NASA has selected two mission proposals to further explore X-ray and infrared wavelengths, marking the beginning of a new class of astrophysics missions. These missions are part of NASA’s Explorer Program and have each been awarded $5 million for a 12-month concept study. The final decision will be made in 2026, and the selected mission will begin in 2032.
Both mission concepts aim to explore unexplored areas of space. Nicola Fox, associate administrator for NASA’s Science Mission Directorate, emphasized the potential of these missions to advance NASA’s science goals, saying they will enable groundbreaking discoveries in line with the top priorities set by the Decadal Survey.
Advanced X-ray imaging satellite
The Advanced X-ray Imaging Satellite, led by principal investigator Christopher Reynolds of the University of Maryland, College Park, is designed to survey supermassive black holes and study stellar feedback, a process critical to galaxy evolution. The mission will build on previous X-ray observatories, offering advanced imaging techniques with a wider field of view.
Far Infrared Astrophysics Probe Mission
Another proposal is the Probe Far-Infrared Mission, led by Jason Glenn of NASA Goddard. This mission seeks to bridge the gap between current infrared observatories and radio telescopes. The 1.8-meter telescope will study far-infrared light to answer questions about planet formation, supermassive black holes and cosmic dust.
Both proposals were selected for their scientific potential and alignment with NASA’s larger goals for future space exploration. The winning mission will be the first of NASA’s new Probe Explorers missions, which are intended to fill the gap between the flagship and smaller missions.
