The Atlas rocket to launch four formation-flying spacecraft for NASA in March began to take shape Wednesday at the assembly building adjacent to the Complex 41 pad.

After years of analyses and debate, NASA announced Monday that the agency’s next Mars rover will land on or near an ancient river delta where water once flowed into a 30-mile-wide, 1,600-foot-deep crater to search for signs of ancient microbial life and to continue ongoing studies of the red planet’s history and evolution.

A space-bound NASA satellite was hauled aboard a military transport aircraft from a Southern California factory to the launch site in Florida on Friday and its United Launch Alliance Atlas 5 rocket booster arrived by sea from the manufacturing plant in Alabama today.
