Extra-terrestrial excavation: Canadian tele-operated mining tech challenges for the Moon.

After two years in which no prizes had been claimed, three teams met the NASA-devised 2009 Regolith Excavation Challenge with modifications of previous designs. Features of the first-time Laurentian Rock entry, by secondary school and undergraduate students from Laurentian and Queen's universities in Canada, are briefly described and illustrated; difficulties overcome included the 4-second delay in remote control, while innovations included a polymer lithium battery and a hemispherical immersive display screen.
