Today, the newest member of a family of storm-spotting satellites will head to space, carrying high-resolution cameras that will be used in real time to track everything from hurricanes and floods to wildfires and smoke, and even space weather. The GOES-T satellite is scheduled to blast off at 4:38 pm Eastern time—weather permitting, of course—on a United Launch Alliance Atlas V 541 rocket from Cape Canaveral in Florida.
“It’s a very all-purpose spacecraft. Basically, any kind of good or bad weather, any kind of hazardous environmental condition, the cameras on GOES-T will see them,” says Pamela Sullivan, director of the GOES-R program at the the National Atmospheric and Oceanic Administration, which together with NASA designed and built the new satellite. “The GOES satellites really help people every day, before, during and after a disaster.”
The new satellite will be part of a pair of eyes that spy on North America—one looking west and the other looking east. GOES-T will focus on the western continental US, Alaska, Hawaii, Mexico, some parts of Central America, and the Pacific Ocean. Its sibling, which has been orbiting since 2016, covers the eastern continental US, Canada, and Mexico.
NOAA has been maintaining this twin set of satellites (and sometimes, a triplet set) since the 1970s, retiring orbiters as they age and swapping new ones in. Once it’s in orbit, GOES-T will be renamed GOES-18, since it’s the 18th satellite in the program, and it will also be known as GOES-West, since it’s the west-looking eye. It will replace the satellite currently covering the west, which in 2018 developed a problem with its Advanced Baseline Imager, one of its most important instruments. A loop heat pipe system has been malfunctioning and not transferring enough heat from the electronics to the radiator. As a result, the heat has become a contaminant; at certain times, the infrared detectors become saturated, degrading their images.
