SpaceX’s Dragon supply ship wrapped up a 29-day stay at the International Space Station on Tuesday, departing the complex with nearly 3,700 pounds of research specimens, a balky spacesuit and experimental 3D printed parts before re-entering the atmosphere and splashing down in the Pacific Ocean.

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.
