People crowd the jetty and pier at Jetty Park, in Cape Canaveral, Florida, to watch as a Delta 2 rocket roars skyward on Saturday, carrying the Mars Odyssey spacecraft. Odyssey is scheduled to arrive at Mars in late October and begin a two-year mapping mission. Using an array of spectrometers and imagers, the spacecraft, the size of a compact car, will hunt for evidence of volcanic activity and past or present water deposits on Mars, a clue to determine whether life has ever existed on the red planet.
