KENNEDY SPACE CENTER, FLA. - From a burst of fire and smoke, the Delta II launch vehicle races into the sky carrying the second Mars Exploration Rover, Opportunity. The bright glare briefly illuminated Florida Space Coast beaches. Opportunity’s dash to Mars began with liftoff at 11:18:15 p.m. Eastern Daylight Time from Cape Canaveral Air Force Station, Fla. The spacecraft separated successfully from the Delta's third stage 83 minutes later, after it had been boosted out of Earth orbit and onto a course toward Mars.
