Trump proposes steep cut to NASA budget as astronauts head for the Moon

NASA's budget could be slashed by as much as 23 percent, representing a $5.6 billion funding cut for fiscal year 2027. The Donald Trump administration presented the proposal, which assumes a drastic reduction in spending for the space agency, just two days after the historic launch of the first crewed lunar mission in over half a century. The plan allocates $18.8 billion to NASA, which will force the cancellation of more than 40 missions deemed "low-priority." The primary objective of the new strategy is maximum concentration on the Artemis program. The White House wants American astronauts to stand on the Moon before the end of Trump's term, paving the way for the construction of a permanent Moon Base. To achieve this, the administration plans to cut funding for Science programs by nearly half, including the definitive termination of the costly Mars Sample Return project. For the creative technology and engineering sectors, this signifies a rapid shift toward commercialization. The proposal envisions replacing the SLS rocket and Orion capsule with cheaper solutions from private providers. The global implications of these changes are clear: NASA is ceasing to be an agency conducting a wide spectrum of scientific research and is becoming an organization focused on rapid, commercial success in deep space, opening vast opportunities for private giants in the Aerospace industry.
President Donald Trump's administration has presented a budget proposal for fiscal year 2027, which assumes drastic cuts for the American space agency. The proposal provides for a reduction in NASA funding by 23 percent, which translates to an amount $5.6 billion less compared to the level enacted for 2026. This document came to light just two days after a historical success — the launch of the Artemis II mission, which sent four astronauts toward the Moon, representing the first crewed flight to these regions in over half a century.
According to the presented plan, NASA's total discretionary budget for 2027 would amount to $18.8 billion. The White House argues this decision is necessary to eliminate "unnecessary and overly expensive activities," while aiming to focus all resources on one paramount goal: landing a human on the Moon before the end of Trump's term and building a permanent lunar base. This is a repeat of the strategy from last year, when similar cut proposals were decisively rejected by the Republican-dominated Congress, which maintained funding at a level close to the end of the Biden administration.
Artemis as a priority at the expense of science and technology
While the agency's overall budget is to be trimmed, the Artemis program remains intact, and even ideologically reinforced. The administration plans to allocate $8.5 billion for commercial lander systems, new spacesuits, rovers, and habitats. This strategy also assumes increasing the frequency of uncrewed commercial lander flights delivering payloads to the surface of the Silver Globe. NASA Administrator Jared Isaacman faced the difficult task of defending these proposals, emphasizing in an official statement that this budget aims to "maintain American leadership in deep space."

The price for protecting the lunar program, however, is extremely high for other sectors of NASA's operations. Scientific programs are set to suffer the most, with their funding to be reduced by nearly half — a drop of $3.4 billion. The plan assumes the cancellation of over 40 missions described as "low priority." Although the document does not list all threatened projects, it confirms the final termination of the Mars Sample Return mission, which had already been struggling with massive cost overruns. The Planetary Society described these proposals as "draconian," warning of an existential threat to American dominance in space sciences.
End of the SLS era and shift toward commercial solutions
One of the most significant elements of the new strategy is the open push to replace the Space Launch System (SLS) rocket and the Orion capsule with cheaper commercial alternatives. The White House explicitly calls these systems too costly and suggests that their replacement is crucial for the realization of more ambitious missions, such as the construction of the Lunar Base Camp. Although the SLS system will be used for several more missions (likely up to Artemis V) in accordance with the Congressional mandate, NASA plans to begin the process of procuring commercial transport services for astronauts as early as 2027.
- SpaceX Starship and Blue Origin New Glenn are mentioned as potential successors to SLS in crewed transport.
- New orders for commercial astronaut launch services are to be initiated in fiscal year 2027.
- Investments in In-Situ Resource Utilization technologies are intended to support the production of rocket fuel directly on the lunar surface.
Despite declared support for innovation, NASA's overall space technology portfolio is to be cut by $297 million. The cuts hit projects that the administration describes as "unnecessary and lacking specific applications." This is a risky game, considering that Jared Isaacman's ambitious plans for nuclear propulsion and reactors on the Moon require precisely stable, multi-year funding for research into new technologies.
Future of the ISS and education in question
The budget project also assumes a reduction in funding for the International Space Station (ISS) by $1.1 billion, aimed at maintaining the schedule for its deorbiting in 2030. This decision stands in direct contradiction to the efforts of some members of Congress, including Senator Ted Cruz, who advocate for extending the station's operation until 2032. While NASA promotes a strategy of replacing the ISS with private orbital stations, the White House proposed only a small increase in funds to support these commercial projects, raising questions about the smoothness of the transition between old and new infrastructure in low Earth orbit.
As is traditional for Donald Trump's budget proposals, the plan envisions the complete elimination of NASA's education programs. This is a move that regularly meets with resistance in Congress, as it hits projects that inspire future generations of engineers and scientists. The entire budget proposal for 2027 paints a picture of an agency that is to stop being a versatile research institute and become an efficient logistics operator focused on one goal: consolidating the US presence on the Moon using private tools.
Looking at the political dynamics in Washington, this proposal is more of an ideological manifesto than a final financial plan. Congress, which has the final say in budget matters, has repeatedly proven that it does not agree to weakening NASA's scientific role at the expense of political goals. Nevertheless, the clear emphasis on the commercialization of crewed flights and the retreat from the costly SLS system seem to be the direction that — regardless of the final amounts — will define the American space sector in the coming decade. NASA stands on the threshold of a transformation in which the agency's role as an owner and operator of hardware will finally be replaced by the role of a customer ordering services from private giants.
