The mission logo for the Orbital ATK CRS-6 mission is visible on the payload fairing encapsulating a Cygnus spacecraft as it is prepared for its move from the Vertical Integration Facility at Cape Canaveral Air Force Station's Space Launch Complex 41. Mounted atop a United Launch Alliance Atlas V rocket, the vehicle will be moved to the launch pad. The Cygnus spacecraft will boost a resupply mission delving science payloads to the International Space Station.

At Cape Canaveral Air Force Station's Space Launch Complex 41, a United Launch Alliance Atlas V rocket with a single-engine Centaur upper stage stands ready to boost an Orbital ATK Cygnus spacecraft on a resupply mission to the International Space Station. Science payloads include the second generation of a portable onboard printer to demonstrate three-dimensional printing, an instrument for first space-based observations of the chemical composition of meteors entering Earth’s atmosphere and an experiment to study how fires burn in microgravity.
