Video: Juno’s countdown to Jupiter

An early bird rocket launch from the Florida spaceport will take to the skies before dawn Saturday when an Atlas 5 lofts a classified U.S. government satellite.

Beginning the National Reconnaissance Office’s campaign of four launches in 2016 using boosters big and small to deploy a varied collection of new intelligence satellites, a Delta 4 rocket stands ready for liftoff before sun-up Wednesday from California.
