What is debris mitigation and why is it required?

• A. It is the process of removing debris from Earth's atmosphere
• B. It is unrelated to space operations
• C. Practices to avoid creating or adding debris; to protect satellites and maintain space environment sustainability
• D. It increases debris for testing

Answer: (C)

Debris mitigation means putting in place practices to limit the creation of space debris and to reduce the growth of debris in orbit, so satellites can operate safely and the space environment remains usable for future missions. This includes designing missions to minimize leftover fragments, preventing fragmentation events, and arranging for end-of-life disposal such as deorbiting or moving to a graveyard orbit. The goal is to protect active satellites, avoid collisions, and preserve long-term access to space.

That description fits here because it directly states avoiding the creation or addition of debris and emphasizes protecting satellites and the sustainability of the space environment. The other options don’t fit: removing debris from Earth’s atmosphere isn’t how space debris is managed, debris mitigation is clearly related to space operations, and increasing debris for testing runs counter to the purpose of mitigation.
