Satellite Cuts Threaten US Weather Forecasting Progress

Planned reductions to the United States' next-generation weather satellite program could weaken forecasting capabilities and leave critical observation gaps, according to a Government Accountability Office (GAO) report released in October 2026. The changes affect the National Oceanic and Atmospheric Administration's (NOAA) Geostationary Extended Observations (GeoXO) program, which NOAA is developing with NASA to replace existing satellites beginning in the 2030s.

The program's projected lifecycle costs have fallen from $19.6 billion to $13 billion following changes directed by the Trump administration in 2025. The GAO warned that existing spacecraft could reach the end of their service lives before the first GeoXO satellite enters operation in 2032, potentially leaving the country without essential satellite observations for several months.

According to the GAO report, the restructuring raises questions about scheduling, contingency planning, technology readiness and whether the replacement system will preserve the capabilities of the current fleet. NOAA has not provided a response to CNN's request for comment, as reported on October 19.

The revised plan reduces the planned constellation from six satellites to four and removes three of the five scientific instruments originally intended for each spacecraft. NOAA's updated configuration calls for operational coverage over the eastern and western United States, supported by a backup satellite, instead of the original plan for three operational satellites covering the eastern, central and western regions.

The GAO questioned whether the redesigned system would deliver improvements over the existing GOES-R series. The report stated, "It is unclear whether GeoXO will improve, or even continue, the functionality available in the current generation of satellites."

The first GeoXO spacecraft, scheduled to launch in 2032, is expected to carry a visible and infrared imager for monitoring storms during the day and night, along with an infrared sounder that measures atmospheric conditions, including wind speed, wind direction and humidity. However, the initial satellite will not include several instruments planned for the original design.

One major omission is an upgraded Geostationary Lightning Mapper, a technology first deployed on a GOES satellite in 2017. The existing instrument detects lightning flashes and supports tornado prediction, monitoring the rapid intensification of tropical storms and hurricanes, aviation forecasting and wildfire monitoring.

The revised program also removes instruments designed to monitor air quality, including wildfire smoke, and examine water quality, ocean currents and harmful algae blooms. CNN reported that the changes partly reflect an effort to narrow the satellites' focus to weather forecasting rather than broader climate research.

Steve Volz, former head of NOAA's satellite division and chief executive of Earth-observation consulting firm HyperionEO LLC, warned that the cuts could slow US progress as other countries develop forecasting technology. He said the removed instruments would have addressed "stated requirements from Congress."

Volz emphasized that demand for reliable atmospheric information has increased over the past decade.

"Our need for weather information is much greater now than it was ten years ago," Volz said.

He also warned that reducing the program's scientific capabilities could leave the United States behind Europe, Japan and China in efforts to improve forecast accuracy.

House Science Committee ranking member Zoe Lofgren and Democratic member Gabe Amo separately challenged the changes in a letter sent to NOAA Administrator Neil Jacobs on October 19, 2026. The lawmakers requested documents, including any cost-benefit analyses examining the consequences of removing instruments from GeoXO.

The lawmakers warned that the administration's changes could undermine the next generation of US weather observation technology.

"Thanks to the Trump Administration, the next generation of America's weather satellites could very well be worse than the current ones," Lofgren and Amo wrote.

They also argued that the reductions would affect more than the program's budget, pointing to the potential consequences for scientific monitoring and forecasting.

"Two fewer satellites and three fewer scientific instruments are not line items in a budget. They represent a concrete, tangible weakening of America's ability to understand the weather, the climate, and the world around us," the lawmakers wrote.

House Science, Space, and Technology Committee Chairman Brian Babin took a different emphasis in a statement responding to the GAO report on October 16, 2026. He welcomed the administration's restructuring as a potential response to the report's concerns while stressing the importance of congressional oversight.

"Taxpayers deserve accountability for major federal investments, especially when critical weather forecasting capabilities are at stake," Babin said.

Babin said the report highlighted the need to monitor costs, schedules and risk management. He added that the effects of the restructuring on expenses, delivery timelines and uninterrupted weather observations remained unresolved.

"We are hopeful that the Administration's recent restructuring of the program will address many of the concerns identified in this report. However, questions remain about how those changes will affect the program's overall cost, timeline, and ability to provide uninterrupted weather data. This Committee will continue working to ensure NOAA manages this investment responsibly and preserves the satellite capabilities our nation depends on," Babin said.
