4. SPACE DEBRIS
• space waste
• the collection of defunct objects in orbit
around Earth
5. collisions among the catalogued objects
voluntary debris generation
break-ups in orbit
long lived debris in the protected zones
Loss of money
6. MINIMIZING DEBRIS CREATION
Minimize the release of
mission-related objects
Avoid the occurrence of break-
ups in space
Avoid collisions between
sizable space objects
Actively remove intact space
objects or debris
7. Mission Design
• to avoid debris creation
• limit the orbital lifetime of spacecraft
8. Satellite and Hardware Design
• To prevent the on-orbit break-ups energy
storage should be made passive or quiescent at
end of life because
a) Residual propellants
b) Pressure vessels and
other high pressure devices
c) Batteries
Are stored energy sources which may explode!
