With U.S. military demand waning in coming years, United Launch Alliance has multiple openings in its Atlas 5 launch manifest in 2017 and 2018 available to commercial customers with as little as three months’ notice, according to company officials.

SpaceX scrubbed an attempt to launch a commercial Falcon 9 rocket Sunday less than a minute before liftoff, blaming a sensor issue on the vehicle’s first stage and pushing back the company’s first national security mission for the U.S. government at least 24 hours.

This mission follows a similar model of processing used during the Rapid Response Trailblazer (RRT-1) mission, which saw the launch of the GPS 3 Space Vehicle 07 (SV-07) spacecraft on a Falcon 9 instead of a United Launch Alliance Vulcan rocket as originally planned.
