The Geostationary Operational Environmental Satellite U (GOES-U) is set for launch on a SpaceX Falcon Heavy rocket from NASA’s Kennedy Space Center.
The satellite, part of NOAA’s GOES-R series, has undergone significant pre-launch preparations including attachment to the launch vehicle, fueling, and encapsulation. It aims to improve weather forecasting and space weather detection.

Launch Preparations for GOES-U Satellite
The Geostationary Operational Environmental Satellite U (GOES-U) has now passed several important milestones ahead of its upcoming launch aboard a SpaceX Falcon Heavy rocket from Launch Complex 39A at NASA’s Kennedy Space Center in Florida.
Technicians at Astrotech Space Operations facility in Titusville, Florida lifted the National Oceanic and Atmospheric Administration’s (NOAA) GOES-U satellite onto the payload adapter and the payload attach fitting on June 10, enabling GOES-U to securely attach to the top of its Falcon Heavy rocket.
Satellite Integration and Fueling
This milestone follows recent fueling operations where teams loaded over 5,000 pounds of hypergolic propellant and oxidizer into the satellite, which will be used to provide it with thrust in orbit. The GOES-U satellite now weighs a total of 10,956 pounds.
Teams next encapsulated the 20-foot-tall satellite inside two payload fairing halves in preparation for connecting it to the rocket on June 13.

Final Pre-Launch Procedures
During the ascent phase of the launch, the fairing halves will protect GOES-U from aerodynamic pressure and heating. Once GOES-U no longer requires this protection, approximately four minutes after liftoff, the halves will be jettisoned and return to Earth, where SpaceX crews will recover them for use on future missions.
After encapsulation, workers transported the spacecraft from Astrotech’s facility to NASA Kennedy and SpaceX’s hangar at the spaceport’s Launch Complex 39A, on June 15.

Launch Schedule and Mission Objectives
The next mission milestone includes connecting the encapsulated GOES-U to the SpaceX Falcon Heavy rocket ahead of rolling the stack out to the launch pad.
NASA is targeting a two-hour window opening at 5:16 p.m. EDT on June 25, for the launch of GOES-U aboard a SpaceX Falcon Heavy rocket from Launch Complex 39A at NASA Kennedy. Following launch, the spacecraft will complete a nearly three-week journey to its destination in geostationary orbit 22,236 miles above the equator, allowing the satellites to continually view the Western Hemisphere.
As the fourth and final satellite in NOAA’s GOES-R Series, GOES-U will enhance meteorologists’ ability to provide advanced weather forecasting and warning capabilities. GOES-U also will improve detection and monitoring of space weather hazards using a new compact coronagraph instrument.
NASA’s Launch Services Program, based at Kennedy, manages the launch service for the GOES-U mission. NASA’s Goddard Space Flight Center in Greenbelt, Maryland oversees the acquisition of the spacecraft and instruments. Lockheed Martin designs, builds, and tests the GOES-R series satellites. L3Harris Technologies provides the primary instrument, the Advanced Baseline Imager, along with the ground system, which includes the antenna system for data reception.
