Forecasters are hoping a satellite will help them track future hurricanes.
The "Joint Polar Satellite System-one" was launched from Vandenberg Air Force, California, Saturday morning.
It's the first in a series of four next-generation U.S. weather satellites.
It's expected to help meteorologists not only make more accurate weather forecasts, but the satellite should also help them better predict where future hurricanes are headed.
Emergency workers will use images from space as well, to visualize the damage and power outages after storms.
