GeoXO Program Cuts Satellites and Instruments to Reduce Costs

The Government Accountability Office reported that the Geostationary Extended Observations program underwent a major restructuring. The National Oceanic and Atmospheric Administration initially planned for six satellites with a lifecycle cost of $19.6 billion.

Commerce directed the program office to implement the restructuring in August 2025. Commerce approved the new baseline in April 2026. The new baseline reduces satellites from six to four and instruments from five to two. The expected lifecycle cost decreased to $13 billion.

There is a risk of a gap in satellite data continuity. If the first GeoXO satellite launches as expected in 2032, the current spare satellite is projected to meet the end of its life in October 2032. This is several months before the first GeoXO satellite is fully operational. There may be several months when NOAA does not have an operational spare satellite.

The program office has yet to complete an independent cost estimate for the updated cost baseline. It is unclear whether the $13 billion estimate is reasonable. The prior lifecycle cost estimate of $19.6 billion from 2022 partially met three and substantially met one of the best practices for a well-documented estimate.

The program fully incorporated leading practices for requirements management. NOAA partially incorporated leading practices for contingency planning. The plan was missing an impact analysis for potential failure scenarios and specific actions for contingency strategies.

NOAA and NASA did not document the assessment of readiness for key technologies for three new instruments. The program did not develop a comprehensive report with results of the technology readiness assessment as required by NASA guidance.
