ULTRASAT: NASA’s Role in Mission Development and Science

ULTRASAT is a near-ultraviolet imaging satellite with a wide field of view (200 square degrees) and an anticipated launch in late 2027. It is an international partnership led by Israel (Israel Space Agency & Weizmann Institute of Science) in partnership with the United States (NASA) and Germany (DESY). ULTRASAT will provide high cadence observations and rapid target-of-opportunity response, providing a powerful capability for time-domain and multimessenger astrophysics (TDAMM), and will have scientific applications from solar system studies to cosmology.
