NASA pivots to Moon base, adds nuclear‑powered Mars ship to roadmap

scienceMar 24, 2026

New NASA Administrator Jared Isaacman announced a major policy pivot, replacing the planned orbital Gateway with construction of a sustained lunar base on the Moon. He also added a nuclear-powered Mars spacecraft to NASA's exploration roadmap and directed funding toward its development. The shift reconfigures NASA's near-term architecture, prioritizing surface infrastructure and advanced propulsion over orbiting platforms. That change will drive new budget choices, alter international partnerships, and increase technical risk while enabling longer crewed missions.
