OBBBA supplemental NASA Artemis and Mars program funding expires, putting future deep-space missions at risk

The One Big Beautiful Bill Act provided supplemental funding for NASA's Artemis lunar program and Mars mission development through September 30, 2032. The funding covers crewed lunar surface missions under Artemis III and IV, development of the lunar Gateway space station, and early-stage Mars architecture work. Without reauthorization or new appropriations, NASA's deep-space programs revert to baseline discretionary funding levels that budget analysts say are insufficient to maintain the current launch cadence. Artemis missions depend on the Space Launch System and Orion spacecraft, both of which require sustained multi-year funding commitments to operate. The expiration coincides with Social Security trust fund exhaustion projections, creating competing pressure on the federal budget.
