The Low-Energy Neutral Atom (LENA) Imager instrument on the IMAGE spacecraft detects energetic neutral atoms (ENAs) with energies between 10 eV and 500 eV. LENA's primary role is to image the outflow of low-energy ions from the polar ionosphere. Thomas E. Moore, of the NASA Goddard Space Flight Center, is the lead investigator for the LENA experiment.
