You're also designing a com-system that will allow astronauts constant radio contact with Earth. But you know that direct transmissions won't work--not always.

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...
