Multiple choice

What is the primary source of orbital debris?

  1. Abandoned satellites

  2. Rocket bodies

  3. Collision fragments

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Orbital debris originates from various sources, including abandoned satellites, rocket bodies, collision fragments, and other space debris. These objects can remain in orbit for decades or even centuries, posing a threat to active satellites.

Multiple choice

Which of the following is NOT a method used to mitigate orbital debris?

  1. Active debris removal

  2. Passive debris removal

  3. Collision avoidance maneuvers

  4. Space debris shields
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Space debris shields are not a method used to mitigate orbital debris. Active debris removal, passive debris removal, and collision avoidance maneuvers are commonly employed techniques to reduce the amount of orbital debris.
