experiments or research here. The working area contains various devices.
