WASHINGTON — NASA is revamping a major series of Earth science missions, delaying some and relying more on international partners for others to reduce costs.

As part of NASA's fiscal year 2025 budget proposal released March 11 , the agency said it was restructuring the Earth System Observatory line of missions. Those missions are intended to collect data on "designated observables" identified by the Earth science decadal survey in 2018 .

As recently as December, NASA said it was moving ahead with four of the missions : Atmosphere Observing System (AOS)-Storm, AOS-Sky, Surface Biology and Geology, and Mass Change, now called GRACE-C. A fifth mission, Surface Deformation and Change, was in an extended study phase.
