One of the many friends of the Andamooka Observatory and Woomera Baker Observatory is teacher, opal miner and astronomer Dave Roe-Simons. Known as ‘Dave the mad scientist’, Dave teaches science and mathematics at Roxby Downs Area School by day and assists with tours by adding his knowledge of astronomy, local deep-time geology and geography, and local micro life, not seen by the naked eye. DTMS (as he is referred to), is an enthusiastic member of the team, who has set up radio telescopes at the Andamooka Observatory (and his home in Andamooka). Dave is driving the practical experience aspect of science at observatory so that further terrestrial and space studies may be enjoyed by both tourists and local students alike.
