The eagle-eyed satellite, launched as a partnership between the National Oceanic and Atmospheric Administration (NOAA) and NASA, will lift off on United Launch Alliance's Atlas V rocket from Cape Canaveral Air Force Station in Florida. The 2-hour launch window opens at 5:02 p.m. EST (2202 GMT), and you can watch the launch live here on Space.com, courtesy of NASA TV.
GOES-S (Geostationary Operational Environmental Satellite-S), which will be renamed GOES-West once it takes up its final orbit, will combine forces with GOES-East to provide a full picture of the weather over the United States. It will be the second high-tech satellite to launch in the GOES-R satellite series; the first launched in 2016. [Earth from Space: The Amazing Photos by the GOES-16 Satellite]
"GOES-S [is] the second in a new series of game-changing geostationary weather satellites," Tim Walsh, the acting system program director for the GOES-R satellite program at NOAA, said during a news conference Tuesday (Feb. 27). "Its coverage will include North America, Central America and all the way to New Zealand in the Pacific. [The satellite] will provide high-resolution imagery of Alaska and surrounding high-latitude areas previously unavailable or unusable from NOAA's geostationary constellation."
"When it launches on March 1 and becomes operational later this year, GOES-S will help us see the West in true high definition and, along with the remaining satellites in the series, will extend the life of NOAA's geostationary weather constellation to 2036," he added.
According to the 45th Weather Squadron at Cape Canaveral Air Force Station, there's an 80 percent chance of favorable weather. In case of a launch delay, there is a backup window at the same time tomorrow (March 2), which also has an 80-percent chance of favorable weather.
GOES-S' sister satellite, GOES-East (formerly known as GOES-16 and GOES-R), has already provided critical data during many extreme weather events over the past year, NASA and NOAA officials said at the news conference.
"GOES-16, even beyond the spectacular imagery we've had, is already proving to be a game changer, with much more refined, higher-quality data for faster, more accurate weather forecast warnings and alerts," Steve Volz, NOAA's director for satellite and information services, said during the news conference. "This means, quite frankly, more lives are saved, and better environmental information is made available for state and local officials, who, for example, may need to make decisions about when to call for evacuations when life-threatening storms or wildfires occur."
GOES-S is set to extend that range, giving NOAA powerful weather data across even more of the globe to track weather as it develops.
