The search for answers to basic questions about humanity’s place in the universe continued Saturday with the launch of NASA’s Mars Odyssey spacecraft on an epic, 286-million-mile journey to the Red Planet. The interplanetary voyage started from Cape Canaveral Air Force Station at 11:02 a.m. EDT (15:02 GMT) and is expected to take six months before the $297 million mission settles into orbit around Mars on October 24.
