Hard X-ray spectrometer that will investigate particle acceleration in solar flares.
IMPRESS is a hard X-ray spectrometer sponsored by the National Science Foundation that will investigate particle acceleration in solar flares. It will perform soft and hard X-ray spectroscopy of solar flares in the rising phase of Solar Cycle 25. Solar flares play an important role in the origins of space weather that can affect the near-Earth environment.
