White House: Proposed Reduced Budget for NASA, Cuts to Scientific Division, Priority Given to Human Exploration
While the Artemis II mission has conducted a close pass of the Lunar surface, the White House has announced its proposed 2027 budget for various federal agencies, including NASA. In recent months, there has been discussion about the possibility of significant cuts to the scientific division of the U.S. space agency, and in the proposal for the upcoming fiscal year, Donald Trump and his staff intend to prioritize military spending over that of other agencies.
The overall request for NASA is $18.8 billion, which represents a 23% reduction compared to 2026 levels (already considered a low budget relative to previous years). This choice reflects the U.S. administration’s desire to concentrate investments on objectives deemed strategic for American supremacy in space, sending a clear signal to adversaries, particularly China.
The document clearly states that the 2027 budget proposal "continues to support the safe and timely return of Americans to the Moon" and adds that it aims to fund "the initial elements of a permanent American presence on the lunar surface," explicitly referencing the proposal for a permanent lunar base (which will also see the involvement of the ASI). By reducing the overall budget, the "tight blanket" implies the need to sacrifice certain aspects. NASA is thus directed towards a more pragmatic approach, with fewer scientific programs and more investments in lunar infrastructure and commercial systems.
The Artemis program will particularly benefit from the new approach of the Trump administration, as stated above. For human lunar exploration and related infrastructure, there is a budget proposal of $8.5 billion, an increase of $731 million compared to 2026. The goal remains to send a human crew to the Moon's surface by 2028, likely with Artemis IV. The budget allows for the funding of lunar landers, spacesuits, surface systems, and astronaut transport. It is also stated that procedures will be simplified and unnecessary parts will be eliminated (for example, the construction of the Mobile Launcher 2 has been canceled).
A portion of the spending will be dedicated to the permanent lunar base. Specifically, there is talk of $175 million to initiate construction in the lunar south pole area (of course, the overall expenditure will be much higher). The first robotic and crewed missions will start to establish the basic infrastructures, with the goal of consolidating the American presence and paving the way for the exploitation of local resources. This should also allow for U.S. companies to create a sustainable lunar economy.
The scientific division of NASA will bear the brunt of these choices. The scaling back of the scientific portfolio leads to the elimination of over 40 missions deemed "low priority," resulting in an overall cut of $3.4 billion. Among the canceled programs is the Mars Sample Return mission, labeled as "well beyond budget" with estimated costs between $8 and $11 billion.
According to the document, the objectives of the mission could be accomplished by sending a human crew to Mars. An ambitious goal that could be achieved (optimistically) by 2040, but more likely towards 2050. Another cut has been made to SERVIR, a $10 million per year partnership with USAID, described as designed to "impose climate extremism on developing nations".
The administration would also like to cut the Space Launch System and the Orion capsule. This part of the budget has been labeled very expensive and delayed, noting that between 2005 and 2025, it absorbed nearly $65 billion while flying only once (this was the Artemis I mission, while Artemis II was launched in 2026). NASA may thus look towards commercial options offered by Blue Origin, SpaceX, or other companies.
There has also been a proposed scaling back for the International Space Station. As we know, the ISS could be deorbited between 2030 and 2032, therefore approaching the end of its operational life cycle. The proposed budget sees a reduction of $1.1 billion for maintenance and transport activities, expediting the transition towards commercial space stations and retaining only the funds necessary for the expected deorbiting around 2030.
The new proposal from the White House will need to go through the U.S. Congress, which could partially revise the figures. Meanwhile, there is great discontent within the U.S. scientific community. For example, The Planetary Society stated that it is "deeply disappointed by this budget proposal. The White House budget office has reintroduced the same budget cuts for NASA and the scientific division that were rejected last year by overwhelming bipartisan majorities in Congress. This proposal unnecessarily reintroduces an existential threat to U.S. leadership in science and space exploration," urging people to write to their political representatives in Congress to press for a review of the budget proposal.
