NASA will provide coverage of the prelaunch and launch activities of the National Oceanic and Atmospheric Administration’s (NOAA) next weather observing and environmental monitoring system satellite. Currently known as GOES-T, this is the third satellite in NOAA’s Geostationary Operational Environmental Satellites (GOES) – R series.

GOES-T is scheduled to launch at 4:38 p.m. EST Tuesday, March 1, on a United Launch Alliance Atlas V 541 rocket from Space Launch Complex-41 at Cape Canaveral Space Force Station in Florida. There is a two-hour launch window.

Due to the ongoing coronavirus pandemic, all media participation in news conferences will be remote. A phone bridge will be provided for each briefing.

Live launch coverage will begin at 4 p.m. on NASA Television, the NASA app, and the agency’s website. NASA will hold a science briefing at 1 p.m. Friday, Feb. 25, followed by a prelaunch news conference at 1 p.m. Saturday, Feb. 26.

GOES-T will be renamed GOES-18 once it reaches geostationary orbit. Following a successful orbital checkout of its instruments and systems, GOES-18 will go into operational service as GOES-West. In this position, the satellite will provide critical data for the U.S. West Coast, Alaska, Hawaii, Mexico, Central America, and the Pacific Ocean.

Full mission coverage is as follows:

Public Participation

Members of the public can register to attend the GOES-T launch virtually. The virtual guest program for this mission also includes curated launch resources, notifications about related opportunities or changes, and a stamp for the virtual guest passport following a successful launch.

GOES-T Virtual Social

As launch preparations are finalized, the public is invited to join a virtual GOES-T Social on Facebook. Stay up to date on the latest mission activities, interact with NOAA, NASA and GOES-T team members in real-time, and watch the launch of the ULA Atlas V rocket that will boost GOES-T toward its destination.

NOAA oversees the GOES-R Series Program through an integrated NOAA-NASA office, managing the ground system, operating the satellites, and distributing their data to users worldwide. The launch is managed by NASA’s LSP, based at Kennedy. NASA’s Goddard Space Flight Center in Greenbelt, Maryland, oversees the acquisition of the GOES-R satellite and instruments. Lockheed Martin designs, creates, and tests the GOES-R Series satellites. L3Harris Technologies provides the main instrument payload, the Advanced Baseline Imager, and the ground system, which includes the antenna system for data reception.
