NOAA-DOD weather satellite partnership and GeoXO program cuts

Purpose

The House Science, Space, and Technology Subcommittee on Environment held this hearing to examine how NOAA's weather satellite programs support national security, focusing on data-sharing partnerships with the Air Force and Navy and on recent changes to NOAA's next-generation GeoXO geostationary satellite program. Members questioned NOAA leadership about descoped satellite instruments, canceled contracts, and workforce reductions, while military witnesses described their reliance on NOAA data. Begins at0:19:50

Who spoke

Chairman Scott Franklin (R-FL)0:19:50: Opened the hearing describing NOAA's satellite architecture as vital to national security, citing that ~95% of weather forecasting data comes from satellites0:22:22, and later questioned witnesses on JCSDA coordination0:52:25 and GOES satellite reimbursement details1:06:18.

Ranking Member Gabe Amo (D-RI)0:23:46: Criticized NOAA for not notifying Congress before canceling GeoXO satellite instruments and cutting the constellation from three to two satellites0:24:41; entered into the record a letter from former NESDIS official Dr. Steve Volz, placed on administrative leave, warning of risks from commercial data purchases and reduced system performance0:26:470:27:12; later pressed Ms. Parker on which contracts were canceled0:56:41 and cited the FY26 CJS funding agreement's requirement for advanced sensors on both East and West satellites0:59:55.

Chairman Brian Babin (R-TX), Full Committee Chairman0:28:28: Recounted the Eisenhower-Kennedy anecdote on weather forecasting's role in D-Day0:28:59, and noted NOAA transfers retired GOES satellites to DOD at no cost while DOD reimburses only operations and maintenance0:30:20; later asked Colonel Mundhenk about DOD's early-morning orbit responsibility following DMSP's planned September 2026 shutdown1:02:42.

Ranking Member Zoe Lofgren (D-CA), Full Committee0:32:40: Cited California's 2025 wildfire toll of 8,036 fires, over half a million acres burned, and 31 lives lost0:33:05; described the Defense Meteorological Satellite Program (DMSP) and its abrupt July termination and later delay to fall0:35:390:36:05; discussed lessons from the failed NPOESS program0:36:57.

Ms. Irene Parker, NOAA/NESDIS Deputy Assistant Administrator for Systems0:39:56: Testified NOAA satellites cover 500 miles to 1 million miles from Earth, enabling 10-day terrestrial and 3-day space weather forecasts0:40:20; confirmed two GeoXO instruments (ocean color, atmospheric composition) were descoped and their BAE contracts terminated0:57:37; said NESDIS lost 198 of its workforce in 2025, ending the year with 644 federal employees, while still launching the SWFO space weather mission1:18:47.

Colonel Bryan Mundhenk, USAF Chief, Weather Operations Division0:43:34: Described leading a 4,100-member Air Force weather community reliant on NOAA data flowing through the World Meteorological Organization global system0:44:31; said responsibility for the early-morning orbit now rests with the Space Force following its creation1:03:41.

Dr. Christopher Ekstrom, Deputy Chief of Naval Operations for Information Warfare / Navy Oceanographer0:48:05: Said over two-thirds of data in the Navy's forecast system originates from or through NOAA0:49:00; warned that loss of NOAA satellite command-and-control and data dissemination would immediately degrade naval operations, including anti-submarine warfare accuracy1:33:041:35:33.

Rep. Deborah Ross (D-NC)1:07:19: Highlighted NOAA's role during Hurricane Helene, including flood inundation mapping that led to a hospital evacuation and saved lives1:09:291:09:59; asked Parker how GeoXO's hyperspectral infrared sounder would improve hurricane forecasting1:10:21.

Rep. Jeff Hurd (R-CO)1:13:08: Questioned Parker on the future of GOES-R's lightning mapper as NOAA transitions to GeoXO, noting the current instrument remains capable through the mid-2030s while NOAA evaluates satellite versus ground-based lightning detection1:13:151:13:53.

Rep. Don Beyer (D-VA)1:16:43: Pressed Parker on NOAA/National Weather Service workforce cuts, including 550 vacant positions from hiring freezes and early retirements1:17:11; asked Mundhenk and Ekstrom how a $1.5 billion budget cut proposed in the president's budget would affect the weather war-fighting partnership1:19:39.

Rep. David Rouzer (R-NC)1:22:01: Asked how NOAA coordinates with the Department of War on installation and training activities in coastal North Carolina1:22:30; questioned Parker on satellite data security practices with international partners, including "zero trust" ingest protocols and NIST 800-53 rev 5.2 standards1:24:341:25:38.

Rep. April McClain Delaney (D-MD)1:27:43: Noted signing a bipartisan letter to NOAA Administrator Jacobs on data assimilation funding1:28:44; asked about NASA Goddard workforce losses, citing a report that Goddard lost over 34% of its civil servant and contractor workforce in the past year1:31:19.

Rep. Nick Begich (R-AK)1:33:10: Asked whether pending CJS appropriations would satisfy NOAA's mission requirements1:33:10; questioned Parker on coronal mass ejection risks and infrastructure hardening against a Carrington-level geomagnetic storm1:36:08.

Rep. Bill Foster (D-IL)1:38:12: Raised concerns about exospheric density affecting satellite orbital decay amid growing low-Earth-orbit deployments, including the proposed "Golden Dome" missile defense system, and the risk of adversaries using nuclear detonations to deorbit satellites via atmospheric heating1:39:061:39:40.

Key moments

NOAA descoped ocean color and atmospheric composition instruments from GeoXO and terminated the associated BAE contracts, reducing the program to a two-satellite constellation with the imager as the core instrument on both East and West0:57:370:58:21.

Ranking Member Amo revealed that Dr. Steve Volz, former NESDIS assistant administrator, was placed on administrative leave in July without explanation and submitted a letter warning the canceled upgrades would degrade system performance0:25:560:27:12.

Parker confirmed NOAA is reimbursed by DOD only for operations and maintenance costs of transferred GOES satellites, not launch costs, and that NOAA always maintains an on-orbit spare1:06:181:07:04.

DMSP's civilian data provision was abruptly terminated last July amid hurricane season, sparking public outcry, before DOD pushed the sunset back to this fall0:36:050:36:32.

Parker testified NESDIS lost 198 employees in 2025, ending the year with 644 federal staff, while asserting core mission functions were sustained1:18:47.

Parker disclosed that NASA's Joint Agency Satellite Division oversight role at NASA headquarters was eliminated to streamline "duplicative oversight" between NOAA and NASA Goddard1:01:41.

Ekstrom testified over two-thirds of the Navy's forecast-system data originates from or through NOAA, a deliberate policy choice validated by the Joint Requirements Oversight Council rather than duplicating capabilities within DOD0:49:00.

Lofgren cited that the flash floods in Texas last summer killed 138 people, underscoring the stakes of maintaining adequate satellite coverage on both East and West0:58:44.

Rep. Foster warned that low-cost adversary actions, such as detonating a nuclear device in the upper atmosphere, could heat and drag down hundreds of billions of dollars in commercial and military low-Earth-orbit assets1:39:40.

Neither Colonel Mundhenk nor Dr. Ekstrom could specify concrete impacts of a proposed $1.5 billion budget cut on the weather war-fighting partnership, deferring to ongoing interagency communication1:19:391:21:07.
