What are space debris and their dangers?

Space debris, also known as space junk or orbital debris, refers to the defunct satellites, fragments from spacecraft, and other objects that are orbiting Earth. These debris come from various sources such as old rocket stages, non-functional satellites, and even collisions between objects in space.

Dangers of Space Debris

One of the major dangers posed by space debris is the risk of collision with operational satellites, spacecraft, and the International Space Station. Even small fragments of debris can cause significant damage or destruction upon impact due to the high speeds at which they travel in orbit.

Collision Risk

The increasing amount of space debris raises the likelihood of collisions, which not only endanger astronauts and space missions but also generate more debris in the process, further exacerbating the issue.

Space Pollution

Space debris also contributes to space pollution, making it more challenging for future space missions to operate safely and efficiently. This pollution can hinder the advancement of space technologies and exploration efforts.

Space Sustainability

Addressing the dangers of space debris is crucial for ensuring the sustainability of space activities and the long-term viability of space exploration. Efforts are underway to track and mitigate the impact of space debris through debris removal technologies and regulations for responsible satellite disposal.
