INTRODUCTION

• large spacecraft in orbit around Earth.

• Building the ISS began in 1998

• conduct experiments in biology, physics, astronomy,

meteorology, and other fields

ISS IN SPACE4

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

• Exploration5

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.

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.

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

9

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

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

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

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.

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

❖ 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.

17

Integrated Truss Structure18

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

19

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

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

Windows

Primary Structures22

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.

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.
