You can watch the launch of the Earth-observation satellite live.

The launch of the GOES-T weather satellite is scheduled to take place today at 4:58 pm in Florida, during a two-hour window that opens at 4:30 pm. The time is 2137 GMT.

You can watch the launch live at Space.com or via the space agency. The coverage will start at 4 pm. The time is 2200 GMT.

Satellites can see signs of climate change.

The launch of the satellite will be managed by NASA, but it will be operated by the U.S. National Oceanic and Atmospheric Administration.

The Western Hemisphere's most sophisticated weather-observing and environmental-monitoring system, the GOES-R Series, has three satellites.

The program provides advanced imagery and atmospheric measurements, real-time mapping of lightning activity and monitoring of space weather.

About 22,300 miles (35,900 kilometers) above Earth's surface is where GOES-T will go. The satellite will be renamed after it gets there. After mission managers check out the systems and scientific instruments of GOES-18, it will enter service as GOES-West. It will become an expendable spare. The terminology is very confusing.

The two satellites will work together to watch over more than half the globe, from the west coast of Africa to New Zealand.
