The weather was favorable, all systems were go. After a week of delays, SpaceX on Sunday finally launched a satellite that will kick off a new era for GPS navigation technology.
Am - PT - SpaceX - Liftoff - Falcon
At just before 6 a.m. PT, SpaceX tweeted simply "Liftoff!" and the Falcon 9 rocket was on its way.
The rocket was carrying the US Air Force's GPS III SV01 satellite, the first in series of new satellite designs that will update the Global Positioning System. Still used and maintained by the military, the array of GPS satellites also now has become a part of the everyday fabric of life for just about everyone. It's in the palm of your hand, for instance, whenever you get directions to a store or restaurant on your smartphone.
