At Cape Canaveral Air Force Stations 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 Earths atmosphere and an experiment to study how fires burn in microgravity.
