If you live anywhere near an IMAX theater, it is well worth the trip to see the newly released Disney production, "Roving Mars". Made specially for the 6-story high IMAX screen and surround- sound experience, it is, as one would expect for an armchair interplanetary journey, a visually breathtaking adventure. Apart from the visuals, interspersed with real still photos snapped by the mars rovers "Spirit" and "Opportunity", even more impressive is the up close and personal emotional triumph of the engineering undertaking itself, highlighted most effectively with portrayals of the elation felt by the staff of the Jet Propulsion Laboratory as that history-making "first signal" emerged from the nerve-racking silence of the control center when "Spirit" touched down intact. After a string of disappointments (two thirds of all Mars ventures ended in failure), it had to be sweat. "Roving Mars" is playing in most IMAX theaters everywhere.
