"Detecting satellites and space debris with the Murchison Widefield Array"

Many aspects of our daily life, from communication and navigation, to economic and social stability, are dependent on communication with satellites in Earth orbit. These satellites are under threat from space debris which can prematurely degrade or destroy them. The Murchison Widefield Array (MWA) has detected terrestrial radio reflected off space debris, providing a new method with which to monitor this threat. In this talk I’ll introduce the MWA and discuss how we can use it to detect and monitor space debris in order to strengthen our space situational awareness.
