The United Launch Alliance barge Delta Mariner arrives at Port Canaveral, Fla. delivering the Atlas V launch vehicle that will boost the Mars Atmosphere and Volatile Evolution, or MAVEN, spacecraft to the Red Planet. MAVEN is being prepared for its scheduled launch in November from Cape Canaveral Air Force Station, Fla. atop a United Launch Alliance Atlas V rocket. Positioned in an orbit above the Red Planet, MAVEN will study the upper atmosphere of Mars in unprecedented detail.
