Space Junk and the Kessler Syndrome

What is the primary concern with space debris?

• It poses a risk of collisions with operational satellites.

• It can cause light pollution.

• It increases the Earth's gravitational pull.

• It can block sunlight from reaching Earth.

What is the Kessler Syndrome?

• A method to clean up space debris.

• A chain reaction of collisions in space.

• A new type of satellite technology.

• A theory about the expansion of the universe.

How can large pieces of space debris be tracked?

• By sending astronauts to collect them.

• By using drones.

• Using ground-based radar and optical methods.

• Through satellite imaging.

What is a significant challenge in tracking space debris?

• The debris is invisible to radar.

• Small debris cannot be tracked effectively.

• The debris moves too slowly.

• The debris is too large to track.

What percentage of catalogued space junk is from US rocket stages?
