(04/02/2001) --- At Launch Complex 17-A, Cape Canaveral Air Force Station, workers begin placing the Delta rocket fairing around the Mars Odyssey spacecraft. NASA’s latest explorer carries three scientific instruments to map the chemical and mineralogical makeup of Mars: a thermal-emission imaging system, a gamma ray spectrometer and a Martian radiation environment experiment. The imaging system will map the planet with high-resolution thermal images and give scientists an increased level of detail to help them understand how the mineralogy of the planet relates to the land forms. In addition, Odyssey will serve as a communications relay for U.S. and international landers arriving at Mars in 2003/2004. The Mars Odyssey is scheduled for launch April 7, 2001, at 11:02 a.m. EST
