An Apple Hot News article offers details on Maestro, a free Mac OS X scientific visualization tool created by scientists at NASA’s Jet Propulsion Laboratory (JPL) to work with the rovers Spirit and Opportunity. “During the 2004 Mars Exploration Rover Mission, you can download a free copy of Maestro for Mac OS X from NASA JPL that allows you to see Mars in ways you’ve never imagined. ‘It’s actually the same software that the scientists use to view downlink data and to plan Rover activities from day to day,’ says Gene Chalfant, technical staff member at NASA JPL.” Maestro requires Mac OS X 10.3.1 (Panther) or higher.
