10. What is
Space Station??
• Research facility in space being assembled
in Low Earth Orbit
• A complete home to the humans beyond the
Earth
• Two space stations are
in orbit; the International
space station, and China's
Tiangong 1

11. It includes
• Joint project between NASA (USA), JAXA
(Japan), RKA (Russia), ESA(Europe), CSA
(Canada) and small contributions from others
• Effects of long-term space exposure on the
human body
• Ultrasound scans and diagnosis and
treatment of medical conditions in space
• Study on cosmic rays, cosmic dust, antimatter
and dark matter in the universe

12. Construction of ISS
& ISSModules
• ISS construction started with the help of Russian
Space Station Mir on 20 November 1998 and is
scheduled to complete by 2011 end
• Zarya(20.11.1998)
• Unity node
• Zvezda (Russia)
• Destiny
(U.S Laboratory)

13. Power Supply
• The source of electrical power for the ISS is the sun
• Sunlight is converted into electricity by solar arrays.
• Solar arrays are arranged as four pairs of wings, and
each wing is capable of generating nearly 32.8 kW of
DC power
• Has rechargeable nickel-hydrogen batteries working
life of 6 years

14. Conclusion
Ensure that a quality future will be left to our children as
we make difficult decisions regarding natural resource
consumption.
