The European Space Agency (ESA) is plotting the demise of the SMART-1 lunar probe, the first ever European mission to the moon. ESA says the probe, which has been orbiting our largest natural satellite for almost 16 months, will be crashed into the surface on 3 September.
The craft, launched in September 2003, was designed to test a variety of new technologies, including an ion-propulsion engine which could one day be used for interplanetary travel. Its six month mission began when it arrived in its lunar orbit in November 2004. The mission was later extended by a year.
