## Trump’s Proposed 2026 NASA Budget: ISS Cuts, Mars Focus, and a Boost for SpaceX?

The Trump administration has unveiled its budget proposal for NASA in 2026, outlining a significant shift in priorities. The plan proposes substantial cuts to the International Space Station (ISS) program and Earth science initiatives, while simultaneously increasing funding for Mars-focused missions, potentially benefiting Elon Musk’s SpaceX.

The proposed budget slashes $508 million from the ISS, leading to a reduction in crew size and a refocusing of its research efforts towards supporting Moon and Mars exploration. Furthermore, space science missions would see a reduction of $2.265 billion, including the termination of the Mars Sample Return mission, with the administration arguing that human missions to Mars would achieve the same objectives.

However, amidst these cuts, the proposal earmarks $1 billion for “Mars-focused programs,” without specifying exactly how this funding would be allocated. This has led to speculation that SpaceX could be a major beneficiary, potentially seeking NASA funding for an uncrewed Starship flight to Mars, a mission Musk claims is planned for next year.

Beyond Mars, the budget allocates $7 billion for lunar exploration. However, it also suggests phasing out NASA’s Space Launch System (SLS) rocket and Orion capsule in favor of commercial alternatives. The Lunar Gateway program would also be terminated after the Artemis III mission, according to NASA’s own statement on the budget.

The budget also targets Earth science, proposing a $1.161 billion cut that would eliminate funding for projects like “low-priority climate monitoring satellites.” Similarly, spending on “climate-focused ‘green aviation’” would be reduced by $346 million, with those funds being redirected to air traffic control and defense spending. Funding for STEM engagement programs would also see a cut of $143 million.

Russell Vought, director of the US Office of Management and Budget, submitted the budget proposal to the Senate Committee on Appropriations, emphasizing that a “full fiscal plan” would follow. However, as *Ars Technica* points out, Congress ultimately holds the responsibility for drafting and approving the final budget.

The proposed budget has drawn criticism from some quarters. Casey Dreier, chief of space policy at the Planetary Society, described it as “the largest single-year cut to NASA in American history,” arguing that it signals a shift away from American leadership in space exploration.

While the proposed budget outlines the Trump administration’s vision for NASA’s future, its fate ultimately rests with Congress. The coming months will be crucial in determining the final direction of the agency’s priorities and the impact on its various programs.
