  skos:definition """The Medium-Energy Neutral Atom (MENA) Imager instrument on the IMAGE 
spacecraft detects energetic neutral atoms (ENAs) in the energy range 1-30 keV.
Like HENA, MENA provides images of the ring current, near-Earth plasma sheet,
and the nightside injection boundary. In addition, it images the ion
populations of the cusp. The lead investigator for the MENA experiment is Craig
J. Pollock, of Southwest Research Institute.
