CENTER, FL – Less than 2 weeks after the
dinnertime blastoff of the GOES-S weather observatory put on a stunningly
delicious launch display from the Florida Space Coast on March 1, 2018, the revolutionary
satellite that will track extreme weather in near real time reached geostationary
orbit and was renamed as GOES-17.

will operate for the remainder of its planned 15 year lifetime.

forecasts and warnings on weather, wildfires, tornadoes and cyclones for
California and the western United States all the way out to Hawaii and Guam in
ways that will positively impact the lives of everyday people as well as save
lives by helping pinpoint outbreaks of severe weather in near real time.

22,236 miles above the equator. NOAA maintains a two-satellite Geostationary
Operational Environmental Satellite (GOES) constellation to watch over the
Western Hemisphere. The satellites circle the Earth in geosynchronous orbit,
which means they orbit the Earth’s equatorial plane at a speed matching the
Earth’s rotation. This allows them to stay in a fixed position in the sky,
remaining stationary with respect to a point on the ground. Credit: NOAA/NASA
