Orbital ATK’s Pegasus XL rocket will take about eight minutes to reach orbit with NASA’s eight CYGNSS weather research microsatellites, then comes deployment of the spacecraft more than 300 miles (500 kilometers) above Earth.
The 51,000-pound (23-metric ton) rocket will drop from the belly of a modified L-1011 carrier plane, named Stargazer, flying on an east-southeast path over the Atlantic Ocean at an altitude of 39,000 feet (11,900 meters).
The Pegasus rocket, launching on its 43rd orbital mission, will fire three solid-fueled stages in succession, then release the eight Cyclone Global Navigation Satellite System spacecraft two at a time.
The images below were recorded from a previous flight.

China successfully launched a Gaofen optical observation satellite Sunday toward a perch more than 22,000 miles over the equator, where it will use an Earth-facing telescope to collect remote sensing images, Chinese state media said.
Rocket Lab said Tuesday it will push back the first commercial launch of its light-class Electron rocket from New Zealand by a few weeks to address a problem uncovered during a recent fueling test.
The launch vehicle Orbital ATK wants to face off against SpaceX and United Launch Alliance for lucrative U.S. military contracts would be made of two internally-built solid rocket motors and an upper stage engine supplied by Blue Origin, the entrepreneurial space firm led by Jeff Bezos, an Orbital ATK official said this week.
