The GOES-R weather satellite lifted off from Florida's Cape Canaveral Air Force Station today (Nov. 19) at 6:42 p.m. EST (2342 GMT), riding a United Launch Alliance Atlas V rocket to orbit. The spectacular launch, which lit up the Florida evening sky, occurred about one hour later than planned due to issues with the rocket and launch range that were swiftly resolved.
GOES-R is the first of four new advanced weather satellites that are, somewhat confusingly, collectively known as GOES-R. The U.S. National Oceanic and Atmospheric Administration (NOAA), which manages the GOES-R program, is expecting big things from all four of these spacecraft.

GOES-R is the 16th GOES (Geostationary Operational Environmental Satellite) craft to make it to space — and the satellite will be renamed GOES-16 when it reaches its final orbit, about two weeks from now. GOES satellites have been studying weather patterns from above for more than four decades; GOES-1 launched way back in October 1975. Two GOES craft, known as GOES-East and GOES-West based on their orbital positions, are doing this work now; a third GOES spacecraft is also aloft and serves as an on-orbit spare. [
The GOES satellites operate from geostationary orbit, about 22,300 miles (35,890 kilometers) above Earth's surface along the equator. At this altitude, their orbital speeds match the rotational speed of Earth, so the spacecraft can keep continuous tabs on the same stretch of land. In this case, that means the United States and much of the rest of the Western Hemisphere.

GOES-R will gather three times more data, with four times higher resolution, than comparable gear on GOES-East and GOES-West. And ABI will be able to scan the landscape five times faster to boot, NOAA officials said.
GOES-R is also the first satellite to carry a lightning mapper to geostationary orbit. This instrument will photography lightning activity throughout the Western Hemisphere about 200 times every second, NOAA officials said.
GOES-R should also increase the accuracy of forecasts in the space-weather realm, Mandt added. One of the satellite's instruments will image the surface of the sun, for instance, while others will monitor the amount of energy coming from the star and the activity of charged particles zooming near Earth.

GOES-R is designed to operate for 10 years, though it has enough fuel on board to last for 18 years, Volz said. The three GOES-R satellites yet to begin their missions — currently known as GOES-S, GOES-T and GOES-U — are scheduled to launch in 2018, 2019 and 2024, respectively.
This staggered slate should ensure that two satellites will continue collecting high-quality weather data as GOES-East and GOES-West through at least 2036, Mandt said.
The GOES-R program has a total budget of $10.8 billion through its entire life cycle, which runs from 2005 (when development began) through 2036. The project had already spent about $6.1 billion by the end of fiscal year 2015, NOAA officials have said.
The aerospace company Lockheed Martin is building the four GOES-R satellites. NOAA manages the GOES-R program, with assistance from NASA.
