The International Space Station (ISS) is a large spacecraft in low Earth orbit that serves as a microgravity laboratory. It was built through an international collaborative project involving space agencies from the United States, Russia, Japan, Canada, and Europe. Key components of the ISS include pressurized modules that house crew members, laboratories, and living quarters, as well as structural elements like integrated truss segments that provide power and structural support. Life support systems on the ISS recover water and oxygen to sustain the crew members living and working aboard the orbiting laboratory.

3. INTRODUCTION
• large spacecraft in orbit around Earth.
• Building the ISS began in 1998
• conduct experiments in biology, physics, astronomy,
meteorology, and other fields

5. PURPOSE OF ISS
• Scientific Research
serves as a microgravity and space environment
research laboratory
• Education and Cultural Approach
by running student-developed experiments, allows
making of educational demonstrations
• Exploration

6. SIZE OF ISS
• The space station has the volume of a five-bedroom
house
• It is able to support a crew of six people, plus visitors.
• On Earth, the space station would weigh almost 450
Tonnes.

8. INTERNATIONAL PARTNERS
• involving the U.S., Russia, Canada, Japan, and the
participating countries of the European Space Agency
• one of the most ambitious international collaborations
ever attempted.
• has been visited by astronauts from 18 countries—and
counting.

9. STATION SYSTEM
❖ Life support
The critical systems are
• Water Recovery system
• Air Revitalisation System
• Oxygen Generating System
(Elektron)
❖ Power and thermal Control
❖ Communication and Computer Systems

10. Water Recovery System
The ISS has two water recovery systems.
•Zvezda contains a water recovery system that processes
waste water from showers, sinks, and other crew systems
•The Urine Processor Assembly uses a low pressure
vacuum distillation process to compensate for the lack of
gravity and thus aid in separating liquids and gasses.
10

11. Air Revitalisation System
•Carbon dioxide and trace contaminants are removed by the
Air Revitalisation System.
Oxygen Generating System(Elektron)
•designed to electrolyze water from the Water Recovery
System to produce oxygen and hydrogen.
•oxygen is delivered to the cabin atmosphere and the
hydrogen is vented overboard. 11

12. Power and Thermal Control
•Double-sided solar, or Photovoltaic arrays, provide electrical
power for the ISS.
•These bifacial cells are more efficient and operate at a
lower temperature than single-sided
•collects sunlight on one side and light reflected off the Earth
on the other.
12

13. Communication and Computer Systems
•Radio communications provide telemetry and scientific data
links between the station and Mission Control Centers.
•Radio links are also used
 during rendezvous and docking procedures
 for audio and video communication between
crewmembers, flight controllers and family members.

15. STRUCTURE OF ISS
❖ ISS was taken into space piece-by-piece and assembled
in Orbit.
❖ It consist of modules and connecting nodes that contain
living quarters and laboratories

17. ❖ Integrated Truss Structure
• The Integrated Truss Structure acts as a backbone for the
International Space Station.
• The trusses are used to support the solar arrays and
Pressurized Modules.
• the Integrated Truss Structure will contain 10 segments
and support 16 solar array panels.

19. Pressurised Structures
•designed to protect the crew from the environment of
space.
• provide a workable atmosphere for crewmembers and
house experiments, payloads and tools for protection. .
•Pressurized modules supply crewmembers with protected
mobility throughout the ISS

20. Primary Structures
(Provide structural integrity to ISS)
Ring frames: supplies structural support for pressurized
modules
Longerons: Supplies structural support for pressurized
modules' walls
Shell panels: Forms the outer walls of pressurized modules
and provide passive protection.
20

21. Integrated Trunnions: Linear mounted brackets used for
pressurized module attachment.
Windows

23. Secondary Structures
(designed to transfer their loads to primary structures)
Grappling Fixtures: provide a secure connection for
a robotic arm
Hand Rails: to be grasped by the hand so as to provide
stability or support
Hatches: pressurized structural openings which allow
crewmembers to transfer themselves and objects between
two pressurized segments.

Assembly of ISS

25. CONCLUSION
•The ISS is arguably the most expensive single item ever
constructed.
•The cost was expected to be ten trillion Rupees.
•Funding runs out in 2024.
•It will probably be disassembled or be destroyed via reentry.
