Workers on Launch Pad 17-A, Cape Canaveral Air Force Station, help guide the Mars Odyssey spacecraft into position for the enclosure by the fairing of the Delta II rocket already in place. The spacecraft will map the Martian surface in search of geological features that could indicate the presence of water, now or in the past, and may contribute significantly toward understanding what will be necessary for a more sophisticated exploration of Mars. Launch is scheduled for 11:02 a.m. EDT April 7
