For several years, NASA, the flagship of American space exploration, has found itself in the midst of a budgetary turmoil that could well compromise the future of its scientific projects. Under Donald Trump’s presidency, a dynamic of reallocation of funds has emerged, prioritizing above all the manned conquest of Mars to the detriment of numerous fundamental scientific missions. This strategy, seemingly geared toward the “grand adventure” of space, actually conceals a series of drastic cuts to budgets dedicated to research and observation, jeopardizing a scientific legacy built over several decades. It is striking to note that, while the Starship program developed by SpaceX, backed by Elon Musk, is benefiting from an additional billion dollars, disciplines such as astrophysics, heliophysics, and Earth sciences are suffering drastic cuts of up to more than 50%. This threatens to threaten iconic telescopes and potentially revolutionary future missions. The budgetary imbalance imposed by the Trump administration is generating palpable concern in the national and international scientific community, to the point that some European partners, such as the European Space Agency (ESA), are already anticipating repercussions on their own programs in cooperation with NASA.
In a context where space science has always been a major driver of knowledge and technological progress, the fragmentation of funding for NASA projects raises profound questions: to what extent can this policy hinder the search for exoplanets, the understanding of the Earth’s climate, or even the astrophysical observations that have forged the American space agency’s worldwide reputation? These are all issues revealed in this uncertain period, where the rivalry between political ambitions and scientific imperatives is severely testing the sustainability of space missions, and the very hope of balanced and sustainable space exploration.
Drastic Cut in NASA’s Science Budget: A Chasm for Space Exploration
Let’s face it: the budget proposal submitted by the Trump administration in 2025 for fiscal year 2026 contains a surprise, to say the least… a slightly worrying one. Indeed, this plan calls for a 50% cut in funding for NASA’s scientific missions, a real drain on key fields such as astrophysics, heliophysics, planetology, not to mention research related to Earth sciences and climate. The only exception to this bloodletting: manned Martian exploration, which will see its budget increase by a billion dollars. This paradox illustrates a clear political will: to prioritize the spectacular dimension, with a vision focused on Mars and manned flight, to the detriment of fundamental science, which nevertheless serves as the foundation for all rigorous space planning.
Such an imbalance is far from trivial. To understand the issues, we must examine the sectors particularly affected. Astrophysics, which could have led to major discoveries about the origin of the universe, is facing a 68% funding cut. Heliophysics, which observes phenomena related to our Sun, is facing a 43% drop. Planetary science is suffering a 30% reduction, while Earth and climate sciences, vital for understanding the mechanisms of climate change, are seeing their funding shrink by 53%.
Thus, entire swathes of knowledge are at risk of collapse, to the great dismay of researchers, but also of industrial partners such as Lockheed Martin, Boeing, Northrop Grumman, Raytheon, Sierra Nevada Corporation, and Aerojet Rocketdyne, which jointly develop space technologies and scientific instruments. 📉

| Space Telescopes Under Pressure: Hubble, James Webb, and Nancy Roman Face Cutbacks | As a whole, NASA’s astrophysics program is the most exposed to budget cuts. While the legendary Hubble and James Webb telescopes continue their operations, they are paradoxically partially protected from cuts. Indeed, interrupting these active missions would not only be costly but also counterproductive given the billions already invested. That said, even operations related to JWST, if that name rings a bell, are threatened with a 20% cut in their planning budget, which could harm the telescope’s overall scientific performance. More worrying is the situation of the Nancy Roman Space Telescope, often described as Hubble’s successor. Nearly ready for launch in 2027, this ambitious project aims to explore the mysterious nature of dark matter by mapping its role in the development of galaxy clusters. Trump’s budget proposal threatens to simply cancel this program, causing panic in the astrophysics community. As the complementarity between the Nancy Roman and the European Euclid telescope reminds us, abandoning or delaying this project would have international repercussions. | At the same time, the space community is also concerned about the impact on the development of future telescopes, which could see their funding cut out without further ado. Serious questions therefore arise about the future of high-precision space observation, which is essential to scientific progress. 🔭 | Hubble | and |

However, this essential aspect of space research is seeing its ambitions severely curtailed. Several projects dedicated to the study of exoplanets, planets orbiting distant stars, are threatened by current budgetary restrictions. |
| The Habitable Worlds Observatory, a flagship project dedicated to the detection of biosignatures—such as oxygen or methane in planetary atmospheres—is directly targeted. This space telescope was supposed to provide the scientific equivalent of JWST on these unknown worlds. Pandora, a small space telescope designed to analyze the atmospheres of exoplanets observed as they pass in front of their stars, is also in the spotlight. Finally, Excite, another instrument specific to hot gas giants, is seeing its future called into question, even though its development is already well advanced. This is a real slap in the face for the astronomy community, many of whom regret this redirection of funds toward human-scale ambitions rather than fundamental research. Because, beyond prestige, it is knowledge about the potential origin of life that is threatened, a quest that could well enrich our understanding of Earth’s place in the universe. 🪐 | Habitable Worlds Observatory | Threatened with Cancellation | 🔬 | Pandora |

| End of Participation Considered | This tense atmosphere is echoed by French scientific leaders, who have expressed their fears about these attacks on space science in various interviews and public reports (see https://viralmag.fr/trump-contre-la-science-inquietudes-francaises/). | https://www.youtube.com/watch?v=HYEh8IbYuiU | Impact on the International Space Station and Human Spaceflight |
| The International Space Station, a symbol of collaboration between several space powers for more than two decades, is not immune to the turmoil. The Gateway project, which aims to establish a station in lunar orbit to prepare for future Martian missions, could see its American participation reduced or even canceled. This scenario seriously complicates international coordination of human spaceflight. | The lack of funding is also affecting the development of systems designed to make these flights safer and more efficient. Suppliers such as SpaceX, Boeing, and Blue Origin, the main players in New Space, are involved, but a redistribution of resources committed to the Station and supersonic flight technology is less certain. It should be remembered that these companies are major partners of NASA in the field of human spaceflight, but the current priority is clearly given to Mars projects to the detriment of other sectors. | Furthermore, reduced space research budgets could slow innovation in hostile environment survival, onboard resource management, or the study of the impact of radiation on astronauts, thus reinforcing a climate of uncertainty regarding the safety of long-term missions. | 🚀 Gateway project in lunar orbit threatened |

| Slowed innovation | Private space industry favored: the rise of SpaceX and partners in a tense context | While the cuts deemed severe speak volumes about a prioritization policy, an obvious counterpart is also the rise of private companies like SpaceX, led by Elon Musk, and its allies in the race to Mars. Increased support for the development of Starship, the reusable spacecraft key to humanized Mars exploration, reflects a clear strategy. In this equation, other manufacturers such as Blue Origin, Virgin Galactic, Aerojet Rocketdyne, and Sierra Nevada Corporation also see their futures dependent on human spaceflight projects, sometimes to the detriment of scientific research. | This development reflects a notable shift, with NASA becoming less of an organization focused on pure research and more of a facilitator for commercial and political ambitions. The partnership between SpaceX and the current administration illustrates this shift, which is very real, even if controversial. |

As astrophysicist Sylvestre Maurice pointed out at a recent conference, projects such as JWST have often survived repeated threats before reaching orbit. Fingers must therefore be crossed that science is not sacrificed on the altar of political ambitions. | Outlook and Uncertainties for NASA’s Future | Faced with these difficulties, observers wonder what the future holds for NASA. In theory, projects such as Voyager 1, still operational, or the increased monitoring of threatening asteroids, will continue. However, a shift towards an agency more focused on manned Martian missions seems to be increasing, raising questions about the real place of robotics, basic research and planetary sciences in American strategy. |
|---|---|---|---|
| Uncertainties abound and room for maneuver is limited, especially since the Trump administration is pursuing a deliberately aggressive policy line, clearly preferring to avoid spending on climate monitoring at all costs, preferring instead to focus on what it considers a “national priority”: the ambitious conquest of Mars. | In this context, several expert engineers, supported for example by companies like Michelin, which specialize in rover technology development, are closely monitoring budgetary developments, which could delay or even alter previous ambitions. The priority given to SpaceX may seem to be gaining ground, while other sectors such as space chemistry and the detection of new extreme bacteria in space continue to interest researchers, but with necessarily constrained budgets. | Will NASA remain a global beacon of space science, or will it become a more political and commercial agency?
