The United Launch Alliance Atlas V rocket carrying NASA’s Mars Atmosphere and Volatile EvolutioN, or MAVEN, spacecraft is transported along the roadway from the Vertical Integration Facility to the pad at Space Launch Complex 41 on Cape Canaveral Air Force Station in Florida. Rollout began on schedule with first motion at 9:57 a.m. Launch is scheduled for Nov. 18 during a window that extends from 1:28 to 3:28 p.m. Once positioned in orbit above the Red Planet, MAVEN will study its upper atmosphere in unprecedented detail.
