International Space Station: A Space Tour
ISS or International Space Station is a space-station orbiting Earth 400 Km above the sea level with speed 27000 Km/hr. It is a joint project of countries like USA, Russia, Japan, ESA and CSA. ISS completes one revolution around Earth in just 93 minutes. That means in 24 hours it takes 15 revolutions.
Weight: 400 tons
Breath: 109 m
Length: 73 m
ISS is divided in 2 parts, American Orbital Segment (USOS) and Russian Orbital Segment (ROS).
Let's take a look at different modules of ISS:
1. Destiny:
Destiny module is built by NASA. It is used for experiments and taking photos from 151 cm window.
2. Quest:
Quest module is constructed by NASA. Quest contains Airlock system, and is used for spacewalks. Quest also houses spacewalk devices and spacesuits, also used as resting place for Astronauts.
3. Peer and Poshk:
It ia a Russian docking module. This module contains 2 docking facility and auto fuel transfer facility. Soyuz and Progros spacecrafts are docked to this module.
4. Kibo:
Kibo is biggest module of ISS developed by JAXA. Kibo is used for astronomy, biology, earth survey, developing new materials, biotechnology,etc. Kibo also has integrated X-RAY telescope. It's also provides facility to study plants and fish species.
5. Tranvility:
This module is developed by NASA. It contains life support systems and 6 berths. Tranvility is connected with Kupolo module from one side.
6. Zavezda:
Zavezda is a Russian module. It can be used as resting place for Astronauts. It can support 6 Astronauts in one module. Engines to give thrust to ISS are connected in Zavezda, as it is back module of ISS.
7. Columbus:
Columbus is developed by ESA. It contains laboratory for Genetics, Biology, Quantum Physics and Cosmology.
8. Kupolo:
Kupolo is developed by ESA, having 7 windows and facility to connect with other spacecraft. It has one robotic workstation and 80 cm window.

9. Harmony:
Harmony is built by NASA. Harmony contains 4 racks providing electric supply to space-station. Kibo and Columbus are connected with Harmony.
10. Zarya:
Zarya is Russian module used for storage purpose. Technically it acts as Cargo block. It weighs 19 tons and is connected with Unity module.
11. Unity:
Unity is NASA's first module. It provides life support systems, electric supply and resting place for Astronauts. This module has more than 60,000 mechanical items. Unity weighs 12 tons and has docking facility.
