There are working satellites in space, and there are non-functional satellites: what's called space junk or space debris.

This is not the first incident of space junk appearing in East Africa.

In fact, though, human space exploration and industrialization has polluted the area around our planet, with the resulting debris known as space junk.

Because this space junk poses serious risk to astronauts and infrastructure in space — as well as presenting problems on the ground for people using GPS, cell phone data and weather monitoring — scientists are determined to fix this mess.

There are already 17 sustainable development goals and the scientists are urging an 18th that would promote space conservation and sustainment of Earth's orbit, particularly to prevent the accumulation of space junk.
