NASA celebrated the full restoration of its Guam Remote Station on September 10, completing over three years of recovery following the devastation caused by Super Typhoon Mawar in May 2023. The station, a critical component of NASA’s Tracking and Data Relay Satellites (TDRS) and the Near Space Network, had been severely damaged, impacting communication with spacecraft.
The Category 4 typhoon, packing 185 mph winds and over 28 inches of rain, destroyed two 16.5-meter antennas and damaged an 11-meter antenna and the Inter Facility Link building. This damage created a “Zone of Exclusion,” cutting TDRS coverage to approximately 85% of a spacecraft’s orbit and risking up to 20 minutes of lost contact with the International Space Station per orbit. NASA responded with emergency repairs to the least-damaged antenna and borrowed mobile terminals from the U.S. Army to partially restore service, enabling a November 2023 spacewalk.
Engineers completed the final and most complex step of the rebuild on July 1, returning the station’s central antenna to service. Congress allocated disaster-relief funding in early 2025 to rebuild the ground station and reinforce the network against future storms. Construction, which began that summer, concluded in summer 2026. The same funding also supported critical upgrades at three other Near Space Network ground stations.
At a ribbon-cutting ceremony, Jena Garrahy, SCaN Deputy Program Manager for Network Operations, stated that the return to service represents “far more than the restoration of a critical piece of infrastructure.” Representatives from NASA’s SCaN Division and local leaders joined the Guam station workforce to commemorate the event. The Guam team was recognized for its work in debris removal, site security, and maintaining NASA’s connection to its missions during the outage and rebuild. A companion ceremony at NASA’s White Sands Complex in Las Cruces, New Mexico, honored the engineers and specialists who supported the recovery efforts remotely.
