NOAA’s GOES-T Weather Satellite, Built by Lockheed Martin, Successfully Launched

Space and Earth weather forecasting across the Western Hemisphere just got a little boost thanks to the Geostationary Operational Environmental Satellite (GOES-T), an advanced weather satellite built by Lockheed Martin for the National Oceanic and Atmospheric Administration (NOAA). The satellite successfully launched from Florida’s Space Coast at 4:38 p.m. ET.

GOES-T will be renamed GOES-18 when it reaches geostationary orbit. Once operational, GOES-18 will take GOES-17’s place tracking atmospheric rivers, floods, wildfires, drought, and other severe weather and climate phenomena over the West Coast of the United States.

Advanced Monitoring of Weather, Oceans and Climate

As climate change continues to drive more frequent and severe environmental impacts, the GOES-R satellite series – of which GOES-T is the third – uses sophisticated technology to put information in the hands of those who need it most, when they need it.

Before it starts collecting and sharing critical weather data, the satellite’s journey to space began in Littleton, Colorado, where it was designed and built by Lockheed Martin engineers.

Based on Lockheed Martin’s novel A2100 satellite bus design, the spacecraft features two high-tech instruments built by the company’s Advanced Technology Center in Palo Alto, California:

Geostationary Lightning Mapper (GLM), which is a first-of-its-kind operational lightning mapper flown into its orbit, tracking lightning across the U.S. in real-time. By collecting data on the frequency, location and extent of lightning discharges, GLM allows meteorologists to quickly identify intensifying storms and take appropriate action. In 2020, GLM captured a lightning megaflash nearly 500 miles long that broke the world record for longest lightning flash.

Solar Ultraviolet Imager (SUVI), focuses on space weather and measures the sun in extreme ultraviolet wavelength range and provides solar images. SUVI is essential to understanding active areas on the sun and predicting solar events that may disrupt power utilities, communication or navigation systems here on Earth.

Over its 10-year operational lifetime, GOES-T can produce over a terabyte of data per day and monitors severe weather continuously, supporting NOAA’s mission to provide weather data to save lives.

What’s After Lift Off?

Now that it’s in space, GOES-T will undergo an on-orbit checkout of its instruments and systems before beginning official operations in January 2023.

In addition to severe weather monitoring, it will do things like:

  • Identify volcanic eruptions, even ones under the ocean, like the recent event near Tonga
  • Measure land and sea surface temperatures to track drought conditions and warming oceans
  • Provide early alerts to emergency responders for wildfires, including those caused by lightning strikes
  • Observe solar flares that could impact telecommunication on and around Earth

With three of the four GOES-R weather satellites now launched, GOES-U, the last satellite in the series, is in production and planned for a 2024 launch.

Beyond the GOES-R series, Lockheed Martin looks forward to continued partnership with NASA and NOAA as they look ahead to future weather and climate missions.
