Earth's Western Hemisphere | NOAA/NASA

The first imagery from the Advanced Baseline Imager (ABI) of NOAA’s GOES-17 satellite has made its public debut. | May 31, 2018: GOES-17 took this stunning, full-disk imagery of Earth’s Western Hemisphere from its checkout position at 12:00 p.m. EDT on May 20, 2018. GOES-17 observes Earth from an equatorial vantage point approximately 22,300 miles above the surface.

While experts continue to address an issue with the cooling system of the satellite’s imager, new views from GOES-17 show that its ABI is providing beautiful—and useful—imagery of the Western Hemisphere. This imagery was created using two visible bands (blue and red) and one near-infrared “vegetation” band that are functional with the current cooling system performance.

The imagery also incorporates input from one of the ABI’s “longwave” infrared bands that is functional during a portion of the day despite the cooling system issue.

When combined as a “GeoColor” image, depicting the Earth in vivid detail and colors intuitive to human vision, these bands provide valuable information for monitoring dust, haze, smoke, clouds, fog, winds and vegetation. ABI imagery also provides information on cloud motion, helping meteorologists monitor and forecast severe weather and hurricanes. The improved resolution and faster scanning ability of the instrument compared to the previous generation of GOES allow forecasters to more rapidly detect and analyze storms as they are developing and intensifying.

GOES-17 is the second in a series of next-generation geostationary weather satellites. Like GOES-16, its sister satellite operating as GOES East, GOES-17 is designed to provide advanced imagery and atmospheric measurements of Earth from 22,300 miles above the equator.

GOES-17 launched on March 1, 2018, from NASA’s Kennedy Space Center. The satellite is currently in its post-launch checkout and testing phase, the period in which its instruments and systems are calibrated, validated and assessed for operational usage. Imagery released from GOES-17 during the post-launch testing phase should be considered preliminary and non-operational.

NOAA’s operational geostationary constellation—GOES-16, operating as GOES-East, GOES-15, operating as GOES-West and GOES-14, operating as the on-orbit spare—is healthy and monitoring weather across the nation each day.

Note: This is preliminary, non-operational data as GOES-17 undergoes on-orbit testing.

NASA Goddard Space Flight Center enables NASA’s mission through four scientific endeavors: Earth Science, Heliophysics, Solar System Exploration, and Astrophysics. Goddard plays a leading role in NASA’s accomplishments by contributing compelling scientific knowledge to advance the Agency’s mission.
