Enablers:

• More and more countries are launching into space. America and China are engaged in a space race to the moon, mars and beyond.
• Launch of the Galileo satellite system
• Costs of clean up
• Costs of redesigning ships
• Lack of control and standards

Inhibitors:

• New standards being adopted e.g. International Committee on Space Contamination adopts resolution that spaceflight standards for all countries should include a requirement for the space device developers to ensure the objects return from orbit.
• Becoming a bigger safety hazard to space missions
• Growing awareness
• Safety hazard on Earth from falling debris e.g. A 550-pound main propellant tank of the second stage of a Delta 2 rocket fell near Georgetown, Texas in 1997. A 156-pound piece of space debris fell near Riyadh, Saudi Arabia in 2001.

Experts:

Space exploratory scientists, space debris analysts

Timing:

• In 1995, Canada became the first country to equip one of its satellites, Radarsat, with casing and shields to protect against collisions with garbage orbiting the Earth.
• A 550-pound main propellant tank of the second stage of a Delta 2 rocket fell near Georgetown, Texas in 1997. A 156-pound piece of space debris fell near Riyadh, Saudi Arabia in 2001.
