There is a lot of junk orbiting the Earth and the problem will worsen unless there are changes in how spacecraft operators operate. But it is not all doom and gloom. The first steps toward a comprehensive solution are already well underway including a European code of conduct for space debris mitigation.
According to Dr Ruediger Jehn, a space debris specialist working at ESA's Space Operations Centre (ESOC) in Darmstadt, there are several relatively simple measures that will help reduce the amount of debris in space. Some are already being implemented by spacecraft operators at little or no cost.
