Orbital ATK plans to launch its next two commercial resupply missions to the International Space Station on Atlas 5 rockets, grabbing a launch slot in March after a next-generation U.S. weather satellite was delayed, industry officials said.

A day after an explosion that destroyed an Orbital Sciences Antares rocket carrying a space station cargo ship, officials said Wednesday they hope to zero in on the likely cause of the mishap within a week or so, based on a detailed review of telemetry, analysis of video and inspection of debris.

Orbital ATK shipped the final major piece of hardware for the next Cygnus space station resupply mission to a launch base on Virginia’s Eastern Shore last week as technicians began loading cargo destined for delivery to the orbiting research lab.
