Space debris - efforts to clean up space

The European Space Agency (ESA) is part of an international effort to monitor and – ultimately – tackle space debris. This junk – accumulated in orbit since the dawn of the space age sixty years ago – poses an increasing risk to operational spacecraft.

ESA is developing missions to tackle the problem to help prevent a serious collision in space. The Agency is also monitoring possible dangers caused by fragments of redundant spacecraft falling to Earth, such as China’s space station Tiangong-1 – due to enter the atmosphere in the coming months.
