Trump Makes Major Cuts to NASA’s Lunar Missions
US President Donald Trump in his 2026 budget proposal, aims to cut $6 billion from NASA’s funding, a 24% reduction from its current $24.8 billion. This significant cutback targets the Artemis moon program, a central part of NASA’s plans to return humans to the lunar surface.
Under the proposal, NASA’s costly Space Launch System (SLS) and Orion crew capsule will be phased out after their third mission in 2027. These systems, developed by Boeing, Northrop Grumman, and Lockheed Martin, have long been criticised for their high costs and delays. The White House described them as “grossly expensive,” with SLS alone costing $4 billion per launch and 140% over budget since development began in 2010.
Shift Toward Mars Exploration
While the lunar program faces setbacks, the budget boosts NASA’s Mars-focused efforts. The administration has proposed an additional $1 billion for Mars-related projects, reflecting a shift in priorities. This aligns with the vision of SpaceX CEO Elon Musk, who aims to send humans to the Red Planet.
SpaceX’s Starship rocket, key to Musk’s Mars ambitions, is already set to land astronauts on the moon in 2027. The new budget suggests that more cost-effective commercial alternatives like Starship will replace the SLS and Orion for future lunar missions.
Trump’s approach appears to balance pressures from Congress to maintain moon missions and calls from Musk’s supporters to focus on Mars.
International Impact and Industry Response
The proposed cuts have drawn strong criticism from scientists and industry leaders. A 47% cut to NASA’s science programs threatens ongoing projects and international partnerships. Agencies like the European Space Agency, Canada, and Japan play vital roles in Artemis missions and could be affected.
Lockheed Martin, currently building the Orion spacecraft for Artemis 4, may see up to $4 billion in contracts at risk. Northrop Grumman also faces uncertainty, with its $935 million contract for the Gateway lunar station potentially cancelled. Gateway, meant to orbit the moon and support Artemis missions, may be scrapped despite having components already delivered.
NASA has indicated that existing Gateway parts can be reused in other missions, and that international partners will still be included in new plans.
Trump’s nominee for NASA Administrator, billionaire Jared Isaacman, has expressed support for the Mars-first agenda during his confirmation hearings. If confirmed, his leadership may further reshape NASA’s exploration goals.
