Overview
- NASA was instructed to plan to House-proposed FY2026 levels near $24.84 billion, a sharp contrast to the White House request of $18.81 billion.
- The House framework sets science at roughly $6 billion, with Earth science reduced to $1.33 billion from $2.14 billion.
- Funding is preserved for several missions, extending operations for New Horizons and for OSIRIS-APEX ahead of its 2029 Apophis encounter.
- The White House proposal seeks to cancel SLS and Orion in favor of commercial systems, terminate Mars Sample Return, cut $244 million from the Roman Space Telescope, and end the lunar Gateway.
- Lawmakers have signaled resistance to key cancellations, and the ultimate outcome will depend on negotiations that could still change NASA’s plans.
