NASA recently made the decision to select two proposals for its astrophysical probe missions, the Advanced X-ray Imaging Satellite (AXIS) and the Probe far-Infrared Mission for Astrophysics (PRIMA). This selection has raised questions within the scientific community, with some fearing that these missions are not on an equal footing. Faced with these concerns, the space agency defended its approach, saying that these choices aim to balance the astrophysics portfolio and respond to the priorities established by experts in the field. NASA officials say these missions promise significant scientific discoveries that will expand our understanding of the universe.
There NASA recently defended its decision to select two proposals for further study as part of its astrophysical probe mission, despite criticism from the scientific community regarding the evaluation of these projects. Announced on October 3, the selection process saw the missions AXIS (Advanced X-ray Imaging Satellite) and PRIMA (Probe far-Infrared Mission for Astrophysics) will each receive $5 million in funding to refine their designs over a period of one year. NASA plans to choose one of the missions for a planned launch in 2032. According to the director of NASA’s astrophysics division, the choice of these missions was aimed at balancing the agency’s astrophysics portfolio and aligning with priorities established scientists. Although questions remain about the fairness of the proposals in terms of technological readiness, NASA maintains that both projects offer scientific opportunities that cannot be achieved with smaller exploration missions.
the justification of NASA’s choices for astrophysical probe missions
There NASA recently announced its selection of two proposals for astrophysical probe missions, AXIS and PRIMA, projects that aim to enrich our understanding of the universe. To do this, each mission received funding of $5 million for a one-year study, in order to refine its designs before the final choice planned for 2026. This approach is part of the program APEX, designed to bridge the gap between small-scale missions and larger ones like the James Webb Space Telescope.
A central aspect of this selection is its desire to guarantee diversity scientist. By opting for missions that explore both X-ray and far-infrared imaging, NASA affirms its commitment to supporting additional investigations. This strategic choice directly responds to the priorities established by the scientific community in the Astro2020 report, aiming to maximize information feedback while diversifying observation techniques.

NASA, through the voice of Mark Clampin, director of the astrophysics division, defended its choices by highlighting the need to maintain a balance within its astrophysics portfolio. He explained that the selection of the two chosen missions ensures both scientific soundness and effective use of technologies. Clampin countered concerns expressed by some in the astrophysics community, suggesting that the missions were on a equal footing in terms of technological preparation.
However, questions have arisen around the classification proposals. During the debates, members of the committee raised doubts about the equality of opportunities between the selected projects. Many believe that one of the missions received a lower rating compared to other projects not selected. In response, Clampin recalled that NASA was not limited to choosing only missions rated at the highest level, thus remaining faithful to the quest for quality of scientific investigations.
the impact of nasa’s choices on astrophysical research
Ultimately, NASA’s decision to retain AXIS and PRIMA shows its commitment to projects that go beyond simple explorations, but which strive to fill fundamental gaps in the field of astrophysics. Each mission offers unique capabilities that promise to revolutionize our understanding of cosmic phenomena. By supporting these bold initiatives, NASA wants to encourage increased collaboration within the scientific community, thus allowing a synergy of knowledge.
While debate continues over the fairness of the selection process, it is clear that NASA’s choices are intended to maximize the possible scientific contributions of these missions. By involving more scientists in the use of these new technologies, NASA is ensuring broad participation and exploitation of the missions that will be launched in the years to come, thus shaping the future of space research.
