(03/27/2001) --- In the early morning before dawn the 2001 Mars Odyssey spacecraft arrives at Launch Pad 17-A, Cape Canaveral Air Force Station. It will be mated with the Delta II rocket that will launch it. 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
