From non-functioning satellites, to fragments as small as a millimetre, the European Space Agency says there’s more than 8,000 tonnes of debris in Space. As the near-orbit of Earth becomes more crowded, the likelihood of satellite collisions is increasing. Even tiny debris can cause catastrophic damage to functioning satellites, as fragments may be travelling at speeds of 28,000 kilometres an hour. We rely on satellites every day, from hearing the latest news, to using GPS to navigate, so it’s important that they keep functioning.
